screen-reader-testing

screen-reader-testing is a skill for Claude Code, Codex from is-bo/fullstack-forge-skill. It costs 39 tokens per session (2,897 once invoked), scanned A, a copy of screen-reader-testing, Apache-2.0.

A practical guide for checking whether websites work with screen readers such as VoiceOver, NVDA, JAWS, and TalkBack. Screen readers read page content and controls aloud or through a refreshable display for people who cannot rely on sight.

In plain words
What is it for?
Use it to test web applications with screen readers, validate forms and dynamic content, debug accessibility problems, and check support across desktop and mobile platforms.
Why use it?
It helps find problems with keyboard focus, forms, navigation, dynamic updates, and ARIA, which is the HTML information used by assistive technology.

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

screen-reader-testing 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 2d 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.

Origin
