What problem does it solve? Independent developers can build software quickly but struggle to judge whether an idea has real demand before investing months of work. This Skill turns a raw product idea into an evidence-backed validation report based on public market research rather than guesswork. ## Core Features & Use Cases - Multi-channel demand scan: Searches X/Twitter, Reddit, Hacker News, Product Hunt, Indie Hackers, review sites, and Chinese platforms (when relevant) for demand, objection, and pricing signals, captured as weighted signal cards. - Structured scoring and verdict: Scores demand reality, willingness to pay, competition intensity, indie fit, time-to-signal, and short-term return on a 1-5 scale, then produces a composite score and a recommendation band (build wedge now, explore with spike, park, or avoid). - Fixed report contract: Delivers a templated report with an executive verdict, competition analysis, entry wedges, next 48-hour actions, and a seven-row evidence handoff table for downstream skills. - Use Case: A solo founder with an idea for an invoicing tool for freelancers runs this Skill to scan communities for pain signals, analyze substitutes, and receive a go/narrow/stop recommendation with cited sources. ## Quick Start Ask the agent to validate your product idea with z-market-validate, describing the one-liner, target audience, and geography.
