# Create Skill Version

`$client->skills->versions->create(string skillID, list<FileParam | string> files, ?string workspaceID): 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.

- `files: list<FileParam | string>`

  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.

- `workspaceID?: optional 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

- `class SkillVersion`

  - `"skill_version" type`

    Object type.

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

  - `string id`

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

  - `\Datetime createdAt`

    ISO 8601 timestamp of when the skill was created.

  - `string description`

    Description of the skill version.

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

  - `string name`

    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.

  - `string skillID`

    Unique identifier for the skill.

    The format and length of IDs may change over time.

## Example

```php
<?php

require_once dirname(__DIR__) . '/vendor/autoload.php';

use Anthropic\Client;
use Anthropic\Core\FileParam;

$client = new Client(apiKey: 'my-anthropic-api-key');

$skillVersion = $client->skills->versions->create(
  'skill_id',
  files: [
    FileParam::fromString('Example data', filename: uniqid('file-upload-', true)),
  ],
  workspaceID: 'wrkspc_011CZkZaBF1tNoB5wlCeusgy',
);

var_dump($skillVersion);
```
