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 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 1mo 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

Baseline: WCAG 2.1 AA

Every user-facing interface must meet WCAG 2.1 Level AA. This is not optional — it's a legal requirement in many jurisdictions and the right thing to do.

Semantic HTML

Use the correct element, not a styled div:

  • <button> for actions (not <div onClick>)
  • <a> for navigation (not <span onClick>)
  • <nav> for navigation regions
  • <main> for primary content
  • <header>, <footer>, <section>, <article> for document structure
  • <h1>-<h6> in proper order (no skipping levels)
  • <ul>/<ol> for lists
  • <table> for tabular data (not for layout)

ARIA Labels

  • Every interactive element needs an accessible name
  • aria-label for elements without visible text
  • aria-labelledby to reference visible text
  • aria-describedby for additional context
  • aria-hidden="true" for decorative elements
  • Never use ARIA when native HTML semantics suffice

Color and Contrast

  • Text contrast ratio: 4.5:1 minimum (3:1 for large text)
  • Never convey information through color alone (add icons, text, patterns)
  • Ensure focus indicators are visible against all backgrounds

Keyboard Navigation

  • Every interactive element reachable via Tab
  • Logical tab order (follows visual layout)
  • Escape closes modals/popups
  • Enter/Space activates buttons
  • Arrow keys for menus, tabs, and lists
  • Visible focus indicator on all interactive elements

Images

  • Meaningful images: alt text describing the content
  • Decorative images: alt="" (empty alt, not missing alt)
  • Complex images (charts, diagrams): detailed aria-describedby

Forms

  • Every input has a <label> (linked via for/id)
  • Error messages linked to inputs via aria-describedby
  • Required fields marked with aria-required="true"
  • Form validation errors announced to screen readers

Focus Management

  • When modals open, focus moves to the modal
  • When modals close, focus returns to the trigger
  • Focus trapped inside modals (can't tab to background)
  • Route changes announce the new page to screen readers

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.
