Help users de-risk new product bets by testing core assumptions, building low-fidelity prototypes, and gathering high-signal evidence before investing heavy engineering resources.
Use when a founder has a rough product idea and wants autonomous deep validation, market and competitor research, and an evidence-based MVP decision with minimal back-and-forth.
Use when validating a startup idea before building. Produces evidence-based GO/NO-GO decisions using a 9-dimension scorecard (problem, market, timing, moat, unit economics, founder-market fit, feasibility, GTM, risk), a validation ladder (interviews -> smoke test -> concierge/WoZ -> paid pilot), and riskiest-assumption-first experiments.
Critical-thinking brainstorming partner that acts as a requirements analyst. Use when users present ideas, feature requests, or problems they want to solve. Triggers include "I want to build", "help me validate", "users need", "I'm thinking of creating", or any request involving problem/solution validation. This skill aggressively challenges assumptions, questions perceived problems, demands evidence, and ensures solutions address genuine needs before exploring implementation.
Systematically validate business ideas with proven scoring frameworks. Produces comprehensive 2,000-3,000 word validation report with actionable recommendations and go/no-go decision.
Generate, refine, research, and validate startup ideas through an interactive founder-specific idea machine. Use when Codex needs to ask a few focused questions, search current public web signals, rapidly brainstorm startup or SaaS ideas, learn from love/maybe/no reactions, produce additional idea rounds, compare finalists, investigate competitors and existing workarounds, select a promising opportunity, or create an evidence-linked Markdown startup-idea report.
Validate a business idea using the minimalist entrepreneur framework. Use when someone has a business idea and wants to test if it's worth pursuing before building anything.
Deep research and market validation for app ideas. Use when starting a new project, validating an idea, or when the user says "research my idea", "validate my app", or "help me start a new project".
Complete startup launch guidance from idea validation to market entry. Use when planning a new business, validating product ideas, or preparing for launch.
Generate and validate startup ideas through market research, skill-market fit, and iterative refinement.
Use when asked to brainstorm, evaluate whether an idea is worth building, run office hours, or think through a new product idea or design direction before any code is written.
Generate comprehensive Product Requirements Documents (PRD) from idea validation files. Use when users ask to "create a PRD", "generate product requirements", "write a PRD", or want to turn validated ideas into actionable product specs. Works with idea.md and validate.md files from the idea-validator skill.
