# Create Skill Version

`client.skills.versions.create(skillID, params, options?): SkillVersion`

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

Create Skill Version

## Parameters

- `skillID: string` (path parameter)

  Unique identifier for the skill.

  The format and length of IDs may change over time.

- `params: VersionCreateParams`

  - `files: Array<Uploadable>`

    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?: string` (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

- `interface SkillVersion`

  - `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.

## Example

```typescript
import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic({
  apiKey: process.env["ANTHROPIC_API_KEY"] // This is the default and can be omitted
});

const skillVersion = await client.skills.versions.create("skill_id", {
  files: [fs.createReadStream("path/to/file")]
});

console.log(skillVersion.id);
```
