Installation guide
A step-by-step workflow for adding install-ready skills to a Codex-style agent setup while keeping validation, permissions, and rollback in mind.
Decision prompt
I want to install an Agent Skill in Codex, test it on a real repository task, and decide whether it belongs in my workflow.

Use the recommendation API with the task prompt from this guide.
Install the top candidate only after reading the risks and proof points.
Ask Codex to implement, verify, and explain the change before adding the skill to defaults.
Evaluation notes
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.
A skill is ready when it improves a repeatable loop without adding unclear permissions, brittle setup, or noisy output.
FAQ
No. Browser automation, GitHub workflow, document, and data-analysis skills can all help a coding agent complete work end to end.
There is no automatic guarantee. Use readiness signals as a filter, then review permissions, repository health, and output quality yourself.
