Get Skill Version

Parameters
version: string

Identifies the skill version: a version ID, or the literal latest for the skill's most recent version.

Requests carrying the skills-2025-10-02 beta header address versions by their Unix epoch timestamp instead (e.g., "1759178010641129").

params: VersionRetrieveParams { skill_id }
skill_id: string

Unique identifier for the skill.

The format and length of IDs may change over time.

Returns
SkillVersion { id, created_at, description, 3 more }
id: string

Unique identifier for this Skill Version. The id addresses the version in paths and pins it in references.

created_at: string

ISO 8601 timestamp of when the skill was created.

formatdate-time
description: string

Description of the skill version.

This is extracted from the SKILL.md file in the skill upload.

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.

type: "skill_version"
