Before You Build

Run a compact pre-mortem before implementation. The goal is not to block building; it is to identify the highest-risk assumption, the smallest validation step, and the build scope that should be delayed until evidence improves.

When To Use

Use this skill when a user asks to build or ship:

• A new product, MVP, prototype, landing page, SaaS app, marketplace, content site, agent workflow, or internal tool
• A major feature with unclear adoption, revenue, retention, trust, or distribution impact
• A public launch asset where weak positioning could waste development or promotion effort

Skip this skill when the task is a narrow implementation fix, refactor, test repair, dependency update, or already-validated change with clear acceptance criteria.
