accessibility-check

accessibility-check is a command for Claude Code from nyldn/claude-dolphin. It costs 10 tokens per session (1,625 once invoked), scanned A, original, MIT.

A focused check of a web component or file against WCAG 2.2 AA, a widely used accessibility standard. It reviews alternatives for images, semantic structure, reading order, link and error indicators, and text contrast.

In plain words
What is it for?
Use it to review image alt text, icon buttons, headings, lists, tables, form labels, DOM order, non-color indicators, and minimum text contrast.
Why use it?
It helps identify barriers that can prevent people with disabilities from using a website. The checklist turns accessibility requirements into specific code checks.

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-check 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 6d 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.

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.
