mobile-accessibility

mobile-accessibility is a skill for Claude Code, Codex from makifbaysal/tasktrooper. It costs 46 tokens per session (1,272 once invoked), scanned A, original, Apache-2.0.

A guide to making interactive mobile screens usable with VoiceOver and TalkBack, the built-in iOS and Android screen readers. It covers labels, reading order, headings, text scaling, contrast, motion, and automated checks.

In plain words
What is it for?
Use it when building or changing mobile controls, forms, navigation, images, focus order, screen-reader announcements, or support for larger text and reduced motion.
Why use it?
A screen can look correct while being difficult or impossible to use with a screen reader or larger text. Adding accessibility as part of the build avoids costly later fixes.

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-accessibility 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 8d 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.

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mobile Accessibility

Overview

VoiceOver and TalkBack are not an edge case — they're how a meaningful share of your users, and every store review, go through the screen. Every control that is interactive needs a label a screen reader can speak; every screen needs a sane reading and focus order; text needs to scale.

Core principle: build it accessible the first time — retrofitting labels after the fact means re-testing the whole screen.

Per-stack API table

Concern Flutter Compose SwiftUI
Label Semantics(label:) / tooltip / semanticLabel on Image/Icon contentDescription (null = decorative) accessibilityLabel / Button("…", systemImage:)
Grouping MergeSemantics Modifier.semantics(mergeDescendants = true) .accessibilityElement(children: .combine)
Heading Semantics(header: true) semantics { heading() } .accessibilityAddTraits(.isHeader)
Hidden/decorative ExcludeSemantics Modifier.clearAndSetSemantics {} Image(decorative:)
Custom action CustomSemanticsAction Modifier.semantics { customActions = … } .accessibilityAction(named:)
Live region Semantics(liveRegion: true) Modifier.semantics { liveRegion = … } .accessibilityAddTraits(.updatesFrequently)

Rules that apply everywhere:

  • Every interactive control (button, icon button, tappable row) has a non-empty, human-readable label — never a bare icon with no text or label.
  • Don't rely on a swipe-only gesture for something achievable another way; add a custom action or a visible control alongside it.
  • Group a composite control (e.g. an icon + label that act as one tap target) with the merge/combine API so a screen reader announces it once, not as separate stops.
  • Headings get the heading trait so screen-reader users can jump by section.
  • @ScaledMetric (SwiftUI) / theme text styles (Flutter, Compose) everywhere text appears — never a hardcoded point/sp size that ignores the system font-scale setting.
  • Respect reduce-motion: MediaQuery.disableAnimationsOf(context) (Flutter), LocalAccessibilityManager/animation duration checks (Compose), @Environment(\.accessibilityReduceMotion) (SwiftUI) — skip or shorten a decorative animation, never a functional state change.
  • Contrast: body text ≥4.5:1, large text ≥3:1 against its background in both light and dark — check this when picking theme token values, not per-screen.

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.
