Questions
Codex and skills.
Do Claude skills work in Codex?
Often. A skill is a folder of instructions and scripts in the open SKILL.md format, which Codex reads. A skill that depends on tools only one agent provides will not carry over, so read the skill's source before you rely on it.
How do I install a skill in Codex?
Each skill page has an install command. Run it in a terminal, then start a new Codex session so the skill is picked up.
What is the difference between a skill and an instructions file such as AGENTS.md?
An instructions file is loaded in every session and describes the project. A skill is loaded only when a task calls for it, so it can be long and specific without costing context on every turn.
