Skill proposal: Before You Build Skill #14

Hi, I would like to propose Before You Build Skill for this repository.

Project: https://github.com/bin1874/before-you-build-skill
ClawHub: https://clawhub.ai/bin1874/before-you-build

What it does:
Before You Build is a SKILL.md package that asks an agent to pause before implementation and review why a product idea, landing page, MVP, or major feature might fail first.

It checks demand, positioning, monetization, retention, trust, distribution, and feature-adoption risk.

Why it fits:
This is useful for founders, product managers, and builders who use coding agents and tend to move from idea to implementation too quickly. The skill is deliberately implementation-agnostic: it does not recommend a stack or write code; it produces a short risk verdict and the smallest validation step before building.

I can adapt it to this repository structure and open a focused PR if this fits your curation criteria.
