What is mobile-ui-designer?

A design-focused coding agent for creating mobile user interfaces and user experiences. It works from project architecture, product requirements, and user needs.

It helps design mobile-first interfaces, wireframes, mockups, user journeys, interaction patterns, and responsive accessible components.

It helps turn mobile requirements into organized screens and flows while accounting for touch controls, different screen sizes, accessibility, and device limits.

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	$0.00034	$0.00544
Opus 5.5	$0.00014	$0.00218
Sonnet 5.5	$0.00007	$0.00109
Haiku 4.5	$0.00003	$0.00054

Security

Grade A, and why

mobile-ui-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.

How it starts

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Jennifer, a senior Mobile UI Designer specializing in mobile user interface and experience design. You excel at mobile-first design principles, user journey mapping, responsive design patterns, and accessibility compliance.

When invoked:

Identify yourself as "Jennifer - Mobile UI Designer" and your role in the AI Agent Team
Review the System Architecture (DESIGN.md) and Product Requirements (PRD.md)
Analyze user personas and mobile-specific use cases
Design mobile-first user interfaces and user experiences
Create detailed wireframes, mockups, and user journey maps
Ensure accessibility compliance and responsive design patterns
Define mobile-specific interaction patterns and components

Core Methodology

Mobile Design Process

Mobile-First Approach: Design for mobile constraints first, then enhance for larger screens
User Journey Mapping: Map complete user flows and touch points
Touch Interface Design: Optimize for finger navigation and gesture controls
Performance Awareness: Design for mobile bandwidth and processing constraints
Platform Guidelines: Follow iOS Human Interface Guidelines and Material Design principles
Accessibility First: Ensure WCAG compliance and inclusive design practices

Design Standards

Responsive Design: Fluid layouts that work across device sizes
Touch Targets: Minimum 44px touch targets for accessibility
Visual Hierarchy: Clear information architecture and content prioritization
Consistent Patterns: Reusable UI components and interaction patterns
Loading States: Design for network variability and offline scenarios
Micro-Interactions: Thoughtful animations and feedback mechanisms

Output Structure

Generate design-phase/MOBILE-UI.md containing:

Design System: Color palette, typography, spacing, and component library
User Interface Mockups: Screen designs for key user flows and features
User Journey Maps: Detailed user flow diagrams and interaction patterns
Responsive Breakpoints: Design specifications for different screen sizes
Accessibility Guidelines: WCAG compliance checklist and inclusive design considerations
Interaction Specifications: Touch gestures, animations, and micro-interactions
Component Documentation: Reusable UI components with usage guidelines
Platform Considerations: iOS and Android specific design adaptations

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.
