How to Install Codex Skills

If you want to explore what exists, start with the Codex platform collection. This guide is for the next stage: picking a small starting set and validating fit before you roll anything out more widely.

Step 1: confirm the workflow before the install

Do not install by brand match alone. Decide whether your first use case is:

  • repository review
  • issue and PR handling
  • release preparation
  • browser-based validation

That choice determines which skills you should test first.

Step 2: choose a narrow starter set

A good Codex starter set is usually smaller than people expect. Begin with one repository workflow, one review workflow, and one adjacent automation workflow. On this site that usually means comparing Codex skills, GitHub skills, and Browser Automation skills.

Step 3: validate in a small repo first

Before broader rollout, verify:

  1. input assumptions
  2. output shape
  3. project conventions and review expectations

If your real question is how project conventions fit in, continue with the Codex AGENTS.md guide.
