## Update a worker template

`$ handinger workers update`

**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`

  Worker id returned by the create worker endpoint.

- `--instructions: optional string`

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

- `--output-schema: optional map[unknown]`

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

- `--summary: optional string`

  Replaces the worker's short one-line summary.

- `--title: optional string`

  New display name for the worker.

- `--visibility: optional "public" or "private"`

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

### Returns

- `worker_template: object { id, createdAt, instructions, 8 more }`

  - `id: string`

  - `createdAt: string`

  - `instructions: string`

  - `organizationId: string`

  - `outputSchema: map[unknown]`

  - `summary: string`

  - `title: string`

  - `updatedAt: string`

  - `url: string`

    Web URL of the worker in the Handinger dashboard.

  - `userId: string`

  - `visibility: "public" or "private"`

    - `"public"`

    - `"private"`
