## 🎯 Recommendations
### Immediate Priorities
1. **Complete Operations Layer** - Foundation for all future work
2. **Integrate with Portmanteau Tools** - Make new infrastructure usable
3. **Add Test Coverage** - Ensure quality and prevent regressions
### Strategic Priorities
1. **Phase 2-3 First** - Core functionality before advanced features
2. **Testing Throughout** - Don't defer testing to the end
3. **Documentation as You Go** - Keep docs in sync with code
### Risk Mitigation
1. **Incremental Integration** - Don't replace all mocks at once
2. **Feature Flags** - Allow rolling back to mocks if needed
3. **Comprehensive Testing** - Catch issues early
---
## 📝 Notes
### Architecture Decisions
- Using Pydantic models for type safety and validation
- Rate limiting built into client (not external service)
- Operations layer provides clean separation between API and tools
- Portmanteau pattern reduces tool explosion (10 tools vs 60+)
### Technical Debt
- Old api_client.py in root needs deprecation
- Some legacy code still using mock patterns
- Test coverage needs significant improvement
- Documentation needs completion for new components
### Future Considerations
- Consider async/await patterns throughout
- Evaluate caching strategies for frequently accessed data
- Plan for horizontal scaling if needed
- Consider GraphQL API if Tailscale adds support
