common-mobile-ux-core

common-mobile-ux-core is a skill for Claude Code, Codex from HoangNguyen0403/agent-skills-standard. It costs 45 tokens per session (483 once invoked), scanned A, original, MIT.

Guidelines for designing touch-first mobile screens, including button sizes, screen cutouts, keyboards, text, and pressed states. Safe areas are the parts of a screen that avoid notches and system controls.

In plain words
What is it for?
Use it when building or reviewing mobile screens, touch interactions, forms, keyboard behavior, and support for iOS or Android screen insets.
Why use it?
They help prevent controls that are hard to tap, content hidden by device edges, and desktop interactions that do not work on phones.

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

common-mobile-ux-core 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 9d 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

Mobile UX Core

Priority: P0 (CRITICAL)

Guidelines

  • Touch Targets: Min 44x44pt (iOS) / 48x48dp (Android). Add padding if needed.
  • Safe Areas: Wrap content in SafeArea/WindowInsets. Avoid notches.
  • Interactions: Use active states (no hover). Haptic feedback (short).
  • Typography: Min 16sp body. Line height 1.5x.
  • Keyboards: Auto-scroll inputs. Set InputType (email/number) & Action.

Code Examples

  • Correct: IconButton(icon: Icon(Icons.close), padding: EdgeInsets.all(12))
  • Avoid: Icon(Icons.close, size: 16) (Touch target too small)

Review Workflow

  1. Test the smallest interactive element against 44pt iOS / 48dp Android.
  2. Test content, keyboard, and fixed actions with notch/home-indicator/window insets.
  3. Check pressed, loading, error, and disabled states; do not port desktop hover behavior.
  4. Verify platform conventions separately before calling the screen complete.

Anti-Patterns

  • No Hover Effects: Mobile no cursor; use pressed/active states instead
  • No Tiny Targets: All clickable elements must ≥44pt
  • No Fixed Bottoms: Always account for Home Indicator and Keyboard safe areas
  • No OS Mixing: Respect Material (Android) and Cupertino (iOS) conventions separately

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
