What is it for?
Use it after building a UI or before release to inspect a page or component and report accessibility gaps.

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 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/a11y

An accessibility audit that reports gaps against WCAG 2.2 AA. /a11y reports; it does not auto-fix — fixes touch design and semantics and belong in a follow-up with the implementer. Pairs with the accessibility-auditor agent for deeper work.

When to use

After building any UI component; when the user says "check accessibility", "a11y audit", "WCAG check"; on /a11y; before a release that ships UI.

Commands

  • /a11y — audit the current page/component in context.
  • /a11y <route|component> — audit a specific surface.
  • /a11y update — re-audit after fixes, mark what's now resolved.

Step 1 — Detect the surface

  • Read the component(s) / route(s) in scope. If unclear, ask once which surface.
  • Detect the audit tools available (axe, lighthouse, keyboard) and use them; do not require a tool that isn't installed.

Step 2 — Audit against these checks

  • Keyboard — every action reachable and operable via keyboard; visible focus; logical tab order; no keyboard traps.
  • ARIA — roles only where semantics are missing; aria-label / aria-labelledby on icon-only / ambiguous controls; live regions for dynamic updates.
  • Labels & names — every input has a visible label; every interactive element has an accessible name.
  • Contrast — text ≥ 4.5:1 (normal), ≥ 3:1 (large); UI components / graphical objects ≥ 3:1.
  • Landmarksheader, nav, main, footer, search present and unique; one main.
  • Forms — error messages associated with fields; no placeholder-as- label; required fields indicated programmatically.
  • Motion & mediaprefers-reduced-motion respected; captions / transcripts for media.

Step 3 — Report

For each gap: WCAG criterion, the failing element, and a one-line fix suggestion. Group by severity (blocking vs non-blocking).

Output

## a11y audit — <surface>

### Blocking (WCAG 2.2 AA)
- <criterion> — <element> — fix: <one line>

### Non-blocking
- <criterion> — <element> — fix: <one line>

### Passed
- Keyboard nav, landmarks, contrast (normal text)

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.
