44e51f0ea9 feat: sync all 140 Microsoft skills with collision protection
- Add find_github_skills() to discover skills in .github/skills/ not
  reachable via the skills/ symlink tree (picks up 11 missing skills)
- Add collision protection: if a target directory exists and was not
  from a previous Microsoft sync, append -ms suffix instead of overwriting
- Microsoft mcp-builder → mcp-builder-ms (community version preserved)
- Microsoft skill-creator → skill-creator-ms (community version preserved)
- Total skills: 856 (was 845, +11 newly discovered)

They help you avoid picking from 700+ skills one by one.
They help you avoid picking from 860+ skills one by one.
What bundles are:
### ⚠️ Important: Bundles Are NOT Separate Installations!
- Recommended starting sets for common workflows.
- A shortcut for onboarding and faster execution.
**Common confusion:** "Do I need to install each bundle separately?"
What bundles are not:
**Answer: NO!** Here's what bundles actually are:
- Not a separate install.
- Not a locked preset.
**What bundles ARE:**
- ✅ Recommended skill lists organized by role
- ✅ Curated starting points to help you decide what to use
- ✅ Time-saving shortcuts for discovering relevant skills
How to use bundles:
**What bundles are NOT:**
- ❌ Separate installations or downloads
- ❌ Different git commands
- ❌ Something you need to "activate"
1. Install the repository once.
2. Pick one bundle in [docs/BUNDLES.md](docs/BUNDLES.md).
3. Start with 3-5 skills from that bundle in your prompt.
4. Add more only when needed.
### How to use bundles:
Examples:
1. **Install the repository once** (you already have all skills)
2. **Browse bundles** in [docs/BUNDLES.md](docs/BUNDLES.md) to find your role
3. **Pick 3-5 skills** from that bundle to start using in your prompts
4. **Reference them in your conversations** with your AI (e.g., "Use @brainstorming...")
For detailed examples of how to actually use skills, see the [**Usage Guide**](docs/USAGE.md).
### Examples:
- Building a SaaS MVP: `Essentials` + `Full-Stack Developer` + `QA & Testing`.
- Hardening production: `Security Developer` + `DevOps & Cloud` + `Observability & Monitoring`.

# 📖 Usage Guide: How to Actually Use These Skills
> **Confused after installation?** This guide walks you through exactly what to do next, step by step.
---
## 🤔 "I just installed the repository. Now what?"
Great question! Here's what just happened and what to do next:
### What You Just Did
When you ran `npx antigravity-awesome-skills` or cloned the repository, you:
**Downloaded 860+ skill files** to your computer (usually in `~/.agent/skills/`)
**Made them available** to your AI assistant
**Did NOT enable them all automatically** (they're just sitting there, waiting)
Think of it like installing a toolbox. You have all the tools now, but you need to **pick which ones to use** for each job.
---
## 🎯 Step 1: Understanding "Bundles" (This is NOT Another Install!)
**Common confusion:** "Do I need to download each skill separately?"
**Answer: NO!** Here's what bundles actually are:
### What Bundles Are
Bundles are **recommended lists** of skills grouped by role. They help you decide which skills to start using.
**Analogy:**
- You installed a toolbox with 860 tools (✅ done)
- Bundles are like **labeled organizer trays** saying: "If you're a carpenter, start with these 10 tools"
- You don't install bundles—you **pick skills from them**
### What Bundles Are NOT
❌ Separate installations
❌ Different download commands
❌ Something you need to "activate"
### Example: The "Web Wizard" Bundle
When you see the [Web Wizard bundle](BUNDLES.md#-the-web-wizard-pack), it lists:
- `frontend-design`
- `react-best-practices`
- `tailwind-patterns`
- etc.
These are **recommendations** for which skills a web developer should try first. They're already installed—you just need to **use them in your prompts**.
---
## 🚀 Step 2: How to Actually Execute/Use a Skill
This is the part that should have been explained better! Here's how to use skills:
### The Simple Answer
**Just mention the skill name in your conversation with your AI assistant.**
### Different Tools, Different Syntax
The exact syntax varies by tool, but it's always simple:
#### Claude Code (CLI)
```bash
# In your terminal/chat with Claude Code:
>> Use @brainstorming to help me design a todo app
```
#### Cursor (IDE)
```bash
# In the Cursor chat panel:
@brainstorming help me design a todo app
```
#### Gemini CLI
```bash
# In your conversation with Gemini:
Use the brainstorming skill to help me plan my app
```
#### Codex CLI
```bash
# In your conversation with Codex:
Apply @brainstorming to design a new feature
```
#### Antigravity IDE
```bash
# In agent mode:
Use @brainstorming to plan this feature
```
> **Pro Tip:** Most modern tools use the `@skill-name` syntax. When in doubt, try that first!
---
## 💬 Step 3: What Should My Prompts Look Like?
Here are **real-world examples** of good prompts:
### Example 1: Starting a New Project
**Bad Prompt:**
> "Help me build a todo app"
**Good Prompt:**
> "Use @brainstorming to help me design a todo app with user authentication and cloud sync"
**Why it's better:** You're explicitly invoking the skill and providing context.
---
### Example 2: Reviewing Code
**Bad Prompt:**
> "Check my code"
**Good Prompt:**
> "Use @lint-and-validate to check `src/components/Button.tsx` for issues"
**Why it's better:** Specific skill + specific file = precise results.
---
### Example 3: Security Audit
**Bad Prompt:**
> "Make my API secure"
**Good Prompt:**
> "Use @api-security-best-practices to review my REST endpoints in `routes/api/users.js`"
**Why it's better:** The AI knows exactly which skill's standards to apply.
---
### Example 4: Combining Multiple Skills
**Good Prompt:**
> "Use @brainstorming to design a payment flow, then apply @stripe-integration to implement it"
**Why it's good:** You can chain skills together in a single prompt!
---
## 🎓 Step 4: Your First Skill (Hands-On Tutorial)
Let's actually use a skill right now. Follow these steps:
### Scenario: You want to plan a new feature
1. **Pick a skill:** Let's use `brainstorming` (from the "Essentials" bundle)
2. **Open your AI assistant** (Claude Code, Cursor, etc.)
3. **Type this exact prompt:**
```
Use @brainstorming to help me design a user profile page for my app
```
4. **Press Enter**
5. **What happens next:**
- The AI loads the brainstorming skill
- It will start asking you structured questions (one at a time)
- It will guide you through understanding, requirements, and design
- You answer each question, and it builds a complete spec
6. **Result:** You'll end up with a detailed design document—without writing a single line of code yet!
---
## 🗂️ Step 5: Picking Your First Skills (Practical Advice)
Don't try to use all 860 skills! Here's a sensible approach:
### Start with "The Essentials" (5 skills, everyone needs these)
1. **`@brainstorming`** - Plan before you build
2. **`@lint-and-validate`** - Keep code clean
3. **`@git-pushing`** - Save work safely
4. **`@systematic-debugging`** - Fix bugs faster
5. **`@concise-planning`** - Organize tasks
**How to use them:**
- Before writing new code → `@brainstorming`
- After writing code → `@lint-and-validate`
- Before committing → `@git-pushing`
- When stuck → `@systematic-debugging`
### Then Add Role-Specific Skills (5-10 more)
Find your role in [BUNDLES.md](BUNDLES.md) and pick 5-10 skills from that bundle.
**Example for Web Developer:**
- `@frontend-design`
- `@react-best-practices`
- `@tailwind-patterns`
- `@seo-audit`
**Example for Security Engineer:**
- `@api-security-best-practices`
- `@vulnerability-scanner`
- `@ethical-hacking-methodology`
### Finally, Add On-Demand Skills (as needed)
Keep the [CATALOG.md](../CATALOG.md) open as reference. When you need something specific:
> "I need to integrate Stripe payments"
> → Search catalog → Find `@stripe-integration` → Use it!
---
## 🔄 Complete Example: Building a Feature End-to-End
Let's walk through a realistic scenario:
### Task: "Add a blog to my Next.js website"
#### Step 1: Plan (use @brainstorming)
```
You: Use @brainstorming to design a blog system for my Next.js site
AI: [Asks structured questions about requirements]
You: [Answer questions]
AI: [Produces detailed design spec]
```
#### Step 2: Implement (use @nextjs-best-practices)
```
You: Use @nextjs-best-practices to scaffold the blog with App Router
AI: [Creates file structure, sets up routes, adds components]
```
#### Step 3: Style (use @tailwind-patterns)
```
You: Use @tailwind-patterns to make the blog posts look modern
AI: [Applies Tailwind styling with responsive design]
```
#### Step 4: SEO (use @seo-audit)
```
You: Use @seo-audit to optimize the blog for search engines
AI: [Adds meta tags, sitemaps, structured data]
```
#### Step 5: Test & Deploy
```
You: Use @test-driven-development to add tests, then @vercel-deployment to deploy
AI: [Creates tests, sets up CI/CD, deploys to Vercel]
```
**Result:** Professional blog built with best practices, without manually researching each step!

## 🆘 Common Questions
### "Which tool should I use? Claude Code, Cursor, Gemini?"
**Any of them!** Skills work universally. Pick the tool you already use or prefer:
- **Claude Code** - Best for terminal/CLI workflows
- **Cursor** - Best for IDE integration
- **Gemini CLI** - Best for Google ecosystem
- **Codex CLI** - Best for OpenAI ecosystem
### "Can I see all available skills?"
Yes! Three ways:
1. Browse [CATALOG.md](../CATALOG.md) (searchable list)
2. Run `ls ~/.agent/skills/` (if installed there)
3. Ask your AI: "What skills do you have for [topic]?"
### "Do I need to restart my IDE after installing?"
Usually no, but if your AI doesn't recognize a skill:
1. Try restarting your IDE/CLI
2. Check the installation path matches your tool
3. Try the explicit path: `npx antigravity-awesome-skills --claude` (or `--cursor`, `--gemini`, etc.)
### "Can I create my own skills?"
Yes! Use the `@skill-creator` skill:
```
Use @skill-creator to help me build a custom skill for [your task]
```
### "What if a skill doesn't work as expected?"
1. Check the skill's SKILL.md file directly: `~/.agent/skills/[skill-name]/SKILL.md`
2. Read the description to ensure you're using it correctly
3. [Open an issue](https://github.com/sickn33/antigravity-awesome-skills/issues) with details

## 🎯 Quick Reference Card
**Save this for quick lookup:**
| Task | Skill to Use | Example Prompt |
|------|-------------|----------------|
| Plan new feature | `@brainstorming` | `Use @brainstorming to design a login system` |
| Review code | `@lint-and-validate` | `Use @lint-and-validate on src/app.js` |
| Debug issue | `@systematic-debugging` | `Use @systematic-debugging to fix login error` |
| Security audit | `@api-security-best-practices` | `Use @api-security-best-practices on my API routes` |
| SEO check | `@seo-audit` | `Use @seo-audit on my landing page` |
| React component | `@react-patterns` | `Use @react-patterns to build a form component` |
| Deploy app | `@vercel-deployment` | `Use @vercel-deployment to ship this to production` |
---
## 🚦 Next Steps
Now that you understand how to use skills:
1. ✅ **Try one skill right now** - Start with `@brainstorming` on any idea you have
2. 📚 **Pick 3-5 skills** from your role's bundle in [BUNDLES.md](BUNDLES.md)
3. 🔖 **Bookmark** [CATALOG.md](../CATALOG.md) for when you need something specific
4. 🎯 **Try a workflow** from [WORKFLOWS.md](WORKFLOWS.md) for a complete end-to-end process
---
## 💡 Pro Tips for Maximum Effectiveness
### Tip 1: Start Every Feature with @brainstorming
> Before writing code, use `@brainstorming` to plan. You'll save hours of refactoring.
### Tip 2: Chain Skills in Order
> Don't try to do everything at once. Use skills sequentially: Plan → Build → Test → Deploy
### Tip 3: Be Specific in Prompts
> Bad: "Use @react-patterns"
> Good: "Use @react-patterns to build a modal component with animations"
### Tip 4: Reference File Paths
> Help the AI focus: "Use @security-auditor on routes/api/auth.js"
### Tip 5: Combine Skills for Complex Tasks
> "Use @brainstorming to design, then @test-driven-development to implement with tests"

description: Deploy containerized applications to Azure Container Apps using Azure Developer CLI (azd). Use when setting up azd projects, writing azure.yaml configuration, creating Bicep infrastructure for Container Apps, configuring remote builds with ACR, implementing idempotent deployments, managing environment variables across local/.azure/Bicep, or troubleshooting azd up failures. Triggers on requests for azd configuration, Container Apps deployment, multi-service deployments, and infrastructure-as-code with Bicep.

# Azure Developer CLI (azd) Container Apps Deployment
Deploy containerized frontend + backend applications to Azure Container Apps with remote builds, managed identity, and idempotent infrastructure.
## Quick Start
```bash
# Initialize and deploy
azd auth login
azd init # Creates azure.yaml and .azure/ folder
azd env new <env-name> # Create environment (dev, staging, prod)
azd up # Provision infra + build + deploy
```
## Core File Structure
```
project/
├── azure.yaml # azd service definitions + hooks
├── infra/
│ ├── main.bicep # Root infrastructure module
│ ├── main.parameters.json # Parameter injection from env vars
│ └── modules/
│ ├── container-apps-environment.bicep
│ └── container-app.bicep
├── .azure/
│ ├── config.json # Default environment pointer
│ └── <env-name>/
│ ├── .env # Environment-specific values (azd-managed)
│ └── config.json # Environment metadata
└── src/
├── frontend/Dockerfile
└── backend/Dockerfile
```
## azure.yaml Configuration
### Minimal Configuration
```yaml
name: azd-deployment
services:
backend:
project: ./src/backend
language: python
host: containerapp
docker:
path: ./Dockerfile
remoteBuild: true
```
### Full Configuration with Hooks
```yaml
name: azd-deployment
metadata:
template: my-project@1.0.0
infra:
provider: bicep
path: ./infra
azure:
location: eastus2
services:
frontend:
project: ./src/frontend
language: ts
host: containerapp
docker:
path: ./Dockerfile
context: .
remoteBuild: true
backend:
project: ./src/backend
language: python
host: containerapp
docker:
path: ./Dockerfile
context: .
remoteBuild: true
hooks:
preprovision:
shell: sh
run: |
echo "Before provisioning..."
postprovision:
shell: sh
run: |
echo "After provisioning - set up RBAC, etc."
postdeploy:
shell: sh
run: |
echo "Frontend: ${SERVICE_FRONTEND_URI}"
echo "Backend: ${SERVICE_BACKEND_URI}"
```
### Key azure.yaml Options
| Option | Description |
|--------|-------------|
| `remoteBuild: true` | Build images in Azure Container Registry (recommended) |
| `context: .` | Docker build context relative to project path |
| `host: containerapp` | Deploy to Azure Container Apps |
| `infra.provider: bicep` | Use Bicep for infrastructure |
## Environment Variables Flow
### Three-Level Configuration
1. **Local `.env`** - For local development only
2. **`.azure/<env>/.env`** - azd-managed, auto-populated from Bicep outputs
3. **`main.parameters.json`** - Maps env vars to Bicep parameters
### Parameter Injection Pattern
```json
// infra/main.parameters.json
{
"parameters": {
"environmentName": { "value": "${AZURE_ENV_NAME}" },
"location": { "value": "${AZURE_LOCATION=eastus2}" },
"azureOpenAiEndpoint": { "value": "${AZURE_OPENAI_ENDPOINT}" }
}
}
```
Syntax: `${VAR_NAME}` or `${VAR_NAME=default_value}`
### Setting Environment Variables
```bash
# Set for current environment
azd env set AZURE_OPENAI_ENDPOINT "https://my-openai.openai.azure.com"
azd env set AZURE_SEARCH_ENDPOINT "https://my-search.search.windows.net"
# Set during init
azd env new prod
azd env set AZURE_OPENAI_ENDPOINT "..."
```
### Bicep Output → Environment Variable
```bicep
// In main.bicep - outputs auto-populate .azure/<env>/.env
output SERVICE_FRONTEND_URI string = frontend.outputs.uri
output SERVICE_BACKEND_URI string = backend.outputs.uri
output BACKEND_PRINCIPAL_ID string = backend.outputs.principalId
```
## Idempotent Deployments
### Why azd up is Idempotent
1. **Bicep is declarative** - Resources reconcile to desired state
2. **Remote builds tag uniquely** - Image tags include deployment timestamp
3. **ACR reuses layers** - Only changed layers upload
### Preserving Manual Changes
Custom domains added via Portal can be lost on redeploy. Preserve with hooks:
```yaml
hooks:
preprovision:
shell: sh
run: |
# Save custom domains before provision
if az containerapp show --name "$FRONTEND_NAME" -g "$RG" &>/dev/null; then
az containerapp show --name "$FRONTEND_NAME" -g "$RG" \
--query "properties.configuration.ingress.customDomains" \
-o json > /tmp/domains.json
fi
postprovision:
shell: sh
run: |
# Verify/restore custom domains
if [ -f /tmp/domains.json ]; then
echo "Saved domains: $(cat /tmp/domains.json)"
fi
```
### Handling Existing Resources
```bicep
// Reference existing ACR (don't recreate)
resource containerRegistry 'Microsoft.ContainerRegistry/registries@2023-07-01' existing = {
name: containerRegistryName
}
// Set customDomains to null to preserve Portal-added domains
customDomains: empty(customDomainsParam) ? null : customDomainsParam
```
## Container App Service Discovery
Internal HTTP routing between Container Apps in same environment:
```bicep
// Backend reference in frontend env vars
env: [
{
name: 'BACKEND_URL'
value: 'http://ca-backend-${resourceToken}' // Internal DNS
}
]
```
Frontend nginx proxies to internal URL:
```nginx
location /api {
proxy_pass $BACKEND_URL;
}
```
## Managed Identity & RBAC
### Enable System-Assigned Identity
```bicep
resource containerApp 'Microsoft.App/containerApps@2024-03-01' = {
identity: {
type: 'SystemAssigned'
}
}
output principalId string = containerApp.identity.principalId
```
### Post-Provision RBAC Assignment
```yaml
hooks:
postprovision:
shell: sh
run: |
PRINCIPAL_ID="${BACKEND_PRINCIPAL_ID}"
# Azure OpenAI access
az role assignment create \
--assignee-object-id "$PRINCIPAL_ID" \
--assignee-principal-type ServicePrincipal \
--role "Cognitive Services OpenAI User" \
--scope "$OPENAI_RESOURCE_ID" 2>/dev/null || true
# Azure AI Search access
az role assignment create \
--assignee-object-id "$PRINCIPAL_ID" \
--role "Search Index Data Reader" \
--scope "$SEARCH_RESOURCE_ID" 2>/dev/null || true
```
## Common Commands
```bash
# Environment management
azd env list # List environments
azd env select <name> # Switch environment
azd env get-values # Show all env vars
azd env set KEY value # Set variable
# Deployment
azd up # Full provision + deploy
azd provision # Infrastructure only
azd deploy # Code deployment only
azd deploy --service backend # Deploy single service
# Debugging
azd show # Show project status
az containerapp logs show -n <app> -g <rg> --follow # Stream logs
```
## Reference Files
- **Bicep patterns**: See [references/bicep-patterns.md](references/bicep-patterns.md) for Container Apps modules
- **Troubleshooting**: See [references/troubleshooting.md](references/troubleshooting.md) for common issues
- **azure.yaml schema**: See [references/azure-yaml-schema.md](references/azure-yaml-schema.md) for full options
## Critical Reminders
1. **Always use `remoteBuild: true`** - Local builds fail on M1/ARM Macs deploying to AMD64
2. **Bicep outputs auto-populate .azure/<env>/.env** - Don't manually edit
3. **Use `azd env set` for secrets** - Not main.parameters.json defaults
4. **Service tags (`azd-service-name`)** - Required for azd to find Container Apps
5. **`|| true` in hooks** - Prevent RBAC "already exists" errors from failing deploy

PersistentAgentsClient
├── Administration → Agent CRUD operations
├── Threads → Thread management
├── Messages → Message operations
├── Runs → Run execution and streaming
├── Files → File upload/download
└── VectorStores → Vector store management
```
## Core Workflow
### 1. Create Agent
```csharp
var modelDeploymentName = Environment.GetEnvironmentVariable("MODEL_DEPLOYMENT_NAME");
PersistentAgent agent = await client.Administration.CreateAgentAsync(
model: modelDeploymentName,
name: "Math Tutor",
instructions: "You are a personal math tutor. Write and run code to answer math questions.",
tools: [new CodeInterpreterToolDefinition()]
);
```
### 2. Create Thread and Message
```csharp
// Create thread
PersistentAgentThread thread = await client.Threads.CreateThreadAsync();
// Create message
await client.Messages.CreateMessageAsync(
thread.Id,
MessageRole.User,
"I need to solve the equation `3x + 11 = 14`. Can you help me?"
);
```
### 3. Run Agent (Polling)
```csharp
// Create run
ThreadRun run = await client.Runs.CreateRunAsync(
thread.Id,
agent.Id,
additionalInstructions: "Please address the user as Jane Doe."
);
// Poll for completion
do
{
await Task.Delay(TimeSpan.FromMilliseconds(500));
run = await client.Runs.GetRunAsync(thread.Id, run.Id);
}
while (run.Status == RunStatus.Queued || run.Status == RunStatus.InProgress);
// Retrieve messages
await foreach (PersistentThreadMessage message in client.Messages.GetMessagesAsync(
threadId: thread.Id,
order: ListSortOrder.Ascending))
{
Console.Write($"{message.Role}: ");
foreach (MessageContent content in message.ContentItems)
{
if (content is MessageTextContent textContent)
Console.WriteLine(textContent.Text);
}
}
```
### 4. Streaming Response
```csharp
AsyncCollectionResult<StreamingUpdate> stream = client.Runs.CreateRunStreamingAsync(
thread.Id,
agent.Id
);
await foreach (StreamingUpdate update in stream)
{
if (update.UpdateKind == StreamingUpdateReason.RunCreated)
{
Console.WriteLine("--- Run started! ---");
}
else if (update is MessageContentUpdate contentUpdate)
{
Console.Write(contentUpdate.Text);
}
else if (update.UpdateKind == StreamingUpdateReason.RunCompleted)
{
Console.WriteLine("\n--- Run completed! ---");
}
}
```
### 5. Function Calling
```csharp
// Define function tool
FunctionToolDefinition weatherTool = new(
name: "getCurrentWeather",
description: "Gets the current weather at a location.",
parameters: BinaryData.FromObjectAsJson(new
{
Type = "object",
Properties = new
{
Location = new { Type = "string", Description = "City and state, e.g. San Francisco, CA" },
Unit = new { Type = "string", Enum = new[] { "c", "f" } }
},
Required = new[] { "location" }
}, new JsonSerializerOptions { PropertyNamingPolicy = JsonNamingPolicy.CamelCase })
);
// Create agent with function
PersistentAgent agent = await client.Administration.CreateAgentAsync(
model: modelDeploymentName,
name: "Weather Bot",
instructions: "You are a weather bot.",
tools: [weatherTool]
);
// Handle function calls during polling
do
{
await Task.Delay(500);
run = await client.Runs.GetRunAsync(thread.Id, run.Id);
if (run.Status == RunStatus.RequiresAction
&& run.RequiredAction is SubmitToolOutputsAction submitAction)
{
List<ToolOutput> outputs = [];
foreach (RequiredToolCall toolCall in submitAction.ToolCalls)
{
if (toolCall is RequiredFunctionToolCall funcCall)
{
// Execute function and get result
string result = ExecuteFunction(funcCall.Name, funcCall.Arguments);
outputs.Add(new ToolOutput(toolCall, result));
}
}
run = await client.Runs.SubmitToolOutputsToRunAsync(run, outputs, toolApprovals: null);
}
}
while (run.Status == RunStatus.Queued || run.Status == RunStatus.InProgress);
```
### 6. File Search with Vector Store
```csharp
// Upload file
PersistentAgentFileInfo file = await client.Files.UploadFileAsync(
filePath: "document.txt",
purpose: PersistentAgentFilePurpose.Agents
);
// Create vector store
PersistentAgentsVectorStore vectorStore = await client.VectorStores.CreateVectorStoreAsync(
fileIds: [file.Id],
name: "my_vector_store"
);
// Create file search resource
FileSearchToolResource fileSearchResource = new();
fileSearchResource.VectorStoreIds.Add(vectorStore.Id);
// Create agent with file search
PersistentAgent agent = await client.Administration.CreateAgentAsync(
model: modelDeploymentName,
name: "Document Assistant",
instructions: "You help users find information in documents.",
tools: [new FileSearchToolDefinition()],
toolResources: new ToolResources { FileSearch = fileSearchResource }
);
```
### 7. Bing Grounding
```csharp
var bingConnectionId = Environment.GetEnvironmentVariable("AZURE_BING_CONNECTION_ID");
BingGroundingToolDefinition bingTool = new(
new BingGroundingSearchToolParameters(
[new BingGroundingSearchConfiguration(bingConnectionId)]
)
);
PersistentAgent agent = await client.Administration.CreateAgentAsync(
model: modelDeploymentName,
name: "Search Agent",
instructions: "Use Bing to answer questions about current events.",
tools: [bingTool]
);
```
### 8. Azure AI Search
```csharp
AzureAISearchToolResource searchResource = new(
connectionId: searchConnectionId,
indexName: "my_index",
topK: 5,
filter: "category eq 'documentation'",
queryType: AzureAISearchQueryType.Simple
);
PersistentAgent agent = await client.Administration.CreateAgentAsync(
model: modelDeploymentName,
name: "Search Agent",
instructions: "Search the documentation index to answer questions.",
tools: [new AzureAISearchToolDefinition()],
toolResources: new ToolResources { AzureAISearch = searchResource }
);
```
### 9. Cleanup
```csharp
await client.Threads.DeleteThreadAsync(thread.Id);
await client.Administration.DeleteAgentAsync(agent.Id);
await client.VectorStores.DeleteVectorStoreAsync(vectorStore.Id);
await client.Files.DeleteFileAsync(file.Id);
```

| `StreamingUpdateReason.RunCompleted` | Run finished |
| `StreamingUpdateReason.RunFailed` | Run errored |
| `MessageContentUpdate` | Text content chunk |
| `RunStepUpdate` | Step status change |
## Key Types Reference
| Type | Purpose |
|------|---------|
| `PersistentAgentsClient` | Main entry point |
| `PersistentAgent` | Agent with model, instructions, tools |
| `PersistentAgentThread` | Conversation thread |
| `PersistentThreadMessage` | Message in thread |
| `ThreadRun` | Execution of agent against thread |
| `RunStatus` | Queued, InProgress, RequiresAction, Completed, Failed |
| `ToolResources` | Combined tool resources |
| `ToolOutput` | Function call response |
## Best Practices
1. **Always dispose clients** — Use `using` statements or explicit disposal
2. **Poll with appropriate delays** — 500ms recommended between status checks
3. **Clean up resources** — Delete threads and agents when done
4. **Handle all run statuses** — Check for `RequiresAction`, `Failed`, `Cancelled`
5. **Use streaming for real-time UX** — Better user experience than polling
6. **Store IDs not objects** — Reference agents/threads by ID
7. **Use async methods** — All operations should be async
## Error Handling
```csharp
using Azure;
try
{
var agent = await client.Administration.CreateAgentAsync(...);
}
catch (RequestFailedException ex) when (ex.Status == 404)
{
Console.WriteLine("Resource not found");
}
catch (RequestFailedException ex)
{
Console.WriteLine($"Error: {ex.Status} - {ex.ErrorCode}: {ex.Message}");
}
```

## Core Workflow
### 1. Create Agent
```java
// Create agent with tools
PersistentAgent agent = client.createAgent(
modelDeploymentName,
"Math Tutor",
"You are a personal math tutor."
);
```
### 2. Create Thread
```java
PersistentAgentThread thread = client.createThread();
```
### 3. Add Message
```java
client.createMessage(
thread.getId(),
MessageRole.USER,
"I need help with equations."
);
```
### 4. Run Agent
```java
ThreadRun run = client.createRun(thread.getId(), agent.getId());
// Poll for completion
while (run.getStatus() == RunStatus.QUEUED || run.getStatus() == RunStatus.IN_PROGRESS) {
Thread.sleep(500);
run = client.getRun(thread.getId(), run.getId());
}
```
### 5. Get Response
```java
PagedIterable<PersistentThreadMessage> messages = client.listMessages(thread.getId());
for (PersistentThreadMessage message : messages) {
System.out.println(message.getRole() + ": " + message.getContent());
}
```
### 6. Cleanup
```java
client.deleteThread(thread.getId());
client.deleteAgent(agent.getId());
```
## Best Practices
1. **Use DefaultAzureCredential** for production authentication
2. **Poll with appropriate delays** — 500ms recommended between status checks
3. **Clean up resources** — Delete threads and agents when done
4. **Handle all run statuses** — Check for RequiresAction, Failed, Cancelled
5. **Use async client** for better throughput in high-concurrency scenarios
## Error Handling
```java
import com.azure.core.exception.HttpResponseException;
try {
PersistentAgent agent = client.createAgent(modelName, name, instructions);
} catch (HttpResponseException e) {
System.err.println("Error: " + e.getResponse().getStatusCode() + " - " + e.getMessage());
}
```

description: Build applications powered by GitHub Copilot using the Copilot SDK. Use when creating programmatic integrations with Copilot across Node.js/TypeScript, Python, Go, or .NET. Covers session management, custom tools, streaming, hooks, MCP servers, BYOK providers, session persistence, and custom agents. Requires GitHub Copilot CLI installed and a GitHub Copilot subscription (unless using BYOK).
---
# GitHub Copilot SDK
Build applications that programmatically interact with GitHub Copilot. The SDK wraps the Copilot CLI via JSON-RPC, providing session management, custom tools, hooks, MCP server integration, and streaming across Node.js, Python, Go, and .NET.
## Prerequisites
- **GitHub Copilot CLI** installed and authenticated (`copilot --version` to verify)
- **GitHub Copilot subscription** (Individual, Business, or Enterprise) — not required for BYOK
- **Runtime:** Node.js 18+ / Python 3.8+ / Go 1.21+ / .NET 8.0+
## Installation
| Language | Package | Install |
|----------|---------|---------|
| Node.js | `@github/copilot-sdk` | `npm install @github/copilot-sdk` |
| Python | `github-copilot-sdk` | `pip install github-copilot-sdk` |
| Go | `github.com/github/copilot-sdk/go` | `go get github.com/github/copilot-sdk/go` |
| .NET | `GitHub.Copilot.SDK` | `dotnet add package GitHub.Copilot.SDK` |
---
## Core Pattern: Client → Session → Message
All SDK usage follows this pattern: create a client, create a session, send messages.
### Node.js / TypeScript
```typescript
import { CopilotClient } from "@github/copilot-sdk";
const client = new CopilotClient();
const session = await client.createSession({ model: "gpt-4.1" });
const response = await session.sendAndWait({ prompt: "What is 2 + 2?" });
console.log(response?.data.content);
await client.stop();
```
### Python
```python
import asyncio
from copilot import CopilotClient
async def main():
client = CopilotClient()
await client.start()
session = await client.create_session({"model": "gpt-4.1"})
response = await session.send_and_wait({"prompt": "What is 2 + 2?"})
print(response.data.content)
await client.stop()
asyncio.run(main())
```
### Go
```go
client := copilot.NewClient(nil)
if err := client.Start(ctx); err != nil { log.Fatal(err) }
defer client.Stop()
session, _ := client.CreateSession(ctx, &copilot.SessionConfig{Model: "gpt-4.1"})
response, _ := session.SendAndWait(ctx, copilot.MessageOptions{Prompt: "What is 2 + 2?"})
fmt.Println(*response.Data.Content)
```
### .NET
```csharp
await using var client = new CopilotClient();
await using var session = await client.CreateSessionAsync(new SessionConfig { Model = "gpt-4.1" });
var response = await session.SendAndWaitAsync(new MessageOptions { Prompt = "What is 2 + 2?" });
Console.WriteLine(response?.Data.Content);
```
---
## Streaming Responses
Enable real-time output by setting `streaming: true` and subscribing to delta events.
```typescript
const session = await client.createSession({ model: "gpt-4.1", streaming: true });
session.on("assistant.message_delta", (event) => {
process.stdout.write(event.data.deltaContent);
});
session.on("session.idle", () => console.log());
await session.sendAndWait({ prompt: "Tell me a joke" });
```
**Python equivalent:**
```python
from copilot.generated.session_events import SessionEventType
session = await client.create_session({"model": "gpt-4.1", "streaming": True})
def handle_event(event):
if event.type == SessionEventType.ASSISTANT_MESSAGE_DELTA:
sys.stdout.write(event.data.delta_content)
sys.stdout.flush()
session.on(handle_event)
await session.send_and_wait({"prompt": "Tell me a joke"})
```
### Event Subscription
| Method | Description |
|--------|-------------|
| `on(handler)` | Subscribe to all events; returns unsubscribe function |
| `on(eventType, handler)` | Subscribe to specific event type (Node.js only) |
---
## Custom Tools
Define tools that Copilot can call to extend its capabilities.
### Node.js
```typescript
import { CopilotClient, defineTool } from "@github/copilot-sdk";
const getWeather = defineTool("get_weather", {
description: "Get the current weather for a city",
parameters: {
type: "object",
properties: { city: { type: "string", description: "The city name" } },
required: ["city"],
},
handler: async ({ city }) => ({ city, temperature: "72°F", condition: "sunny" }),
});
const session = await client.createSession({
model: "gpt-4.1",
tools: [getWeather],
});
```
### Python
```python
from copilot.tools import define_tool
from pydantic import BaseModel, Field
class GetWeatherParams(BaseModel):
city: str = Field(description="The city name")
@define_tool(description="Get the current weather for a city")
async def get_weather(params: GetWeatherParams) -> dict:
return {"city": params.city, "temperature": "72°F", "condition": "sunny"}
session = await client.create_session({"model": "gpt-4.1", "tools": [get_weather]})
```
### Go
```go
type WeatherParams struct {
City string `json:"city" jsonschema:"The city name"`
}
getWeather := copilot.DefineTool("get_weather", "Get weather for a city",
func(params WeatherParams, inv copilot.ToolInvocation) (WeatherResult, error) {
return WeatherResult{City: params.City, Temperature: "72°F"}, nil
},
)
session, _ := client.CreateSession(ctx, &copilot.SessionConfig{
Model: "gpt-4.1",
Tools: []copilot.Tool{getWeather},
})
```
### .NET
```csharp
var getWeather = AIFunctionFactory.Create(
([Description("The city name")] string city) => new { city, temperature = "72°F" },
"get_weather", "Get the current weather for a city");
await using var session = await client.CreateSessionAsync(new SessionConfig {
Model = "gpt-4.1", Tools = [getWeather],
});
```
---
## Hooks
Intercept and customize session behavior at key lifecycle points.
| Hook | Trigger | Use Case |
|------|---------|----------|
| `onPreToolUse` | Before tool executes | Permission control, argument modification |
| `onPostToolUse` | After tool executes | Result transformation, logging |
| `onUserPromptSubmitted` | User sends message | Prompt modification, filtering |
| `onSessionStart` | Session begins | Add context, configure session |
| `onSessionEnd` | Session ends | Cleanup, analytics |
| `onErrorOccurred` | Error happens | Custom error handling, retry logic |
### Example: Tool Permission Control
```typescript
const session = await client.createSession({
hooks: {
onPreToolUse: async (input) => {
if (["shell", "bash"].includes(input.toolName)) {
return { permissionDecision: "deny", permissionDecisionReason: "Shell access not permitted" };
}
return { permissionDecision: "allow" };
},
},
});
```
### Pre-Tool Use Output
| Field | Type | Description |
|-------|------|-------------|
| `permissionDecision` | `"allow"` \| `"deny"` \| `"ask"` | Whether to allow the tool call |
| `permissionDecisionReason` | string | Explanation for deny/ask |
| `modifiedArgs` | object | Modified arguments to pass |
| `additionalContext` | string | Extra context for conversation |
| `suppressOutput` | boolean | Hide tool output from conversation |
---
## MCP Server Integration
Connect to MCP servers for pre-built tool capabilities.
### Remote HTTP Server
```typescript
const session = await client.createSession({
mcpServers: {
github: { type: "http", url: "https://api.githubcopilot.com/mcp/" },
},
});
```
### Local Stdio Server
```typescript
const session = await client.createSession({
mcpServers: {
filesystem: {
type: "local",
command: "npx",
args: ["-y", "@modelcontextprotocol/server-filesystem", "/allowed/path"],
tools: ["*"],
},
},
});
```
### MCP Config Fields
| Field | Type | Description |
|-------|------|-------------|
| `type` | `"local"` \| `"http"` | Server transport type |
| `command` | string | Executable path (local) |
| `args` | string[] | Command arguments (local) |
| `url` | string | Server URL (http) |
| `tools` | string[] | `["*"]` or specific tool names |
| `env` | object | Environment variables |
| `cwd` | string | Working directory (local) |
| `timeout` | number | Timeout in milliseconds |
---
## Authentication
### Methods (Priority Order)
1. **Explicit token**`githubToken` in constructor
2. **Environment variables**`COPILOT_GITHUB_TOKEN``GH_TOKEN``GITHUB_TOKEN`
3. **Stored OAuth** — From `copilot auth login`
4. **GitHub CLI**`gh auth` credentials
### Programmatic Token
```typescript
const client = new CopilotClient({ githubToken: process.env.GITHUB_TOKEN });
```
### BYOK (Bring Your Own Key)
Use your own API keys — no Copilot subscription required.
```typescript
const session = await client.createSession({
model: "gpt-5.2-codex",
provider: {
type: "openai",
baseUrl: "https://your-resource.openai.azure.com/openai/v1/",
wireApi: "responses",
apiKey: process.env.FOUNDRY_API_KEY,
},
});
```
| Provider | Type | Notes |
|----------|------|-------|
| OpenAI | `"openai"` | OpenAI API and compatible endpoints |
| Azure OpenAI | `"azure"` | Native Azure endpoints (don't include `/openai/v1`) |
| Azure AI Foundry | `"openai"` | OpenAI-compatible Foundry endpoints |
| Anthropic | `"anthropic"` | Claude models |
| Ollama | `"openai"` | Local models, no API key needed |
**Wire API:** Use `"responses"` for GPT-5 series, `"completions"` (default) for others.
---
## Session Persistence
Resume sessions across restarts by providing your own session ID.
```typescript
// Create with explicit ID
const session = await client.createSession({
sessionId: "user-123-task-456",
model: "gpt-4.1",
});
// Resume later
const resumed = await client.resumeSession("user-123-task-456");
await resumed.sendAndWait({ prompt: "What did we discuss?" });
```
**Session management:**
```typescript
const sessions = await client.listSessions(); // List all
await client.deleteSession("user-123-task-456"); // Delete
await session.destroy(); // Destroy active
```
**BYOK sessions:** Must re-provide `provider` config on resume (keys are not persisted).
### Infinite Sessions
For long-running workflows that may exceed context limits:
```typescript
const session = await client.createSession({
infiniteSessions: {
enabled: true,
backgroundCompactionThreshold: 0.80,
bufferExhaustionThreshold: 0.95,
},
});
```
---
## Custom Agents
Define specialized AI personas:
```typescript
const session = await client.createSession({
customAgents: [{
name: "pr-reviewer",
displayName: "PR Reviewer",
description: "Reviews pull requests for best practices",
prompt: "You are an expert code reviewer. Focus on security, performance, and maintainability.",
}],
});
```
---
## System Message
Control AI behavior and personality:
```typescript
const session = await client.createSession({
systemMessage: { content: "You are a helpful assistant. Always be concise." },
});
```
---
## Skills Integration
Load skill directories to extend Copilot's capabilities:
```typescript
const session = await client.createSession({
skillDirectories: ["./skills/code-review", "./skills/documentation"],
disabledSkills: ["experimental-feature"],
});
```
---
## Permission & Input Handlers
Handle tool permissions and user input requests programmatically:
```typescript
const session = await client.createSession({
onPermissionRequest: async (request) => {
// Auto-approve git commands only
if (request.kind === "shell") {
return { approved: request.command.startsWith("git") };
}
return { approved: true };
},
onUserInputRequest: async (request) => {
// Handle ask_user tool calls
return { response: "yes" };
},
});
```
---
## External CLI Server
Connect to a separately running CLI instead of auto-managing the process:
```bash
copilot --headless --port 4321
```
```typescript
const client = new CopilotClient({ cliUrl: "localhost:4321" });
```
---
## Client Configuration
| Option | Type | Description |
|--------|------|-------------|
| `cliPath` | string | Path to Copilot CLI executable |
| `cliUrl` | string | URL of external CLI server |
| `githubToken` | string | GitHub token for auth |
| `useLoggedInUser` | boolean | Use stored CLI credentials (default: true) |
| `logLevel` | string | `"none"` \| `"error"` \| `"warning"` \| `"info"` \| `"debug"` |
| `autoRestart` | boolean | Auto-restart CLI on crash (default: true) |
| `useStdio` | boolean | Use stdio transport (default: true) |
## Session Configuration
| Option | Type | Description |
|--------|------|-------------|
| `model` | string | Model to use (e.g., `"gpt-4.1"`) |
| `sessionId` | string | Custom ID for resumable sessions |
| `streaming` | boolean | Enable streaming responses |
| `tools` | Tool[] | Custom tools |
| `mcpServers` | object | MCP server configurations |
| `hooks` | object | Session hooks |
| `provider` | object | BYOK provider config |
| `customAgents` | object[] | Custom agent definitions |
| `systemMessage` | object | System message override |
| `skillDirectories` | string[] | Directories to load skills from |
| `disabledSkills` | string[] | Skills to disable |
| `reasoningEffort` | string | Reasoning effort level |
| `availableTools` | string[] | Restrict available tools |
| `excludedTools` | string[] | Exclude specific tools |
| `infiniteSessions` | object | Auto-compaction config |
| `workingDirectory` | string | Working directory |
---
## Debugging
Enable debug logging to troubleshoot issues:
```typescript
const client = new CopilotClient({ logLevel: "debug" });
```
**Common issues:**
- `CLI not found` → Install CLI or set `cliPath`
- `Not authenticated` → Run `copilot auth login` or provide `githubToken`
- `Session not found` → Don't use session after `destroy()`
- `Connection refused` → Check CLI process, enable `autoRestart`
---
## Key API Summary
| Language | Client | Session Create | Send | Stop |
|----------|--------|---------------|------|------|
| Node.js | `new CopilotClient()` | `client.createSession()` | `session.sendAndWait()` | `client.stop()` |
| Python | `CopilotClient()` | `client.create_session()` | `session.send_and_wait()` | `client.stop()` |
| Go | `copilot.NewClient(nil)` | `client.CreateSession()` | `session.SendAndWait()` | `client.Stop()` |

# Crypto BD Agent — Autonomous Business Development for Exchanges
> Production-tested patterns for building AI agents that autonomously discover,
> evaluate, and acquire token listings for cryptocurrency exchanges.
## Overview
This skill teaches AI agents systematic crypto business development: discover
promising tokens across chains, score them with a 100-point weighted system,
verify safety through wallet forensics, and manage outreach pipelines with
human-in-the-loop oversight.
Built from production experience running Buzz BD Agent by SolCex Exchange —
an autonomous agent on decentralized infrastructure with 13 intelligence
sources, x402 micropayments, and dual-chain ERC-8004 registration.
Reference implementation: https://github.com/buzzbysolcex/buzz-bd-agent
## When to Use This Skill
- Building an AI agent for crypto/DeFi business development
- Creating token evaluation and scoring systems
- Implementing multi-chain scanning pipelines
- Setting up autonomous payment workflows (x402)
- Designing wallet forensics for deployer analysis
- Managing BD pipelines with human-in-the-loop
- Registering agents on-chain via ERC-8004
- Implementing cost-efficient LLM cascades
## Do Not Use When
- Building trading bots (this is BD, not trading)
- Creating DeFi protocols or smart contracts
- Non-crypto business development
---
## Architecture
```text
Intelligence Sources (Free + Paid via x402)
|
v
Scoring Engine (100-point weighted)
|
v
Wallet Forensics (deployer verification)
|
v
Pipeline Manager (10-stage tracked)
|
v
Outreach Drafts → Human Approval → Send
```
### LLM Cascade Pattern
Route tasks to the cheapest model that handles them correctly:
```text
Fast/cheap model (routine: tweets, forum posts, pipeline updates)
↓ fallback on quality issues
Free API models (scanning, initial scoring, system tasks)
↓ fallback
Mid-tier model (outreach drafts, deeper analysis)
↓ fallback
Premium model (strategy, wallet forensics, final outreach)
```
Run a quality gate (10+ test cases) before promoting any new model.
---
## 1. Intelligence Gathering
### Free-First Principle
Always exhaust free data before paying. Target: $0/day for 90% of intelligence.
### Recommended Source Categories
| Category | What to Track | Example Sources |
|----------|--------------|-----------------|
| DEX Data | Prices, liquidity, pairs, chain coverage | DexScreener, GeckoTerminal |
| AI Momentum | Trending tokens, catalysts | AIXBT or similar trackers |
| Smart Money | VC follows, KOL accumulation | leak.me, Nansen free, Arkham |
| Contract Safety | Rug scores, LP lock, authorities | RugCheck |
| Wallet Forensics | Deployer analysis, fund flow | Helius (Solana), Allium (multi-chain) |
| Web Scraping | Project verification, team info | Firecrawl or similar |
| On-Chain Identity | Agent registration, trust signals | ATV Web3 Identity, ERC-8004 |
| Community | Forum signals, ecosystem intel | Protocol forums |
### Paid Sources (via x402 micropayments)
- Whale alert services (~$0.10/call, 1-2x daily)
- Breaking news aggregators (~$0.10/call, 2x daily)
- Budget: ~$0.30/day = ~$9/month
### Rules
1. Cross-reference: every prospect needs 2+ independent source confirmations
2. Multi-source cross-match gets +5 score bonus
3. Track ROI per paid source — did this call produce a qualified prospect?
4. Store insights in experience memory for continuous calibration
---
## 2. Token Scoring (100 Points)
### Base Criteria
| Factor | Weight | Scoring |
|--------|--------|---------|
| Liquidity | 25% | >$500K excellent, $200-500K good, $100K minimum |
| Market Cap | 20% | >$10M excellent, $1-10M good, $500K-1M acceptable |
| 24h Volume | 20% | >$1M excellent, $500K-1M good, $100-500K acceptable |
| Social Metrics | 15% | Multi-platform active, 2+ platforms, 1 platform |
| Token Age | 10% | Established >6mo, moderate 1-6mo, new <1mo |
| Team Transparency | 10% | Doxxed + active, partial, anonymous |
### Catalyst Adjustments
Positive: Hackathon win +10, mainnet launch +10, major partnership +10,
CEX listing +8, audit +8, multi-source match +5, whale signal +5,
wallet verified +3-5, cross-chain deployer +3, net positive wallet +2.
Negative: Rugpull association -15, exploit history -15, mixer funded AUTO REJECT,
contract vulnerability -10, serial creator -5, already on major CEXs -5,
team controversy -10, deployer dump >50% in 7 days -10 to -15.
### Score Actions
| Range | Action |
|-------|--------|
| 85-100 HOT | Immediate outreach + wallet forensics |
| 70-84 Qualified | Priority queue + wallet forensics |
| 50-69 Watch | Monitor 48 hours |
| 0-49 Skip | Log only, no action |
---
## 3. Wallet Forensics
Run on every token scoring 70+. This differentiates serious BD agents from
simple scanners.
### 5-Step Deployer Analysis
1. **Funded-By** — Where did deployer get funds? (exchange, mixer, other wallet)
2. **Balances** — Current holdings across chains
3. **Transfer History** — Dump patterns, accumulation, LP activity
4. **Identity** — ENS, social links, KYC indicators
5. **Score Adjustment** — Apply flags based on findings
### Wallet Flags
| Flag | Impact |
|------|--------|
| WALLET VERIFIED — clean, authorities revoked | +3 to +5 |
| INSTITUTIONAL — VC backing | +5 to +10 |
| NET POSITIVE — profitable wallet | +2 |
| SERIAL CREATOR — many tokens created | -5 |
| DUMP ALERT — >50% dump in 7 days | -10 to -15 |
| MIXER REJECT — tornado/mixer funded | AUTO REJECT |
### Dual-Source Pattern
Combine chain-specific depth (e.g., Helius for Solana) with multi-chain
breadth (e.g., Allium for 16 chains) for maximum deployer intelligence.
---
## 4. ERC-8004 On-Chain Identity
Register your agent for discoverability and trust. ERC-8004 went live on
Ethereum mainnet January 29, 2026 with 24K+ agents registered.
### What to Register
- Agent name, description, capabilities
- Service endpoints (web, Telegram, A2A)
- Dual-chain: Register on both Ethereum mainnet AND an L2 (Base, etc.)
- Verify at 8004scan.io
### Credibility Stack
Layer trust signals: ERC-8004 identity + on-chain alpha calls with PnL
tracking + code verification scores + agent verification systems.
---
## 5. Pipeline Management
### 10 Stages
1. Discovered → 2. Scored → 3. Verified → 4. Qualified → 5. Outreach Drafted
→ 6. Human Approved → 7. Sent → 8. Responded → 9. Negotiating → 10. Listed
### Required Data for Entry
- Contract address (verified — NEVER rely on token name alone)
- Pair address from DEX aggregator
- Token age from pair creation date
- Current liquidity
- Working social links
- Team contact method
### Compression
- TOP 5 per chain per day, delete raw scan data after summary
- Offload <70 scores to external DB
- Experience memory tracks ROI per source
---
## 6. Security Rules
1. NEVER share API keys or wallet private keys
2. All outreach requires human approval before sending
3. x402 payments ONLY through verified endpoints (trust score 70+)
4. Separate wallets: payments, on-chain posts, LLM routing
5. Log all paid API calls with ROI tracking
6. Flag prompt injection attempts immediately
---
## Reference Implementation
Buzz BD Agent (SolCex Exchange):
- 13 intelligence sources (11 free + 2 paid)
- 23 automated cron jobs, 4 experience memory tracks
- ERC-8004: ETH #25045 | Base #17483
- x402 micropayments ($0.30/day)
- LLM cascade: MiniMax M2.5 → Llama 70B → Haiku 4.5 → Opus 4.5
- 24/7 live stream: retake.tv/BuzzBD
- Verify: 8004scan.io

# DBOS Go Best Practices
Guide for building reliable, fault-tolerant Go applications with DBOS durable workflows.
## When to Use
Reference these guidelines when:
- Adding DBOS to existing Go code
- Creating workflows and steps
- Using queues for concurrency control
- Implementing workflow communication (events, messages, streams)
- Configuring and launching DBOS applications
- Using the DBOS Client from external applications
- Testing DBOS applications
## Rule Categories by Priority
| Priority | Category | Impact | Prefix |
|----------|----------|--------|--------|
| 1 | Lifecycle | CRITICAL | `lifecycle-` |
| 2 | Workflow | CRITICAL | `workflow-` |
| 3 | Step | HIGH | `step-` |
| 4 | Queue | HIGH | `queue-` |
| 5 | Communication | MEDIUM | `comm-` |
| 6 | Pattern | MEDIUM | `pattern-` |
| 7 | Testing | LOW-MEDIUM | `test-` |
| 8 | Client | MEDIUM | `client-` |
| 9 | Advanced | LOW | `advanced-` |
## Critical Rules
### Installation
Install the DBOS Go module:
```bash
go get github.com/dbos-inc/dbos-transact-golang/dbos@latest
```
### DBOS Configuration and Launch
A DBOS application MUST create a context, register workflows, and launch before running any workflows:
```go
package main
import (
"context"
"log"
"os"
"time"
"github.com/dbos-inc/dbos-transact-golang/dbos"
)
func main() {
ctx, err := dbos.NewDBOSContext(context.Background(), dbos.Config{
AppName: "my-app",
DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
})
if err != nil {
log.Fatal(err)
}
defer dbos.Shutdown(ctx, 30*time.Second)
dbos.RegisterWorkflow(ctx, myWorkflow)
if err := dbos.Launch(ctx); err != nil {
log.Fatal(err)
}
}
```
### Workflow and Step Structure
Workflows are comprised of steps. Any function performing complex operations or accessing external services must be run as a step using `dbos.RunAsStep`:
```go
func fetchData(ctx context.Context) (string, error) {
resp, err := http.Get("https://api.example.com/data")
if err != nil {
return "", err
}
defer resp.Body.Close()
body, _ := io.ReadAll(resp.Body)
return string(body), nil
}
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
result, err := dbos.RunAsStep(ctx, fetchData, dbos.WithStepName("fetchData"))
if err != nil {
return "", err
}
return result, nil
}
```
### Key Constraints
- Do NOT start or enqueue workflows from within steps
- Do NOT use uncontrolled goroutines to start workflows - use `dbos.RunWorkflow` with queues or `dbos.Go`/`dbos.Select` for concurrent steps
- Workflows MUST be deterministic - non-deterministic operations go in steps
- Do NOT modify global variables from workflows or steps
- All workflows and queues MUST be registered before calling `Launch()`
## How to Use
Read individual rule files for detailed explanations and examples:
```
references/lifecycle-config.md
references/workflow-determinism.md
references/queue-concurrency.md
```

title: Use Patching for Safe Workflow Upgrades
impact: LOW
impactDescription: Safely deploy breaking workflow changes without disrupting in-progress workflows
tags: advanced, patching, upgrade, breaking-change
---
## Use Patching for Safe Workflow Upgrades
Use `dbos.Patch` to safely deploy breaking changes to workflow code. Breaking changes alter which steps run or their order, which can cause recovery failures.
**Incorrect (breaking change without patching):**
```go
// BEFORE: original workflow
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
result, _ := dbos.RunAsStep(ctx, foo, dbos.WithStepName("foo"))
_, _ = dbos.RunAsStep(ctx, bar, dbos.WithStepName("bar"))
return result, nil
}
// AFTER: breaking change - recovery will fail for in-progress workflows!
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
result, _ := dbos.RunAsStep(ctx, baz, dbos.WithStepName("baz")) // Changed step
_, _ = dbos.RunAsStep(ctx, bar, dbos.WithStepName("bar"))
return result, nil
}
```
**Correct (using patch):**
```go
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
useBaz, err := dbos.Patch(ctx, "use-baz")
if err != nil {
return "", err
}
var result string
if useBaz {
result, _ = dbos.RunAsStep(ctx, baz, dbos.WithStepName("baz")) // New workflows
} else {
result, _ = dbos.RunAsStep(ctx, foo, dbos.WithStepName("foo")) // Old workflows
}
_, _ = dbos.RunAsStep(ctx, bar, dbos.WithStepName("bar"))
return result, nil
}
```
`dbos.Patch` returns `true` for new workflows and `false` for workflows that started before the patch.
**Deprecating patches (after all old workflows complete):**
```go
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
dbos.DeprecatePatch(ctx, "use-baz") // Always takes the new path
result, _ := dbos.RunAsStep(ctx, baz, dbos.WithStepName("baz"))
_, _ = dbos.RunAsStep(ctx, bar, dbos.WithStepName("bar"))
return result, nil
}
```
**Removing patches (after all workflows using DeprecatePatch complete):**
```go
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
result, _ := dbos.RunAsStep(ctx, baz, dbos.WithStepName("baz"))
_, _ = dbos.RunAsStep(ctx, bar, dbos.WithStepName("bar"))
return result, nil
}
```
Lifecycle: `Patch()` → deploy → wait for old workflows → `DeprecatePatch()` → deploy → wait → remove patch entirely.
**Required configuration** — patching must be explicitly enabled:
```go
ctx, _ := dbos.NewDBOSContext(context.Background(), dbos.Config{
AppName: "my-app",
DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
EnablePatching: true, // Required for dbos.Patch and dbos.DeprecatePatch
})
```
Without `EnablePatching: true`, calls to `dbos.Patch` and `dbos.DeprecatePatch` will fail.

title: Use Versioning for Blue-Green Deployments
impact: LOW
impactDescription: Enables safe deployment of new code versions alongside old ones
tags: advanced, versioning, blue-green, deployment
---
## Use Versioning for Blue-Green Deployments
Set `ApplicationVersion` in configuration to tag workflows with a version. DBOS only recovers workflows matching the current application version, preventing code mismatches during recovery.
**Incorrect (deploying new code that breaks in-progress workflows):**
```go
ctx, _ := dbos.NewDBOSContext(context.Background(), dbos.Config{
AppName: "my-app",
DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
// No version set - version auto-computed from binary hash
// Old workflows will be recovered with new code, which may break
})
```
**Correct (versioned deployment):**
```go
ctx, _ := dbos.NewDBOSContext(context.Background(), dbos.Config{
AppName: "my-app",
DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
ApplicationVersion: "2.0.0",
})
```
By default, the application version is automatically computed from a SHA-256 hash of the executable binary. Set it explicitly for more control.
**Blue-green deployment strategy:**
1. Deploy new version (v2) alongside old version (v1)
2. Direct new traffic to v2 processes
3. Let v1 processes "drain" (complete in-progress workflows)
4. Check for remaining v1 workflows:
```go
oldWorkflows, _ := dbos.ListWorkflows(ctx,
dbos.WithAppVersion("1.0.0"),
dbos.WithStatus([]dbos.WorkflowStatusType{dbos.WorkflowStatusPending}),
)
```
5. Once all v1 workflows are complete, retire v1 processes
**Fork to new version (for stuck workflows):**
```go
// Fork a workflow from a failed step to run on the new version
handle, _ := dbos.ForkWorkflow[string](ctx, dbos.ForkWorkflowInput{
OriginalWorkflowID: workflowID,
StartStep: failedStepID,
ApplicationVersion: "2.0.0",
})

title: Enqueue Workflows from External Applications
impact: HIGH
impactDescription: Enables external services to submit work to DBOS queues
tags: client, enqueue, external, queue
---
## Enqueue Workflows from External Applications
Use `client.Enqueue()` to submit workflows from outside your DBOS application. Since the Client runs externally, workflow and queue metadata must be specified explicitly by name.
**Incorrect (trying to use RunWorkflow from external code):**
```go
// RunWorkflow requires a full DBOS context with registered workflows
dbos.RunWorkflow(ctx, processTask, "data", dbos.WithQueue("myQueue"))
```
**Correct (using Client.Enqueue):**
```go
client, err := dbos.NewClient(context.Background(), dbos.ClientConfig{
DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
})
if err != nil {
log.Fatal(err)
}
defer client.Shutdown(10 * time.Second)
// Basic enqueue - specify workflow and queue by name
handle, err := client.Enqueue("task_queue", "processTask", "task-data")
if err != nil {
log.Fatal(err)
}
// Wait for the result
result, err := handle.GetResult()
```
**Enqueue with options:**
```go
handle, err := client.Enqueue("task_queue", "processTask", "task-data",
dbos.WithEnqueueWorkflowID("custom-id"),
dbos.WithEnqueueDeduplicationID("unique-id"),
dbos.WithEnqueuePriority(10),
dbos.WithEnqueueTimeout(5*time.Minute),
dbos.WithEnqueueQueuePartitionKey("user-123"),
dbos.WithEnqueueApplicationVersion("2.0.0"),
)
```
Enqueue options:
- `WithEnqueueWorkflowID`: Custom workflow ID
- `WithEnqueueDeduplicationID`: Prevent duplicate enqueues
- `WithEnqueuePriority`: Queue priority (lower = higher priority)
- `WithEnqueueTimeout`: Workflow timeout
- `WithEnqueueQueuePartitionKey`: Partition key for partitioned queues
- `WithEnqueueApplicationVersion`: Override application version
The workflow name must match the registered name or custom name set with `WithWorkflowName` during registration.
Always call `client.Shutdown()` when done.

title: Initialize Client for External Access
impact: HIGH
impactDescription: Enables external applications to interact with DBOS workflows
tags: client, external, setup, initialization
---
## Initialize Client for External Access
Use `dbos.NewClient` to interact with DBOS from external applications like API servers, CLI tools, or separate services. The Client connects directly to the DBOS system database.
**Incorrect (using full DBOS context from an external app):**
```go
// Full DBOS context requires Launch() - too heavy for external clients
ctx, _ := dbos.NewDBOSContext(context.Background(), config)
dbos.Launch(ctx)
```
**Correct (using Client):**
```go
client, err := dbos.NewClient(context.Background(), dbos.ClientConfig{
DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
})
if err != nil {
log.Fatal(err)
}
defer client.Shutdown(10 * time.Second)
// Send a message to a workflow
err = client.Send(workflowID, "notification", "topic")
// Get an event from a workflow
event, err := client.GetEvent(workflowID, "status", 60*time.Second)
// Retrieve a workflow handle
handle, err := client.RetrieveWorkflow(workflowID)
result, err := handle.GetResult()
// List workflows
workflows, err := client.ListWorkflows(
dbos.WithStatus([]dbos.WorkflowStatusType{dbos.WorkflowStatusError}),
)
// Workflow management
err = client.CancelWorkflow(workflowID)
handle, err = client.ResumeWorkflow(workflowID)
// Read a stream
values, closed, err := client.ClientReadStream(workflowID, "results")
// Read a stream asynchronously
ch, err := client.ClientReadStreamAsync(workflowID, "results")
```
ClientConfig options:
- `DatabaseURL` (required unless `SystemDBPool` is set): PostgreSQL connection string
- `SystemDBPool`: Custom `*pgxpool.Pool`
- `DatabaseSchema`: Schema name (default: `"dbos"`)
- `Logger`: Custom `*slog.Logger`
Always call `client.Shutdown()` when done.

title: Use Events for Workflow Status Publishing
impact: MEDIUM
impactDescription: Enables real-time progress monitoring and interactive workflows
tags: communication, events, status, key-value
---
## Use Events for Workflow Status Publishing
Workflows can publish events (key-value pairs) with `dbos.SetEvent`. Other code can read events with `dbos.GetEvent`. Events are persisted and useful for real-time progress monitoring.
**Incorrect (using external state for progress):**
```go
var progress int // Global variable - not durable!
func processData(ctx dbos.DBOSContext, input string) (string, error) {
progress = 50 // Not persisted, lost on restart
return input, nil
}
```
**Correct (using events):**
```go
func processData(ctx dbos.DBOSContext, input string) (string, error) {
dbos.SetEvent(ctx, "status", "processing")
_, err := dbos.RunAsStep(ctx, stepOne, dbos.WithStepName("stepOne"))
if err != nil {
return "", err
}
dbos.SetEvent(ctx, "progress", 50)
_, err = dbos.RunAsStep(ctx, stepTwo, dbos.WithStepName("stepTwo"))
if err != nil {
return "", err
}
dbos.SetEvent(ctx, "progress", 100)
dbos.SetEvent(ctx, "status", "complete")
return "done", nil
}
// Read events from outside the workflow
status, err := dbos.GetEvent[string](ctx, workflowID, "status", 60*time.Second)
progress, err := dbos.GetEvent[int](ctx, workflowID, "progress", 60*time.Second)
```
Events are useful for interactive workflows. For example, a checkout workflow can publish a payment URL for the caller to redirect to:
```go
func checkoutWorkflow(ctx dbos.DBOSContext, order Order) (string, error) {
paymentURL, err := dbos.RunAsStep(ctx, func(ctx context.Context) (string, error) {
return createPayment(order)
}, dbos.WithStepName("createPayment"))
if err != nil {
return "", err
}
dbos.SetEvent(ctx, "paymentURL", paymentURL)
// Continue processing...
return "success", nil
}
// HTTP handler starts workflow and reads the payment URL
handle, _ := dbos.RunWorkflow(ctx, checkoutWorkflow, order)
url, _ := dbos.GetEvent[string](ctx, handle.GetWorkflowID(), "paymentURL", 300*time.Second)
```
`GetEvent` blocks until the event is set or the timeout expires. It returns the zero value of the type if the timeout is reached.

title: Use Messages for Workflow Notifications
impact: MEDIUM
impactDescription: Enables reliable inter-workflow and external-to-workflow communication
tags: communication, messages, send, recv, notification
---
## Use Messages for Workflow Notifications
Use `dbos.Send` to send messages to a workflow and `dbos.Recv` to receive them. Messages are queued per topic and persisted for reliable delivery.
**Incorrect (using external messaging for workflow communication):**
```go
// External message queue is not integrated with workflow recovery
ch := make(chan string) // Not durable!
```
**Correct (using DBOS messages):**
```go
func checkoutWorkflow(ctx dbos.DBOSContext, orderID string) (string, error) {
// Wait for payment notification (timeout 120 seconds)
notification, err := dbos.Recv[string](ctx, "payment_status", 120*time.Second)
if err != nil {
return "", err
}
if notification == "paid" {
_, err = dbos.RunAsStep(ctx, func(ctx context.Context) (string, error) {
return fulfillOrder(orderID)
}, dbos.WithStepName("fulfillOrder"))
return "fulfilled", err
}
_, err = dbos.RunAsStep(ctx, func(ctx context.Context) (string, error) {
return cancelOrder(orderID)
}, dbos.WithStepName("cancelOrder"))
return "cancelled", err
}
// Send a message from a webhook handler
func paymentWebhook(ctx dbos.DBOSContext, workflowID, status string) error {
return dbos.Send(ctx, workflowID, status, "payment_status")
}
```
Key behaviors:
- `Recv` waits for and consumes the next message for the specified topic
- Returns the zero value if the wait times out, with a `DBOSError` with code `TimeoutError`
- Messages without a topic can only be received by `Recv` without a topic
- Messages are queued per-topic (FIFO)
**Reliability guarantees:**
- All messages are persisted to the database
- Messages sent from workflows are delivered exactly-once

tags: communication, stream, real-time, channel
---
## Use Streams for Real-Time Data
Workflows can stream data to clients in real-time using `dbos.WriteStream`, `dbos.CloseStream`, and `dbos.ReadStream`/`dbos.ReadStreamAsync`. Useful for LLM output streaming or progress reporting.
**Incorrect (accumulating results then returning at end):**
```go

}
// Read the stream synchronously (blocks until closed)
handle, _ := dbos.RunWorkflow(ctx, processWorkflow, items)
values, closed, err := dbos.ReadStream[string](ctx, handle.GetWorkflowID(), "results")
```
**Async stream reading with channels:**
```go

if err != nil {
log.Fatal(err)
}
for sv := range ch {
if sv.Err != nil {
log.Fatal(sv.Err)
}
if sv.Closed {
break
}
fmt.Println("Received:", sv.Value)
}
```
Key behaviors:
- A workflow may have any number of streams, each identified by a unique key
- Streams are immutable and append-only
- Writes from workflows happen exactly-once
- Streams are automatically closed when the workflow terminates
- `ReadStream` blocks until the workflow is inactive or the stream is closed
- `ReadStreamAsync` returns a channel of `StreamValue[R]` for non-blocking reads

## Configure and Launch DBOS Properly
Every DBOS application must create a context, register workflows and queues, then launch before running any workflows.
**Incorrect (missing configuration or launch):**
```go
// No context or launch!
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
return input, nil
}
func main() {
// This will fail - DBOS is not initialized or launched
dbos.RegisterWorkflow(nil, myWorkflow) // panic: ctx cannot be nil
}
```
**Correct (create context, register, launch):**
```go
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
return input, nil
}
func main() {
ctx, err := dbos.NewDBOSContext(context.Background(), dbos.Config{
AppName: "my-app",
DatabaseURL: os.Getenv("DBOS_SYSTEM_DATABASE_URL"),
})
if err != nil {
log.Fatal(err)
}
defer dbos.Shutdown(ctx, 30*time.Second)
dbos.RegisterWorkflow(ctx, myWorkflow)
if err := dbos.Launch(ctx); err != nil {
log.Fatal(err)
}
handle, err := dbos.RunWorkflow(ctx, myWorkflow, "hello")
if err != nil {
log.Fatal(err)
}
result, err := handle.GetResult()
fmt.Println(result) // "hello"
}
```
Config fields:
- `AppName` (required): Application identifier
- `DatabaseURL` (required unless `SystemDBPool` is set): PostgreSQL connection string
- `SystemDBPool`: Custom `*pgxpool.Pool` (takes precedence over `DatabaseURL`)
- `DatabaseSchema`: Schema name (default: `"dbos"`)
- `Logger`: Custom `*slog.Logger` (defaults to stdout)
- `AdminServer`: Enable HTTP admin server (default: `false`)
- `AdminServerPort`: Admin server port (default: `3001`)
- `ApplicationVersion`: App version (auto-computed from binary hash if not set)
- `ExecutorID`: Executor identifier (default: `"local"`)

title: Debounce Workflows to Prevent Wasted Work
impact: MEDIUM
impactDescription: Prevents redundant workflow executions during rapid triggers
tags: pattern, debounce, delay, efficiency
---
## Debounce Workflows to Prevent Wasted Work
Use `dbos.NewDebouncer` to delay workflow execution until some time has passed since the last trigger. This prevents wasted work when a workflow is triggered multiple times in quick succession.
**Incorrect (executing on every trigger):**
```go
// Every keystroke triggers a new workflow - wasteful!
func onInputChange(ctx dbos.DBOSContext, userInput string) {
dbos.RunWorkflow(ctx, processInput, userInput)
}
```
**Correct (using Debouncer):**
```go
// Create debouncer before Launch()
debouncer := dbos.NewDebouncer(ctx, processInput,
dbos.WithDebouncerTimeout(120*time.Second), // Max wait: 2 minutes
)
func onInputChange(ctx dbos.DBOSContext, userID, userInput string) error {
// Delays execution by 60 seconds from the last call
// Uses the LAST set of inputs when finally executing
_, err := debouncer.Debounce(ctx, userID, 60*time.Second, userInput)
return err
}
```
Key behaviors:
- First argument to `Debounce` is the debounce key, grouping executions together (e.g., per user)
- Second argument is the delay duration from the last call
- `WithDebouncerTimeout` sets a max wait time since the first trigger
- When the workflow finally executes, it uses the **last** set of inputs
- After execution begins, the next `Debounce` call starts a new cycle
- Debouncers must be created **before** `Launch()`
Type signature: `Debouncer[P any, R any]` — the type parameters match the target workflow.

## Use Workflow IDs for Idempotency
Assign a workflow ID to ensure a workflow executes only once, even if called multiple times. This prevents duplicate side effects like double payments.
**Incorrect (no idempotency):**
```go
func processPayment(ctx dbos.DBOSContext, orderID string) (string, error) {
_, err := dbos.RunAsStep(ctx, func(ctx context.Context) (string, error) {
return chargeCard(orderID)
}, dbos.WithStepName("chargeCard"))
return "charged", err
}
// Multiple calls could charge the card multiple times!
dbos.RunWorkflow(ctx, processPayment, "order-123")
dbos.RunWorkflow(ctx, processPayment, "order-123") // Double charge!
```
**Correct (with workflow ID):**
```go
func processPayment(ctx dbos.DBOSContext, orderID string) (string, error) {
_, err := dbos.RunAsStep(ctx, func(ctx context.Context) (string, error) {
return chargeCard(orderID)
}, dbos.WithStepName("chargeCard"))
return "charged", err
}
// Same workflow ID = only one execution
workflowID := fmt.Sprintf("payment-%s", orderID)
dbos.RunWorkflow(ctx, processPayment, "order-123",
dbos.WithWorkflowID(workflowID),
)
dbos.RunWorkflow(ctx, processPayment, "order-123",
dbos.WithWorkflowID(workflowID),
)
// Second call returns the result of the first execution
```
Access the current workflow ID inside a workflow:
```go
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
currentID, err := dbos.GetWorkflowID(ctx)
if err != nil {
return "", err
}
fmt.Printf("Running workflow: %s\n", currentID)
return input, nil
}
```
Workflow IDs must be **globally unique** for your application. If not set, a random UUID is generated.

## Create Scheduled Workflows
Use `dbos.WithSchedule` when registering a workflow to run it on a cron schedule. Each scheduled invocation runs exactly once per interval.
**Incorrect (manual scheduling with goroutine):**
```go
// Manual scheduling is not durable and misses intervals during downtime
go func() {
for {
generateReport()
time.Sleep(60 * time.Second)

```go
// Scheduled workflow must accept time.Time as input
func everyThirtySeconds(ctx dbos.DBOSContext, scheduledTime time.Time) (string, error) {
fmt.Println("Running scheduled task at:", scheduledTime)
return "done", nil
}
func dailyReport(ctx dbos.DBOSContext, scheduledTime time.Time) (string, error) {
_, err := dbos.RunAsStep(ctx, func(ctx context.Context) (string, error) {
return generateReport()
}, dbos.WithStepName("generateReport"))
return "report generated", err
}
func main() {
ctx, _ := dbos.NewDBOSContext(context.Background(), config)
defer dbos.Shutdown(ctx, 30*time.Second)
dbos.RegisterWorkflow(ctx, everyThirtySeconds,
dbos.WithSchedule("*/30 * * * * *"),
)
dbos.RegisterWorkflow(ctx, dailyReport,
dbos.WithSchedule("0 0 9 * * *"), // 9 AM daily
)
dbos.Launch(ctx)
select {} // Block forever
}
```
Scheduled workflows must accept exactly one parameter of type `time.Time` representing the scheduled execution time.
DBOS crontab uses 6 fields with second precision:
```text
┌────────────── second

title: Use Durable Sleep for Delayed Execution

tags: pattern, sleep, delay, durable, schedule
---
## Use Durable Sleep for Delayed Execution
Use `dbos.Sleep` for durable delays within workflows. The wakeup time is stored in the database, so the sleep survives restarts.
**Incorrect (non-durable sleep):**
```go
func delayedTask(ctx dbos.DBOSContext, input string) (string, error) {
// time.Sleep is not durable - lost on restart!
time.Sleep(60 * time.Second)
result, err := dbos.RunAsStep(ctx, doWork, dbos.WithStepName("doWork"))
return result, err
}
```
**Correct (durable sleep):**
```go
func delayedTask(ctx dbos.DBOSContext, input string) (string, error) {
// Durable sleep - survives restarts
_, err := dbos.Sleep(ctx, 60*time.Second)
if err != nil {
return "", err
}
result, err := dbos.RunAsStep(ctx, doWork, dbos.WithStepName("doWork"))
return result, err
}
```
`dbos.Sleep` takes a `time.Duration`. It returns the remaining sleep duration (zero if completed normally).
Use cases:
- Scheduling tasks to run in the future
- Implementing retry delays
- Delays spanning hours, days, or weeks
```go
func scheduledTask(ctx dbos.DBOSContext, task string) (string, error) {
// Sleep for one week
dbos.Sleep(ctx, 7*24*time.Hour)
return processTask(task)
}

## Use Queues for Concurrent Workflows
Queues run many workflows concurrently with managed flow control. Use them when you need to control how many workflows run at once.
**Incorrect (uncontrolled concurrency):**
```go
// Starting many workflows without control - could overwhelm resources
for _, task := range tasks {
dbos.RunWorkflow(ctx, processTask, task)

func processAllTasks(ctx dbos.DBOSContext, tasks []string) ([]string, error) {
var handles []dbos.WorkflowHandle[string]
for _, task := range tasks {
handle, err := dbos.RunWorkflow(ctx, processTask, task,
dbos.WithQueue(queue.Name),
)
if err != nil {
return nil, err
}
handles = append(handles, handle)
}
// Wait for all tasks
var results []string
for _, h := range handles {
result, err := h.GetResult()
if err != nil {
return nil, err
}
results = append(results, result)
}
return results, nil
}
```
Queues process workflows in FIFO order. All queues must be created with `dbos.NewWorkflowQueue` before `Launch()`.

## Control Queue Concurrency
Queues support worker-level and global concurrency limits to prevent resource exhaustion.
**Incorrect (no concurrency control):**
```go
queue := dbos.NewWorkflowQueue(ctx, "heavy_tasks") // No limits - could exhaust memory
```
**Correct (worker concurrency):**
```go
// Each process runs at most 5 tasks from this queue
queue := dbos.NewWorkflowQueue(ctx, "heavy_tasks",
dbos.WithWorkerConcurrency(5),
)
```
**Correct (global concurrency):**
```go
// At most 10 tasks run across ALL processes
queue := dbos.NewWorkflowQueue(ctx, "limited_tasks",
dbos.WithGlobalConcurrency(10),
)
```
**In-order processing (sequential):**
```go
// Only one task at a time - guarantees order
serialQueue := dbos.NewWorkflowQueue(ctx, "sequential_queue",
dbos.WithGlobalConcurrency(1),
)
```
Worker concurrency is recommended for most use cases. Take care with global concurrency as any `PENDING` workflow on the queue counts toward the limit, including workflows from previous application versions.
When using worker concurrency, each process must have a unique `ExecutorID` set in configuration (this is automatic with DBOS Conductor or Cloud).

## Deduplicate Queued Workflows
Set a deduplication ID when enqueuing to prevent duplicate workflow executions. If a workflow with the same deduplication ID is already enqueued or executing, a `DBOSError` with code `QueueDeduplicated` is returned.
**Incorrect (no deduplication):**
```go
// Multiple calls could enqueue duplicates
func handleClick(ctx dbos.DBOSContext, userID, task string) error {
_, err := dbos.RunWorkflow(ctx, processTask, task,
dbos.WithQueue(queue.Name),
)
return err
}
```
**Correct (with deduplication):**
```go
func handleClick(ctx dbos.DBOSContext, userID, task string) error {
_, err := dbos.RunWorkflow(ctx, processTask, task,
dbos.WithQueue(queue.Name),
dbos.WithDeduplicationID(userID),
)
if err != nil {
// Check if it was deduplicated
var dbosErr *dbos.DBOSError
if errors.As(err, &dbosErr) && dbosErr.Code == dbos.QueueDeduplicated {
fmt.Println("Task already in progress for user:", userID)
return nil
}
return err
}
return nil
}
```
Deduplication is per-queue. The deduplication ID is active while the workflow has status `ENQUEUED` or `PENDING`. Once the workflow completes, a new workflow with the same deduplication ID can be enqueued.
This is useful for:
- Ensuring one active task per user
- Preventing duplicate form submissions
- Idempotent event processing

## Control Which Queues a Worker Listens To
Use `ListenQueues` to make a process only dequeue from specific queues. This enables heterogeneous worker pools.
**Incorrect (all workers process all queues):**
```go
cpuQueue := dbos.NewWorkflowQueue(ctx, "cpu_queue")
gpuQueue := dbos.NewWorkflowQueue(ctx, "gpu_queue")
// Every worker processes both CPU and GPU tasks
// GPU tasks on CPU workers will fail or be slow!
dbos.Launch(ctx)

**Correct (selective queue listening):**
```go
cpuQueue := dbos.NewWorkflowQueue(ctx, "cpu_queue")
gpuQueue := dbos.NewWorkflowQueue(ctx, "gpu_queue")
workerType := os.Getenv("WORKER_TYPE") // "cpu" or "gpu"

ctx.ListenQueues(ctx, gpuQueue)
} else if workerType == "cpu" {

`ListenQueues` only controls dequeuing. A CPU worker can still enqueue tasks onto the GPU queue:

dbos.RunWorkflow(ctx, gpuTask, "data",
dbos.WithQueue(gpuQueue.Name),

## Use Steps for External Operations
Any function that performs complex operations, accesses external APIs, or has side effects should be a step. Step results are checkpointed, enabling workflow recovery.

// External API call directly in workflow - not checkpointed!
resp, err := http.Get("https://api.example.com/data")
if err != nil {
return "", err
}
defer resp.Body.Close()
body, _ := io.ReadAll(resp.Body)
return string(body), nil
}
```
**Correct (external call in step using `dbos.RunAsStep`):**
```go
func fetchData(ctx context.Context) (string, error) {
resp, err := http.Get("https://api.example.com/data")
if err != nil {
return "", err
}
defer resp.Body.Close()
body, _ := io.ReadAll(resp.Body)
return string(body), nil
}
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
data, err := dbos.RunAsStep(ctx, fetchData, dbos.WithStepName("fetchData"))
if err != nil {
return "", err
}
return data, nil
}
```
`dbos.RunAsStep` can also accept an inline closure:
```go
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
data, err := dbos.RunAsStep(ctx, func(ctx context.Context) (string, error) {
resp, err := http.Get("https://api.example.com/data")
if err != nil {
return "", err
}
defer resp.Body.Close()
body, _ := io.ReadAll(resp.Body)
return string(body), nil
}, dbos.WithStepName("fetchData"))
return data, err
}
```
Step type signature: `type Step[R any] func(ctx context.Context) (R, error)`
Step requirements:
- The function must accept a `context.Context` parameter — use the one provided, not the workflow's context
- Inputs and outputs must be serializable to JSON
- Cannot start or enqueue workflows from within steps
- Calling a step from within another step makes the inner call part of the outer step's execution
When to use steps:
- API calls to external services
- File system operations
- Random number generation
- Getting current time
- Any non-deterministic operation

## Run Concurrent Steps with Go and Select
Use `dbos.Go` to run steps concurrently in goroutines and `dbos.Select` to durably select the first completed result. Both operations are checkpointed for recovery.
**Incorrect (raw goroutines without checkpointing):**
```go
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
// Raw goroutines are not checkpointed - recovery breaks!
ch := make(chan string, 2)
go func() { ch <- callAPI1() }()
go func() { ch <- callAPI2() }()
return <-ch, nil
}
```
**Correct (using dbos.Go for concurrent steps):**
```go
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
// Start steps concurrently
ch1, err := dbos.Go(ctx, func(ctx context.Context) (string, error) {
return callAPI1(ctx)
}, dbos.WithStepName("api1"))
if err != nil {
return "", err
}
ch2, err := dbos.Go(ctx, func(ctx context.Context) (string, error) {
return callAPI2(ctx)
}, dbos.WithStepName("api2"))
if err != nil {
return "", err
}
// Wait for the first result (durable select)
result, err := dbos.Select(ctx, []<-chan dbos.StepOutcome[string]{ch1, ch2})
if err != nil {
return "", err
}
return result, nil
}
```
**Waiting for all concurrent steps:**
```go
func myWorkflow(ctx dbos.DBOSContext, input string) ([]string, error) {
ch1, _ := dbos.Go(ctx, step1, dbos.WithStepName("step1"))
ch2, _ := dbos.Go(ctx, step2, dbos.WithStepName("step2"))
ch3, _ := dbos.Go(ctx, step3, dbos.WithStepName("step3"))
// Collect all results
results := make([]string, 3)
for i, ch := range []<-chan dbos.StepOutcome[string]{ch1, ch2, ch3} {
outcome := <-ch
if outcome.Err != nil {
return nil, outcome.Err
}
results[i] = outcome.Result
}
return results, nil
}
```
Key behaviors:
- `dbos.Go` starts a step in a goroutine and returns a channel of `StepOutcome[R]`
- `dbos.Select` durably selects the first completed result and checkpoints which channel was selected
- On recovery, `Select` replays the same selection, maintaining determinism
- Steps started with `Go` follow the same retry and checkpointing rules as `RunAsStep`

dbos.WithBaseInterval(500*time.Millisecond),
dbos.WithBackoffFactor(2.0),
dbos.WithMaxInterval(5*time.Second),
)
return data, err
}
```
Retry parameters:
- `WithStepMaxRetries(n)`: Maximum retry attempts (default: `0` — no retries)
- `WithBaseInterval(d)`: Initial delay between retries (default: `100ms`)
- `WithBackoffFactor(f)`: Multiplier for exponential backoff (default: `2.0`)
- `WithMaxInterval(d)`: Maximum delay between retries (default: `5s`)
With defaults, retry delays are: 100ms, 200ms, 400ms, 800ms, 1.6s, 3.2s, 5s, 5s...
If all retries are exhausted, a `DBOSError` with code `MaxStepRetriesExceeded` is returned to the calling workflow.

title: Use Proper Test Setup for DBOS
impact: LOW-MEDIUM
impactDescription: Ensures consistent test results with proper DBOS lifecycle management
tags: testing, go-test, setup, integration, mock
---
## Use Proper Test Setup for DBOS
DBOS applications can be tested with unit tests (mocking DBOSContext) or integration tests (real Postgres database).
**Incorrect (no lifecycle management between tests):**
```go
// Tests share state - results are inconsistent!
func TestOne(t *testing.T) {
myWorkflow(ctx, "input")
}
func TestTwo(t *testing.T) {
// Previous test's state leaks into this test
myWorkflow(ctx, "input")
}
```
**Correct (unit testing with mocks):**
The `DBOSContext` interface is fully mockable. Use a mocking library like `testify/mock` or `mockery`:
```go
func TestWorkflow(t *testing.T) {
mockCtx := mocks.NewMockDBOSContext(t)
// Mock RunAsStep to return a canned value
mockCtx.On("RunAsStep", mockCtx, mock.Anything, mock.Anything).
Return("mock-result", nil)
result, err := myWorkflow(mockCtx, "input")
assert.NoError(t, err)
assert.Equal(t, "expected", result)
mockCtx.AssertExpectations(t)
}
```
**Correct (integration testing with Postgres):**
```go
func setupDBOS(t *testing.T) dbos.DBOSContext {
t.Helper()
databaseURL := os.Getenv("DBOS_TEST_DATABASE_URL")
if databaseURL == "" {
t.Skip("DBOS_TEST_DATABASE_URL not set")
}
ctx, err := dbos.NewDBOSContext(context.Background(), dbos.Config{
AppName: "test-" + t.Name(),
DatabaseURL: databaseURL,
})
require.NoError(t, err)
dbos.RegisterWorkflow(ctx, myWorkflow)
err = dbos.Launch(ctx)
require.NoError(t, err)
t.Cleanup(func() {
dbos.Shutdown(ctx, 10*time.Second)
})
return ctx
}
func TestWorkflowIntegration(t *testing.T) {
ctx := setupDBOS(t)
handle, err := dbos.RunWorkflow(ctx, myWorkflow, "test-input")
require.NoError(t, err)
result, err := handle.GetResult()
require.NoError(t, err)
assert.Equal(t, "expected-output", result)
}
```
Key points:
- Use `t.Cleanup` to ensure `Shutdown` is called after each test
- Use unique `AppName` per test to avoid collisions
- Mock `DBOSContext` for fast unit tests without Postgres
- Use real Postgres for integration tests that verify durable behavior

title: Start Workflows in Background

impactDescription: Background workflows enable reliable async processing
tags: workflow, background, handle, async
---
## Start Workflows in Background
Use `dbos.RunWorkflow` to start a workflow and get a handle to track it. The workflow is guaranteed to run to completion even if the app is interrupted.
**Incorrect (no way to track background work):**
```go
func processData(ctx dbos.DBOSContext, data string) (string, error) {
// ...
return "processed: " + data, nil
}
// Fire and forget in a goroutine - no durability, no tracking
go func() {
processData(ctx, data)
}()
```
**Correct (using RunWorkflow):**
```go
func processData(ctx dbos.DBOSContext, data string) (string, error) {
return "processed: " + data, nil
}
func main() {
// ... setup and launch ...
// Start workflow, get handle
handle, err := dbos.RunWorkflow(ctx, processData, "input")
if err != nil {
log.Fatal(err)
}
// Get the workflow ID
fmt.Println(handle.GetWorkflowID())
// Wait for result
result, err := handle.GetResult()
// Check status
status, err := handle.GetStatus()
}
```
Retrieve a handle later by workflow ID:
```go
handle, err := dbos.RetrieveWorkflow[string](ctx, workflowID)
result, err := handle.GetResult()
```
`GetResult` supports options:
- `dbos.WithHandleTimeout(timeout)`: Return a timeout error if the workflow doesn't complete within the duration
- `dbos.WithHandlePollingInterval(interval)`: Control how often the database is polled for completion

title: Follow Workflow Constraints

impactDescription: Violating constraints breaks recovery and durability guarantees
tags: workflow, constraints, rules, best-practices
---
## Follow Workflow Constraints
Workflows have specific constraints to maintain durability guarantees. Violating them can break recovery.
**Incorrect (starting workflows from steps):**
```go
func myStep(ctx context.Context) (string, error) {
// Don't start workflows from steps!
// The step's context.Context does not support workflow operations
return "", nil
}
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
// Starting a child workflow inside a step breaks determinism
dbos.RunAsStep(ctx, func(ctx context.Context) (string, error) {
handle, _ := dbos.RunWorkflow(ctx.(dbos.DBOSContext), otherWorkflow, "data") // WRONG
return handle.GetWorkflowID(), nil
})
return "", nil
}
```
**Correct (workflow operations only from workflows):**
```go
func fetchData(ctx context.Context) (string, error) {
// Steps only do external operations
resp, err := http.Get("https://api.example.com")
if err != nil {
return "", err
}
defer resp.Body.Close()
body, _ := io.ReadAll(resp.Body)
return string(body), nil
}
func myWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
data, err := dbos.RunAsStep(ctx, fetchData, dbos.WithStepName("fetchData"))
if err != nil {
return "", err
}
// Start child workflows from the parent workflow
handle, err := dbos.RunWorkflow(ctx, otherWorkflow, data)
if err != nil {
return "", err
}
// Receive messages from the workflow
msg, err := dbos.Recv[string](ctx, "topic", 60*time.Second)
// Set events from the workflow
dbos.SetEvent(ctx, "status", "done")
return data, nil
}
```
Additional constraints:
- Don't modify global variables from workflows or steps
- All workflows and queues must be registered **before** `Launch()`
- Concurrent steps must start in deterministic order using `dbos.Go`/`dbos.Select`

title: Cancel, Resume, and Fork Workflows
impact: MEDIUM
impactDescription: Enables operational control over long-running workflows
tags: workflow, cancel, resume, fork, management
---
## Cancel, Resume, and Fork Workflows
DBOS provides functions to cancel, resume, and fork workflows for operational control.
**Incorrect (no way to handle stuck or failed workflows):**
```go
// Workflow is stuck or failed - no recovery mechanism
handle, _ := dbos.RunWorkflow(ctx, processTask, "data")
// If the workflow fails, there's no way to retry or recover
```
**Correct (using cancel, resume, and fork):**
```go
// Cancel a workflow - stops at its next step
err := dbos.CancelWorkflow(ctx, workflowID)
// Resume from the last completed step
handle, err := dbos.ResumeWorkflow[string](ctx, workflowID)
result, err := handle.GetResult()
```
Cancellation sets the workflow status to `CANCELLED` and preempts execution at the beginning of the next step. Cancelling also cancels all child workflows.
Resume restarts a workflow from its last completed step. Use this for workflows that are cancelled or have exceeded their maximum recovery attempts. You can also use this to start an enqueued workflow immediately, bypassing its queue.
Fork a workflow from a specific step:
```go
// List steps to find the right step ID
steps, err := dbos.GetWorkflowSteps(ctx, workflowID)
// Fork from a specific step
forkHandle, err := dbos.ForkWorkflow[string](ctx, dbos.ForkWorkflowInput{
OriginalWorkflowID: workflowID,
StartStep: 2, // Fork from step 2
ForkedWorkflowID: "new-wf-id", // Optional
ApplicationVersion: "2.0.0", // Optional
})
result, err := forkHandle.GetResult()
```
Forking creates a new workflow with a new ID, copying the original workflow's inputs and step outputs up to the selected step.

title: Keep Workflows Deterministic

impactDescription: Non-deterministic workflows cannot recover correctly
tags: workflow, determinism, recovery, reliability
---
## Keep Workflows Deterministic
Workflow functions must be deterministic: given the same inputs and step return values, they must invoke the same steps in the same order. Non-deterministic operations must be moved to steps.
**Incorrect (non-deterministic workflow):**
```go
func exampleWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
// Random value in workflow breaks recovery!
// On replay, rand.Intn returns a different value,
// so the workflow may take a different branch.
if rand.Intn(2) == 0 {
return stepOne(ctx)
}
return stepTwo(ctx)
}
```
**Correct (non-determinism in step):**
```go
func exampleWorkflow(ctx dbos.DBOSContext, input string) (string, error) {
// Step result is checkpointed - replay uses the saved value
choice, err := dbos.RunAsStep(ctx, func(ctx context.Context) (int, error) {
return rand.Intn(2), nil
}, dbos.WithStepName("generateChoice"))
if err != nil {
return "", err
}
if choice == 0 {
return stepOne(ctx)
}
return stepTwo(ctx)
}
```
Non-deterministic operations that must be in steps:
- Random number generation
- Getting current time (`time.Now()`)
- Accessing external APIs (`http.Get`, etc.)
- Reading files
- Database queries

---
## List and Inspect Workflows
Use `dbos.ListWorkflows` to query workflow executions by status, name, time range, and other criteria.
**Incorrect (no monitoring of workflow state):**
```go
// Start workflow with no way to check on it later
dbos.RunWorkflow(ctx, processTask, "data")
// If something goes wrong, no way to find or debug it
```
**Correct (listing and inspecting workflows):**
```go
// List workflows by status
erroredWorkflows, err := dbos.ListWorkflows(ctx,
dbos.WithStatus([]dbos.WorkflowStatusType{dbos.WorkflowStatusError}),
)
for _, wf := range erroredWorkflows {
fmt.Printf("Workflow %s: %s - %v\n", wf.ID, wf.Name, wf.Error)
}
```
List workflows with multiple filters:
```go
workflows, err := dbos.ListWorkflows(ctx,
dbos.WithName("processOrder"),
dbos.WithStatus([]dbos.WorkflowStatusType{dbos.WorkflowStatusSuccess}),
dbos.WithLimit(100),
dbos.WithSortDesc(),
dbos.WithLoadOutput(true),
)
```
List workflow steps:
```go
steps, err := dbos.GetWorkflowSteps(ctx, workflowID)
for _, step := range steps {
fmt.Printf("Step %d: %s\n", step.StepID, step.StepName)
if step.Error != nil {
fmt.Printf(" Error: %v\n", step.Error)
}
if step.ChildWorkflowID != "" {
fmt.Printf(" Child: %s\n", step.ChildWorkflowID)
}
}
```
Workflow status values: `WorkflowStatusPending`, `WorkflowStatusEnqueued`, `WorkflowStatusSuccess`, `WorkflowStatusError`, `WorkflowStatusCancelled`, `WorkflowStatusMaxRecoveryAttemptsExceeded`
To optimize performance, avoid loading inputs/outputs when you don't need them (they are not loaded by default).

title: Set Workflow Timeouts
impact: CRITICAL
impactDescription: Prevents workflows from running indefinitely
tags: workflow, timeout, cancellation, duration
---
## Set Workflow Timeouts
Set a timeout for a workflow by using Go's `context.WithTimeout` or `dbos.WithTimeout` on the DBOS context. When the timeout expires, the workflow and all its children are cancelled.
**Incorrect (no timeout for potentially long workflow):**
```go
// No timeout - could run indefinitely
handle, err := dbos.RunWorkflow(ctx, processTask, "data")
```
**Correct (with timeout):**
```go
// Create a context with a 5-minute timeout
timedCtx, cancel := dbos.WithTimeout(ctx, 5*time.Minute)
defer cancel()
handle, err := dbos.RunWorkflow(timedCtx, processTask, "data")
if err != nil {
log.Fatal(err)
}
```
Key timeout behaviors:
- Timeouts are **start-to-completion**: the timeout begins when the workflow starts execution, not when it's enqueued
- Timeouts are **durable**: they persist across restarts, so workflows can have very long timeouts (hours, days, weeks)
- Cancellation happens at the **beginning of the next step** - the current step completes first
- Cancelling a workflow also cancels all **child workflows**

# DBOS Python Best Practices
Guide for building reliable, fault-tolerant Python applications with DBOS durable workflows.
## When to Use
Reference these guidelines when:
- Adding DBOS to existing Python code
- Creating workflows and steps
- Using queues for concurrency control
- Implementing workflow communication (events, messages, streams)
- Configuring and launching DBOS applications
- Using DBOSClient from external applications
- Testing DBOS applications

|----------|----------|--------|--------|
| 1 | Lifecycle | CRITICAL | `lifecycle-` |
| 2 | Workflow | CRITICAL | `workflow-` |
| 3 | Step | HIGH | `step-` |
| 4 | Queue | HIGH | `queue-` |
| 5 | Communication | MEDIUM | `comm-` |
| 6 | Pattern | MEDIUM | `pattern-` |
| 7 | Testing | LOW-MEDIUM | `test-` |
| 8 | Client | MEDIUM | `client-` |
| 9 | Advanced | LOW | `advanced-` |
## Critical Rules
### DBOS Configuration and Launch
A DBOS application MUST configure and launch DBOS inside its main function:
```python
import os
from dbos import DBOS, DBOSConfig
@DBOS.workflow()
def my_workflow():
pass
if __name__ == "__main__":
config: DBOSConfig = {
"name": "my-app",
"system_database_url": os.environ.get("DBOS_SYSTEM_DATABASE_URL"),
}
DBOS(config=config)
DBOS.launch()
```
### Workflow and Step Structure
Workflows are comprised of steps. Any function performing complex operations or accessing external services must be a step:
```python
@DBOS.step()
def call_external_api():
return requests.get("https://api.example.com").json()
@DBOS.workflow()
def my_workflow():
result = call_external_api()
return result
```
### Key Constraints
- Do NOT call `DBOS.start_workflow` or `DBOS.recv` from a step
- Do NOT use threads to start workflows - use `DBOS.start_workflow` or queues
- Workflows MUST be deterministic - non-deterministic operations go in steps
- Do NOT create/update global variables from workflows or steps
## How to Use
Read individual rule files for detailed explanations and examples:
```
references/lifecycle-config.md
references/workflow-determinism.md
references/queue-concurrency.md
```

title: Use Async Workflows Correctly
impact: LOW
impactDescription: Enables non-blocking I/O in workflows
tags: async, coroutine, await, asyncio
---
## Use Async Workflows Correctly
Coroutine (async) functions can be DBOS workflows. Use async-specific methods and patterns.
**Incorrect (mixing sync and async):**
```python
@DBOS.workflow()
async def async_workflow():
# Don't use sync sleep in async workflow!
DBOS.sleep(10)
# Don't use sync start_workflow for async workflows
handle = DBOS.start_workflow(other_async_workflow)
```
**Correct (async patterns):**
```python
import asyncio
import aiohttp
@DBOS.step()
async def fetch_async():
async with aiohttp.ClientSession() as session:
async with session.get("https://example.com") as response:
return await response.text()
@DBOS.workflow()
async def async_workflow():
# Use async sleep
await DBOS.sleep_async(10)
# Await async steps
result = await fetch_async()
# Use async start_workflow
handle = await DBOS.start_workflow_async(other_async_workflow)
return result
```
### Running Async Steps In Parallel
You can run async steps in parallel if they are started in **deterministic order**:
**Correct (deterministic start order):**
```python
@DBOS.workflow()
async def parallel_workflow():
# Start steps in deterministic order, then await together
tasks = [
asyncio.create_task(step1("arg1")),
asyncio.create_task(step2("arg2")),
asyncio.create_task(step3("arg3")),
]
# Use return_exceptions=True for proper error handling
results = await asyncio.gather(*tasks, return_exceptions=True)
return results
```
**Incorrect (non-deterministic order):**
```python
@DBOS.workflow()
async def bad_parallel_workflow():
async def seq_a():
await step1("arg1")
await step2("arg2") # Order depends on step1 timing
async def seq_b():
await step3("arg3")
await step4("arg4") # Order depends on step3 timing
# step2 and step4 may run in either order - non-deterministic!
await asyncio.gather(seq_a(), seq_b())
```
If you need concurrent sequences, use child workflows instead of interleaving steps.
For transactions in async workflows, use `asyncio.to_thread`:
```python
@DBOS.transaction()
def sync_transaction(data):
DBOS.sql_session.execute(...)
@DBOS.workflow()
async def async_workflow():
result = await asyncio.to_thread(sync_transaction, data)
```

title: Use Patching for Safe Workflow Upgrades
impact: LOW
impactDescription: Deploy breaking changes without disrupting in-progress workflows
tags: patching, upgrade, versioning, migration
---
## Use Patching for Safe Workflow Upgrades
Use `DBOS.patch()` to safely deploy breaking workflow changes. Breaking changes alter what steps run or their order.
**Incorrect (breaking change without patch):**
```python
# Original
@DBOS.workflow()
def workflow():
foo()
bar()
# Updated - breaks in-progress workflows!
@DBOS.workflow()
def workflow():
baz() # Replaced foo() - checkpoints don't match
bar()
```
**Correct (using patch):**
```python
# Enable patching in config
config: DBOSConfig = {
"name": "my-app",
"enable_patching": True,
}
DBOS(config=config)
@DBOS.workflow()
def workflow():
if DBOS.patch("use-baz"):
baz() # New workflows use baz
else:
foo() # Old workflows continue with foo
bar()
```
Deprecating patches after all old workflows complete:
```python
# Step 1: Deprecate (runs all workflows, stops inserting marker)
@DBOS.workflow()
def workflow():
DBOS.deprecate_patch("use-baz")
baz()
bar()
# Step 2: Remove entirely (after all deprecated workflows complete)
@DBOS.workflow()
def workflow():
baz()
bar()
```
`DBOS.patch(name)` returns:
- `True` for new workflows (started after patch deployed)
- `False` for old workflows (started before patch deployed)

title: Use Versioning for Blue-Green Deployments

impactDescription: Safely deploy new code with version tagging
tags: versioning, blue-green, deployment, recovery
---
## Use Versioning for Blue-Green Deployments
DBOS versions workflows to prevent unsafe recovery. Use blue-green deployments to safely upgrade.
**Incorrect (deploying breaking changes without versioning):**
```python
# Deploying new code directly kills in-progress workflows
# because their checkpoints don't match the new code
# Old code
@DBOS.workflow()
def workflow():
step_a()
step_b()
# New code replaces old immediately - breaks recovery!
@DBOS.workflow()
def workflow():
step_a()
step_c() # Changed step - old workflows can't recover
```
**Correct (using versioning with blue-green deployment):**
```python
# Set explicit version in config
config: DBOSConfig = {
"name": "my-app",
"application_version": "2.0.0", # New version
}

title: Enqueue Workflows from External Applications
impact: HIGH
impactDescription: Enables decoupled architecture with separate API and worker services
tags: client, enqueue, workflow, external
---
## Enqueue Workflows from External Applications
Use `client.enqueue()` to submit workflows from outside the DBOS application. Must specify workflow and queue names explicitly.
**Incorrect (missing required options):**
```python
from dbos import DBOSClient
client = DBOSClient(system_database_url=db_url)
# Missing workflow_name and queue_name!
handle = client.enqueue({}, task_data)
```
**Correct (with required options):**
```python
from dbos import DBOSClient, EnqueueOptions
client = DBOSClient(system_database_url=db_url)
options: EnqueueOptions = {
"workflow_name": "process_task", # Required
"queue_name": "task_queue", # Required
}
handle = client.enqueue(options, task_data)
result = handle.get_result()
client.destroy()
```
With optional parameters:
```python
options: EnqueueOptions = {
"workflow_name": "process_task",
"queue_name": "task_queue",
"workflow_id": "custom-id-123",
"workflow_timeout": 300,
"deduplication_id": "user-123",
"priority": 1,
}
```
Limitation: Cannot enqueue workflows that are methods on Python classes.

tags: client, setup, initialization, external
---
## Initialize DBOSClient for External Access
Use `DBOSClient` to interact with DBOS from external applications (API servers, CLI tools, etc.).
**Incorrect (no cleanup):**
```python
from dbos import DBOSClient
client = DBOSClient(system_database_url=db_url)
handle = client.enqueue(options, data)
# Connection leaked - no destroy()!
```
**Correct (with cleanup):**
```python
import os
from dbos import DBOSClient
client = DBOSClient(
system_database_url=os.environ["DBOS_SYSTEM_DATABASE_URL"]
)
try:
handle = client.enqueue(options, data)
result = handle.get_result()
finally:
client.destroy()
```
Constructor parameters:
- `system_database_url`: Connection string to DBOS system database
- `serializer`: Must match the DBOS application's serializer (default: pickle)
## API Reference
Beyond `enqueue`, DBOSClient mirrors the DBOS API. Use the same patterns from other reference files:
| DBOSClient method | Same as DBOS method |
|-------------------|---------------------|
| `client.send()` | `DBOS.send()` - add `idempotency_key` for exactly-once |
| `client.get_event()` | `DBOS.get_event()` |
| `client.read_stream()` | `DBOS.read_stream()` |
| `client.list_workflows()` | `DBOS.list_workflows()` |
| `client.cancel_workflow()` | `DBOS.cancel_workflow()` |
| `client.resume_workflow()` | `DBOS.resume_workflow()` |
| `client.retrieve_workflow()` | `DBOS.retrieve_workflow()` |

tags: events, set_event, get_event, status
---
## Use Events for Workflow Status Publishing
Workflows can publish key-value events that clients can read. Events are persisted and useful for status updates.
**Incorrect (no way to monitor progress):**
```python
@DBOS.workflow()
def long_workflow():
step_one()
step_two() # Client can't see progress
step_three()
return "done"
```
**Correct (publishing events):**
```python
@DBOS.workflow()
def long_workflow():
DBOS.set_event("status", "starting")
step_one()
DBOS.set_event("status", "step_one_complete")
step_two()
DBOS.set_event("status", "step_two_complete")
step_three()
DBOS.set_event("status", "finished")
return "done"
# Client code to read events
@app.post("/start")
def start_workflow():
handle = DBOS.start_workflow(long_workflow)
return {"workflow_id": handle.get_workflow_id()}
@app.get("/status/{workflow_id}")
def get_status(workflow_id: str):
status = DBOS.get_event(workflow_id, "status", timeout_seconds=0) or "not started"
return {"status": status}
```
Get all events from a workflow:
```python
all_events = DBOS.get_all_events(workflow_id)
# Returns: {"status": "finished", "other_key": "value"}
```
Events can be called from `set_event` from workflows or steps.

## Use Messages for Workflow Notifications
Send messages to workflows to signal or notify them while running. Messages are persisted and queued per topic.
**Incorrect (polling external state):**
```python
@DBOS.workflow()
def payment_workflow():
# Polling is inefficient and not durable
while True:
status = check_payment_status()
if status == "paid":

**Correct (using messages):**
```python
PAYMENT_STATUS = "payment_status"
@DBOS.workflow()
def payment_workflow():
# Process order...
DBOS.set_event("payment_id", payment_id)
# Wait for payment notification (60 second timeout)
payment_status = DBOS.recv(PAYMENT_STATUS, timeout_seconds=60)
if payment_status == "paid":
fulfill_order()
else:
cancel_order()

@app.post("/payment_webhook/{workflow_id}/{status}")
def payment_webhook(workflow_id: str, status: str):
DBOS.send(workflow_id, status, PAYMENT_STATUS)

Key points:
- `DBOS.recv()` can only be called from workflows
- Messages are queued per topic
- `recv()` returns `None` on timeout
- Messages are persisted for exactly-once delivery

## Use Streams for Real-Time Data
Workflows can stream data in real-time to clients. Useful for LLM responses, progress reporting, or long-running results.
**Incorrect (returning all data at end):**
```python
@DBOS.workflow()
def llm_workflow(prompt):
# Client waits for entire response
response = call_llm(prompt)
return response
```
**Correct (streaming results):**
```python
@DBOS.workflow()
def llm_workflow(prompt):
for chunk in call_llm_streaming(prompt):
DBOS.write_stream("response", chunk)
DBOS.close_stream("response")
return "complete"
# Client reads stream
@app.get("/stream/{workflow_id}")
def stream_response(workflow_id: str):
def generate():
for value in DBOS.read_stream(workflow_id, "response"):
yield value
return StreamingResponse(generate())
```
Stream characteristics:
- Streams are immutable and append-only
- Writes from workflows happen exactly-once
- Writes from steps happen at-least-once (may duplicate on retry)
- Streams auto-close when workflow terminates
Close streams explicitly when done:
```python
@DBOS.workflow()
def producer():
DBOS.write_stream("data", {"step": 1})
DBOS.write_stream("data", {"step": 2})
DBOS.close_stream("data") # Signal completion

## Use DBOS Decorators with Classes
DBOS decorators work with class methods. Workflow classes must inherit from `DBOSConfiguredInstance`.

class MyService:
def __init__(self, url):
self.url = url
@DBOS.workflow() # Won't work without proper setup

```python
from dbos import DBOS, DBOSConfiguredInstance
@DBOS.dbos_class()
class URLFetcher(DBOSConfiguredInstance):
def __init__(self, url: str):
self.url = url
# instance_name must be unique and passed to super()
super().__init__(instance_name=url)
@DBOS.workflow()
def fetch_workflow(self):
return self.fetch_url()
@DBOS.step()
def fetch_url(self):
return requests.get(self.url).text
# Instantiate BEFORE DBOS.launch()
example_fetcher = URLFetcher("https://example.com")
api_fetcher = URLFetcher("https://api.example.com")
if __name__ == "__main__":
DBOS.launch()
print(example_fetcher.fetch_workflow())
```
Requirements:
- Class must be decorated with `@DBOS.dbos_class()`
- Class must inherit from `DBOSConfiguredInstance`
- `instance_name` must be unique and passed to `super().__init__()`
- All instances must be created before `DBOS.launch()`
Steps can be added to any class without these requirements.

## Debounce Workflows to Prevent Wasted Work
Debouncing delays workflow execution until some time has passed since the last trigger. Useful for user input processing.
**Incorrect (processing every input):**
```python
@DBOS.workflow()
def process_input(user_input):
# Expensive processing
analyze(user_input)
@app.post("/input")
def on_input(user_id: str, input: str):
# Every keystroke triggers processing!
DBOS.start_workflow(process_input, input)
```
**Correct (debounced processing):**
```python
from dbos import Debouncer
@DBOS.workflow()
def process_input(user_input):
analyze(user_input)
# Create a debouncer for the workflow
debouncer = Debouncer.create(process_input)
@app.post("/input")
def on_input(user_id: str, input: str):
# Wait 5 seconds after last input before processing
debounce_key = user_id # Debounce per user
debounce_period = 5.0 # Seconds
handle = debouncer.debounce(debounce_key, debounce_period, input)
return {"workflow_id": handle.get_workflow_id()}
```
Debouncer with timeout (max wait time):
```python
# Process after 5s idle OR 60s max wait
debouncer = Debouncer.create(process_input, debounce_timeout_sec=60)
def on_input(user_id: str, input: str):
debouncer.debounce(user_id, 5.0, input)
```
When workflow executes, it uses the **last** inputs passed to `debounce`.

## Use Workflow IDs for Idempotency
Set workflow IDs to make operations idempotent. A workflow with the same ID executes only once.
**Incorrect (duplicate payments possible):**
```python
@app.post("/pay/{order_id}")
def process_payment(order_id: str):
# Multiple clicks = multiple payments!
handle = DBOS.start_workflow(payment_workflow, order_id)
return handle.get_result()
```
**Correct (idempotent with workflow ID):**
```python
from dbos import SetWorkflowID
@app.post("/pay/{order_id}")
def process_payment(order_id: str):
# Same order_id = same workflow ID = only one execution
with SetWorkflowID(f"payment-{order_id}"):
handle = DBOS.start_workflow(payment_workflow, order_id)
return handle.get_result()
@DBOS.workflow()
def payment_workflow(order_id: str):
charge_customer(order_id)
send_confirmation(order_id)
return "success"
```
Access the workflow ID inside workflows:
```python
@DBOS.workflow()
def my_workflow():
current_id = DBOS.workflow_id
DBOS.logger.info(f"Running workflow {current_id}")
```
Workflow IDs must be globally unique. Duplicate IDs return the existing workflow's result without re-executing.

## Create Scheduled Workflows
Use `@DBOS.scheduled` to run workflows on a schedule. Workflows run exactly once per interval.
**Incorrect (manual scheduling):**
```python
# Don't use external cron or manual timers
import schedule
schedule.every(1).minute.do(my_task)
```
**Correct (DBOS scheduled workflow):**
```python
@DBOS.scheduled("* * * * *") # Every minute
@DBOS.workflow()
def run_every_minute(scheduled_time, actual_time):
print(f"Running at {scheduled_time}")
do_maintenance_task()
@DBOS.scheduled("0 */6 * * *") # Every 6 hours
@DBOS.workflow()
def periodic_cleanup(scheduled_time, actual_time):
cleanup_old_records()
```
Scheduled workflow requirements:
- Must have `@DBOS.scheduled` decorator with crontab syntax
- Must accept two arguments: `scheduled_time` and `actual_time` (both `datetime`)
- Main thread must stay alive for scheduled workflows
For apps with only scheduled workflows (no HTTP server):
```python
import threading
if __name__ == "__main__":
DBOS.launch()
threading.Event().wait() # Block forever
```
Crontab format: `minute hour day month weekday`
- `* * * * *` = every minute
- `0 * * * *` = every hour
- `0 0 * * *` = daily at midnight
- `0 0 * * 0` = weekly on Sunday

# Regular sleep is lost on restart!
time.sleep(delay_seconds)
run_task(task)

**Correct (durable sleep):**
```python
@DBOS.workflow()
def delayed_task(delay_seconds, task):
# Durable sleep - survives restarts
DBOS.sleep(delay_seconds)
run_task(task)
```
Use cases for durable sleep:
- Schedule a task for the future
- Wait between retries
- Implement delays spanning hours, days, or weeks
Example: Schedule a reminder:
```python
@DBOS.workflow()
def send_reminder(user_id: str, message: str, delay_days: int):
# Sleep for days - survives any restart
DBOS.sleep(delay_days * 24 * 60 * 60)
send_notification(user_id, message)
```
For async workflows, use `DBOS.sleep_async()`:
```python
@DBOS.workflow()
async def async_delayed_task():
await DBOS.sleep_async(60)
await run_async_task()
```

# Queue manages concurrency
handle = queue.enqueue(process_task, task)
handles.append(handle)
# Wait for all tasks
return [h.get_result() for h in handles]

Queues support worker-level and global concurrency limits to prevent resource exhaustion.
**Incorrect (no concurrency control):**
```python

# Uses lots of memory
pass

**Correct (worker concurrency):**
```python
# Each process runs at most 5 tasks from this queue
queue = Queue("heavy_tasks", worker_concurrency=5)
@DBOS.workflow()
def memory_intensive_task(data):
pass
```
**Correct (global concurrency):**
```python
# At most 10 tasks run across ALL processes
queue = Queue("limited_tasks", concurrency=10)
```
**In-order processing (sequential):**
```python
# Only one task at a time - guarantees order
queue = Queue("sequential_queue", concurrency=1)
@DBOS.step()
def process_event(event):
pass
def handle_event(event):
queue.enqueue(process_event, event)
```
Worker concurrency is recommended for most use cases. Global concurrency should be used carefully as pending workflows count toward the limit.

tags: queue, deduplication, duplicate, idempotent
---
## Deduplicate Queued Workflows
Use deduplication IDs to ensure only one workflow with a given ID is active in a queue at a time.
**Incorrect (duplicate workflows possible):**
```python
queue = Queue("user_tasks")
@app.post("/process/{user_id}")
def process_for_user(user_id: str):
# Multiple requests = multiple workflows for same user!
queue.enqueue(process_workflow, user_id)
```
**Correct (deduplicated by user):**
```python
from dbos import Queue, SetEnqueueOptions
from dbos import error as dboserror
queue = Queue("user_tasks")
@app.post("/process/{user_id}")
def process_for_user(user_id: str):
with SetEnqueueOptions(deduplication_id=user_id):
try:
handle = queue.enqueue(process_workflow, user_id)
return {"workflow_id": handle.get_workflow_id()}
except dboserror.DBOSQueueDeduplicatedError:
return {"status": "already processing"}
```
Deduplication behavior:
- If a workflow with the same deduplication ID is `ENQUEUED` or `PENDING`, new enqueue raises `DBOSQueueDeduplicatedError`
- Once the workflow completes, a new workflow with the same ID can be enqueued
- Deduplication is per-queue (same ID can exist in different queues)
Use cases:
- One active task per user
- Preventing duplicate job submissions
- Rate limiting by entity

## Control Which Queues a Worker Listens To
Use `DBOS.listen_queues()` to make a process only handle specific queues. Useful for CPU vs GPU workers.
**Incorrect (all workers handle all queues):**

# Every worker processes both queues
# GPU tasks may run on CPU-only machines!

cpu_queue = Queue("cpu_queue")
gpu_queue = Queue("gpu_queue")
@DBOS.workflow()
def cpu_task(data):
pass

if worker_type == "gpu":
DBOS.listen_queues([gpu_queue])
elif worker_type == "cpu":
DBOS.listen_queues([cpu_queue])

Key points:
- Call `DBOS.listen_queues()` **before** `DBOS.launch()`
- Workers can still **enqueue** to any queue, just won't **dequeue** from others
- By default, workers listen to all declared queues

queue.enqueue(process_task, task)
```
For both per-partition AND global limits, use two-level queueing:
```python
# Global limit of 5 concurrent tasks
global_queue = Queue("global_queue", concurrency=5)
# Per-user limit of 1 concurrent task
user_queue = Queue("user_queue", partition_queue=True, concurrency=1)
def handle_task(user_id: str, task):
with SetEnqueueOptions(queue_partition_key=user_id):
user_queue.enqueue(concurrency_manager, task)
@DBOS.workflow()
def concurrency_manager(task):
# Enforces global limit
return global_queue.enqueue(process_task, task).get_result()
@DBOS.workflow()
def process_task(task):
pass
```

## Set Queue Priority for Workflows
Use priority to control which workflows run first. Lower numbers = higher priority.
**Incorrect (no priority control):**
```python
queue = Queue("tasks")
# All tasks treated equally - urgent tasks may wait
for task in tasks:
queue.enqueue(process_task, task)
```
**Correct (with priority):**
```python
from dbos import Queue, SetEnqueueOptions
# Must enable priority on the queue
queue = Queue("tasks", priority_enabled=True)
@DBOS.workflow()
def process_task(task):
pass
def enqueue_task(task, is_urgent: bool):
# Priority 1 = highest, runs before priority 10
priority = 1 if is_urgent else 10
with SetEnqueueOptions(priority=priority):
queue.enqueue(process_task, task)
```
Priority behavior:
- Range: 1 to 2,147,483,647 (lower = higher priority)
- Workflows without priority have highest priority (run first)
- Same priority = FIFO order
- Must set `priority_enabled=True` on queue
Example with multiple priority levels:
```python
queue = Queue("jobs", priority_enabled=True)
PRIORITY_CRITICAL = 1
PRIORITY_HIGH = 10
PRIORITY_NORMAL = 100
PRIORITY_LOW = 1000
def enqueue_job(job, level):
with SetEnqueueOptions(priority=level):
queue.enqueue(process_job, job)
```

title: Rate Limit Queue Execution
impact: HIGH
impactDescription: Prevents hitting API rate limits
tags: queue, rate-limit, api, throttle

## Rate Limit Queue Execution
Use rate limits when working with rate-limited APIs (like LLM APIs). Limits are global across all processes.
**Incorrect (no rate limiting):**
```python
queue = Queue("llm_tasks")
@DBOS.step()
def call_llm(prompt):
# May hit rate limits if too many calls
return openai.chat.completions.create(...)
```
**Correct (with rate limit):**
```python
# Max 50 tasks started per 30 seconds
queue = Queue("llm_tasks", limiter={"limit": 50, "period": 30})
@DBOS.step()
def call_llm(prompt):
return openai.chat.completions.create(...)
@DBOS.workflow()
def process_prompts(prompts):
handles = []
for prompt in prompts:
# Queue enforces rate limit
handle = queue.enqueue(call_llm, prompt)
handles.append(handle)
return [h.get_result() for h in handles]
```
Rate limit parameters:
- `limit`: Maximum number of functions to start in the period
- `period`: Time period in seconds
Rate limits can be combined with concurrency limits:
```python
queue = Queue("api_tasks",
worker_concurrency=5,
limiter={"limit": 100, "period": 60})
```
