DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

## Delete Skill Version

**delete** `/v1/skills/{skill_id}/versions/{version}`

Delete Skill Version

### Path Parameters

- `skill_id: string`

  Unique identifier for the skill.

  The format and length of IDs may change over time.

- `version: string`

  Identifies the skill version: a version ID, or — where the endpoint accepts it — 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").

### Returns

- `DeletedSkillVersion object { id, type }`

  - `id: string`

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

  - `type: "skill_version_deleted"`

    Deleted object type.

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

    - `"skill_version_deleted"`

### Example

```http
curl https://api.anthropic.com/v1/skills/$SKILL_ID/versions/$VERSION \
    -X DELETE \
    -H 'anthropic-version: 2023-06-01' \
    -H "X-Api-Key: $ANTHROPIC_API_KEY"
```

#### Response

```json
{
  "id": "id",
  "type": "skill_version_deleted"
}
```
