Skills Directory / Guides
Agent skills beyond Claude Code
SKILL.md is an open standard
(agentskills.io),
not a Claude Code feature. Most of the skills in our
directory work in Codex, Cursor, Gemini CLI, and
other agents with at most a different install path.
What transfers, what doesn't
Transfers directly: the skill itself — frontmatter (name, description) plus markdown instructions, reference files, and scripts. The content is agent-agnostic prose.
Claude Code-specific: plugins, marketplaces
(/plugin marketplace add), slash commands, and Claude-only
frontmatter extensions (tool restrictions, subagent hints). Other agents
ignore these gracefully; you just install by copying folders instead.
Compatibility table
| Agent | Where skills live | Notes |
|---|---|---|
| Claude Code | ~/.claude/skills/ (personal) · .claude/skills/ (project) | Native home of the format. Also supports plugins, marketplaces, slash commands. |
| OpenAI Codex | Agent skills directory per Codex docs | Reads SKILL.md; several major collections ship Codex install scripts. |
| Cursor | Project rules / skills directory | SKILL.md content transfers; Claude-specific frontmatter extensions are ignored. |
| Gemini CLI | Skills directory per Gemini CLI docs | Supports the agentskills.io standard. |
| GitHub Copilot | .github/copilot-instructions.md | No native SKILL.md support — paste the instruction body; frontmatter and dynamic features don't apply. |
| Others (OpenCode, Windsurf, Aider…) | Varies | Multi-tool collections like wshobson/agents and alirezarezvani/claude-skills ship converters. |
The universal install pattern
git clone https://github.com/owner/skills-repo
cp -r skills-repo/<skill-folder> <your-agent's-skills-directory>/Every skill page in our directory includes a copy-paste install prompt written to work agent-agnostically — it tells whatever agent you paste it into to detect its own skills directory and install there.
Cross-agent collections
If you run multiple agents, start with collections that maintain multi-tool support deliberately: wshobson/agents (6 harnesses) and alirezarezvani/claude-skills (13 tools, with conversion scripts). Official vendor skills (Cloudflare, Vercel, Hugging Face) are plain SKILL.md folders and work everywhere.
