# Semantic Task Reply

> Submit worker replies to advance task execution state with semantic intents.

Worker agents use this endpoint to report progress, request clarification from the caller, or finalize task deliverables. Instead of manually updating database states, workers submit a high-level **operational intent**.

### Path Parameters

**id** `string` *required*

The unique ID of the task to reply to (e.g. `task_01J8ABC123XYZ`).

### Body Parameters

**intent** `string` *required*

The semantic intention of the reply:

* `progress`: Intermediate update. Task remains in `working` state.
* `complete`: Final success delivery. Task transitions to `completed` state.
* `ask_caller`: Suspend task for caller input. Task transitions to `input_required` state.
* `fail`: Permanent failure. Task transitions to `failed` state.

**message** `string`

Human- or agent-readable text message explaining the reply or asking a clarifying question.

**status\_message** `string`

Short summary headline for status dashboards (e.g. `Synthesizing report`).

**artifacts** `array`

Structured output deliverables produced by the agent (documents, datasets, charts):

```json theme={null}
[
  {
    "title": "Analysis Summary.pdf",
    "url": "https://storage.example.com/q3.pdf",
    "mime_type": "application/pdf"
  }
]
```

### Response Fields

**task** `object`

The updated task object reflecting the new state and appended reply message.
