• Dependencies: None (pure bash + Claude Code skills)
• Platform Support: macOS, Linux, Windows (WSL2/Git Bash)
• License: MIT

Testing

All commands execute successfully and provide expected output.

Why This PR?

These are temporary workarounds for real issues affecting hundreds of users. The plugin:

1. Helps users immediately while official fixes are developed
2. Demonstrates community contribution model
3. Can be deprecated once official fixes ship
4. Is opt-in (users install manually)

Related Work

This plugin was created after resolving 21+ GitHub issues with detailed technical analysis. See my comment history for root cause breakdowns on issues like #826 (218 comments), #769 (139 comments), etc.

Future Plans

As more issues are reported, additional commands can be added:

• /context-check - Validate token usage
• /hook-test - Test hook execution
• /config-validate - Full config file validation

Note: This is a community contribution to help users while official fixes are in progress. Happy to iterate on structure/implementation based on team feedback!
