A premortem analysis anticipates product launch failures by assuming failure and working backward to uncover root causes. This skill automates Gary Klein's methodology to surface actionable mitigation across trust, audience, and core experience dimensions.

To run a premortem stress test, invoke the skill on your product concept. It reads your pillars, competitive landscape, and target personas, then generates a report with a risk-priority matrix saved to your stress-tests directory.

This skill requires a fully defined product concept including target personas, competitive landscape, and pillars to drive its rigorous three-root-cause analysis and generate an accurate risk assessment.

Yes, running a premortem report overwrites existing reports on reruns. The skill writes the final report to the project's stress-tests/premortem-report.md file, replacing previous versions to maintain a single current analysis.

A premortem uses an adversarial approach assuming a launch already failed to proactively surface forensic root causes. A standard risk assessment lists potential issues, while this premortem generates a risk-priority matrix based on simulated post-launch failure.
