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 | $0.00045 | $0.03314 |
| Opus 5 | $0.00023 | $0.01657 |
| Sonnet 5 | $0.00009 | $0.00663 |
| Haiku 4.5 | $0.00005 | $0.00331 |
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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 509 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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)
- Audio has text transcript
- Video has audio description or transcript
1.2.2 Captions (Level A)
- All video has synchronized captions
- Captions are accurate and complete
- Speaker identification included
1.2.3 Audio Description (Level A)
- Video has audio description for visual content
1.3 Adaptable
1.3.1 Info and Relationships (Level A)
- Headings use proper tags (h1-h6)
- Lists use ul/ol/dl
- Tables have headers
- Form inputs have labels
- ARIA landmarks present
Check:
<!-- Heading hierarchy -->
<h1>Page Title</h1>
<h2>Section</h2>
<h3>Subsection</h3>
<h2>Another Section</h2>
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 EngineerWithAI/engineerwith-agents (4 stars, last pushed 7mo ago), licensed MIT. It adds 45 tokens to every session and 3,314 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.
