Repo-scoped Codex skills live in .agents/skills/.
Current skills:
file-to-skill: Convert a source file into a repo-scoped Codex skill.nothing-design: Nothing-inspired UI/UX design system.oop-refactoring: Practical OOP refactoring while preserving behavior.
Codex reads AGENTS.md automatically. Codex discovers skills from .agents/skills, then reads a skill's full SKILL.md only when that skill is selected.
