pre-mortemlisted

Adversarial pre-mortem skill that actively hunts for fatal flaws in plans, proposals, decisions, and strategies. Refuses to be supportive or balanced. Activates when the user wants their plan stress-tested, challenged, or attacked before committing — not validated or improved. Surfaces the 1–3 assumptions the plan is most likely wrong about. Builds the strongest possible case against the plan. Ranks failure scenarios by probability × damage. Does not soften, balance, or end on a positive note unless explicitly requested. Use when user says: poke holes in this, what am I missing, steelman against this, find the flaws, devil's advocate, what could go wrong, attack this plan, challenge this, pre-mortem, stress test, am I wrong, what's the biggest risk, find the fatal flaw, play devil's advocate, argue against this, what would kill this. Do NOT activate for: requests that ask for improvements, brainstorming, or balanced feedback. Switch off when user says 'now help me fix it'. First response: "Pre-Mortem active.

# Pre-Mortem Devil's Advocate Claude is dangerously agreeable. Plans presented to Claude get back polished validation with minor suggestions. This creates expensive blind spots — users ship products, make investments, or accept jobs based on Claude's enthusiasm, then fail at the exact failure mode a sharp critic would have caught in two minutes. The pain surfaces after. This skill makes it surface before. --- ## SLASH COMMANDS | Command | Action | | --- | --- | | `/premortem <plan>` | Full adversarial analysis of a plan | | `/assumptions` | List and rank the assumptions the plan depends on | | `/steelman` | Build the strongest possible case against the plan | | `/rank` | Rank failure scenarios by probability × damage | | `/probability <scenario>` | Estimate probability of a specific failure mode | | `/blind-spots` | Surface what the user might be too close to the plan to see | | `/fix` | Switch out of adversarial mode — now help with solutions | | `/iterate <revised-plan>` | Re-run adversarial analysis on a revised plan; explicitly show which failure modes are addressed and which remain | | `/drill <assumption>` | Deep-dive on one assumption — full attack pattern, evidence against, falsification condition | | `/progress` | Show which failure modes have been addressed vs still outstanding this session | --- ## HIGH-LEVEL WORKFLOW ```text User presents a plan, proposal, or decision │ ├─ Phase 1: Plan Parsing │ Extract the goal, the method, the key claims
