What Incident Response does
The Incident Response skill is designed to assist teams in managing incidents from detection through to postmortem analysis. It provides a structured workflow that guides users through the critical phases of incident management: triage, communication, mitigation, and postmortem. By using this skill, teams can effectively assess the severity of incidents, communicate updates to stakeholders, and document the entire process for future reference.
When an incident occurs, users can initiate the workflow by triggering commands such as 'we have an incident' or 'production is down'. The skill allows for the creation of new incidents, status updates, and the generation of postmortem documents based on the incident data collected. This structured approach ensures that all necessary steps are followed, helping teams to respond promptly and effectively.
The skill is particularly useful for development and operations teams who need to manage incidents in a systematic way. By providing templates for status updates and postmortems, it reduces the cognitive load on team members during high-pressure situations. The emphasis on blameless postmortems encourages a culture of learning and improvement, focusing on systems and processes rather than individual mistakes.
Overall, the Incident Response skill is a valuable tool for any organization that needs to handle incidents efficiently, ensuring that all relevant information is captured and communicated throughout the incident lifecycle.
When to use it
Use this skill when an incident occurs, such as a service outage or a significant bug, to ensure a systematic response and documentation process.
When not to use it
This skill may not be suitable for non-technical incidents or situations where a more informal response is adequate.
What you can build with it
Service Outage Management
When a critical service goes down, trigger the skill to assess severity and communicate updates to stakeholders.
Postmortem Analysis
After resolving an incident, use the skill to generate a blameless postmortem document that captures lessons learned.
Status Updates During an Incident
During an ongoing incident, utilize the skill to draft clear and factual status updates for internal and external communication.
How to install Incident Response

How It Works
┌─────────────────────────────────────────────────────────────────┐
│ INCIDENT RESPONSE │
├─────────────────────────────────────────────────────────────────┤
│ Phase 1: TRIAGE │
│ ✓ Assess severity (SEV1-4) │
│ ✓ Identify affected systems and users │
│ ✓ Assign roles (IC, comms, responders) │
│ │
│ Phase 2: COMMUNICATE │
│ ✓ Draft internal status update │
│ ✓ Draft customer communication (if needed) │
│ ✓ Set up war room and cadence │
│ │
│ Phase 3: MITIGATE │
│ ✓ Document mitigation steps taken │
│ ✓ Track timeline of events │
│ ✓ Confirm resolution │
│ │
│ Phase 4: POSTMORTEM │
│ ✓ Blameless postmortem document │
│ ✓ Timeline reconstruction │
│ ✓ Root cause analysis (5 whys) │
│ ✓ Action items with owners │

Severity Classification
| Level | Criteria | Response Time |
|---|---|---|
| SEV1 | Service down, all users affected | Immediate, all-hands |
| SEV2 | Major feature degraded, many users affected | Within 15 min |
| SEV3 | Minor feature issue, some users affected | Within 1 hour |
| SEV4 | Cosmetic or low-impact issue | Next business day |
Communication Guidance
Provide clear, factual updates at regular cadence. Include: what's happening, who's affected, what we're doing, when the next update is.

If Connectors Available
If ~~monitoring is connected:
- Pull alert details and metrics
- Show graphs of affected metrics
If ~~incident management is connected:
- Create or update incident in PagerDuty/Opsgenie
- Page on-call responders
If ~~chat is connected:
- Post status updates to incident channel
- Create war room channel
Tips
- Start writing immediately — Don't wait for complete information. Update as you learn more.
- Keep updates factual — What we know, what we've done, what's next. No speculation.
- Postmortems are blameless — Focus on systems and processes, not individuals.
