Agent Skills: Incident Commander

Incident Commander

Classify incident severity, reconstruct timelines from heterogeneous event sources, and generate structured post-incident reviews with root cause analysis and action items. Codifies PagerDuty, Google SRE, and Atlassian incident-management practices into severity scoring, escalation matrices, communication templates, RCA frameworks, and SLA/error-budget tracking.

Core Capabilities

• Severity classification — multi-dimensional scoring (revenue, user scope, data/security risk, service criticality, blast radius) into SEV-1 to SEV-4 with confidence and escalation paths.
• Timeline reconstruction — chronological timelines from logs, alerts, Slack, and deploy events with phase detection and gap analysis.
• Post-incident review — PIRs with 5 Whys, Fishbone, Timeline, or Bow Tie RCA plus categorized action items (owner, priority, deadline).
• Postmortem quality — coverage-gap detection, action-item quality scoring, MTTD/MTTR benchmarking.
• Communication & escalation — severity-specific internal/executive/customer/status-page templates; technical (L1-L4) and business escalation matrices with time-based triggers.
• SLA / error-budget tracking — SLI/SLO/SLA hierarchy, error budgets, burn-rate alerting, and breach handling.

When to Use

• Handling an active incident — classify severity, establish command, mitigate, communicate.
• Running a post-incident review — reconstruct timeline, perform RCA, assign action items.
• Managing escalation — apply technical and business escalation paths by severity and elapsed time.
• Building or auditing response playbooks, comms templates, or SLA/error-budget policy.

Clarify First

Before producing the artifact, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• [ ] Task & deliverable — classify severity, reconstruct a timeline, or generate a PIR/postmortem (selects severity_classifier.py vs timeline_reconstructor.py vs pir_generator.py/postmortem_generator.py)
• [ ] Incident input data — the incident/events JSON with severity dimensions (revenue, user scope, data/security risk, blast radius) (the input the scripts parse)
• [ ] RCA method — 5 Whys, Fishbone, Timeline, or Bow Tie (sets pir_generator.py --rca-method and the postmortem structure)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Scope & Limitations

Covers: severity classification, timeline reconstruction, PIR/postmortem generation, RCA frameworks, escalation matrices, communication templates, and SLA/error-budget tracking. Tools are deterministic stdlib Python (no ML/LLM calls), accepting JSON input and emitting text/JSON/markdown.

Does NOT cover: live monitoring/alerting infrastructure (feeds in from senior-devops), security forensics (see senior-secops), or deployment/rollback execution (see release-orchestrator).

Integration Points

| Skill | Integration | |-------|-------------| | senior-devops | Monitoring alerts feed timeline; runbook templates inform playbooks | | senior-secops | Security incidents auto-escalate to SEV-1; breach indicators trigger SecOps response | | release-orchestrator | Deployment events feed timeline; rollback data informs release gates | | senior-architect | Architectural root causes escalate to architecture review | | code-reviewer | PIR action items route to code review workflows |
