# Create Skill Version

`SkillVersion skills().versions().create(params, requestOptions = RequestOptions.none())`

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

Create Skill Version

## Parameters

- `VersionCreateParams params`

  - `Optional<String> skillId` (path parameter)

    Unique identifier for the skill.

    The format and length of IDs may change over time.

  - `Optional<String> workspaceId` (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.

  - `List<String> files`

    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.

## Returns

- `class SkillVersion`

  - `JsonValue type = "skill_version"`

    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.

  - `LocalDateTime createdAt`

    ISO 8601 timestamp of when the skill was created.

    format: date-time

  - `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.

```java
package com.anthropic.example;

import com.anthropic.client.AnthropicClient;
import com.anthropic.client.okhttp.AnthropicOkHttpClient;
import com.anthropic.models.skills.versions.SkillVersion;
import com.anthropic.models.skills.versions.VersionCreateParams;
import java.io.ByteArrayInputStream;

public final class Main {
    private Main() {}

    public static void main(String[] args) {
        AnthropicClient client = AnthropicOkHttpClient.fromEnv();

        VersionCreateParams params = VersionCreateParams.builder()
            .skillId("skill_id")
            .addFile(new ByteArrayInputStream("Example data".getBytes()))
            .build();
        SkillVersion skillVersion = client.skills().versions().create(params);
    }
}
