How to install an Agent Skill
Every skill is a single file served at /skills/<name>/SKILL.md. Put it in a folder with the same name inside your agent's skills directory:
| Agent | Personal (all projects) | Project (commit to repo) |
|---|---|---|
| Claude Code | ~/.claude/skills/<name>/SKILL.md | .claude/skills/<name>/SKILL.md |
| OpenAI Codex | ~/.agents/skills/<name>/SKILL.md | .agents/skills/<name>/SKILL.md |
| Cursor | ~/.cursor/skills/ or ~/.agents/skills/ | .cursor/skills/ or .agents/skills/ |
