A skill is a portable skill.md file — YAML frontmatter plus a markdown body — that you drop into Claude Code, Cursor, Windsurf, Copilot, or any other AI tool that reads project instructions. Every entry here downloads in the format you need, and carries a community-verified compatibility matrix showing which tools it actually works with.
