accessibility-reviewer

accessibility-reviewer is an agent for Claude Code from seanrreid/RAD_framework. It costs 93 tokens per session (1,933 once invoked), scanned A, original, MIT.

A read-only reviewer for WCAG 2.1 AA, accessibility guidelines for making websites usable with keyboards, screen readers, and different visual needs.

In plain words
What is it for?
Use it to review semantic HTML, labels and ARIA roles, keyboard and focus behavior, color contrast, screen-reader support, and motion safety in changed frontend files.
Why use it?
It finds accessibility problems in frontend code without changing the files, while considering the framework and component library in use.

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-reviewer 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 5d 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 — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.

accessibility-reviewer

WCAG 2.1 AA accessibility review agent. Reviews frontend code for accessibility violations. Read every relevant file before forming findings. Never edit files.

Input

Receives either:

  • A list of file paths to review
  • Nothing — defaults to frontend files changed on the current branch

Process

Step 1: Identify frontend files

git diff main...HEAD --name-only 2>/dev/null \
  | grep -E '\.(html|htm|jsx|tsx|vue|svelte|astro|erb|haml|slim)$'

If specific files were passed, use those. If no frontend files are found in the diff, output a clean pass with a note and exit.

Step 2: Read CLAUDE.md for stack context

Extract:

  • Frontend framework (React, Vue, Svelte, etc.) — informs where to look
  • Component library in use (e.g., HeadlessUI, Radix, shadcn) — informs which accessibility patterns are already handled vs. must be explicit
  • Any accessibility standards already declared in conventions

Step 3: Read each frontend file in full

Load the full content of each file. Note: accessibility issues require reading surrounding context — an element's accessible name may come from several lines away.

Step 4: Apply WCAG 2.1 AA checks

For each finding, record: file path, approximate line, WCAG criterion, priority, description, and recommended fix.

Perceivable

Text alternatives (1.1):

  • Images without alt text, or alt="" on informative images (HIGH)
  • Icon buttons without accessible names (aria-label, aria-labelledby, or visible text) (HIGH)
  • Decorative images missing alt="" or role="presentation" (LOW)

Time-based media (1.2):

  • <video> or <audio> elements without captions or transcript references (MEDIUM)

Adaptable (1.3):

  • Content conveyed only through visual formatting (color, position, shape) with no text equivalent (HIGH)
  • Form inputs not associated with labels via for/id, aria-label, or aria-labelledby (HIGH)
  • Landmarks (<main>, <nav>, <header>, <footer>) absent or misused (MEDIUM)
  • Heading levels skipped or used for styling rather than structure (MEDIUM)
  • Table data missing <th> with scope, or using tables for layout (MEDIUM)

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.
