Pre-Mortem Panel

Q: How do I know the Pre-Mortem Panel output is good?

The skill verifies itself against its own quality checks: Five failure stories from genuinely different root causes; They're concrete narratives, not a vague risk list; Most-likely and most-lethal are distinguished; Early warning signs are named for the top failures.

🔵 Stable🕐 updated 2026-08-06 🔷 SkillSpec L3 pm-thinking

Imagine your plan already failed, then get five independent 'here's why it died' stories — before you commit. Use when asked to pre-mortem this, why might this fail, what are the risks before I start, or imagine this went wrong. Produces five distinct failure narratives (each from a different cause — execution, timing, people, external, wrong-assumption), the most likely and most lethal among them, the early warning signs of each, and the specific mitigations worth doing now — catching failures while they're still cheap to prevent.

What to give it

▸The plan or project — what you're about to commit to

▸The timeframe — when "did it work?" gets answered

▸What's at stake — so we prioritize lethal vs. minor failures

▸Known worries — anything already nagging you

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Five failure stories from genuinely different root causes

✓They're concrete narratives, not a vague risk list

✓Most-likely and most-lethal are distinguished

✓Early warning signs are named for the top failures

✓Specific, prioritized mitigations are proposed

⚠️ What it refuses to do

**One fear repeated** five times.

**Abstract risks** ("competition") instead of concrete stories.

**Treating likely and lethal as the same.**

**Warnings with no mitigations** to act on.
