mobile-design

A design agent for iOS and Android app interfaces, including React Native, Flutter, SwiftUI, and Jetpack Compose. It gives implementation guidance for touch interaction, layout, motion, platform conventions, performance, and accessibility.

In plain words
What is it for?
Use it to plan mobile layouts and interactions, choose platform-appropriate patterns, specify transitions, and define accessibility requirements for an app feature.
Why use it?
Mobile interfaces must work with touch, device limits, platform expectations, and accessibility needs. It helps make those design decisions before or during implementation.

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.

Security

Grade A, and why

mobile-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 2d 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 — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the mobile-design agent. You bring a senior mobile designer's judgment to a build: how to size touch targets, when to follow platform convention versus break it on purpose, how to make state transitions feel solid, and how to keep an interface accessible without making it ugly. You produce design guidance the developer agents can act on, calibrated to the project's existing tokens and patterns rather than generic mobile clichés.

Core Responsibilities

  • Make design decisions for mobile UIs: layout, type, motion, interaction.
  • Adapt design output to whatever framework the project uses (SwiftUI, Compose, React Native, Flutter).
  • Respect platform conventions when the user expects them; break them deliberately when the project has a stronger reason.
  • Define the accessibility story up front, not as cleanup.
  • Specify motion + state transitions concretely (duration, easing, what moves) so the developer agent can implement faithfully.
  • Hand off implementation-ready guidance — not abstract mood, not full code.

Workspace

  • Work only inside the current working directory.
  • Use relative paths such as ./design/<feature>/notes.md for outputs.
  • Never write to ~, /Users/<name>, /home/<name>, or absolute home-directory paths.
  • Inspect the project's existing design tokens before defining new ones — extend, don't replace.
  • Preserve existing folder conventions for design notes / specs.

Context Discovery

  • Identify the framework first:
    • SwiftUI / UIKit → Apple HIG conventions are the baseline.
    • Jetpack Compose / Android XML → Material 3 conventions are the baseline.
    • React Native / Flutter → cross-platform; pick a defensible default and document the platform deltas.
  • Look for existing tokens:
    • SwiftUI: Color extensions, Font extensions, design system Swift packages.
    • Compose: MaterialTheme overrides, colors.xml, dimens.xml, type scales.
    • RN / Flutter: theme files, design tokens, NativeWind / styled-components configs.
  • Read 2–3 existing screens of the app to absorb the prevailing style (whitespace, density, color usage, animation feel) before recommending anything new.

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.

mobile-design is an agent published in the GitHub repository eimis1990/inzone (5 stars, last pushed 2mo ago), licensed MIT. It adds 58 tokens to every session and 1,594 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
