| description | Use when actively responding to production incidents, diagnosing critical service failures, or conducting incident postmortems to implement permanent fixes and preventative measures. Specifically:\n\n<example>\nContext: A critical database service has gone down, causing customer-facing API timeouts. The on-call engineer needs immediate help triaging impact and determining next steps.\nuser: "We're getting spiked error rates on our API - database connection timeouts appearing 2 minutes ago. I need to triage this quickly."\nassistant: "I'll help diagnose this immediately. Let me query the system architecture and recent changes, check database logs for connection issues, identify affected services, assess customer impact, and determine if rollback or failover is needed. Do we have a distributed trace showing the failure pattern?"\n<commentary>\nUse the devops-incident-responder when actively in incident response mode needing rapid diagnosis and decision support during an active production incident.\n</commentary>\n</example>\n\n<example>\nContext: An incident occurred 12 hours ago and was resolved, but the team needs to conduct a thorough postmortem to prevent recurrence.\nuser: "We had a deployment issue this morning that caused 30 minutes of downtime. Can you help us document the timeline and identify what we could have prevented?"\nassistant: "I'll help conduct the postmortem. Let me gather the timeline from logs, analyze the root cause through the incident sequence, identify preventative measures we could have implemented, and create action items for our runbook and monitoring gaps. I'll structure this in a blameless format focused on system improvements."\n<commentary>\nUse the devops-incident-responder for post-incident analysis and creating improvements to prevent similar failures, focusing on root cause analysis and process refinement.\n</commentary>\n</example>\n\n<example>\nContext: The engineering team wants to improve their incident detection and response capabilities to reduce MTTR and runbook coverage gaps.\nuser: "Our MTTR is currently 45 minutes and we only have runbooks for 60% of critical scenarios. What should we focus on first?"\nassistant: "I'll assess your current incident readiness. Let me review your monitoring coverage, alert effectiveness, existing runbooks, team procedures, and historical incidents. I'll identify gaps in detection speed, recommend alert optimization, create runbook templates for missing procedures, and suggest automation opportunities to reduce MTTR."\n<commentary>\nUse the devops-incident-responder when building or improving incident response infrastructure, implementing runbooks, alert optimization, and automation systems to reduce incident impact.\n</commentary>\n</example> |
