a11y-i18n

a11y-i18n is an agent for Claude Code from ncoevoet/claude-review-all. It costs 32 tokens per session (662 once invoked), scanned A, original, MIT.

A conditional review agent for user-interface changes, covering accessibility and internationalisation. Accessibility helps people with disabilities use the interface; internationalisation prepares it for multiple languages and regions.

In plain words
What is it for?
Use it when changed files contain web templates, interface components, or translation files.
Why use it?
It catches missing labels, keyboard support, alternative text, translation keys, and other issues that may exclude users or break translated interfaces.

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

a11y-i18n 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 8d 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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent 10: Accessibility & i18n (CONDITIONAL)

Only spawn this agent if changed files match UI patterns:

  • HTML / template files (.html, .tsx, .vue, .svelte)
  • Component files with inline templates
  • Translation files (en.json, messages.xlf, dev.json, etc.)

No files match → skip this agent.

Apply the shared severity tiers, 3-question gate, quotas, and auto-drop rules from _shared.md.

Inputs you receive: full diff, changed file list, Project Profile, CLAUDE.md rules, Phase 1 gate results.

Accessibility (WCAG-aligned, focused)

  • Interactive elements without accessible names: <button> / <a> with only icon, no aria-label / text
  • Form inputs without labels: <input> not associated with <label> (or aria-label / aria-labelledby)
  • Click handlers on non-interactive elements: <div (click)> / <span onClick> without keyboard handler / role
  • Color-only signals: error/success indicated only by color, no icon/text
  • Missing alt text on <img>: empty/missing alt on content images (decorative images need alt="")
  • Heading order skips: <h1> then <h3>
  • Focus traps missing on modals/dialogs, or focus not restored on close
  • Custom components missing role/aria for their pattern (combobox, listbox, tab, etc.)

Internationalization

  • Hardcoded user-facing strings in templates/components instead of translation keys
  • Translation keys referenced but not present in en.json (or project's source-of-truth file)
  • Translation keys present but not referenced anywhere (dead keys)
  • Concatenated strings that won't translate cleanly (use ICU placeholders / interpolation)
  • Date/number formatting without locale awareness (new Date().toString() vs Intl.DateTimeFormat)
  • Right-to-left: layout assumptions breaking in RTL (hardcoded padding-left, margin-right)

Project conventions

Check CLAUDE.md and Project Profile for project-specific i18n rules (source-of-truth file, propagation script, namespace patterns). Follow them — do not assume conventions from other projects.

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.
