Devil's advocate analysis to surface risky assumptions across four risk areas.
Identifies risk assumptions in existing product feature ideas across value, usability, viability, and technical feasibility using devil's advocate analysis from PM, designer, and engineer perspectives. Use for validating ideas and assessing risks.
Extracts and risk-rates hidden assumptions from product briefs or PRDs across desirability, feasibility, viability, and usability categories. Produces a prioritized assumption map with confidence/impact scores and validation recommendations.
Use this skill when the user asks to "map assumptions", "identify assumptions", "what are we assuming", "assumption audit", "what could go wrong with this idea", "test our assumptions", "what do we need to validate", "identify our riskiest assumption", or when reviewing an idea or PRD and wants to surface hidden bets before building. Do NOT use this skill for general risk analysis — that is part of the pre-mortem skill.

You are stress-testing a feature idea for $ARGUMENTS.
If the user provides files (designs, PRDs, research), read them first.
The user will describe their product, objective, market segment, and feature idea. Work through these steps:
Think from three perspectives about why this feature might fail:
Identify assumptions across four risk areas:
For each assumption, note:
Think step by step. Be thorough but constructive — the goal is to strengthen the idea, not kill it.
