## How this list was made

- Every skill on appsgit (1,000) works with Claude Code, so this ranking covers the whole collection.
- Ranked by GitHub stars (installs on skills.sh break ties), at most one entry per repository so one project cannot fill the list.
- The catalog itself only lists skills with a valid SKILL.md, a license and a commit in the last six months, from repositories with 100+ stars or a skills.sh listing.

## FAQ

### Do these agent skills need an API key?

None of the 10 picks needs an API key or token according to their published configuration.

### Which coding agents work with these skills?

Claude Code (all), Codex (6 of 10), Cursor (6 of 10) and GitHub Copilot (5 of 10). The client list comes from each project's published compatibility data; appsgit does not guess it.

### Are any of these agent skills official?

Yes: Frontend Design and Next Bundle Optimizer are published by the vendor themselves.

### How do I install an agent skill?

A skill is a folder with a SKILL.md file that you copy into your agent's skills directory, or install from a plugin marketplace when the repository is one. Every skill page on appsgit shows the install command.
