Find a useful skill once, then use the compatible package with Claude, Codex, GPT, Gemini, Cursor or OpenCode.
Why the registry exists
AI agents increasingly depend on reusable instructions, tools and workflows, but every ecosystem packages those capabilities differently. That fragmentation makes skills difficult to discover, compare and maintain. AI Skills Catalog treats the skill as the primary functional unit and each plugin, rule or extension as a distribution format.
Discover
Search a structured catalog instead of browsing disconnected repositories.
Compare
Review compatibility, permissions, licenses, activity and quality signals.
Install
Choose your AI agent and obtain the appropriate package format.
Independent by design
Listings are evaluated using published criteria for source identity, maintenance, permissions, compatibility and security signals. Commercial relationships never buy verification or a higher Skill Score.
Open ecosystem
Authors retain ownership of their work. We preserve source attribution and license information while helping users understand which agent formats are available. Read our evaluation methodology and conversion process.
