aar

A structured review of an important event, such as a project or incident. It compares what was expected with what actually happened, then records lessons and next steps.

In plain words
What is it for?
Use it after launches, outages, presentations, or other significant events to document timelines, explain differences, and agree on improvements.
Why use it?
It turns a vague discussion into a fact-based review and helps teams learn without blaming individuals.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

aar 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

After-Action Review

Conduct a structured debrief to extract learning from any significant event or experience.

Instructions

Work through the four core questions honestly and specifically. Focus on events and systems, not blaming individuals.

Output Format

Event: What are we reviewing? Date: When did it happen? Participants: Who was involved?


1. What Was Expected?

Before the event, what did we think would happen?

Goals/Objectives

  • [What were we trying to achieve?]

Plan

  • [What was the plan to achieve it?]

Success Criteria

  • [How would we know if we succeeded?]

Assumptions

  • [What did we assume would be true?]

2. What Actually Happened?

Facts only—what occurred, not why

Timeline

Time Event
[When] [What happened]
[When] [What happened]
[When] [What happened]

Outcomes

  • [What results did we get?]

Compared to Expected

Expected Actual Gap
[expectation] [reality] [+/-]

3. Why the Difference?

Analysis of the gap between expected and actual

What Went Well (sustain these)

Success Contributing Factors
[what worked] [why it worked]

What Didn't Go Well (improve these)

Problem Root Cause
[what failed] [why it failed]

Surprises

  • [Things we didn't anticipate]

Assumptions Tested

Assumption Validated? Learning
[assumption] Yes/No/Partial [what we learned]

4. What Do We Do Next?

Specific actions to sustain or improve

Sustain (keep doing these)

Action Owner How to Protect It
[what to continue] [who] [mechanism]

Improve (change these)

Action Owner By When
[what to change] [who] [deadline]

Stop (eliminate these)

Action Owner Replacement

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

aar is a command published in the GitHub repository neurofoo/agent-skills (111 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 659 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
