## Test Coverage

- **Total tools tested**: 16/16
- **All tools functional**: Yes
- **No errors encountered**: All operations succeeded
- **Edge cases tested**: File creation, editing, patching, searching, background tasks, agent cancellation

## Environment Details

- **Project**: deepseek-cli (Rust CLI application)
- **Workspace**: `/Volumes/VIXinSSD/deepseek-cli/`
- **Test artifacts**: `test_tool_check.txt`, `tool_test_report.md`
- **Testing approach**: Sequential verification with todo tracking

## Conclusion

All available tools in the DeepSeek CLI TUI environment are fully functional. The testing methodology used a structured todo system to ensure comprehensive coverage of each tool category. The agent system, file operations, shell execution, and task management tools all performed as expected.

**Final status**: ✅ All tools working correctly
