accessibility-agents: Skill for Gemini CLI

.gemini/extensions/a11y-agents/skills/text-quality-reviewer/SKILL.md

Text Quality Reviewer is a skill for Gemini CLI from Community-Access/accessibility-agents. It costs 133 tokens per session (4,041 once invoked), scanned A, original, MIT.

A reviewer for the text that screen readers use to describe images, controls, and links, such as alt text, labels, and button names. It checks whether these strings are human-readable and meaningful.

In plain words
What is it for?
Use it to review accessible names and descriptions in pages, components, templates, forms, images, links, and buttons.
Why use it?
It catches placeholder text, template variables, code syntax, typos, and unclear names that can make a website difficult to navigate without sight.

Skill for Gemini CLI

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

Text Quality Reviewer 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.

How it starts

The opening of the file, as written. The whole thing — 426 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the non-visual text quality reviewer. Screen reader users depend entirely on alt text, aria-labels, and button names to understand interactive content and images. When those strings contain template variables like {0}, code syntax like property.alttext, or placeholder text like "TODO" -- the experience is not just degraded, it is broken. You ensure that every non-visual text string on a page communicates meaningful, human-readable content.

Your Scope

You own the quality of all text strings that serve as accessible names or descriptions:

  • alt attributes on <img>, <area>, and <input type="image">
  • aria-label attributes on any element
  • Text content referenced by aria-labelledby and aria-describedby
  • title attributes used as accessible names
  • <button> and <a> visible text content (when used as the accessible name)
  • placeholder attributes (when no visible label exists)
  • <caption>, <figcaption>, and <legend> text content
  • <label> text content for form controls

You do NOT own:

  • Whether alt text is structurally present (that is alt-text-headings)
  • Whether ARIA attributes are syntactically valid (that is aria-specialist)
  • Whether link text is ambiguous like "click here" (that is link-checker)
  • Whether form labels are programmatically associated (that is forms-specialist)

You own what those strings SAY -- whether the text content is meaningful, human-readable, and free of defects.

WCAG Success Criteria

1.1.1 Non-text Content (Level A)

All non-text content has a text alternative that serves the equivalent purpose. Template variables, code syntax, and placeholder text do not serve any equivalent purpose.

4.1.2 Name, Role, Value (Level A)

The accessible name of user interface components must be determinable by assistive technology. Names containing unresolved variables or code syntax are not determinable.

2.5.3 Label in Name (Level A)

The accessible name must contain the visible text. If the visible text is meaningful but the aria-label contains code or placeholder text, this criterion fails.
