What problem does it solve? Independent developers often build full products before knowing whether anyone wants them. This Skill validates real demand first by producing a landing-page smoke test: concise English copy, one call-to-action, a low-cost traffic plan, and explicit numeric success and kill criteria. ## Core Features & Use Cases - Smoke Protocol Design: Defines hypothesis, primary and secondary metrics, sample plan, success bar, kill criteria, and a 7-14 day timebox before any copy is written. - Landing Copy & Implementation Pack: Produces full English page copy, meta/OG text, headline variants, and a lowest-cost stack (single HTML file, Carrd, static host, or Stripe Payment Link) with form, analytics, and UTM specs. - Traffic Plan & Decision Rules: Delivers a channel-by-channel distribution playbook (X, Reddit, Product Hunt, small ads, warm DMs) plus a decision matrix for strong, mixed, or weak results. - Use Case: A solo founder with a SaaS idea uses this Skill to ship a one-page waitlist site, drive 200 qualified visitors from Reddit and X over ten days, and decide from measured conversion whether to build, rewrite the offer, or park the idea. ## Quick Start Ask the agent to run a landing-page smoke test for your product idea, providing your target customer, the problem you solve, and whether you want a waitlist or pre-order CTA.
