Awesome SKILL.md

A curated list of SKILL.md skills, tools, and resources for AI coding agents.

SKILL.md is the open standard for teaching AI coding agents new capabilities. A SKILL.md file tells agents like Claude Code, Codex CLI, Cursor, Gemini CLI, and OpenClaw how to handle specific tasks — code review, testing, documentation, DevOps, and more. Drop a skill into your agent's skills folder and it works immediately.

This list covers the best skills, resources, and tools across the ecosystem.
