What problem does it solve? Teams often build features without validated demand, prioritize roadmaps by gut feel, and ship tickets that say "Build X" without explaining why it matters to users. This Skill enforces validation before implementation so engineering effort goes toward evidenced customer needs. ## Core Features & Use Cases - Working Backwards PRDs: Drafts Press Release format PRDs with premises, 10x vision, narrowest wedge scope, and success metrics so engineering can estimate without clarifying questions. - RICE Prioritization: Scores backlogs with (Reach x Impact x Confidence) / Effort, presenting assumptions so users can challenge inputs rather than outputs. - PMF Diagnostics: Applies the Sean Ellis 40% test and pivot frameworks (zoom in, zoom out, customer, need, channel) to determine whether to iterate, pivot, or scale. - Use Case: A founder says "add dark mode." The Skill maps the request to an Opportunity in the Opportunity Solution Tree, asks for demand evidence, and requires a RICE score before any PRD is written. ## Quick Start Ask the product manager skill to evaluate a feature idea and produce a Working Backwards PRD with a RICE-scored priority ranking.
