accessibility-gate

accessibility-gate is a skill for Claude Code, Codex from vmobifystudio/app-dev-team. It costs 74 tokens per session (636 once invoked), scanned A, original, MIT.

Use as a pass/fail gate on any diff with a user-facing surface — by code-reviewer during review, by qa-engineer during the test pass, and by any IC before claiming a UI ticket done. This is the gate the plan called for instead of an accessibility specialist role. Triggers whenever a screen, component or state changes.

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

accessibility-gate 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 today.

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

Accessibility gate

The studio's position, from the plan: accessibility does not need a specialist role, it needs a gate that can fail. This is that gate. It runs on the diff, not on the finished app, because a retrofit is an order of magnitude more expensive than doing it in the ticket.

Where a platform auditor exists, spawn it first and fold its findings in — axiom:accessibility-auditor on iOS, ui-design:accessibility-audit elsewhere. Both are external and optional (separate plugins, not this one's skills/). Missing → record N/A: <tool> — not installed, walk the list by hand, never file the absence as a defect.

The gate

Each item is PASS or FAIL: <what and where>. There is no partial credit and no "minor".

  1. Every interactive element has an accessible label that says what it does — not its icon name. An unlabelled icon button is a control that does not exist for a screen-reader user.
  2. Reading order matches visual order, and grouped content is grouped for the screen reader too.
  3. Every state change is announced — loading finished, error appeared, item deleted. A silent state change strands the user in the previous screen.
  4. Touch targets are at least 44pt (iOS) / 48dp (Android), including in dense lists.
  5. Contrast: 4.5:1 body text, 3:1 large text and non-text indicators. Checked against the token, in both light and dark.
  6. Colour is never the only signal. Error, selection and status carry a shape, an icon or text.
  7. Dynamic Type / font scaling to the largest supported size does not clip, truncate meaning, or overlap. Test at the maximum, not at 120%.
  8. Keyboard and switch access reach every action, focus is always visible, and focus is never trapped. On web this includes a skip link and a visible :focus-visible style.
  9. Reduce-motion is honoured and still gives the user feedback (interaction-motion).
  10. Media has an alternative — alt text, caption, or transcript.

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.
