Testing and quality skills for AI agents.

The library's testing and quality skills include Accessibility Tester, API Fuzzer and API Testing Quickstart. They cover testing and quality, test methodology, test automation, and quality metrics. 25 passed Skill Guard clean. The other 1 switch on only after you have read them and said yes. Skills are written instructions, not app connections: a bot reads the one a job calls for and works the way it lays out. Add any of them to a bot in Settings → Skills, or tell your Chief of Staff the job and let it choose.
