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 | $0.00048 | $0.01958 |
| Opus 5 | $0.00024 | $0.00979 |
| Sonnet 5 | $0.00010 | $0.00392 |
| Haiku 4.5 | $0.00005 | $0.00196 |
Grade A, and why
a11y-audit-react 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 11d 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.

Skill: Accessibility Audit (React)
Purpose
Identify accessibility violations in React components and provide actionable remediation steps aligned with WCAG 2.2 Level AA.
Inputs
targetPath: Path to component file(s) or directory to audit.auditScope:single-file,directory, orfull-project.
Outputs
- Summary of violations with severity (critical, serious, moderate, minor).
- Actionable code fixes with minimal diffs.
- Verification commands to test changes.
Procedure
Step 1: Validate Scope
- Verify
targetPathexists. - Determine file(s) to audit based on
auditScope. - Filter for
.tsxand.jsxfiles.
Step 2: Run Automated Lint
Execute: .agents/skills/a11y-automation/scripts/run-a11y-lint.sh <targetPath>
Capture output.
If eslint-plugin-jsx-a11y is configured, parse violations.
Step 3: Load WCAG Guidelines
Read: .agents/skills/react-components/references/a11y-wcag22.md
Use as reference for manual inspection.
Step 4: Analyze Each Component
For each component file:
-
Semantic HTML Check
- Detect use of
<div>or<span>for buttons/links. - Flag missing landmarks (
<header>,<nav>,<main>,<footer>).
- Detect use of
-
Keyboard Navigation Check
- Verify interactive elements have
onClickandonKeyDownhandlers. - Check for keyboard traps in modals or focus-managed sections.
- Verify interactive elements have
-
ARIA Usage Check
- Identify missing
aria-labeloraria-labelledbyon icon buttons. - Detect invalid ARIA attribute combinations.
- Flag redundant ARIA on semantic elements.
- Identify missing
-
Focus Management Check
- Verify modals trap focus and restore on close.
- Check that dynamic content updates announce via
aria-liveif needed.
-
Contrast and Motion Check
- Flag hardcoded colors that may violate contrast ratios (suggest calculation).
- Detect animations without
prefers-reduced-motionsupport.
Step 5: Categorize Violations
Assign severity:
- Critical: Component is unusable via keyboard or screen reader.
- Serious: Missing required ARIA or semantic structure.
- Moderate: Suboptimal patterns that hinder usability.
- Minor: Best practice improvements.
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-react is a skill published in the GitHub repository vanessamarely/ai-playbook-reposito (2 stars, last pushed 1mo ago), licensed MIT. It adds 48 tokens to every session and 1,958 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.
