SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve? AI-generated frontend interfaces often look generic, inconsistent, or off-brand because they lack project context and design discipline. This Skill grounds every design task in your project's PRODUCT.md and DESIGN.md context files, then applies shared design laws and specialized commands to produce distinctive, production-grade UI work. ## Core Features & Use Cases - Context-gated design workflow: Loads PRODUCT.md and DESIGN.md before any edits, classifies work into brand or product registers, and enforces preflight gates so output matches your brand instead of generic templates. - 23 sub-commands across the design lifecycle: Build (craft, shape, teach, document, extract), Evaluate (critique, audit), Refine (polish, bolder, quieter, distill, harden, onboard), Enhance (animate, colorize, typeset, layout, delight, overdrive), Fix (clarify, adapt, optimize), and Iterate (live browser-based variant mode). - Anti-AI-slop guardrails: Absolute bans on gradient text, side-stripe borders, glassmorphism defaults, and hero-metric templates, plus a two-altitude category-reflex check to avoid training-data aesthetics. - Use Case: Run $impeccable critique dashboard to get a scored UX review of your dashboard, then $impeccable bolder to amplify a bland landing page, then $impeccable audit to verify accessibility, performance, and responsive quality before shipping. ## Quick Start Ask the agent to run $impeccable teach to set up your project's design context, then invoke $impeccable craft followed by a feature description to design and build it.

Frequently Asked Questions about impeccable

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

FAQPage Schema
How do I improve a bland or generic frontend design?▼

Run the bolder command with a target, such as $impeccable bolder landing-page. It amplifies typography scale, color commitment, spatial drama, and motion while avoiding AI-slop patterns like purple-blue gradients and glassmorphism.

How do I audit a UI for accessibility and performance issues?▼

Run $impeccable audit with a target area. It scores five dimensions (accessibility, performance, theming, responsive design, anti-patterns) from 0-4 each, tags findings with P0-P3 severity, and recommends follow-up commands to fix them.

What are PRODUCT.md and DESIGN.md and why are they required?▼

PRODUCT.md captures users, brand, tone, and strategic principles; DESIGN.md captures colors, typography, and components. The skill loads both before any design work so output stays on-brand. Run $impeccable teach to create them.

Can I iterate on UI designs visually in the browser?▼

Yes. The live command starts an interactive variant mode where you select elements in the browser, pick a design action, and receive AI-generated HTML and CSS variants hot-swapped via HMR. It requires a running dev server.

When should I not use this frontend design skill?▼

Do not use it for backend-only or non-UI tasks. It is scoped to frontend interfaces: websites, dashboards, components, forms, and visual states. Server logic, APIs, and data pipelines are outside its scope.

What design patterns does the skill ban outright?▼

It bans side-stripe borders over 1px, gradient text via background-clip, decorative glassmorphism, hero-metric templates, identical card grids, modals as a first choice, pure #000 or #fff, bounce easing, and em dashes in copy.
