mobile-accessibility

mobile-accessibility is a skill for Claude Code from simiancraft/simiancraft-skills. It costs 0 tokens per session (879 once invoked), scanned A, original, MIT.

A guide to the accessibility tree: the structured list of app elements that screen readers such as VoiceOver and automation tools can read.

In plain words
What is it for?
It helps choose stable identifiers for automated tests and meaningful labels for spoken accessibility descriptions.
Why use it?
It helps developers make controls understandable to people using assistive technology and easy for tests to find reliably.

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 12d 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mobile Accessibility (the shared trunk)

Why its own skill: the same tags serve two consumers (driving vs auditing); owning them here keeps both DRY. Driving skills read the handle; auditing skills read the semantics.

The model: one tree, two readers

An accessible app exposes an accessibility tree: a hierarchy of elements that assistive technology (VoiceOver) navigates, and that an automation driver (AXe) reads to find and tap things. Every element can carry a few fields. Two of them matter most, and they exist for different reasons:

Field (iOS) React Native prop Who reads it What it is for
accessibilityIdentifier testID the driver a stable handle to find an element in a script
accessibilityLabel accessibilityLabel the human (VoiceOver) and the auditor the element's name, spoken aloud

Apple draws this line itself: an identifier lets a script "uniquely identify an element" and thereby "avoid inappropriately setting or accessing an element's accessibility label" (accessibilityIdentifier docs). React Native's testID is the same idea from the other side: "Used to locate this view in end-to-end tests." The label, by contrast, is "a string that succinctly identifies the accessibility element" for a user; Apple's example is "Save," not "Save button."

So:

  • Driving wants the handle. Prefer testID -> accessibilityIdentifier; it does not change when copy, locale, or layout changes. Tapping by visible label is the fallback when no handle exists. Coordinates are the last resort (brittle; see ios-simulator references/driving.md).
  • Auditing wants the semantics: is there a label at all, is the role right, is the state (disabled, selected, checked) correct, is the focus order sane.

Where to go

  • iOS-native fields and how they surface to a driver: references/ios-native.md.
  • React Native / Expo props and the RN -> native mapping: references/react-native-expo.md.
  • The auditing lens (completeness, correctness): references/auditing.md.

What ships with it

3 files 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.

mobile-accessibility is a skill published in the GitHub repository simiancraft/simiancraft-skills (7 stars, last pushed 8d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 879 tokens. 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.
