## Evidence notes (from repository text)
- README summary paragraph: DAT 致力于解决企业数据查询的最后一公里问题——让业务人员能够用自然语言直接与数据库对话，无需编写复杂的 SQL 查询。通过预建模的语义层，DAT 确保 AI 不仅能自信地表达，更能正确地表达。
- DAT 的核心驱动力，并非完全源于大语言模型自身的又一次智力爆炸，而是源于我们为它设计的 Askdata Agent 工作流程。
- - 2、DAT 它不是一个 platform ，而是一个 `framework`；二次开发者可以基于 `dat-sdk` 开发自己的Web UI，可以是web ide、拖拉拽的workflow、列表等交互方式；或将其对外提供 `OpenAPI` 或 `MCP` 的服务。
- 如果您使用的是支持 **MCP (Model Context Protocol)** 的 Agent（如 Claude Desktop、Cline 等），可以 [启动DAT的MCP服务](#-mcp-服务) 将智能问数能力集成到这些 Agent 中。

## worker.md contract (derived starter)
Purpose: Execute one orchestrated agent task as a bounded worker step.

### Input schema
```json
{
  "type": "object",
  "additionalProperties": false,
  "required": [
    "run_id",
    "task",
    "context"
  ],
  "properties": {
    "run_id": {
      "type": "string"
    },
    "task": {
      "type": "string"
    },
    "context": {
      "type": "object"
    }
  }
}
```

### Output schema
```json
{
  "type": "object",
  "additionalProperties": false,
  "required": [
    "run_id",
    "status",
    "result"
  ],
  "properties": {
    "run_id": {
      "type": "string"
    },
    "status": {
      "type": "string",
      "enum": [
        "ok",
        "retryable_error",
        "invalid_request",
        "invalid_output"
      ]
    },
    "result": {
      "type": "object"
    }
  }
}
```

### Constraints
- timeout_seconds: 30
- max_attempts: 2
- idempotency_key: run_id
- status_enum: [ok, retryable_error, invalid_request, invalid_output]
- notes: adapt to concrete APIs/classes documented in this repository before production use

## How this should be used
1. Treat this file as a repo-derived starter profile, not a claim of an official repository API contract.
2. Replace schemas with exact interfaces from code/docs you adopt.
3. Keep execution bounded and auditable using worker protocol constraints.

How to use#

• Save this as a worker spec file (for example: dat-my-task.worker.md).
• Replace the input/output schemas and purpose with your real bounded task.
• Enforce schema validation + timeout + retry policy in your runtime before production use.
