accessibility-agent is an agent for Claude Code from navikt/copilot. It costs 32 tokens per session (2,308 once invoked), scanned A, original, MIT.

An agent for checking web accessibility against WCAG 2.1 and 2.2, guidelines for making websites usable by people with disabilities, with attention to Norway's Aksel design system and legal requirements.

In plain words
What is it for?
Use it to review semantic HTML, ARIA, keyboard navigation, focus handling, colour contrast, screen-reader support, and automated tests with tools such as axe-core, Lighthouse, and Playwright.
Why use it?
It helps find barriers that can prevent people from using an application with a keyboard, screen reader, zoom, or different colour settings. It also reduces the need to check these issues manually.

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-agent 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 17d 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.
