    paths and pins it in references.

  - `name: string`

    The Skill's immutable kebab-case slug, set at creation from the first
    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.

  - `skill_id: string`

    Unique identifier for the skill.

    The format and length of IDs may change over time.
