What the skill teaches

A reference skill in the gh-aw repository on the file formats GitHub Copilot reads for custom instructions and custom agents. It explains where each kind of file goes and what it applies to: repository-wide instructions in .github/copilot-instructions.md, path-specific instruction files with an applyTo pattern, and custom agent profiles with YAML frontmatter that set tools and behaviour. An agent uses it to write, check and give examples of these files for a repository that uses Copilot.

Capabilities

  • Write repository-wide Copilot instruction files
  • Create path-specific instruction files with applyTo patterns
  • Define custom agent profiles with frontmatter
  • Check custom agent files against the expected format
