# List Skill Versions

`VersionListPage Skills.Versions.List(parameters, cancellationToken = default)`

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

List Skill Versions

## Parameters

- `VersionListParams parameters`

  - `required string skillID` (path parameter)

    Unique identifier for the skill.

    The format and length of IDs may change over time.

  - `long? limit` (query parameter)

    Number of results to return per page.

    Ranges from `1` to `1000`. Defaults to `20`.

    minimum: 1, maximum: 1000

  - `string? page` (query parameter)

    Optionally set to the `next_page` token from the previous response.

  - `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.

## Returns

- `class SkillVersion`

  - `JsonElement Type = "skill_version"`

    Object type.

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

  - `required string ID`

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

  - `required DateTimeOffset CreatedAt`

    ISO 8601 timestamp of when the skill was created.

    format: date-time

  - `required string Description`

    Description of the skill version.

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

  - `required 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.

  - `required string SkillID`

    Unique identifier for the skill.

    The format and length of IDs may change over time.

```csharp
using System;
using Anthropic.Models.Skills.Versions;

VersionListParams parameters = new() { SkillID = "skill_id" };
