FAQ

How to choose skills for this workflow

These answers are written for both human builders and agents consuming the Registry API.

What are the best AI agent skills for testing and qa?

Start by comparing Testcafe, Webapp Testing, Playwright. OpenAgentSkill ranks them by workflow fit, GitHub adoption, trust score, safety gate, and install readiness.

Can an AI agent use this page directly?

Yes. Use the linked Registry API prompt to query /api/skills/search with the task: "I need my agent to test a web app, reproduce bugs, and verify fixes." and retrieve install handoff links for the top results.

Should I install every recommended skill?

No. Start with the highest-fit skill, test it in a sandbox workflow, and add companion skills only when the task needs extra coverage.
