design-mobile

design-mobile is a command for coding agents from fusengine/agents. It costs 51 tokens per session (482 once invoked), scanned A, original, MIT.

A command for designing an iOS or Android screen or flow as a device-framed HTML mockup with a developer handoff specification.

In plain words
What is it for?
Use it for mobile onboarding, settings screens, pricing screens, and other flows, choosing iOS or Android as the target.
Why use it?
It lets teams review the mobile experience visually before an iOS or Android developer writes the native 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.

Security

Grade A, and why

design-mobile 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 yesterday.

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.

What it actually says

/design:mobile — iOS/Android Mockup + Handoff (MOBILE scope)

Design a mobile screen or flow. This command never writes SwiftUI or Compose — the deliverable is a device-framed HTML mockup plus a handoff spec for the platform developer.

Complete documentation: skills/design-ios/SKILL.md or skills/design-android/SKILL.md.

Usage

/design:mobile ios onboarding flow
/design:mobile android settings screen
/design:mobile ios pricing paywall

Workflow

  1. Read skills/design-method/SKILL.md — the 4-question brief and signature element still apply; no inspiration browsing for mobile (platform HIG/Material references replace it).
  2. If no design-system.md exists, read skills/design-system/SKILL.md first to establish tokens; otherwise reuse the existing one.
  3. Route by argument:
    • iosskills/design-ios/SKILL.md — Dynamic Type, semantic colors, exact device viewports, Liquid Glass where it fits, 44×44pt touch targets.
    • androidskills/design-android/SKILL.md — Material 3 (Expressive) type scale, shape scale, color roles, window size classes, 48×48dp touch targets.
  4. Build the device-framed HTML mockup at exact viewport/window-size dimensions.
  5. Write the handoff spec (SwiftUI-ready or Compose-ready) — named tokens only, explicit sizing/states/spacing.
  6. Read skills/design-review/SKILL.md, mockup-scoped: contrast check on the mockup, screenshot it, no full site audit loop.

Forbidden

Writing SwiftUI or Jetpack Compose code. Inventing a numeric fact not in design-ios/design-android's references (mark it "to reconfirm" instead). Inspiration-site browsing.

Changes

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.
