- `skill_id: string`

  Unique identifier for the skill.

  The format and length of IDs may change over time.

## Query parameters

- `limit: optional number`

  Number of results to return per page.

  Ranges from `1` to `1000`. Defaults to `20`.

  Read more about versioning and our version history [here](https://platform.claude.com/docs/en/api/versioning?sdk_languages=http).

- `"anthropic-workspace-id": optional string`

  Optional header to select the Workspace for this request. The value is a Workspace ID (for example, `wrkspc_011CZkZaBF1tNoB5wlCeusgy`).

  Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

## Returns

- `data: array of SkillVersion`

  List of skills.

  - `type: "skill_version"`

    Object type.

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

    default: skill_version

  - `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.

    format: date-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.

- `next_page: string or null`

  Token for fetching the next page of results.

  If `null`, there are no more results available. Pass this value to the `page` parameter in the next request to get the next page.

## Example

```bash
curl https://api.anthropic.com/v1/skills/$SKILL_ID/versions \
