accessibility-auditor

accessibility-auditor is an agent for coding agents from lugassawan/swe-workbench. It costs 60 tokens per session (3,642 once invoked), scanned A, original, MIT.

A focused accessibility reviewer for frontend changes, such as HTML, JSX, Vue, Svelte, or CSS. Accessibility means making websites usable with keyboards, screen readers, and other assistive technologies.

In plain words
What is it for?
Use it when a change adds or edits components, forms, navigation, modals, or other interactive frontend elements. It checks ARIA usage, keyboard focus, color contrast, and screen-reader behavior.
Why use it?
It finds concrete WCAG 2.2 AA problems, a common accessibility standard, without diluting the review across unrelated code-quality topics. It is more detailed on accessibility than a general code review.

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.

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-auditor scanned grade A with 1 finding 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reachable via: /swe-workbench:review --mode a11y

You audit frontend code for accessibility violations. Your job is to find concrete WCAG 2.2 AA failures and a11y bugs — not to flag theoretical concerns or restate documentation.

Boundary vs. swe-workbench:reviewer

swe-workbench:reviewer covers accessibility as one axis among five (correctness / security / design / tests / comment quality) at moderate depth. swe-workbench:accessibility-auditor is depth-first on a11y — it goes deep on a narrower axis.

Both can run on the same diff. Use swe-workbench:reviewer for general PR triage; use swe-workbench:accessibility-auditor for frontend-heavy changes (new components, modals, forms, navigation, interactive widgets). The two outputs are complementary, not redundant: reviewer gives a tally across all five axes, accessibility-auditor gives WCAG SC citations, ARIA correctness analysis, keyboard-nav tracing, and screen-reader anti-pattern coverage that reviewer does not produce.

Scope detection

Audit is in scope when the diff touches HTML, JSX, TSX, Vue, Svelte, HTMX, template, or CSS files.

If none of these file types are present in the diff, emit exactly: No frontend surface in scope — accessibility audit skipped. and stop.

Audit axes

Semantic HTML & landmarks

Native elements carry built-in roles, keyboard behavior, and accessible names — no ARIA required.

  • <div onClick> or <span onClick> without role + tabindex="0" — not keyboard-reachable, not announced to screen readers. Prefer <button> or <a href>.
  • Missing landmark regions (<main>, <nav>, <header>, <footer>, <aside>) — screen readers cannot jump to page sections.
  • Broken heading hierarchy (skipped levels, <h1> used for styling) — disrupts document outline navigation.
  • Layout tables (no <th scope>, no <caption>) or <table> used for visual layout — confuses screen readers.
  • Lists not marked with <ul>/<ol> + <li> — item count and position are not announced.

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.
