Migrate to Claude Agent SDK framework (v0.2.0) BREAKING CHANGE: Replaced FastAPI server wrapper with direct Claude Agent SDK integration ## Major Changes ### Architecture - **OLD:** Bot → FastAPI Server → claude-code-sdk → Claude - **NEW:** Bot → Claude Agent SDK → Claude (Pro subscription OR API) - Eliminated HTTP server overhead - Single-process architecture ### LLM Backend (llm_interface.py) - Implemented Claude Agent SDK as DEFAULT mode - Added three-mode architecture: - agent-sdk (default) - Uses Pro subscription - direct-api - Pay-per-token Anthropic API - legacy-server - Backward compat with old setup - Created async/sync bridge using anyio - Preserved all existing functionality (17 tools, memory, scheduling) ### Dependencies (requirements.txt) - Replaced: claude-code-sdk → claude-agent-sdk>=0.1.0 - Added: anyio>=4.0.0 for async bridging - Removed: fastapi, uvicorn (no longer needed for default mode) ### New Files - ajarbot.py - Unified launcher with pre-flight checks - run.bat - Windows one-command launcher (auto-setup) - pyproject.toml - Python package metadata - MIGRATION.md - Upgrade guide from old setup - AGENT_SDK_IMPLEMENTATION.md - Technical documentation - QUICK_REFERENCE_AGENT_SDK.md - Quick reference card - test_agent_sdk.py - Comprehensive test suite ### Updated Documentation - CLAUDE_CODE_SETUP.md - Rewritten for Agent SDK - README.md - Updated quick start for new default - .env.example - Added AJARBOT_LLM_MODE configuration ### Deleted Files - claude_code_server.py - Replaced by agent-sdk integration - heartbeat.py - Superseded by scheduled_tasks.py - pulse_brain.py - Unused in production ## Migration Path Old setup: 1. Start FastAPI server: python claude_code_server.py 2. Start bot: python bot_runner.py 3. Set USE_CLAUDE_CODE_SERVER=true New setup: 1. Run: run.bat (or python ajarbot.py) - That's it! Single command. ## Benefits ✅ Zero API costs (uses Claude Pro subscription) ✅ Simplified deployment (no separate server) ✅ Single-command launch (run.bat) ✅ Faster response times (no HTTP overhead) ✅ All functionality preserved (17 tools, memory, adapters) ✅ Backward compatible (old env vars still work) ## Compatibility - Python 3.10+ required - Node.js required (for Claude Code CLI bundled with SDK) - Windows 11 tested and optimized - All existing tools, memory system, and adapters unchanged Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

# Agent SDK Quick Reference Card
## 🚀 Quick Start
```bash
# Install dependencies
pip install -r requirements.txt
# Run bot (Agent SDK is default)
python bot_runner.py
```
## 📋 Mode Selection
### Agent SDK (Default)
```env
# No config needed - this is the default!
# Or explicitly:
USE_AGENT_SDK=true
```
✅ Uses Claude Pro subscription (no API costs)
### Direct API
```env
USE_DIRECT_API=true
ANTHROPIC_API_KEY=sk-ant-...
```
✅ Pay-per-token, usage tracking enabled
### Legacy Server
```env
USE_CLAUDE_CODE_SERVER=true
CLAUDE_CODE_SERVER_URL=http://localhost:8000
```
⚠️ Deprecated, not recommended
## 🔍 Verify Mode
Check startup message:
```
[LLM] Using Claude Agent SDK (Pro subscription) ← Agent SDK ✅
[LLM] Using Direct API (pay-per-token) ← Direct API 💳
[LLM] Using Claude Code server at ... ← Legacy ⚠️
```
## 🧪 Test Installation
```bash
python test_agent_sdk.py
```
Expected: **5/5 tests passed** 🎉
## 🛠️ Troubleshooting
### Issue: Fallback to Direct API
```bash
pip install claude-agent-sdk anyio
```
### Issue: ModuleNotFoundError
```bash
pip install -r requirements.txt
```
### Issue: Still using old mode
```bash
# Edit .env and remove conflicting variables
USE_DIRECT_API=false # or remove line
```
## 📊 Priority Order
```
1. USE_DIRECT_API=true → Direct API
2. USE_CLAUDE_CODE_SERVER → Legacy
3. USE_AGENT_SDK (default) → Agent SDK
4. SDK unavailable → Fallback to Direct API
```
## 💰 Cost Comparison
| Mode | Cost per 1M tokens |
|------|-------------------|
| Agent SDK | **$0** (Pro subscription) |
| Direct API (Haiku) | $0.25 - $1.25 |
| Direct API (Sonnet) | $3.00 - $15.00 |
## 🎯 Key Files
| File | Purpose |
|------|---------|
| `llm_interface.py` | Core implementation |
| `requirements.txt` | Dependencies |
| `test_agent_sdk.py` | Test suite |
| `.env` | Configuration |

## ✅ Features Preserved
✅ All 17 tools (file ops, Gmail, Calendar)
✅ Scheduled tasks
✅ Memory system
✅ Self-healing system
✅ Telegram adapter
✅ Slack adapter
✅ Model switching (/sonnet, /haiku)
✅ Usage tracking (Direct API mode)
## 🔄 Rollback
```env
# Quick rollback to Direct API
USE_DIRECT_API=true
ANTHROPIC_API_KEY=sk-ant-...
```
Restart bot. Done! ✅
