Before You Build acts as a short pre-build risk gate that evaluates product, feature, MVP, agent, automation, or integration ideas before implementation starts. It restsates the idea, identifies dominant risk dimensions like demand, buyer, distribution, workflow, timing, trust, or scope, provides a risk verdict, and recommends the smallest validation step. Reach for it when the user asks whether to build, scope, validate, prioritize, or sanity-check an idea before writing code or choosing technology.
