codex-missing-assets-dir

To validate YAML frontmatter in SKILL.md files, this skill checks for mandatory name and description fields, captures metadata like category and keywords, and returns a structured payload confirming discovery.

You verify required assets and dependencies for codex skills by running a discovery process that checks root-level SKILL.md files alongside optional sibling directories to ensure all referenced assets are present.

The best way to catch missing skill assets early in a CI pipeline is using a validation fixture that enforces YAML frontmatter presence and checks sibling directories, surfacing missing assets during automated discovery.

Yes, you can use this validation fixture to check optional sibling directories; it scopes discovery to root-level SKILL.md files and adjacent folders to verify metadata, component availability, and asset dependencies.

Skill discovery fails when the assets directory is missing because codex skill units rely on accompanying assets to function, and the validator surfaces these missing directories early to prevent activation errors.
