## Update a worker template

`workers.update(worker_id, **kwargs) -> WorkerTemplate`

**patch** `/api/workers/{workerId}`

Update a worker's instructions, title, summary, visibility, or output schema. Only the fields you send are changed; omitted fields keep their current values. Only the worker creator can update a worker.

### Parameters

- `worker_id: String`

- `instructions: String`

  Replaces the persistent system prompt. Subsequent tasks pick up the new instructions immediately; in-flight tasks keep using the previous version.

- `output_schema: Hash[Symbol, untyped]`

  Replace the worker's structured output schema. Pass `null` to clear it and return to free-form text responses.

- `summary: String`

  Replaces the worker's short one-line summary.

- `title: String`

  New display name for the worker.

- `visibility: :public | :private`

  Change visibility between `public` (any org member can run tasks) and `private` (only invited members).

  - `:public`

  - `:private`

### Returns

- `class WorkerTemplate`

  - `id: String`

  - `created_at: String`

  - `instructions: String`

  - `organization_id: String`

  - `output_schema: Hash[Symbol, untyped]`

  - `summary: String`

  - `title: String`

  - `updated_at: String`

  - `url: String`

    Web URL of the worker in the Handinger dashboard.

  - `user_id: String`

  - `visibility: :public | :private`

    - `:public`

    - `:private`
