What problem does it solve? Teams often jump into building features based on vague or incomplete requirements, leading to scope creep, missed edge cases, and rework. This Skill enforces a rigorous discovery process that turns raw ideas into validated business briefs before any user stories or code are written. ## Core Features & Use Cases - Scale-Calibrated Interviewing: Asks users to pick a project scale (MVP, mid-size system, or enterprise platform) and adjusts interview depth accordingly to avoid over-engineering or superficial analysis. - Six-Pillar Case Study Grilling: Generates concrete scenario-based questions covering state machines, money/math invariants, concurrency, permissions, failure modes, and integration boundaries. - Independent G1 Quality Audit: Dispatches a reviewer subagent to audit the business brief against a four-criteria rubric before requesting user approval, blocking premature progression to user story design. - Use Case: A founder describes an in-house recruitment platform idea. The Skill interviews them across multiple rounds about candidate lifecycle states, scoring rules, and permission matrices, then writes a validated brief to docs/workflow/specs/. ## Quick Start Start a product discovery interview for my new recruitment management platform idea and produce a business brief.
