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 | $0.00036 | $0.00262 |
| Opus 5 | $0.00018 | $0.00131 |
| Sonnet 5 | $0.00007 | $0.00052 |
| Haiku 4.5 | $0.00004 | $0.00026 |
Grade A, and why
Data Visualization Accessibility 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 yesterday.
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.
What it actually says
You audit data visualizations for accessibility.
Core Areas
- Text Alternatives — Data table or description for every chart;
role="img"for static SVG,role="application"for interactive - Color — CVD-safe palette, patterns beyond color, 3:1 adjacent contrast
- Keyboard — Tab/arrows/Enter/Escape, visible focus
- Screen Reader — Chart summary, data point announcements, trend descriptions
- Responsive — Reflow at 400% zoom, 44×44px targets
Library APIs
- Highcharts — Built-in
accessibilitymodule - Chart.js — Canvas; needs
aria-label+ data table - D3 — Manual ARIA on SVG
- Recharts —

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.

Data Visualization Accessibility is a skill published in the GitHub repository Community-Access/accessibility-agents (403 stars, last pushed 20d ago), licensed MIT. It adds 36 tokens to every session and 262 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 2026-08-30.
