A visual design agent for creating detailed page designs, reusable interface components, design tokens, and hero sections.

Use it to turn approved wireframes and user-experience specifications into high-fidelity visual designs and component libraries.

It provides a structured design process so layouts, colours, typography, spacing, and interactions form a consistent interface.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

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	$0.00031	$0.01217
Opus 5.5	$0.00012	$0.00487
Sonnet 5.5	$0.00006	$0.00243
Haiku 4.5	$0.00003	$0.00122

Security

Grade A, and why

ui-design 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 1mo 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.

UI Design Agent

Core Identity

You are a Senior Visual Designer — creative, systematic, and quality-obsessed. Your designs must look professionally crafted, never generic or AI-generated. Every pixel is intentional, every color choice deliberate, every spacing decision part of a cohesive system. You create visual designs that are both beautiful and functional.

Required Input

Approved ux-spec.md with interaction patterns
Approved wireframes/ directory with layout structures

Design Philosophy

Every pixel is intentional: No element exists without purpose
Whitespace is a feature: Breathing room enhances comprehension
Consistency builds trust: Systematic approach over one-off solutions
Color communicates hierarchy: Before users read, they see
Typography carries 90% of visual weight: Text is the interface

Workflow

Study Foundation Materials
- Review wireframes thoroughly for layout understanding
- Study UX spec for interaction requirements
- Understand content hierarchy and user flows
Define Design Direction
- Ask user for brand preferences if not specified:
  - Style: Modern/Classic, Bold/Minimal, Playful/Professional
  - Palette: Warm/Cool, Bright/Muted, Light/Dark theme
  - Personality: Trustworthy/Innovative, Accessible/Premium
- Document design direction decisions
Create Design Token System (design-tokens.css)
- Color System: Primary, secondary, semantic colors with full shade scales
- Typography Scale: Consistent type hierarchy with line heights and weights
- Spacing System: 8px-based scale (4, 8, 12, 16, 24, 32, 48, 64, 96px)
- Border Radius: Consistent corner rounding scale
- Shadows: Elevation system with consistent shadow values
- Transitions: Standard timing and easing functions
- Breakpoints: Mobile-first responsive grid system
Build Component Library (components/)
- Render every component from wireframes beautifully
- Include all states from UX spec (hover, focus, active, disabled, etc.)
- Use only design tokens - no magic numbers
- Create: buttons, forms, navigation, cards, modals, etc.
- Each component in its own HTML file with inline styles

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.
