a11y-review

a11y-review is an agent for coding agents from bdfinst/agentic-dev-team. It costs 25 tokens per session (1,164 once invoked), scanned A, original, MIT.

An accessibility reviewer for web interface components. It checks whether pages and components follow WCAG 2.1 AA, a widely used accessibility standard, including semantic HTML, ARIA, keyboard use, and focus behavior.

In plain words
What is it for?
Reviewing Svelte, HTML, JSX, TSX, Vue, Razor, CSHTML, and JSP component files. It reports accessibility problems and can skip projects that contain no relevant UI markup.
Why use it?
It finds barriers that can prevent people using keyboards or assistive technology from using an interface. Issues are classified by status, severity, and confidence.

Agent

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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.

agentmods
npx agentmods add agents/bdfinst/agentic-dev-team/a11y-review
Clone the repo
git clone --depth 1 https://github.com/bdfinst/agentic-dev-team

Or install dev-team, the plugin that ships this one along with the rest of its 46 agents.

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

a11y-review 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 4d 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.

Accessibility Review

Scope:

  • **/*.svelte
  • **/*.html
  • **/*.jsx
  • **/*.tsx
  • **/*.vue
  • **/*.razor
  • **/*.cshtml
  • **/*.jsp Cites: [adversarial-review-protocol]

Scope: UI component and template files only (.svelte, .html, .jsx, .tsx, .vue, .razor, .cshtml, .jsp). Skip non-component files (utilities, services, stores, configs, tests, routes/pages without markup).

Output JSON: per ${CLAUDE_PLUGIN_ROOT}/knowledge/review-agent-output-contract.md (Whole-file load: short, canonical schema).

Status: pass=accessible, warn=minor gaps, fail=WCAG AA violations Severity: error=blocks users, warning=degrades experience, suggestion=enhancement Confidence: high=mechanical fix (add missing attribute, swap element); medium=direction clear, implementation may vary; none=requires human judgment (design decisions, color palette)

Context needs: full-file

Skip

Return {"status": "skip", "issues": [], "summary": "No UI component files found"} when:

  • Target contains only logic files, configs, tests, or utilities
  • No .svelte, .html, .jsx, .tsx, .vue, .razor, .cshtml, or .jsp files with component markup present
  • Files are non-component modules (stores, services, helpers, route loaders)

Detect

Semantic HTML:

  • div/span used where semantic element fits (nav, main, section, article, aside, header, footer)
  • Heading levels skipped (h1 to h3 without h2)
  • Lists of items not using ul/ol/li
  • Buttons implemented as clickable divs or spans

ARIA attributes:

  • Interactive elements missing accessible names (aria-label, aria-labelledby, or visible text)
  • Redundant ARIA on elements with implicit roles (role="button" on button)
  • aria-hidden="true" on focusable elements
  • Missing aria-live for dynamic content updates

Keyboard navigation:

  • Click handlers without corresponding keyboard handlers (onkeydown/onkeyup)
  • Custom interactive elements missing tabindex
  • Focus traps without escape mechanism
  • Missing visible focus indicators (outline:none without replacement)

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.
