What problem does it solve? Product managers often struggle to justify build/don't-build decisions with financial rigor, relying on gut feel or generic scoring frameworks. This Skill guides you through a structured financial evaluation of any feature so you can defend prioritization decisions with concrete ROI math. ## Core Features & Use Cases - Revenue Connection Analysis: Classifies features by direct monetization, retention improvement, conversion lift, or expansion enablement, then calculates the corresponding revenue impact. - Cost Structure & ROI Calculation: Computes development cost, ongoing COGS/OpEx, contribution margin, payback period, and year-over-year ROI. - Actionable Recommendations: Delivers one of four recommendation patterns (build now, build for strategic reasons, don't build, build later) with supporting math and next steps. - Use Case: Deciding whether to build a $100K time-tracking add-on? Provide your MRR, ARPU, churn, and adoption estimates, and receive a full payback and ROI breakdown with a build recommendation. ## Quick Start Ask the agent to evaluate whether a specific feature is worth building, providing your current MRR, ARPU, churn rate, gross margin, and development cost estimate.
