What problem does it solve? Creating a well-structured skill for Codex requires knowing the SKILL.md frontmatter format, naming rules, resource organization, and validation requirements, which is easy to get wrong without guidance. ## Core Features & Use Cases - Skill Scaffolding: Generate a complete skill directory with a templated SKILL.md, agents/openai.yaml UI metadata, and optional scripts, references, and assets folders using init_skill.py. - Validation: Check frontmatter format, required fields, naming rules, and description constraints with quick_validate.py before publishing. - Authoring Guidance: Apply progressive disclosure principles, naming conventions, and a six-step creation workflow covering planning, initialization, editing, validation, and forward-testing. - Use Case: When you want to teach Codex a repeatable workflow like rotating PDFs, use this skill to scaffold a pdf-editor skill, add a rotation script, write triggering instructions, and validate the result. ## Quick Start Use the skill-creator skill to create a new skill named pdf-editor in my Codex skills directory with a scripts folder.
