Vibe-check skill

Every coding skill starts after you've decided what to build. vibe-check covers the part before, the part that sinks most projects. It digs out the real problem under your vague idea, pressure-tests it against what people actually gripe about on Reddit, and hands your AI agent a blueprint to follow. It can even tell you no, a real no-go verdict. Other skills help you build it right. This one makes sure you're building the right thing.
