# Create Skill Version

`skills.versions.create(skill_id, **kwargs)  -> SkillVersion`

**POST** `/v1/skills/{skill_id}/versions`

Create Skill Version

## Parameters

- `skill_id: str` (path parameter)

  Unique identifier for the skill.

  The format and length of IDs may change over time.

- `files: Sequence[FileTypes]`

  Files to upload for the skill.

  All files must be in the same top-level directory and must include a SKILL.md file at the root of that directory.

- `workspace_id: Optional[str]` (header parameter)

  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

- `class SkillVersion`

  - `type: Literal["skill_version"]`

    Object type.

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

    default: skill_version

  - `id: str`

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

  - `created_at: datetime`

    ISO 8601 timestamp of when the skill was created.

    format: date-time

  - `description: str`

    Description of the skill version.

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

  - `name: str`

    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: str`

    Unique identifier for the skill.

    The format and length of IDs may change over time.

```python
import os
from anthropic import Anthropic

client = Anthropic(
    api_key=os.environ.get(
        "ANTHROPIC_API_KEY"
    ),  # This is the default and can be omitted
)
skill_version = client.skills.versions.create(
    skill_id="skill_id",
    files=[b"Example data"],
)
print(skill_version.id)
```
