# AgentStopCause

> Why the agent stopped — more granular than ACP's .

Why the agent stopped — more granular than ACP's `stopReason`. Mirrors the
ACP schema's `AgentStopCause`.

```typescript
const AgentStopCause: { AuthRequired: "auth_required"; Cancelled: "cancelled"; Complete: "complete"; ContentFilter: "content_filter"; Error: "error"; Interrupted: "interrupted"; MaxTurnRequests: "max_turn_requests"; OutputTruncated: "output_truncated"; QuotaExhausted: "quota_exhausted"; Shutdown: "shutdown"; ToolRejected: "tool_rejected" }
```
