# CognitionAcp.AgentStoppedNotification

> Notification payload when the agent stops.

Sent as a custom JSON-RPC notification with method \[`AGENT_STOPPED_METHOD`].
This captures the full stop semantics beyond what `PromptResponse.stopReason`
provides — for example, distinguishing between restart, tool rejection, and
auth-required stops.

```typescript
type AgentStoppedNotification = void
```
