SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you quickly visualize a design direction before committing engineering time, reducing ambiguity and preventing costly implementation churn.

Core Features & Use Cases

  • Throwaway HTML mockups: Creates short-lived browser-ready sketches to compare multiple interface directions.
  • Variant exploration: Produces 2–3 alternatives so you can evaluate layout, hierarchy, and interaction choices side by side.
  • Workflow integration: Saves sketch outputs into .planning/sketches/ and aligns them with Ferrox planning, state tracking, and handoff patterns.
  • Use case: When a product idea is still fuzzy, use this Skill to explore the UI shape, identify missing requirements, and package the best direction for build follow-up.

Quick Start

Create three mockup variants for a dashboard onboarding flow and save them in the project’s sketch planning folder.

FAQPage Schema
How do I create HTML mockups to explore UI design directions before implementation?

You create throwaway HTML mockups to quickly visualize interface directions, reducing ambiguity and preventing implementation churn before committing engineering time. The Skill generates short-lived browser-ready sketches to compare layout and interaction choices side by side.

Can I generate multiple design variants for a single interface using HTML mockups?

Yes, HTML mockups can produce 2–3 alternative variants so you can evaluate layout, hierarchy, and interaction choices side by side. This variant exploration helps identify the best interface direction before starting the build process.

What is the best way to plan product interfaces when the design idea is still fuzzy?

Creating throwaway HTML sketches is the best way to explore the UI shape when an idea is fuzzy. This process helps identify missing requirements and packages the best direction for build follow-up and handoff.

Do I need a specific project directory structure to save HTML sketches?

HTML sketches are saved into the project's `.planning/sketches/` directory. This aligns the mockup outputs with Ferrox planning, state tracking, and handoff patterns for organized project sketch directory management.

How does variant exploration work for comparing interface layouts?

Variant exploration works by generating multiple HTML mockup alternatives so you can compare layout, hierarchy, and interaction choices side by side. This allows you to evaluate different design directions before committing to a final implementation.

Are HTML mockup sketches meant to be permanent files in the project?

No, HTML mockups are throwaway sketches created for short-lived exploration. They serve to visualize design directions temporarily before implementation, and are stored in the planning folder for reference during handoff.
