What problem does it solve? Validating a product idea against real user needs normally requires recruiting and interviewing actual customers, which is slow and expensive. This Skill lets an agent role-play a detailed customer persona, pressure-test a product pitch across problem, solution, value, and trust axes, and surface real objections before any field research happens. ## Core Features & Use Cases - Persona Role-Play: The agent embodies a persona from a profile, speaks in first person, doubts, negotiates, and reacts like a real human across a five-phase interview protocol. - Three Interview Modes: Devil's Advocate (maximum criticism), Enthusiast (early adopter), and Balanced (default) for different validation goals. - Structured Debrief: Produces an interview report with a per-axis star-rated verdict, a buy/no-buy conclusion, unresolved objections, key quotes, and recommendations. - Pipeline Mode: Can run self-play (agent acts as both persona and interviewer) from brief and personas inputs, writing the report artifact for an orchestrator. - Use Case: Before pitching a fintech assistant to investors, run a Devil's Advocate interview with a founder persona to discover that trust in calculated metrics and subscription pricing are the blocking objections. ## Quick Start Ask the agent to run a persona interview in Devil's Advocate mode using your product brief and primary persona, then save the verdict report.
