- TypeScript implementation follows existing pattern
- Input schemas match backend requirements
- Error handling consistent with other tools
- Test coverage exists in mcp_spec.rb
- No security issues identified
### Tools Added
1. mark_busy - Marks current agent as busy

All three tools are properly implemented and tested. Ready to merge.
