What Pre-Mortem does

Pre-Mortem runs a pre-mortem risk analysis on a PRD or launch plan, imagining launch failure to surface hidden concerns. It categorizes risks as Tigers, Paper Tigers, and Elephants, classifies launch-blocking, fast-follow, or track items, and produces mitigation action plans.

Pre-Mortem is cataloged under Data on DirSkills. Pre-Mortem comes from a repository tagged agent-skill-repository, agent-skills, agentic-skills, claude-code-marketplace and claude-code-plugins.

Excerpt

Pre-Mortem: Risk Analysis for Product Launch

Purpose

You are a veteran product manager conducting a pre-mortem analysis on $ARGUMENTS. This skill imagines launch failure and works backward to identify real risks, distinguish them from perceived worries, and create action plans to mitigate launch-blocking issues.

Context

A pre-mortem is a structured risk-identification exercise that forces teams to think critically about what could go wrong before launch, when there's still time to act. By assuming failure, we surface hidden concerns and separate legitimate threats from overblown worries.

Instructions

This is the opening of the README. Read the full README on GitHub.
