# List Skill Versions

`client.Skills.Versions.List(ctx, skillID, params) (*PageCursor[SkillVersion], error)`

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

List Skill Versions

## Parameters

- `skillID string` (path parameter)

  Unique identifier for the skill.

  The format and length of IDs may change over time.

- `params SkillVersionListParams`

  - `Limit param.Opt[int64] Optional` (query parameter)

    Number of results to return per page.

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

    minimum: 1, maximum: 1000

  - `Page param.Opt[string] Optional` (query parameter)

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

  - `WorkspaceID param.Opt[string] Optional` (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

- `type SkillVersion`

  - `Type SkillVersion`

    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.

  - `CreatedAt Time`

    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.

  - `SkillID string`

    Unique identifier for the skill.

    The format and length of IDs may change over time.

package main

import (
	"context"
