What It Does

Product Design Skill guides you through a complete product design workflow in Claude Code, transforming initial concepts into polished PRDs. It orchestrates three interconnected phases: Insight (market research, user personas, JTBD definition), Build (ideation, solution convergence, architecture, user flows), and Validate & Output (design review, one-shot PRD generation).

How It Works

The skill uses guided conversations to shepherd you through structured discovery. Its core intelligence includes:

  • ID Tracking: Every decision traces back—from JTBD to features to modules to flows—ensuring complete traceability
  • Coverage Validation: Automatically checks upstream/downstream completeness when you modify ideas, preventing logic gaps
  • Intelligent Research: Triggers web searches for competitive analysis, market context, and UX best practices at each stage

Built-In Methodologies

Seven proven frameworks are embedded: JTBD (Jobs to Be Done), Value Proposition Canvas, How Might We, SCAMPER, Kano Model, RICE scoring, and Nielsen’s 10 Usability Principles.

Use Cases

Ideal for product managers launching new initiatives, designers starting feature work, or teams needing structured product thinking. Particularly powerful for:

  • Quick PRD generation from rough concepts
  • Ensuring design decisions map to user needs
  • Cross-functional alignment on product direction
  • Competitive and UX research integration

Frequently asked questions

How do I install Product Design Skill?
Copy the product-design directory to Claude Code skills folder at ~/.claude/skills/product-design on macOS/Linux, or %USERPROFILE%\.claude\skills\product-design on Windows. Then restart Claude Code. You can also clone directly from the GitHub repository.
What does ID tracking mean?
ID tracking creates a complete traceability chain: from JTBD (Jobs to Be Done) → Features → Modules → User Flows. Every design decision is linked back to the original user need, making it easy to verify that features actually solve the problems you identified.
How do I trigger the skill?
Just describe your product idea naturally in Claude Code. Examples: 'I want to build an X product', 'Help me write a PRD', 'I have a product idea for...', or 'Analyze this market opportunity for a new product'. The skill auto-activates on product-related requests.
What methodologies are included?
Seven proven frameworks: JTBD (Jobs to Be Done), Value Proposition Canvas, How Might We (HMW), SCAMPER innovation checklist, Kano Model for feature prioritization, RICE scoring for roadmap decisions, and Nielsen's 10 Usability Principles for design validation.
Can the skill search for competitive information?
Yes. The skill automatically triggers web searches at key phases to gather competitive analysis, market trends, and UX best practices. You get research-informed design decisions without manual searches.
What does the skill output?
A production-ready PRD with 13 chapters covering vision, user personas, features, user flows, technical architecture, success metrics, and more. The PRD is generated in one shot after you complete the Insight and Build phases.
How does coverage validation prevent mistakes?
Whenever you add, remove, or modify a product idea, the skill automatically checks that all downstream dependencies are still valid. It prevents logical gaps like defining features without corresponding user flows or flows without supporting architecture.
Is this skill suitable for non-technical product managers?
Absolutely. The skill is designed for product thinkers and designers. No coding knowledge required. Guided conversations walk you through each phase, and the skill handles complex methodology application in the background.

Glossary

JTBD (Jobs to Be Done)
A framework focusing on the specific tasks users are trying to accomplish, rather than user demographics. Helps align product features to genuine customer needs.
ID Tracking
A traceability mechanism linking every product design decision back to its originating user need, creating a complete chain: JTBD → Feature → Module → Flow.
Coverage Validation
Automatic verification that design changes don't create logical gaps or incomplete dependencies. Ensures modifications upstream (like JTBD changes) are reflected downstream (in features and flows).
PRD (Product Requirements Document)
A comprehensive document specifying what a product does, how it works, user needs it addresses, features, success metrics, and technical requirements.
RICE Scoring
A prioritization framework that weighs features based on Reach (how many users), Impact (magnitude of benefit), Confidence (certainty of estimates), and Effort (development cost).
