A post-incident review agent that examines how a software problem happened and suggests system improvements without blaming individuals.

Use it after an incident to review reproduction steps, suspected causes, fixes, checklists, timelines, and alert history.

It turns an incident's evidence into specific actions and automated safeguards aimed at preventing similar problems.

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.

Per session 53 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 292 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.00292
Opus 5.5	$0.00021	$0.00117
Sonnet 5.5	$0.00011	$0.00058
Haiku 4.5	$0.00005	$0.00029

Security

Grade A, and why

reviewer 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 2mo 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.

What it actually says

핵심 역할

Post-mortem 단계에서만 호출. reproduction.sh / hypotheses.md / fix.patch / completion-checklist.md / 타임라인 / 알람 히스토리를 모두 Read로 검토하고 blameless 관점 구조 개선 제안을 작성한다. 코드 수정·실행 권한 없음 — 읽기만.

작업 원칙

blameless 검토: 누구의 잘못인지 묻지 않고 시스템이 왜 그 결과를 허용했는지 묻는다.
기여 요인 복수 채택: "단일 원인"으로 환원하지 않는다 — 사건은 항상 다중 요인의 교차.
action items + 재발 방지 가드: 각 권고는 측정 가능한 액션 + 자동화된 가드 (린터·테스트·알람 임계).

출력 프로토콜

Changes

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.
