Repository-based product discovery for Cursor and Codex, preserving evidence and decisions across hypotheses, prototypes, PRDs, and implementation.
Skill Claude CodeCodex
Defines structural design artifact formats — information architecture, user flows, content model, brand direction, Visual Tokens, and AI interaction model. Use when creating or reviewing design artifacts that precede prototype generation.
Skill Claude CodeCodex
Provides Business Model Canvas, Value Proposition Canvas, and TAM/SAM/SOM market analysis frameworks. Use when assessing Viability risk, sizing markets, mapping value propositions, conducting competitive analysis, or identifying market gaps.
Skill Claude CodeCodex
Integrates design principles, WCAG 2.2 AA accessibility, persona context, and state design into product decisions. Use when reviewing UX decisions, checking accessibility, applying design principles, or ensuring state coverage in acceptance criteria.
Skill Claude CodeCodex
Manages hypothesis lifecycle, enforces validation criteria, time budgets, and confidence scoring rules. Use when creating hypotheses, updating confidence scores, setting validation criteria, handling timeouts, or recording validation results.
Skill Claude CodeCodex
Defines PRD structure, user story format with 4 Risks assessment, EARS-format acceptance criteria, and delivery readiness thresholds. Use when writing PRDs, drafting user stories, defining acceptance criteria, or reviewing PRD quality and completeness.
Skill Claude CodeCodex
Defines 4 Risks confidence thresholds, OST hierarchy levels, Knowledge Pyramid tiers, and state design requirements. Use when evaluating user stories, setting confidence scores, referencing OST levels, scoping MVP, or determining validation sufficiency.
Skill Claude CodeCodex
Defines evidence-grounded prototype quality and external-generator prompt construction. Use when generating or evaluating a prototype, or exporting a prompt for Lovable, v0, or a similar tool.
Skill Claude CodeCodex
Selects and defines the structural design context needed by a prototype or PRD. Use when shared information architecture, flows, content, brand, Visual Tokens, or AI interaction decisions are missing.
Skill Claude CodeCodex
Creates a delivery-ready PRD from validated hypotheses with material 4 Risks evidence and necessary traceability. Use when turning validation results into requirements or user stories.
Skill Claude CodeCodex
Frames product Opportunities and creates decision-relevant hypotheses from available evidence. Use when exploring a problem, market opportunity, or user need.
Skill Claude CodeCodex
Creates or updates evidence-backed personas with the context and JTBD needed for product decisions. Use when user segments or behavior affect discovery, design, or requirements.
Skill Claude CodeCodex
Exports an evidence-grounded prompt for Lovable, v0, or a similar external prototype generator. Use when the desired artifact is a reusable generator prompt rather than an internally generated HTML prototype.
Skill Claude CodeCodex
Use when a design-capable human wants to refine the auto-derived Visual Tokens in docs/product/design/brand-direction.md.
Skill Claude CodeCodex
Orchestrates reflection by updating affected artifacts and distilling reusable knowledge from validation results.
Skill Claude CodeCodex
Validates a hypothesis with a risk-appropriate method and records decision-relevant evidence. Use when testing Value, Usability, Feasibility, or Viability assumptions.
Skill Claude CodeCodex
Defines or updates product vision, outcomes, NSM, and decision-relevant design principles. Use when starting a product, changing strategy, or reassessing outcomes.
