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 | $0.00074 | $0.02357 |
| Opus 5 | $0.00037 | $0.01179 |
| Sonnet 5 | $0.00015 | $0.00471 |
| Haiku 4.5 | $0.00007 | $0.00236 |
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 12d 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
WCAG 2.2 Accessibility Audit and Remediation Skill
Description
The a11y-audit skill provides a complete accessibility audit pipeline for modern web applications. It implements a three-phase workflow -- Scan, Fix, Verify -- that identifies WCAG 2.2 Level A and AA violations, generates exact fix code per framework, and produces stakeholder-ready compliance reports.
For every violation it finds, it provides the precise before/after code fix tailored to your framework (React, Next.js, Vue, Angular, Svelte, or plain HTML).
What this skill does:
- Scans your codebase for every WCAG 2.2 Level A and AA violation, categorized by severity (Critical, Major, Minor)
- Fixes each violation with framework-specific before/after code patterns
- Verifies that fixes resolve the original violations and introduces no regressions
- Reports findings in a structured format suitable for developers, PMs, and compliance stakeholders
- Integrates into CI/CD pipelines to prevent accessibility regressions
Features
| Feature | Description |
|---|---|
| Full WCAG 2.2 Scan | Checks all Level A and AA success criteria across your codebase |
| Framework Detection | Auto-detects React, Next.js, Vue, Angular, Svelte, or plain HTML |
| Severity Classification | Categorizes each violation as Critical, Major, or Minor |
| Fix Code Generation | Produces before/after code diffs for every issue |
| Color Contrast Checker | Validates foreground/background pairs against AA and AAA ratios |
| Compliance Reporting | Generates stakeholder reports with pass/fail summaries |
| CI/CD Integration | GitHub Actions, GitLab CI, Azure DevOps pipeline configs |
| Keyboard Navigation Audit | Detects missing focus management and tab order issues |
| ARIA Validation | Checks for incorrect, redundant, or missing ARIA attributes |
Severity Definitions
| Severity | Definition | Example | SLA |
|---|---|---|---|
| Critical | Blocks access for entire user groups | Missing alt text, no keyboard access to navigation | Fix before release |
| Major | Significant barrier that degrades experience | Insufficient color contrast, missing form labels | Fix within current sprint |
| Minor | Usability issue that causes friction | Redundant ARIA roles, suboptimal heading hierarchy | Fix within next 2 sprints |

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 bestagentkits/agency-skills (11 stars, last pushed 2mo ago), licensed MIT. It adds 74 tokens to every session and 2,357 once invoked, about $0.0004 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.
