What problem does it solve? Writing a well-structured Codex skill requires knowing the SKILL.md frontmatter rules, naming conventions, progressive disclosure patterns, and validation requirements, which are easy to get wrong without guidance. ## Core Features & Use Cases - Skill Scaffolding: Initialize a new skill directory with a SKILL.md template, agents/openai.yaml UI metadata, and optional scripts, references, and assets folders via init_skill.py. - Authoring Guidance: Apply core principles for scoped instructions, discriminating descriptions, and progressive disclosure across entrypoint and reference files. - Validation: Check frontmatter, naming rules, and unfinished TODO placeholders with quick_validate.py before publishing a skill. - Use Case: When you want to package a repeatable workflow as a reusable Codex skill, use this Skill to scaffold the folder, write the instructions, generate UI metadata, and validate the result. ## Quick Start Use the skill-creator skill to create a new skill named pdf-rotator in my skills directory with a scripts folder and validate it.
