重跑任务实例
AI agents call RerunTaskInstances to retrieve information from Alibabacloud Dataworks without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
Ids | array | — | 任务实例ID列表 |
Comment | string | — | 备注信息 |
Parameters from the server's own tool schema.
