ui-design

star 13

The UI/UX quality gate and build guide for every visual output — landing pages, dashboards, web apps, portfolios, tools, any HTML the user will see. Merges visual-design methodology (palette, typography, layout, anti-AI-slop) with concrete build guidance, including when and how to use open-source component libraries (shadcn/ui, HeroUI, coss ui) to reduce work and raise quality. MUST USE together with project-builder whenever a project produces visual HTML/CSS/JS. project-builder owns the engineering workflow; this skill owns how the result looks and feels.

name: ui-design version: 1.2.0 description: | UI/UX quality gate and build guide for every visual output — landing pages, dashboards, web apps, portfolios, and tools. ui-design remains the main entry point.

Integration model: ui-design main trunk + taste-skill overlay.

  • ui-design owns engineering quality (track selection, component-library strategy, accessibility, responsiveness, theming, performance, preview delivery)
  • taste-skill is invoked inside the ui-design workflow for style decisions (Brief Inference, Design Dials, Anti-slop hard rules)

UI Design Skill

This skill is the single entry point for visual work.

Use it for any user-facing HTML/CSS/JS output: landing pages, dashboards, product UI, internal tools, and portfolio pages.


Step 1 — Pick the build track

Choose deliberately before coding:

  • Track A (hand-built): static preview, vanilla HTML/CSS/JS, quick custom pages
  • Track B (component library): React/Vite/Next project using shadcn/ui, HeroUI, or coss ui

Track decision and component-library strategy are always owned by ui-design.


Step 2 — Taste Overlay Contract (mandatory)

Inside ui-design workflow, invoke taste-skill for exactly these 3 style blocks:

  1. Brief Inference
  2. Design Dials (layout variance / motion intensity / visual density)
  3. Anti-slop hard rules

Boundary

  • ui-design keeps ownership of engineering quality and delivery.
  • taste-skill provides style direction and anti-template taste constraints.

This avoids overlap with ui-design’s engineering references (component libraries, a11y, preview, data dashboard implementation).


Step 3 — Runtime order (use this every time)

  1. Use ui-design to select Track A/B.
  2. Run taste Brief Inference before writing UI code.
  3. Apply taste Design Dials to set style direction.
  4. For any interactive page, define a motion plan first (what animates, why, frequency, duration, easing, reduced-motion path).
  5. Implement with ui-design engineering rules (a11y/theme/responsive/component strategy/performance).
  6. Run taste Anti-slop check as final style gate before delivery.

One sentence summary:

  • taste decides style character
  • ui-design guarantees robust implementation

Hard rule: if the page has interactions, motion design is mandatory (at least tactile feedback + state transition feedback). Static-looking interaction states are treated as incomplete UI.


Step 4 — Conflict arbitration

When rules overlap:

  • Style conflict → taste-skill wins
  • Engineering safety/correctness conflict → ui-design wins

Engineering safety includes: accessibility, responsive stability, interaction reliability, runtime correctness, and performance constraints.


Step 5 — Where to read/download taste-skill (no local mirror)

Do not maintain a local mirror or version-stamp file.

Always read/update taste rules directly from GitHub:

  • Repo: https://github.com/Leonxlnx/taste-skill
  • Main skill to consult: https://github.com/Leonxlnx/taste-skill/blob/main/skills/taste-skill/SKILL.md
  • Raw download URL: https://raw.githubusercontent.com/Leonxlnx/taste-skill/main/skills/taste-skill/SKILL.md
  • Full skill package directory: https://github.com/Leonxlnx/taste-skill/tree/main/skills

When taste-skill updates, re-check the GitHub source directly and apply needed changes in the ui-design overlay contract.
