### For v1.1 (1-2 weeks)

- Fix type safety issues (3-5 days effort)
- Address CLI minor warnings (1-2 weeks)
- Improve documentation based on user feedback

### For v2.0 (2-3 months)

- Achieve 70%+ Go test coverage (4-6 weeks)
- Achieve 100% Python service coverage (4-6 weeks)
- Address all lint warnings (2-4 days)
- Consider basedpyright adoption for ultra-strict typing
