Paste a public GitHub repo. Every SKILL.md in it gets the same pattern check, format check and power level as the catalog, at the commit we read. It runs in your browser: nothing is sent to QAI.
GitHub allows about 60 unauthenticated requests an hour from your network; a large repo can use most of them.
See what Claude Code, the Claude apps, OpenAI and VS Code will reject, or build one that loads everywhere.
Send us a public repo with a SKILL.md.
