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.

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 | $0.00051 | $0.00482 |
| Opus 5.5 | $0.00020 | $0.00193 |
| Sonnet 5.5 | $0.00010 | $0.00096 |
| Haiku 4.5 | $0.00005 | $0.00048 |
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 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.
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
- 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). - If no
design-system.mdexists, readskills/design-system/SKILL.mdfirst to establish tokens; otherwise reuse the existing one. - Route by argument:
ios→skills/design-ios/SKILL.md— Dynamic Type, semantic colors, exact device viewports, Liquid Glass where it fits, 44×44pt touch targets.android→skills/design-android/SKILL.md— Material 3 (Expressive) type scale, shape scale, color roles, window size classes, 48×48dp touch targets.
- Build the device-framed HTML mockup at exact viewport/window-size dimensions.
- Write the handoff spec (SwiftUI-ready or Compose-ready) — named tokens only, explicit sizing/states/spacing.
- 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.
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.

design-mobile is a command published in the GitHub repository fusengine/agents (34 stars, last pushed 25d ago), licensed MIT. It adds 51 tokens to every session and 482 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
