      For Skill Versions, this is always `"skill_version"`.

      upload's SKILL.md frontmatter `name` (or its enclosing directory). Every
      later upload must resolve to the same value. Also the top-level directory
      of the Skill's mounted files and the base name of a downloaded archive.

      Unique identifier for the skill.

      The format and length of IDs may change over time.
