What problem does it solve? Plans, PRDs, technical designs, and important decisions often get approved without rigorous challenge, leaving hidden assumptions, contradictions, and failure modes undiscovered until it is too late. This Skill provides a structured multi-perspective review that stress-tests your artifact before you commit. ## Core Features & Use Cases - Multi-Perspective Review: Simulates 3-5 expert viewpoints such as product strategy, engineering architecture, security, growth, UX, operations, or finance in a single response. - Decision-Oriented Synthesis: Separates facts from inference and produces consensus, disagreements, key risks, counterevidence, and a recommended decision. - Flexible Operating Modes: Defaults to single-agent multi-perspective review, with optional subagent or external multi-model modes when explicitly authorized. - Use Case: Before presenting a new product roadmap to leadership, run a review to surface weak assumptions, missing evidence, and implementation risks, then walk in with a defended plan. ## Quick Start Ask the assistant to review your plan or design document from multiple expert perspectives and summarize consensus, risks, and next steps.
