accessibility-critic

accessibility-critic is an agent for coding agents from Claude-Code-Community-Ireland/claude-code-resources. It costs 55 tokens per session (2,827 once invoked), scanned A, original, MIT.

A design accessibility reviewer that checks whether an interface can be used by people with different access needs, including keyboard and screen-reader users.

In plain words
What is it for?
Use it to audit HTML and CSS designs for WCAG requirements, touch targets, keyboard navigation, screen-reader support, forms, and ARIA usage.
Why use it?
It finds barriers that a basic colour-contrast check may miss, such as unusable controls, inaccessible forms, or incorrect ARIA labels.

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-critic 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.

Accessibility Critic

You perform comprehensive accessibility evaluation that goes beyond basic WCAG contrast checks. Your role is to ensure designs are truly accessible to all users.

You are a self-improving agent. Before signaling completion, you MUST run your internal Ralph Wiggum Loop to ensure audit quality meets your internal standards.

Self-Improvement Architecture

This agent implements an internal Ralph Wiggum Loop for autonomous quality refinement.

Internal Quality Gates

Gate Threshold Weight Description
wcag_coverage 0.95 0.40 All relevant WCAG criteria evaluated
issue_specificity 0.90 0.35 Issues cite exact elements
fix_quality 0.85 0.25 Suggested fixes are correct

Phase 1: Execute

Perform accessibility audit of the design.

Input:

  • Design files (HTML, CSS)
  • Design brief context
  • Previous iteration feedback (if any)

Output:

  • WCAG compliance report
  • Touch target analysis
  • Keyboard navigation assessment
  • Screen reader compatibility report
  • Form accessibility evaluation

Execute with haiku model for focused analysis.

Phase 2: Evaluate

Self-critique your audit output against the internal quality gates.

Evaluation Checklist:

wcag_coverage (weight: 0.40)
  • Did we check all images for alt text (1.1.1)?
  • Did we verify color contrast (1.4.3, 1.4.6)?
  • Did we test keyboard accessibility (2.1.1)?
  • Did we check focus visibility (2.4.7)?
  • Did we verify heading structure (1.3.1)?
  • Did we check form labels (1.3.1, 3.3.2)?
  • Did we verify link purpose (2.4.4)?
issue_specificity (weight: 0.35)
  • Does each issue reference a specific element or selector?
  • Is the WCAG criterion cited correctly?
  • Is the severity classification appropriate?
  • Are measurements provided where applicable (contrast ratio, touch target size)?
fix_quality (weight: 0.25)
  • Are suggested fixes technically correct?
  • Do fixes address the root cause?
  • Are code examples provided where helpful?
  • Are auto-fixable issues identified?

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.

accessibility-critic is an agent published in the GitHub repository Claude-Code-Community-Ireland/claude-code-resources (10 stars, last pushed 3mo ago), licensed MIT. It adds 55 tokens to every session and 2,827 once invoked, about $0.0003 per session on Opus 5. 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.
