After Action Report
Skill Verified ActiveRun a structured after-action review (postmortem, retrospective) on a launch, incident, or completed project to capture timeline, root cause analysis, contributing factors, and actionable lessons. Use this skill whenever the user wants to run a postmortem, retrospective, AAR, or after-action review on any past event. Triggers on after-action report, AAR, postmortem, retrospective, retro, post-incident review, what went well what didn't, lessons learned, blameless postmortem, root cause analysis, RCA, five whys. Also triggers when the user has just shipped something or just resolved an incident and wants to capture learnings.
To help teams systematically analyze past events to capture actionable lessons and improve future outcomes, fostering a blameless learning culture.
Features
- Structured AAR/postmortem generation
- Blameless analysis framework
- Timeline reconstruction and analysis
- Root cause analysis (Five Whys, causal chain)
- Identification of contributing factors and successes
- Generation of specific, owned, and dated action items
- Markdown document output
Use Cases
- Running postmortems after incidents
- Conducting retrospectives after launches or sprints
- Documenting lessons learned at project closeout
- Analyzing recurring issues to find systemic causes
Non-Goals
- Real-time incident response
- Pre-launch planning and runbooks
- Performing the actual root cause investigation (gathers data for it)

Incident Followup Audit
97Audits post-incident engineering follow-through after a sev or incident to verify whether the durable follow-up happened: regression tests, monitors, docs, runbooks, ownership updates, tickets, rollback learnings, and remaining backlog. Use when a user asks whether incident follow-up is complete, what still needs to be done after a postmortem, or how to close the engineering loop. Do NOT use for live incident response, root-cause analysis, or a generic bug hunt unrelated to an incident.
