Custom skills for Codex.

This option can either be:

  • An attribute set defining skills
  • A path to a directory containing multiple skill folders

If an attribute set is used, the attribute name becomes the skill directory name, and the value is either:

  • Inline content as a string (creates skills/<name>/SKILL.md)
  • A path to a file (creates skills/<name>/SKILL.md)
  • A path to a directory (creates skills/<name>/ with all files)

If a path is used, it is expected to contain one folder per skill name, each containing a SKILL.md. The directory is symlinked to skills/.
