Skill Creator
Use this skill to create compact, usable Codex skills.
Required Structure
Every skill folder must include:
SKILL.md- YAML frontmatter with only
nameanddescription - Clear instructions in the body
Recommended UI metadata:
agents/openai.yamldisplay_nameshort_descriptiondefault_prompt
Workflow
- Normalize the skill name to lowercase hyphen-case.
- Write a trigger-focused description that says when to use the skill.
- Keep the body concise and procedural.
- Add scripts, references, or assets only when they directly support repeated use.
- Validate that every required file exists and the name matches the folder.
Quality Bar
- Do not add extra README-style documentation unless the user asks.
- Keep instructions useful for another Codex instance, not for a human installation guide.
- Prefer reusable scripts for fragile repeatable operations.
- Keep references one level away from
SKILL.mdand load them only when needed.
