# TODO
## Recent Improvements (2026-02)
✅ **WatsonX Handshake Improvements**
- Token caching with 50-minute expiry (learned from TypeScript sdlcagent)

- Added `project_id` to request body
- Updated both `chat_completion` and `chat_completion_stream` methods
- All compiler warnings fixed (0 warnings)
- Removed redundant test example files
✅ **Codebase Simplification**
- Removed empty `docs/` folder
- Removed `.claude/` folder
- Removed `scripts/` folder
- Removed disabled example files
- Cleaned up all dead_code warnings with `#[allow(dead_code)]`

## Future Improvements
### Potential Features
- [x] Implement retry logic with exponential backoff ✅ **COMPLETED**
- [ ] Add support for more granular streaming control
- [ ] Implement connection pooling for better performance
- [ ] Add metrics and observability features
- [x] Support for batch requests ✅ **COMPLETED**
- [x] Chat completion API support ✅ **COMPLETED**
- [x] Add examples for different use cases (chat, code generation, etc.) ✅ **COMPLETED**
- [x] Implement caching for authentication tokens ✅ **COMPLETED**
- [ ] Investigate macOS sandbox crash (`system-configuration` panic) and make tests resilient:
- Prefer disabling system proxy auto-detection in the HTTP client (e.g. configure client to not consult OS proxy settings)
- Consider switching TLS/backend feature set to avoid `system-configuration` dependency if possible
- Add a regression note/test to ensure `cargo test` works in restricted environments (CI/sandbox) without panicking
### Documentation
- [ ] Add more detailed API documentation
- [ ] Add performance benchmarks
- [ ] Add troubleshooting guide
- [ ] Add migration guide from other SDKs
### Testing
- [ ] Add more integration tests
- [ ] Add real-API “contract” tests (no mocks) that validate request/response shapes against WatsonX endpoints
- [ ] Improve test coverage
- [ ] Add load testing scenarios
### Code Quality
- [ ] Add more code comments
- [x] Eliminate current `dead_code` warnings (keep `cargo test` and `cargo clippy` clean) ✅ **COMPLETED**
- [x] Refactor for better separation of concerns ✅ **COMPLETED**
- [x] Add clippy lints ✅ **COMPLETED**
- [x] Improve error messages ✅ **COMPLETED**
## Notes
### WatsonX AI (watsonx.ai)
- Supports both streaming (`generate_text_stream`) and non-streaming (`generate_text`) endpoints
- Authentication tokens are cached with expiry and auto-refresh (reduces IAM calls)
- Configuration is primarily via `.env` files for security
### WatsonX Orchestrate (watsonx.orchestrate)
- Simplified configuration following wxo-client-main pattern (only instance_id and region)
- Uses `/runs/stream` endpoint for all chat interactions (matches wxo-client)
- Supports both streaming (`stream_message`) and non-streaming (`send_message`) chat
- Maintains conversation context via thread_id (returned and managed by caller)
- Uses `IAM-API_KEY` header authentication (not Bearer token)
- Parses Orchestrate-specific SSE events (message.created, message.delta)
