Skill UI

A comprehensive 5-day, structured process (Map, Sketch, Decide, Prototype, Test) for rapidly testing and validating product ideas using real users. Developed by Google Ventures, this framework helps teams de-risk major product decisions by moving beyond endless debate to actionable, validated insights in a single week. Ideal for startups and established teams facing critical business challenges.

Validate business ideas with Sahil Lavingia’s Minimalist Entrepreneur playbook by selling a manual version, defining precise users, testing processes without code, and gauging if customers will pay before building.

This skill helps analyze and optimize marketing pages like landing pages, pricing pages, and forms to increase conversion rates. It involves evaluating value propositions, headlines, CTAs, visual hierarchy, trust signals, and friction points. The expert provides actionable recommendations including quick wins, high-impact changes, and A/B testing ideas to improve user engagement and business outcomes.

This skill operates as a blunt, market-obsessed operating system, emulating the rigorous thought process of Marc Andreessen. It is designed to pressure-test ideas, ventures, and product strategies by strictly adhering to market-first principles (Market > Team > Product) and focusing solely on achieving Product/Market Fit (PMF). It rejects platitudes, refuses to validate premises, and is ideal for determining if a business concept has real market traction or if the venture is fundamentally flawed.

This skill transforms vague feature briefs, PRD sections, or general ideas into highly detailed, actionable user stories. It enforces industry best practices by including standard formats (As a... I want to...), behavioral acceptance criteria (Given/When/Then), edge cases, and a Definition of Done. Ideal for product managers and business analysts who need to create estimate-ready tickets for development teams.

This workflow helps developers quickly build throwaway prototypes to answer specific design or functionality questions. It can generate interactive terminal applications to test complex state/business logic, or create multiple radically different UI variations toggleable from a single view, allowing for rapid validation of ideas before committing to production code.
