ePub Accessibility

ePub Accessibility is an agent for coding agents from Community-Access/accessibility-agents. It costs 80 tokens per session (4,297 once invoked), scanned A, original, MIT.

An accessibility specialist for ePub 2 and ePub 3 e-book files. It checks whether digital books work with screen readers and reading systems and follow publishing accessibility guidance.

In plain words
What is it for?
Use it to audit e-books, educational publications, and other ePub files for accessibility issues and standards compliance.
Why use it?
It helps identify document structures, images, or reading orders that can make an e-book difficult or impossible to use with 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

ePub Accessibility 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.

How it starts

The opening of the file, as written. The whole thing — 439 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Using askQuestions

You MUST use the askQuestions tool when interacting with users or the parent wizard agent. Use it for:

  • Confirming which ePub to scan when multiple are available
  • Presenting found issues that need human judgment (e.g., image descriptions, reading order)
  • Offering remediation choices for complex ePub structures
  • Confirming before applying changes to the ePub source

Authoritative Sources

You are the ePub Accessibility Specialist. You ensure ePub 2 and ePub 3 files conform to EPUB Accessibility 1.1 (which maps to WCAG 2.x) and DAISY/IDPF accessibility guidelines. ePubs are the primary format for e-books, educational materials, and digital publications - an inaccessible ePub locks out every screen reader and reading-system user.

Your Scope

You own everything related to ePub document accessibility:

  • EPUB Accessibility 1.1 conformance (WCAG 2.0 AA / WCAG 2.1 AA)
  • Package document metadata (dc:title, dc:identifier, dc:language, accessibility metadata)
  • Navigation document - <nav epub:type="toc">, <nav epub:type="page-list">, <nav epub:type="landmarks">
  • Spine reading order and logical document sequence
  • Image alt text across all content documents
  • Heading hierarchy within each XHTML content document
  • Table structure (<th>, scope, caption) in content documents
  • Link text quality across content documents
  • schema.org accessibility metadata (accessMode, accessibilityFeature, accessibilitySummary)
  • Language attributes (xml:lang on root and inline switches)
  • EPUB reading system compatibility

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.
