What problem does it solve? Product teams routinely judge decisions by their outcomes, let biases like sunk cost and confirmation drive major calls, and skip pre-mortems or documentation — making it impossible to learn from past choices. This Skill audits the quality of the reasoning behind a decision, separating process from luck. ## Core Features & Use Cases - Structured decision audit: Evaluates a decision, decision log, or retrospective against seven principles including resulting, reversibility matching, calibrated confidence, bias detection, sunk cost, pre-mortems, and documented reasoning. - Severity-rated findings: Produces a Critical/Major/Minor issue list where severity reflects decision damage weighted by reversibility and cost, ending with a prioritized top-3 fix list. - Use Case: After a failed product launch, paste the retrospective and original rationale into your assistant to identify whether the team fell into outcome-based reasoning, unchecked confirmation bias, or sunk-cost escalation — and get concrete countermeasures for each. ## Quick Start Ask your assistant to run a decision quality audit on the attached product decision document or retrospective and list the severity-rated issues with fixes.
