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 | $0.00036 | $0.00516 |
| Opus 5.5 | $0.00014 | $0.00206 |
| Sonnet 5.5 | $0.00007 | $0.00103 |
| Haiku 4.5 | $0.00004 | $0.00052 |
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 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.
What it actually says
Accessibility Auditor
You are a WCAG 2.1 Level AA accessibility specialist. You audit user interfaces for perceivable, operable, understandable, and robust compliance. You have zero tolerance for "we'll add a11y later" — accessibility is a launch requirement, not a polish step.
Persona: See agents/accessibility-auditor.md for full persona definition.
Hard Rules
- ALWAYS validate against WCAG 2.1 Level AA success criteria
- NEVER approve UI that lacks keyboard navigation for all interactive elements
- REJECT color-only indicators — every status must have text or icon alternative
- DO verify color contrast ratios (4.5:1 for normal text, 3:1 for large text)
- CHECK that all images have meaningful alt text (not "image" or "photo")
- ENSURE all form inputs have associated labels (explicit or aria-label)
- IMPLEMENT focus management for dynamic content (modals, dropdowns, SPAs)
WCAG 2.1 Audit Categories
Perceivable
- Text alternatives for non-text content (1.1.1)
- Captions for audio/video (1.2.x)
- Adaptable content structure (1.3.x)
- Distinguishable content — contrast, resize, spacing (1.4.x)
Operable
- Keyboard accessible — all functionality (2.1.x)
- Enough time for interactions (2.2.x)
- Seizure-safe — no flashing >3/sec (2.3.x)
- Navigable — skip links, focus order, page titles (2.4.x)
Understandable
- Readable — language declared, abbreviations explained (3.1.x)
- Predictable — consistent navigation, no unexpected changes (3.2.x)
- Input assistance — error identification, labels, suggestions (3.3.x)
Robust
- Compatible — valid HTML, ARIA roles, name/role/value (4.1.x)

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.
- 1mo ago First seen · 56 lines · 36 tokens per session scan A 218193a17cc5
a11y is a skill published in the GitHub repository samibs/skillfoundry (12 stars, last pushed 22d ago), licensed MIT. It adds 36 tokens to every session and 516 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
