AF product-design-0to1
Use this skill when the user wants to design a brand-new (0→1) PRD or prototype for a company-internal process management system, where roles and workflows are first-class concerns. Triggers when the user explicitly says "从0到1设计PRD/原型", "设计一个全新的流程系统", or has been routed here by product-design-router. Produces user stories, swimlane diagrams, ER models, state machines, function modules, high-fidelity interactive prototype, RBAC matrix, tracking plan, and detailed PRD through 7 confirmed steps.

How to improve
- The text references files that are not there: add them or drop the references.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
