accessibility-scan

accessibility-scan is a skill for Claude Code, Codex from AccessLint/skills. It costs 205 tokens per session (695 once invoked), scanned A, original, no licence file.

An automated accessibility check for one live web page using a rule engine and WCAG-based checks. WCAG is the main international standard for making websites usable by people with disabilities.

In plain words
What is it for?
Use it with a URL, a configured target, or the default project target to scan a page and locate automatically detectable violations.
Why use it?
It quickly finds accessibility violations that can be detected mechanically and provides a starting point for further review.

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-scan 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 5d 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.

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.
