# Responding To Security Incidents
## Overview
This skill provides automated assistance for the described functionality.
## Prerequisites
Before using this skill, ensure:
- Access to system and application logs in {baseDir}/logs/
- Network traffic captures or SIEM data available
- Incident response team contact information
- Backup systems operational and accessible
- Write permissions for incident documentation in {baseDir}/incidents/
- Communication channels established for stakeholder updates
## Instructions
1. Triage the incident and scope affected systems/data.
2. Preserve evidence (logs, snapshots, network captures) before making changes.
3. Contain the blast radius and eradicate root cause.
4. Recover safely and document follow-ups (AAR + backlog).
See `{baseDir}/references/implementation.md` for detailed implementation guide.
## Output
The skill produces:
**Primary Output**: Incident response playbook saved to {baseDir}/incidents/incident-YYYYMMDD-HHMM.md
**Playbook Structure**:
```
