Claude Code skills we have reviewed
A Claude Code skill is a folder with a SKILL.md file: a description of when to use it, instructions, and sometimes scripts. Claude Code keeps every description in context and loads the full instructions only when your request matches, so a good skill teaches the agent one job (building a UI, reviewing code, writing a grant, running a CLI) without costing context the rest of the time.
This page lists the 74 skills from 34 different authors that we have read at a fixed commit. For each one we note what it can do on your machine: whether it is instructions only, runs scripts, calls the network, needs an API key or writes files. Those findings are the tags on each card. We did not run the skills; read how we review for what a static review does and does not cover.
How to choose: start from the job, then check the tags. Skills marked instructions only change nothing outside your chat; skills marked runs scripts, installs packages or acts in your accounts deserve a look at their files before you install them. Every skill page has the source repository, the commit we read, and install steps for Claude Code and Antigravity skills folders.
Claude Code paths checked against Claude Code docs: Skills on 2026-10-12. Largest single author: 22% of the list. Independent site, not affiliated with Anthropic.
Install any of them in Claude Code
# all your projects mkdir -p ~/.claude/skills && cp -r <skill-folder> ~/.claude/skills/ # this repository only mkdir -p .claude/skills && cp -r <skill-folder> .claude/skills/
The exact source folder for each skill is on its page, together with the installer its own README documents (if any).

FAQ
- Where does Claude Code look for skills?
- Personal skills: ~/.claude/skills/<skill-name>/SKILL.md (all your projects). Project skills: .claude/skills/<skill-name>/SKILL.md (shared through the repository). Plugins can also bring skills.
- How do I use a skill once it is installed?
- Claude Code reads every skill description at the start of a session and loads the full SKILL.md when your request matches. You can also call one directly with /<skill-name>.
- Are these skills tested?
- No. We do a static review: we read the files at a fixed commit and note scripts, network calls, file writes and required keys. We did not run them. Each skill page shows the commit we read.
- Do the same skills work in Google Antigravity?
- A plain SKILL.md folder works in both. Antigravity reads it from .agents/skills/ (one project) or ~/.gemini/config/skills/ (all projects); each skill page has both install paths.
