Helps you write product requirements documents and feature specs with a consistent structure. Guides you through problem statements grounded in evidence, measurable goals that distinguish outcomes from outputs, user stories, success metrics, and technical considerations. The template is opinionated but solid, pushing you to answer the "how will we know this succeeded" question upfront rather than burying it at the end. Good for product managers who want their specs to actually get read and engineers who are tired of vague requirements. The structure works whether you're shipping a small feature or a major product initiative.
