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

accessibility-auditor 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 11d 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.

Accessibility Auditor

Scan web application source code for WCAG 2.1 accessibility violations and produce a prioritized remediation report.

Workflow

  1. Discover UI components and templates Find all files containing HTML, JSX, TSX, Vue, Svelte:

    find . -maxdepth 5 \( -name "*.tsx" -o -name "*.jsx" -o -name "*.vue" -o -name "*.svelte" -o -name "*.html" \) -not -path "*/node_modules/*" -not -path "*/.next/*" | head -100

    Prioritize: layouts, navigation, forms, interactive widgets, media components.

  2. Check images and media (WCAG 1.1.1)

    • <img> without alt — Critical
    • Icon-only buttons without accessible labels — Critical
    • SVG without role="img" and aria-label — Major
    • <video>/<audio> without captions — Major

  3. Check semantic HTML (WCAG 1.3.1)

    • <div onClick> instead of <button> — Critical
    • Missing landmark elements (<nav>, <main>, <aside>)
    • Heading levels that skip (h1 → h3)
    • Inputs without associated <label>

  4. Check ARIA usage (WCAG 4.1.2)

    • Interactive elements without accessible names
    • aria-hidden="true" on focusable elements — Critical
    • Missing roles on custom widgets (tabs, dialogs, accordions)
    • Missing state attributes (aria-expanded, aria-selected)

  5. Check keyboard navigation (WCAG 2.1.1)

    • Custom controls without tabIndex
    • Missing onKeyDown handlers on custom interactive elements
    • outline: none without replacement focus style
    • Keyboard traps in modals

  6. Check focus management (WCAG 2.4.3)

    • Modals without focus trapping
    • Missing skip navigation link
    • Route changes without focus management

  7. Check color contrast (WCAG 1.4.3)

    • Low-contrast text/background combinations
    • Information conveyed by color alone
    • Common Tailwind pitfalls: text-gray-400 on bg-white = 2.7:1 (fails AA)

  8. Check forms (WCAG 3.3.1)

    • Inputs without labels
    • Placeholder as only label — Major
    • Error messages not linked via aria-describedby

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
