What is it for?
Use it after incidents, major launches, completed projects, recurring problems, or decisions that produced poor results.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

after-action-report scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

After-Action Report

Run a structured retrospective on a launch, incident, or completed project. Produce actionable lessons, not just a document.

This skill is for after-the-fact analysis. For active incident response, use incident-response. For planning launches, use launch-runbook.


When to use

  • After any incident (any severity)
  • After every major launch
  • At the end of a project (sprint retro, quarterly retro, project closeout)
  • When a recurring issue has happened enough times to demand investigation
  • When a decision didn't work out and the team wants to learn

When NOT to use

  • During an active incident (use incident-response)
  • For pre-launch planning (use launch-runbook)
  • For one-off bug fixes that don't merit broad analysis

Required inputs

  • The event being analyzed (incident, launch, project)
  • A timeline reconstructed from logs, chat, tickets
  • Participant accounts of what they observed and did
  • Outcomes and impact (what actually happened to users, the business)

The framework: blameless analysis

The most important principle: blameless. Without it, retrospectives produce hidden information and theatrical lessons rather than real ones.

What blameless means

  • Focus on systems, not individuals
  • Assume everyone made reasonable decisions given what they knew at the time
  • The question is "why was this decision reasonable to make?" not "who screwed up?"
  • Fixing the system means the next person in that situation succeeds where this person didn't

What blameless does not mean

  • No accountability (action items still have owners)
  • No hard truths (sometimes the system is broken in obvious ways)
  • No standards (some patterns of failure are individual, not systemic)
  • No discomfort (real reflection is uncomfortable)

The framework: 6 sections

A complete AAR covers six sections.

1. Summary

A 2 to 3 paragraph overview. Captures:

  • What happened
  • Impact (users, business, time)
  • Root cause (in plain language)
  • Top action items
