# incident-response-incident-response

> Use when working with incident response incident response

> **Platform Note:** This skill was designed for multi-agent execution. In Copilot, treat sub-agent instructions as sequential steps within a single agent context or use `runSubagent` tool when available.

## Use this skill when

- Working on incident response incident response tasks or workflows
- Needing guidance, best practices, or checklists for incident response incident response

## Do not use this skill when

- The task is unrelated to incident response incident response
- You need a different domain or tool outside this scope

## Instructions

- Clarify goals, constraints, and required inputs.
- Apply relevant best practices and validate outcomes.
- Provide actionable steps and verification.

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
