Evaluation notes

What to check before installing

Install with a rollback mindset

Codex skills should be treated like workflow dependencies. Install them in a branch or sandbox, run a task, and keep a fallback path if the result is not reliable.

  • +Start from the OpenAgentSkill decision page.
  • +Use a narrow task with a clear expected result.
  • +Compare against manual work or one alternative skill.

What to verify

A skill is ready when it improves a repeatable loop without adding unclear permissions, brittle setup, or noisy output.

  • +Check repository freshness and quality score.
  • +Inspect generated code, tests, and browser checks.
  • +Document when the skill should and should not be used.

FAQ

Common questions

Do Codex skills need to be code-only?

No. Browser automation, GitHub workflow, document, and data-analysis skills can all help a coding agent complete work end to end.

How do I know a skill is safe enough?

There is no automatic guarantee. Use readiness signals as a filter, then review permissions, repository health, and output quality yourself.
