Skill profile
skill-creator
Codex's own bundled tool for authoring a new skill, invoked with $skill-creator.
What it actually does
- Bundled with Codex — asks what the workflow does and whether it needs scripts, then writes the SKILL.md and supporting files.
When to use it — and when not to
Use it when
- Writing a new Codex skill and want the scaffolding done for you rather than hand-authoring frontmatter.
Not for
- The `description` it produces is still worth editing yourself — a vague description won't trigger reliably.
Agent compatibility
- Codex
Confirmed means the skill’s own source or vendor states it works with that agent. Portable means it only reaches that agent through the shared SKILL.md format and a directory convention — real, but a weaker claim. An agent with no entry here isn’t known to be unsupported; it simply isn’t documented either way, so nothing is claimed. Full model on Agent Skills Compatibility.
Workflow fit
Idea → $skill-creator scaffold → edit the description for reliable triggering → use.
Evidence and provenance
Maintained by OpenAI (official). Primary source: openai/codex, last checked against this page’s claims on . This page summarizes and analyzes that source — it isn’t a copy of its SKILL.md or README, and installation happens at the source, not here.
