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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00113 | $0.02441 |
| Opus 5.5 | $0.00045 | $0.00976 |
| Sonnet 5.5 | $0.00023 | $0.00488 |
| Haiku 4.5 | $0.00011 | $0.00244 |
Grade A, and why
accessibility-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 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 Audit
Run a thorough accessibility audit and produce a remediation plan. Stack-agnostic. Anchored to WCAG 2.1 AA, with notes on AAA where relevant.
This skill goes deeper than the accessibility checks in qa-testing and design-standards. Use this when accessibility itself is the goal.
When to use
- Pre-launch accessibility verification
- Compliance preparation (ADA, EN 301 549, AODA, Section 508)
- Remediation after an audit finding or complaint
- Annual or quarterly accessibility health check
- Onboarding accessibility into a team that hasn't prioritized it before
When NOT to use
- General QA after deploys (use
qa-testing) - Component-level accessibility implementation (use
frontend-component-build) - Color contrast for design tokens (use
design-standardsorbrand-identity)
Required inputs
- The site or product under audit
- The scope (full site, specific section, specific user flow)
- The target standard (WCAG 2.1 AA is most common)
- Any specific concerns or known issues
- Tools available (automated scanners, screen readers, manual testing)
The framework: WCAG's 4 principles
WCAG organizes accessibility around four principles. The audit covers each in depth.
1. Perceivable
Information and UI must be presentable in ways users can perceive.
Audit checks:
- Text alternatives. All non-decorative images have descriptive
alttext. Decorative images usealt="". Complex images (charts, infographics) have long descriptions. - Time-based media. Videos have captions. Pre-recorded audio has transcripts. Live audio has live captions where required.
- Adaptable. Content structure is conveyed through markup (semantic HTML), not just visual styling. Reading order makes sense when CSS is disabled.
- Distinguishable. Color is not the sole means of conveying information. Text contrast meets AA (4.5:1 normal, 3:1 large). UI element contrast meets 3:1. Audio can be paused, stopped, or muted.
What ships with it
4 files 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.

accessibility-audit is a skill published in the GitHub repository rampstackco/claude-skills (992 stars, last pushed 5d ago), licensed MIT. It adds 113 tokens to every session and 2,441 once invoked, about $0.0005 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.
