SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Helps you explore UI/design directions quickly by turning rough ideas into throwaway HTML mockups, so you can compare variants before committing to implementation.

Core Features & Use Cases

  • Idea mode sketching: Generate 2–3 throwaway HTML mockup variants from a design idea to pressure-test layout, flow, and interaction assumptions.
  • Frontier mode consistency: Analyze the existing sketch landscape and propose next “frontier” sketches to reduce duplication and improve directional coherence.
  • Planning + commit integration: Saves sketches into .planning/sketches/ and aligns results with GSD commit/state tracking and handoff workflows.

Quick Start

Run gsd-sketch to produce 2–3 HTML mockup variants for a design idea and store them under .planning/sketches/.

Frequently Asked Questions about gsd-sketch

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create HTML mockups to test UI design variants before implementation?▼

You create throwaway HTML mockups by providing a design idea, which generates 2-3 variants to pressure-test layout and interaction assumptions. This allows you to compare design directions quickly before committing to implementation.

How do I generate interaction design sketches that fit into my existing planning workflows?▼

Interaction design sketches integrate with planning workflows by saving generated HTML mockups directly into the .planning/sketches/ directory. This aligns results with GSD commit tracking and state handoffs.

Can I analyze existing UI sketches to propose next steps and reduce duplication?▼

Yes, frontier mode analyzes the existing sketch landscape to propose next directional sketches. This reduces duplication and improves directional coherence across your interaction design exploration.

What is the best way to explore early product design directions without committing to code?▼

The best way to explore early product design directions is generating throwaway HTML mockups. This validates interaction patterns and compares variants prior to implementation without writing production code.

Do I need any specific dependencies to run UI sketching for product prototyping?▼

No specific dependencies are required to run UI sketching for product prototyping. The Skill operates independently to generate HTML mockups and manage them within your planning directory structure.
