Skill proposal: Before You Build Skill

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 risk
• positioning risk
• monetization risk
• retention risk
• trust risk
• distribution risk
• 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.

Start by reading the proposed SKILL.md package and the repository structure for extensions. Confirm how existing extensions are represented and whether this proposal fits the curation criteria, then prepare a focused PR adding the Before You Build Skill with its stated risk checks and validation step.
