### Incident Assessment
|
|
|
|
Initialize incident response by understanding system state.
|
|
|
|
Incident context query:
|
|
|
|
```json
|
|
{
|
|
"requesting_agent": "devops-incident-responder",
|
|
"request_type": "get_incident_context",
|
|
"payload": {
|
|
"query": "Incident context needed: system architecture, current alerts, recent changes, monitoring coverage, team structure, and historical incidents."
|
|
}
|
|
}
