design-accessibility

design-accessibility is an agent for Claude Code from ZachArticulateV/designer-pro-and-seo. It costs 101 tokens per session (1,403 once invoked), scanned A, original, MIT.

A WCAG 2.2 accessibility audit checks whether HTML follows common web-accessibility requirements. WCAG is a set of guidelines for making websites usable by people with disabilities.

In plain words
What is it for?
Use it to inspect a URL or HTML for accessibility issues, rank findings by severity, connect them to WCAG criteria, and get concrete fixes.
Why use it?
It finds structural barriers such as missing image descriptions, labels, headings, language information, landmarks, and skip links before they affect users.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

design-accessibility 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 12d 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.

Wraps: skills/design-accessibility/SKILL.md — same method, no forked logic.

Method

Audit HTML against WCAG 2.2 the same way the skill does: run the bundled structural checker on the page source, then classify every finding by severity with its success criterion and a concrete remediation. Computed-contrast, live keyboard/focus, reduced-motion, and 200%-zoom facts belong to the rendered axe scan (Tier 1) and are never synthesized from the static pass.

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/design/a11y_static.py" --file <page.html> --human   # or --html <string>

It emits severity-ranked JSON for image alt coverage, heading order (no skipped levels / a single <h1>), form-control labels, <html lang>, a skip-to-content link, <main>/landmark presence, and a responsive (non-zoom-blocking) viewport meta. When a design-system-gen token file is present, add --tokens <tokens.json> for the token-contrast cross-check — the engine's own WCAG luminance math over the text/bg/surface/primary/on_primary/accent slots (4.5:1 body / 3:1 UI). Group findings critical / serious / moderate / minor, each naming its WCAG SC and a specific fix (file:line when the source is available).

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.
