SkillsAllYouNeed for LLMs
The open registry of AI skills — ready-to-use capability definitions for Claude, Claude Code, ChatGPT, Codex, OpenCode, Cursor, Gemini, Perplexity, Microsoft 365 Copilot, GitHub Copilot, Antigravity, Kiro, and Pi.
What is this?
SkillsAllYouNeed is a searchable, filterable reference directory of every first-party skill, capability, tool, and extension shipping across the major AI assistant platforms. Think of it as an arXiv meets print magazine — editorial-preprint-styled, printable, and deep-linkable.
If you've ever asked "Can Claude do X?" or "How do I trigger ChatGPT's deep research?" — this is the answer page.

Contributing
Found a missing skill? Spotted an error? Two ways to help:
- Open an issue using the structured submission form
- Fork and PR — run
npm ci, add entries to the SKILLS array in data.js, then run npm run generate
Every entry needs: id, name, ecosystem, category, status, description, trigger, howto, example, source.
Run npm run validate before opening a PR. It checks the registry, comparison matrix, submission form, workflow, and generated skills.json.
