Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00039 | $0.03336 |
| Opus 5 | $0.00019 | $0.01668 |
| Sonnet 5 | $0.00008 | $0.00667 |
| Haiku 4.5 | $0.00004 | $0.00334 |
Grade A, and why
a11y-audit 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.

<quick_start>
- Read HTML/Astro files for the page
- Audit against WCAG 2.1 Level A and AA criteria
- Check for common accessibility anti-patterns
- Generate structured pass/fail report
- Provide specific fixes for each violation </quick_start>
<wcag_2_1_requirements>
Level A (Critical - Must Pass)
| Criterion | Check | Implementation |
|---|---|---|
| 1.1.1 Non-text Content | All images have alt text | <img alt="Descriptive text"> |
| 1.3.1 Info and Relationships | Semantic HTML structure | Use <nav>, <main>, <article>, not just <div> |
| 1.3.2 Meaningful Sequence | Logical reading order | DOM order matches visual order |
| 2.1.1 Keyboard | All functionality via keyboard | No mouse-only interactions |
| 2.4.1 Bypass Blocks | Skip navigation link | First focusable element links to #main-content |
| 2.4.2 Page Titled | Descriptive <title> |
Unique, descriptive page title |
| 2.4.4 Link Purpose | Descriptive link text | No "click here" or "read more" alone |
| 3.1.1 Language of Page | <html lang> attribute |
<html lang="en"> or appropriate |
| 3.2.2 On Input | No unexpected context changes | Form inputs don't auto-submit |
| 4.1.1 Parsing | Valid HTML | No duplicate IDs, proper nesting |
| 4.1.2 Name, Role, Value | Proper ARIA or native elements | Buttons are <button>, not <div onclick> |
Level AA (Required - Must Pass)
| Criterion | Check | Implementation |
|---|---|---|
| 1.4.3 Contrast (Minimum) | 4.5:1 for normal text | Text vs background contrast |
| 1.4.3 Contrast (Minimum) | 3:1 for large text (18pt+) | Headings, large UI text |
| 1.4.5 Images of Text | Avoid text in images | Use real text with CSS styling |
| 2.4.5 Multiple Ways | Navigation + search/sitemap | At least two ways to find pages |
| 2.4.6 Headings and Labels | Descriptive headings/labels | Clear, informative text |
| 2.4.7 Focus Visible | Visible focus indicator | :focus-visible styles on all interactive elements |
| 3.1.2 Language of Parts | lang on foreign language sections |
<span lang="es">Hola</span> |
| 3.2.3 Consistent Navigation | Same nav order across pages | Header/footer structure consistent |
| 3.2.4 Consistent Identification | Same icons/labels for same functions | Search icon always means search |
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.

a11y-audit is a skill published in the GitHub repository solo-super/marketplace (2 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 3,336 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
