The write-a-prd skill is for turning an idea into a structured product requirements document. It combines clarification, codebase context, and feature decomposition so the resulting spec is grounded rather than abstract.
In practice, use it when a feature is still vague and needs to be turned into a document that engineering can actually implement. It is a good bridge between rough product intent and concrete delivery planning.
