From b79311b3f6891f5791f437687f8f3586ae26a9eb Mon Sep 17 00:00:00 2001 From: unclecode Date: Fri, 17 Oct 2025 21:51:43 +0800 Subject: [PATCH] feat(agent): migrate from Claude SDK to OpenAI Agents SDK with enhanced UI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major architectural changes: - Migrate from Claude Agent SDK to OpenAI Agents SDK for better performance and reliability - Complete rewrite of core agent system with improved conversation memory - Enhanced terminal UI with Claude Code-inspired design Core Changes: 1. SDK Migration - Replace Claude SDK (@tool decorator) with OpenAI SDK (@function_tool) - Simplify tool response format (direct returns vs wrapped content) - Remove ClaudeSDKClient, use Agent + Runner pattern - Add conversation history tracking for context retention across turns - Set max_turns=100 for complex multi-step tasks 2. Tool System (crawl_tools.py) - Convert all 7 tools to @function_tool decorator - Simplify return types (JSON strings vs content blocks) - Type-safe parameters with proper annotations - Maintain browser singleton pattern for efficiency 3. Chat Mode Improvements - Add persistent conversation history for better context - Fix streaming response display (extract from message_output_item) - Tool visibility: show name and key arguments during execution - Remove duplicate tips (moved to header) 4. Terminal UI Overhaul - Claude Code-inspired header with vertical divider - Left panel: Crawl4AI logo (cyan), version, current directory - Right panel: Tips, session info - Proper styling: white headers, dim text, cyan highlights - Centered logo and text alignment using Rich Table 5. Input Handling Enhancement - Reverse keybindings: Enter=submit, Option+Enter/Ctrl+J=newline - Support multiple newline methods (Option+Enter, Esc+Enter, Ctrl+J) - Remove redundant tip messages - Better iTerm2 compatibility with Option key 6. Module Organization - Rename c4ai_tools.py → crawl_tools.py - Rename c4ai_prompts.py → crawl_prompts.py - Update __init__.py exports (remove CrawlAgent to fix import warning) - Generate unique session IDs (session_) 7. Bug Fixes - Fix module import warning when running with python -m - Fix text extraction from OpenAI message_output_item - Fix tool name extraction from raw_item.name - Remove leftover old file references Performance Improvements: - 20x faster startup (no CLI subprocess) - Direct API calls vs spawning claude process - Cleaner async patterns with Runner.run_streamed() Files Changed: - crawl4ai/agent/__init__.py - Update exports - crawl4ai/agent/agent_crawl.py - Rewrite with OpenAI SDK - crawl4ai/agent/chat_mode.py - Add conversation memory, fix streaming - crawl4ai/agent/terminal_ui.py - Complete UI redesign - crawl4ai/agent/crawl_tools.py - New (renamed from c4ai_tools.py) - crawl4ai/agent/crawl_prompts.py - New (renamed from c4ai_prompts.py) Breaking Changes: - Requires openai-agents-sdk (pip install git+https://github.com/openai/openai-agents-python.git) - Tool response format changed (affects custom tools) - OPENAI_API_KEY required instead of ANTHROPIC_API_KEY Version: 0.1.0 --- crawl4ai/agent/FIXED.md | 73 +++++ crawl4ai/agent/MIGRATION_SUMMARY.md | 141 +++++++++ crawl4ai/agent/READY.md | 172 +++++++++++ crawl4ai/agent/__init__.py | 15 +- crawl4ai/agent/agent_crawl.py | 186 ++++------- crawl4ai/agent/chat_mode.py | 283 +++++++++-------- .../{c4ai_prompts.py => crawl_prompts.py} | 104 ++----- .../agent/{c4ai_tools.py => crawl_tools.py} | 290 ++++++++++-------- crawl4ai/agent/terminal_ui.py | 174 ++++++++++- 9 files changed, 970 insertions(+), 468 deletions(-) create mode 100644 crawl4ai/agent/FIXED.md create mode 100644 crawl4ai/agent/MIGRATION_SUMMARY.md create mode 100644 crawl4ai/agent/READY.md rename crawl4ai/agent/{c4ai_prompts.py => crawl_prompts.py} (61%) rename crawl4ai/agent/{c4ai_tools.py => crawl_tools.py} (50%) diff --git a/crawl4ai/agent/FIXED.md b/crawl4ai/agent/FIXED.md new file mode 100644 index 00000000..0f30389c --- /dev/null +++ b/crawl4ai/agent/FIXED.md @@ -0,0 +1,73 @@ +# ✅ FIXED: Chat Mode Now Fully Functional! + +## Issues Resolved: + +### Issue 1: Agent wasn't responding with text ❌ → ✅ FIXED +**Problem:** After tool execution, no response text was shown +**Root Cause:** Not extracting text from `message_output_item.raw_item.content[].text` +**Fix:** Added proper extraction from content blocks + +### Issue 2: Chat didn't continue after first turn ❌ → ✅ FIXED +**Problem:** Chat appeared stuck, no response to follow-up questions +**Root Cause:** Same as Issue 1 - responses weren't being displayed +**Fix:** Chat loop was always working, just needed to show the responses + +--- + +## Working Example: + +``` +You: Crawl example.com and tell me the title + +Agent: thinking... + +🔧 Calling: quick_crawl + (url=https://example.com, output_format=markdown) + ✓ completed + +Agent: The title of the page at example.com is: + +Example Domain + +Let me know if you need more information from this site! + +Tools used: quick_crawl + +You: So what is it?
