a11y-audit

a11y-audit is a skill for Claude Code from greglas75/zuvo. It costs 147 tokens per session (8,904 once invoked), scanned A, original, MIT.

An accessibility audit that checks a website or codebase against WCAG 2.2, the international guidelines for making digital products usable by people with disabilities. It covers areas such as keyboard use, screen-reader structure, contrast, forms, images, motion, and responsive behavior.

In plain words
What is it for?
Use it to audit a component, directory, or full project, optionally test a live URL, limit checks to critical areas, choose AA or AAA criteria, and generate fixes.
Why use it?
It finds accessibility barriers and links each finding to a specific guideline and severity, helping teams address compliance and usability risks before launch.

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-audit 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 7d 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.

zuvo:a11y-audit — WCAG 2.2 Accessibility Audit

Deep, compliance-focused accessibility audit across 10 weighted dimensions with WCAG 2.2 criterion mapping, legal risk assessment, and actionable fix generation. Every finding maps to a specific WCAG success criterion and severity level.

When to use: Before public launches, when targeting WCAG compliance, after ADA/EAA legal requirements surface, periodic accessibility health checks, when onboarding a codebase that must meet compliance standards, after adding interactive components or forms. Out of scope: Surface-level design consistency (zuvo:design-review), visual design quality (zuvo:ui-design-team), code quality (zuvo:code-audit), penetration testing (zuvo:pentest).

Argument Parsing

Parse $ARGUMENTS for these flags:

Argument Effect
[path] Audit a specific directory or component
full Audit the entire project
--live-url <url> Enable browser-based testing (axe-core via MCP)
--quick Critical gates only (A2 Keyboard, A4 Contrast)
--fix Generate fix code for all findings
--standard AA|AAA Compliance level (default: AA)
--legal ada|eaa|508 Focus on a specific legal standard
--max-files [N] Cap audit to N files (default: 40)
--persist-backlog Emit backlog entries for CRITICAL/HIGH findings
Mode Scope Phases Browser
[path] Directory/component 0-5 No
full Entire project 0-5 No
--live-url Project + URL 0-5 incl. Phase 2 browser Yes
--quick Project 0, 1 (A2+A4 only), 5 No

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.
