SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

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.

Frequently Asked Questions about z-market-validate

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I validate a product idea before building it?▼

Run a structured market validation that scans at least four channels such as Reddit, X/Twitter, Hacker News, and Product Hunt for pain and objection signals. This Skill collects 12-30 weighted signal cards, scores six dimensions, and returns a build, explore, park, or avoid recommendation.

What channels does market validation research cover?▼

The default stack covers X/Twitter, Reddit, Hacker News, Product Hunt, Indie Hackers, and app store or review sites. For China-focused ideas it also scans platforms like V2EX, Zhihu, Xiaohongshu, and Weibo when reachable, marking unreachable channels as blocked.

When should I use customer interviews instead of market validation?▼

Use public market validation when the idea is still raw and you need secondary demand signals. Once you are ready to talk to real users with Mom Test style interviews, switch to a customer discovery skill, and use a landing page smoke test when measuring actual signup demand.

How is the market validation composite score calculated?▼

Six dimensions are scored 1-5: demand, willingness to pay, competition intensity, indie fit, time-to-signal, and short-term return. Competition intensity is inverted as 6 minus the raw score, then all six values are averaged and rounded once to two decimals.

What happens if web search tools are unavailable?▼

Unavailable channels are marked as blocked rather than silently skipped. If tools fail entirely, the Skill provides a manual 30-60 minute research checklist covering Reddit, X search, HN Algolia, and Product Hunt instead of fabricating a report.
