FAQPage Schema
How do I create a new skill to extend Codex capabilities?

Create a skill by defining your concept in SKILL.md with proper frontmatter, then use the init_skill.py utility to scaffold the structure. Include metadata, workflows, and optional scripts or reference resources, then validate and package for distribution.

What should I include in a skill's frontmatter and metadata?

Skill frontmatter requires structured metadata including name, description, keywords, category, dependencies, and components. The SKILL.md file must validate against defined requirements to ensure functional and technical compliance for Codex integration.

How do I organize scripts, references, and assets in a skill?

Structure optional resource directories within your skill package: scripts for automation logic, references for domain knowledge documentation, and assets for supporting files. This modular organization enables reusable workflows and bundled distribution.

Can I update an existing skill to add new capabilities?

Yes, update existing skills by modifying SKILL.md frontmatter, adding new scripts or references, and re-validating against requirements. Changes integrate into Codex without creating duplicate skills, preserving version continuity.

What validation steps must a skill pass before distribution?

Skills must pass frontmatter validation against SKILL.md schema requirements and quick-validate checks. Successful validation confirms metadata structure, dependency declarations, and component organization meet Codex standards for packaging and deployment.

Do I need coding experience to build a skill?

Skills can range from procedural task workflows to reference guidelines, so coding is not required for all skill types. However, skills with integrated tool automation benefit from scripting knowledge and familiarity with the init_skill.py scaffolding process.
