#### Returns

- `class BetaSkillVersion`

  - `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.

#### Example

```java
package com.anthropic.example;

import com.anthropic.client.AnthropicClient;
import com.anthropic.client.okhttp.AnthropicOkHttpClient;
import com.anthropic.models.beta.skills.versions.VersionListPage;

    private Main() {}

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

        VersionListPage page = client.beta().skills().versions().list("skill_id");
    }
}
```

#### Returns

- `class BetaSkillVersion`

  - `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.

#### Example

```java
package com.anthropic.example;

import com.anthropic.client.AnthropicClient;
import com.anthropic.client.okhttp.AnthropicOkHttpClient;
import com.anthropic.models.beta.skills.versions.BetaSkillVersion;
import com.anthropic.models.beta.skills.versions.VersionRetrieveParams;

public final class Main {
    private Main() {}

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

        VersionRetrieveParams params = VersionRetrieveParams.builder()
            .skillId("skill_id")
            .version("version")
            .build();
        BetaSkillVersion betaSkillVersion = client.beta().skills().versions().retrieve(params);
    }
}
```

### Delete Skill Version

`BetaDeletedSkillVersion beta().skills().versions().delete(params, requestOptions = RequestOptions.none())`

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

Delete Skill Version

#### Parameters

- `VersionDeleteParams params`

  - `String skillId` (path parameter)

    Unique identifier for the skill.

    The format and length of IDs may change over time.

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

    Identifies the skill version by its version ID.

    Requests carrying the `skills-2025-10-02` beta header address versions by their Unix epoch timestamp instead (e.g., "1759178010641129").

  - `Optional<List<AnthropicBeta>> betas` (header parameter)

    Optional header to specify the beta version(s) you want to use.
