What is frontend-designer?

A guide to designing user interfaces, including their components, interactions, accessibility, and speed. Accessibility means making software usable with different abilities and input methods.

Use it to plan component structures, improve forms and navigation, add keyboard and screen-reader support, and optimize frontend performance.

It helps teams make interfaces easier to understand, operate, and maintain.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00052	$0.01081
Opus 5.5	$0.00021	$0.00432
Sonnet 5.5	$0.00010	$0.00216
Haiku 4.5	$0.00005	$0.00108

Security

Grade A, and why

frontend-designer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Frontend Designer Skill

Auto-activated when: User discusses UI/UX, component architecture, accessibility, or frontend design decisions.

Core Capabilities

1. Component Architecture

Component composition patterns
Props vs state decisions
Component reusability strategies
Folder structure (colocation vs separation)
Design system integration

2. UI/UX Patterns

Layout patterns (grid, flexbox, responsive)
Navigation patterns (tabs, drawer, breadcrumbs)
Form design (validation, error handling, multi-step)
Loading states and skeletons
Empty states and error boundaries

3. Accessibility (A11y)

WCAG compliance checklist
Semantic HTML
ARIA labels and roles
Keyboard navigation
Screen reader compatibility
Color contrast (ADHD-friendly palettes)

4. Performance

Code splitting strategies
Lazy loading images/components
Virtual scrolling for long lists
Debouncing/throttling user input
Bundle size optimization

ADHD-Friendly Design Patterns

Visual Hierarchy:

Clear focus states (bold borders, high contrast)
Reduce visual clutter (progressive disclosure)
Consistent spacing (8px grid system)
Limited color palette (3-5 colors max)

Interaction Design:

Immediate feedback (loading spinners, success states)
Undo/redo capabilities
Auto-save (reduce "did I save?" anxiety)
Confirmation dialogs for destructive actions
Keyboard shortcuts for common actions

Cognitive Load Reduction:

One primary action per screen
Hide advanced options behind "Advanced" toggle
Use wizards for multi-step processes
Provide templates/presets
Clear error messages with next steps

Design Philosophy: Solid Indie

Ship Fast Principles:

Start with Tailwind/Bootstrap, customize later
Use proven component libraries (shadcn/ui, Headless UI)
Mobile-first responsive design
Accessibility from day one (easier than retrofitting)

Anti-Patterns to Avoid:

❌ Custom design system before 10K users
❌ Over-abstraction (generic <Button> with 20 props)
❌ Premature animation (ship functionality first)
❌ Pixel-perfect designs (80% is shipping)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
