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.

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 | $0.00035 | $0.00805 |
| Opus 5 | $0.00017 | $0.00402 |
| Sonnet 5 | $0.00007 | $0.00161 |
| Haiku 4.5 | $0.00003 | $0.00081 |
Grade A, and why
premortem 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 8d 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
Pre-Mortem Skill
Tier-2 (v1.1.x slot). Gary Klein 의 pre-mortem 기법. 출시 전 마지막 sanity check.
진행 흐름
1. Time Travel
"6개월 후. 이 프로젝트는 실패 했다. 사용자는 떠났고, OKR 미달."
2. 실패 원인 brainstorm (≥10)
가능한 모든 실패 시나리오를 나열. positive thinking 자제, 비관적으로.
failure_modes:
- id: f1
scenario: "사용자가 첫 사용 후 다시 안 옴"
likelihood: high | medium | low
impact: critical | major | minor
detection_lag: "..." # 얼마나 늦게 알게 되나
early_signal: "..." # 어떤 지표가 미리 알려주나
mitigation:
- "..."
3. 우선순위 매트릭스
- (likelihood × impact) 곱으로 정렬
- top 5 risk → 사전 mitigation 필수
4. Launch Checklist 도출
## Launch Checklist — {{project}}

- [ ] security audit (auth/data 변경 시)
- [ ] product-designer 검토 (정책 영향 시)
- [ ] data-analyst instrumentation 검증
- [ ] (premortem risks → 대응 완료 확인) × 5
### Launch (T-0)
- [ ] rollback plan 명시

HARD GATE
- [ ] failure modes ≥ 10 brainstorm
- [ ] top 5 risk 모두 mitigation 완료
- [ ] launch checklist 모든 항목 ✅
- [ ] release notes 작성 완료
- [ ] rollback plan 명시 + 실험
Anti-Sycophancy
비관적 사고 강제:
- ❌ "출시 준비가 잘 되었습니다"
- ✅ "5 risk 중 3건 mitigated. risk #2 (적용 시 latency +200ms) 는 monitoring 만 완료. monitoring 발동 임계값 명시 필요."

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.
- 8d ago First seen · 116 lines · 35 tokens per session scan A f4d0436bf966
premortem is a skill published in the GitHub repository Adelie-Squad/solosquad (19 stars, last pushed 17d ago), licensed MIT. It adds 35 tokens to every session and 805 once invoked, about $0.0002 per session on Opus 5. 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.
