See CONTRIBUTING.md to add new entries, or give your AI agent the CONTRIBUTE.md skill and it will do it automatically.

What Makes This Different

  • Not just links -- every entry has install commands, star counts, and verified metadata
  • Machine-readable catalogs -- query components programmatically via catalog.json files
  • Agent-contributable -- your AI agent can fork, add entries, validate JSON, and submit PRs automatically
  • Cross-platform -- works with 30+ AI coding assistants, not locked to one vendor
  • SKILL.md standard -- skills follow the open agentskills.io specification
