pre-mortem-stress-test

pre-mortem-stress-test is a cursor rule for Cursor from GktuOktay/ai-skills. It costs 0 tokens per session (460 once invoked), scanned A, original, MIT.

A pre-release review method that imagines a system has already failed in production and investigates why. It examines traffic spikes, service failures, data corruption, and authorization bypasses.

In plain words
What is it for?
Use it to assess new databases, critical components, and system designs, then document likely failure scenarios and preventive measures.
Why use it?
It exposes weak points and single points of failure before a major architecture or infrastructure change goes live.

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

pre-mortem-stress-test 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 & System Stress Tester

Bu skill, büyük bir mimari değişiklik, yeni bir veritabanı veya kritik bir sistem bileşeni canlıya alınmadan önce çalışır. "Ön Otopsi" (Pre-Mortem) yöntemiyle sistemin gelecekte çökeceği senaryoyu simüle eder ve en zayıf halkanı tespit eder.


💥 Stres Testi Katmanları

  1. Yük ve Ölçeklenme Çöküşü (Traffic Spikes): Aniden 10x trafik gelirse sistem hangi noktada tıkanır? (Connection Pool, Rate Limit, CPU bottleneck).
  2. Bağımlılık İflası (Third-party Failure): Harici servis (Payment Gateway, Auth Provider, Mail API) 500 hatası verirse veya 5 saniye gecikirse sistem nasıl davranır?
  3. Veri Tutarsızlığı (Data Corruption): Veritabanı yazma anında sunucu kapanırsa veri tutarlı kalır mı? (Transaction rollback var mı?).
  4. Güvenlik & Yetkilendirme İhlali (Bypass): Saldırgan bu akışta yetki kontrolünü nasıl atlatabilir?

📊 Raporlama Formatı

💣 Sistem Ön Otopsi Raporu (Pre-Mortem Simulation)

  • 💀 Muhtemel Çöküş Noktası #1: [Senaryo ve Bileşen]
  • ⚠️ Zayıf Halka (Single Point of Failure): [Neden patlar?]
  • 🛡️ Önleyici Savunma (Mitigation Plan): [Nasıl engellenir?]

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.
