Use this skill when users need to validate a launch plan, assess MVP scope, or determine if they're ready to execute. Activates for "validate my plan," "am I ready to launch," "is my scope too big," or when assessing action readiness.
Orchestrate bootstrapping a working MVP from a design or spec document — ingest the doc, plan thin vertical slices, scaffold the first end-to-end slice, then TDD-implement, review, and gated commit. Use to turn an SDD/PRD into a running starting point.
Lean Startup methodology based on Eric Ries' "The Lean Startup". Use when you need to: (1) design MVP scope for new product ideas, (2) define validated learning experiments, (3) create innovation accounting frameworks, (4) decide when to pivot vs. persevere, (5) set up metrics that matter vs. vanity metrics, (6) reduce product development waste, (7) apply scientific method to entrepreneurship, (8) test business model assumptions quickly.
Use inside a product repository when the user wants the full MVP built from their BuilderOS spec documents. Triggers on phrases like "build my MVP", "build the app", "execute the roadmap", "start the build", "work through the whole roadmap", "build everything", or any request to implement the entire plan rather than a single task or phase. Requires `docs/prd.md` and `docs/product-roadmap.md` (plus `docs/product-vision.md` and `docs/design.md` for context). Works through every roadmap task in order — implementing, testing, and verifying each before moving on, marking checkboxes and updating the status line — and runs until all tasks are complete and the magic moment works end to end, then initializes git with an initial commit and offers to connect a remote repo.
End-to-end workflow for taking a new tool idea from research to working MVP. Use when the user has an idea for a CLI tool, library, or small project and wants to go from concept to initial implementation. Triggers on "I have an idea for a tool", "build a new CLI", "create a new project", "kickoff new tool", "I want to build", "let's build a new", "新しいツールを作りたい", "CLIを作る".
Design a conversion loop for a one-person company from reach to lead capture to purchase. Use when Codex needs to explain conversion concepts when needed, verify MVP prerequisites, ask one question at a time, present multiple conversion-path options, and write user-confirmed outputs into `opc-doc/`.
Extract design systems from reference UI images and generate implementation-ready UI design prompts. Use when users provide UI screenshots/mockups and want to create consistent designs, generate design systems, or build MVP UIs matching reference aesthetics.
Use this skill when users need to scope an MVP, define minimum viable features, plan early product development, or determine what to build first. Activates for "what should my MVP include," "scope my MVP," "what to build first," or product scoping questions.
Senior Product Manager responsible for the end-to-end product development process from requirements analysis to product design. Use this when you need support with: (1) Requirements analysis and product direction, (2) User personas and scenario analysis, (3) Feature and interaction design, (4) PRD writing, (5) Feasibility assessment. Trigger words: product design, requirements analysis, user persona, PRD, feature planning, MVP, user story, product solution.
Create a Product Requirements Document (PRD) for your MVP. Use when the user wants to define product requirements, create a PRD, or says "help me write requirements", "create PRD", or "define my product".
Define the smallest viable experiment and MVP for a selected one-person company opportunity. Use when Codex needs to explain what MVP means when needed, verify prerequisites, ask one question at a time, present multiple MVP options, and write user-confirmed outputs into `opc-doc/`.
Guides Claude from idea to working prototype using frameworks from OpenAI, Figma, and Airbnb. Use when starting new product features, planning MVP scope, making build-vs-buy decisions, or guiding users from concept to shippable prototype. Applies AI-first thinking (Kevin Weil), simplicity forcing functions (Dylan Field), and complete experience design (Brian Chesky).
