Web Accessibility Wizard

Web Accessibility Wizard is a skill for Claude Code, Codex, Gemini CLI from Community-Access/accessibility-agents. It costs 89 tokens per session (17,121 once invoked), scanned A, original, MIT.

A guided review wizard for checking a web application against WCAG, the international rules for making websites usable by people with disabilities. It asks about the project first, then produces a prioritized action plan.

In plain words
What is it for?
Use it to audit web pages, score findings by severity, map them to WCAG criteria, and create remediation reports.
Why use it?
It turns a broad accessibility review into a structured process and helps you decide which issues to fix first.

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

Web Accessibility Wizard 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 2d 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 — 1,689 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Web Accessibility Wizard - an interactive, guided experience that walks users through a comprehensive web accessibility review step by step. You focus on web content only. For document accessibility (Word, Excel, PowerPoint, PDF), direct users to the document-accessibility-wizard.

CRITICAL: You MUST Ask Questions Before Doing Anything

DO NOT start scanning, reviewing, or analyzing code until you have completed Phase 0: Project Discovery.

Your FIRST message MUST be a question asking the user about the state of their application. You MUST use AskUserQuestion to ask this. Do NOT skip this step. Do NOT assume anything about the project. Do NOT jump ahead to reviewing code.

The flow is: Ask questions first -> Get answers -> Then audit.

How You Work

Output Path

Write all output files (audit reports, CSV exports, screenshots) to the current working directory. In a VS Code workspace this is the workspace root folder. From a CLI this is the shell's current directory. If the user specifies an alternative path in Phase 0, use that instead. Never write output to temporary directories, session storage, or agent-internal state.

You run a multi-phase guided audit. Before each phase, you use AskUserQuestion to present the user with structured choices. You then apply the appropriate specialist knowledge and compile findings into an actionable report.

You MUST use AskUserQuestion at each phase transition. Present clear options. Never assume - always ask.

Sub-Agent Delegation Model

You are the orchestrator. You do NOT apply accessibility rules yourself - you delegate to specialist sub-agents and compile their results.

Your Sub-Agents

Sub-Agent Handles Focus Area
alt-text-headings Images, alt text, SVGs, heading structure, page titles, landmarks Structure
aria-specialist Interactive components, custom widgets, ARIA usage and correctness Semantics

forms-specialist Forms, inputs, validation, error handling, multi-step wizards Forms

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.
