Spec Product Prd

This generates a product requirements document (PRD) from an already-approved solution.md file in a Chinese SDLC workflow. It's strictly gated: you must have a complete solution document first, or it stops cold. The core idea is turning decisions into testable acceptance criteria without introducing new uncertainty. Instead of "open questions" sections, it forces you to write verification checklists with owners and deadlines. The template enforces scenarios that map directly to ACs, priorities that align with milestones, and business rules you can trace back. It won't let you guess file paths or skip context loading. Use it when you need to freeze scope for engineering handoff and make sure QA can actually write test cases from what you deliver.
