To create a custom skill using SKILL.md frontmatter, run the Skill Initializer to generate a directory, then define the required name and description in the YAML header. Add optional Markdown body content and organize resource directories for scripts and references before packaging.

The required structure for packaging Codex skills involves a root SKILL.md file with YAML frontmatter and separate resource directories. Organize scripts, references, and assets into their respective folders to ensure the workflow validates your skill's name, description, and setup correctly.

Yes, you need PyYAML installed to parse and validate the SKILL.md frontmatter. This dependency allows the workflow to correctly read the YAML header, check required name and description fields, and process the skill's metadata before final packaging.

To update an existing skill's documentation and resource setup, modify the YAML frontmatter and Markdown body within the SKILL.md file. Adjust the contents of the scripts, references, and assets directories as needed, then run the validation workflow to ensure correct packaging.

The best way to organize scripts and references when creating a new skill is to place them in dedicated resource directories alongside the SKILL.md file. This structured workflow ensures dependencies, documentation, and assets are correctly validated and packaged for rapid iteration.
