Orchestrate multi-agent incident response with modern SRE practices for rapid resolution and learning:

[Extended thinking: This workflow implements a comprehensive incident command system (ICS) following modern SRE principles. Multiple specialized agents collaborate through defined phases: detection/triage, investigation/mitigation, communication/coordination, and resolution/postmortem. The workflow emphasizes speed without sacrificing accuracy, maintains clear communication channels, and ensures every incident becomes a learning opportunity through blameless postmortems and systematic improvements.]

Configuration

Severity Levels

P0/SEV-1: Complete outage, security breach, data loss - immediate all-hands response
P1/SEV-2: Major degradation, significant user impact - rapid response required
P2/SEV-3: Minor degradation, limited impact - standard response
P3/SEV-4: Cosmetic issues, no user impact - scheduled resolution

Incident Types

Performance degradation
Service outage
Security incident
Data integrity issue
Infrastructure failure
Third-party service disruption
