This handles the full lifecycle of product management work, from writing PRDs to breaking down sprints. You get structured templates for requirements docs, user stories with acceptance criteria, priority frameworks (P0/P1/P2), and risk assessment matrices. It covers the practical stuff like functional specs, data schemas, API definitions, and non-functional requirements. The templates are comprehensive, maybe overly so if you just need a quick feature spec, but genuinely useful if you're shipping something real and need stakeholder alignment. Works well for both waterfall-style PRDs and agile story mapping. The Chinese source material is thorough about edge cases and business rules, which is refreshing.
