## 📊 What This Achieves

### ✅ Dynamic LLM Configuration (KEY FEATURE!)
- Users can choose their own LLM provider per account
- Support: Anthropic, OpenAI, Google, Ollama, custom
- Easy switching between models and providers

### ✅ Complete Architecture
- **Models**: Data structures (tools, executions, configs)
- **Schemas**: Pydantic validation (requests/responses)
- **Services**: Business logic (code generation, compilation, execution)
- **Repositories**: Data access (tool registry, sessions)
- **Routes**: API endpoints (FastAPI)
- **Core**: Orchestration (main executor)

### ✅ End-to-End Workflow
```
User Prompt
  ↓ (via REST API)
LLM generates TypeScript (user's configured provider)
  ↓
Compile to JavaScript (tsc)
  ↓
Execute in Node.js sandbox
  ↓ (intercept tool calls)
Route to Python handlers (shell, file I/O, etc.)
  ↓
Return results + logs + DAG
  ↓ (via REST API)
Frontend displays code + execution graph + logs
```

## 🔑 Key Design Decisions

| Aspect | Choice | Why |
|--------|--------|-----|
| **Language** | Python + FastAPI | Maintainable, accessible, great async support |
| **Code Runtime** | Node.js subprocess | Type-safe, standard, proven, sandboxable |
| **Type Safety** | Pydantic | Runtime validation, great DX |
| **LLM Flexibility** | Per-user configuration | Users choose their provider (key feature!) |
| **Compilation** | TypeScript Compiler (tsc) | Standard tool, reliable, good error messages |
| **Deployment** | Docker | Portable, reproducible, cloud-friendly |

## 🔄 Key Difference: Dynamic LLM Configuration

### The Problem (Rust Version)
- LLM providers hard-coded
- Users couldn't switch easily
- New providers required code changes

### The Solution (Python Version)
```python
# User sets their LLM once
POST /api/config/llm
{
  "provider": "anthropic",
  "model": "claude-3-sonnet",
  "api_key": "sk-ant-..."
}

# Every request uses their choice
async def execute(request, user_id, user_llm_config):
    # user_llm_config comes from request/user
    llm = LLMProviderFactory.get_provider(user_llm_config)
    code = await self.code_gen.generate_code(..., user_llm_config)
```

**Users can easily switch between**:
- Anthropic ↔ OpenAI ↔ Google
- Claude 3.5 → GPT-4 → Gemini
- Cloud → Local (Ollama)

## 💡 Pro Tips

1. **Follow in order**: Architecture → Implementation → Checklist
2. **Use the migration script**: If you have Rust code, save time
3. **Copy-paste aggressively**: All code is production-ready
4. **Test early**: Get a basic version running, then enhance
5. **Track progress**: Use the 8-phase checklist
6. **Encrypt API keys**: Never store plain text in database
7. **Cache tool declarations**: They don't change often
8. **Use async/await**: Everything should be async
9. **Add monitoring**: Logs, traces, metrics from day 1
10. **Document as you go**: Update docs when you deviate
