Create concise, Copilot-aware repository instructions, skills, and custom agents.
Create or modify repository guidance through GitHub Copilot CLI, including guidance consumed by Copilot code review. Use when asked to initialize, bootstrap, refresh, reorganize, or generate AGENTS.md, Copilot instructions, path-specific instructions, project skills, code-review guidance, or custom agents. Do not use for requests that only read or explain existing guidance.
