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 | $0.00045 | $0.03270 |
| Opus 5 | $0.00023 | $0.01635 |
| Sonnet 5 | $0.00009 | $0.00654 |
| Haiku 4.5 | $0.00005 | $0.00327 |
Grade A, and why
wcag-audit-patterns 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 7d 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.

WCAG Audit Patterns
Comprehensive guide to auditing web content against WCAG 2.2 guidelines with actionable remediation strategies.
When to Use This Skill
- Conducting accessibility audits
- Fixing WCAG violations
- Implementing accessible components
- Preparing for accessibility lawsuits
- Meeting ADA/Section 508 requirements
- Achieving VPAT compliance
Core Concepts
1. WCAG Conformance Levels
| Level | Description | Required For |
|---|---|---|
| A | Minimum accessibility | Legal baseline |
| AA | Standard conformance | Most regulations |
| AAA | Enhanced accessibility | Specialized needs |
2. POUR Principles
Perceivable: Can users perceive the content?
Operable: Can users operate the interface?
Understandable: Can users understand the content?
Robust: Does it work with assistive tech?
3. Common Violations by Impact
Critical (Blockers):
├── Missing alt text for functional images
├── No keyboard access to interactive elements
├── Missing form labels
└── Auto-playing media without controls
Serious:
├── Insufficient color contrast
├── Missing skip links
├── Inaccessible custom widgets
└── Missing page titles
Moderate:
├── Missing language attribute
├── Unclear link text
├── Missing landmarks
└── Improper heading hierarchy
Audit Checklist
Perceivable (Principle 1)
## 1.1 Text Alternatives
### 1.1.1 Non-text Content (Level A)
- [ ] All images have alt text
- [ ] Decorative images have alt=""
- [ ] Complex images have long descriptions
- [ ] Icons with meaning have accessible names
- [ ] CAPTCHAs have alternatives
Check:
```html
<!-- Good -->
<img src="chart.png" alt="Sales increased 25% from Q1 to Q2" />
<img src="decorative-line.png" alt="" />
<!-- Bad -->
<img src="chart.png" />
<img src="decorative-line.png" alt="decorative line" />
```
1.2 Time-based Media
1.2.1 Audio-only and Video-only (Level A)
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.
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.

wcag-audit-patterns is a skill published in the GitHub repository fellipeutaka/leon (5 stars, last pushed 7d ago), licensed MIT. It adds 45 tokens to every session and 3,270 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 2026-09-03.
