Agent Skills for Codex
Codex works from the same SKILL.md format: a folder of instructions, templates and checks your agent loads for a specific kind of work. SkillU skills are written to that shared format, with automation skills leading the catalog.

FAQ
Do all SkillU skills work in Codex?
The catalog targets the shared SKILL.md format Codex reads. Each skill page lists the agents it supports, and anything a skill needs (an account, a key, a connected app) is stated on its page before you install it.
How do I install a SkillU skill in Codex?
Place the Skill folder in the skills directory Codex documents for your setup. Invoke the Skill by name inside Codex, or describe the outcome you want in plain words. Check the result against the Skill page example, then iterate in the same session.
Are SkillU skills free?
Skills marked Free are free. Premium skills are included in a SkillU plan — Monthly, Yearly or Founding Lifetime — and free skills remain a good way to feel the format before upgrading.
