SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Plans, launches, and decisions often carry hidden assumptions and blind spots that only surface after failure. This Skill applies the premortem method: it assumes your plan has already failed six months from now and works backward to expose every plausible reason why, before you commit. ## Core Features & Use Cases - Context-Gated Analysis: Gathers the minimum context (what it is, who it affects, what success looks like) before running, so failure scenarios are specific rather than generic. - Parallel Deep-Dive Agents: Launches one sub-agent per identified failure reason to produce failure stories, underlying assumptions, and early warning signs. - Actionable Synthesis: Delivers the most likely failure, the most dangerous failure, the hidden assumption, a concrete revised plan, and a pre-launch checklist. - Use Case: Before launching a $297 workshop, run a premortem to discover that your target buyers need spending approval, then pivot to a $47 pilot to validate the real audience. ## Quick Start Ask the assistant to run a premortem on your plan, for example by saying "premortem this: I'm launching a paid workshop for marketing directors next month."

FAQPage Schema
How do I run a premortem on a business plan?▼

State your plan and ask for a premortem, for example "premortem this launch plan." The skill gathers context about what it is, who it affects, and what success looks like, then generates failure reasons and a revised plan.

What is the difference between a premortem and a risk assessment?▼

A premortem assumes the plan has already failed and asks why, which triggers more specific and honest answers than asking what could go wrong. This prospective hindsight framing produces concrete failure narratives instead of vague risk lists.

When should I not use a premortem?▼

Avoid premortems for vague ideas without a concrete plan, questions with a single correct answer, draft feedback requests, or decisions already made and irreversible. It only helps when you can still change course.

What output files does the premortem generate?▼

Each session produces a self-contained HTML report with the synthesis and failure cards, plus a markdown transcript containing the gathered context, failure reasons, agent analyses, and full synthesis.

How does the premortem handle missing context about my plan?▼

It first scans the conversation and workspace files for existing context, then asks one focused question at a time until it knows what the plan is, who it affects, and what success looks like.
