Pull request overview

This PR fixes the GitHub Copilot skill installation path to match the official GitHub documentation. The path was incorrectly set to .github/copilot/skills/gitbutler but should be .github/skills/gitbutler according to the official GitHub Copilot agent skills documentation.

Changes:

• Updated the GitHub Copilot skill format path constant in the skill command implementation

Thanks a lot, great catch!

I validated this and… second Copilot here :D.

@Byron Thanks for merging this so quickly!

In fact, this PR only fixes the project-level Copilot skill installation path (.github/skills). For global installation, Copilot uses a different location (.copilot/skills), while but skill install currently doesn't provide separate path for installing to the global scope (it only appends to the home path for now).

So unfortunately, the global Copilot installation path is still incorrect. Since it involves more extensive changes, I may not be able to address it :(.
