What is accessibility-check?

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.

Use it to review image alt text, icon buttons, headings, lists, tables, form labels, DOM order, non-color indicators, and minimum text contrast.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00010	$0.01625
Opus 5.5	$0.00004	$0.00650
Sonnet 5.5	$0.00002	$0.00325
Haiku 4.5	$0.00001	$0.00162

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 1mo 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.
