Product discovery workflows for Claude Code: test decision-changing assumptions and turn the evidence into independently reviewed PRDs.
Skill Claude CodeCodex
Defines structural design artifact formats — information architecture, user flows, content model, brand direction, and AI interaction model. Use when creating or reviewing structural design documents 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
Generates self-contained HTML prototypes with design context from project files. Read design principles, personas, and hypothesis files, then produce a working prototype for Usability and Value risk validation. Use when creating prototypes or validating through tangible artifacts.
Skill Claude CodeCodex
Define structural design foundation — information architecture, user flows, content model, brand direction, and AI interaction model — from validated opportunities and hypotheses.
Skill Claude CodeCodex
Orchestrate PRD creation from validated hypotheses — standard PRD output with 4 Risks confidence and hypothesis traceability.
Skill Claude CodeCodex
Orchestrate Opportunity discovery and hypothesis generation through business and user perspectives.
Skill Claude CodeCodex
Create or update personas with demographic, contextual, JTBD, and behavioral data.
Skill Claude CodeCodex
Optional side-workflow for design experts to refine Concrete Tokens in brand-direction.md when a named downstream consumer needs reproducible values.
Skill Claude CodeCodex
Orchestrate structured reflection — update target artifacts with learnings, distill knowledge across hypotheses, and maintain INDEX.md.
