Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00067 | $0.02037 |
| Opus 5 | $0.00034 | $0.01019 |
| Sonnet 5 | $0.00013 | $0.00407 |
| Haiku 4.5 | $0.00007 | $0.00204 |
Grade A, and why
wcag-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 13d 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
WCAG Accessibility (EN 301 549 / European Standard)
The Standard
The European Accessibility Act (EAA) requires digital products and services in the EU to meet EN 301 549, which references WCAG 2.2 Level AA as the technical baseline. This is not optional — it is a legal requirement for products operating in the EU market.
Default: always build to WCAG 2.2 AA. Deviating requires explicit, documented justification. Do not skip accessibility requirements because of timeline pressure or design preference.
WCAG 2.2 AA organises requirements under four principles: Perceivable, Operable, Understandable, Robust.
Perceivable
Users must be able to perceive all content and UI components.
Colour Contrast
| Context | Minimum ratio | Enhanced (AAA) |
|---|---|---|
| Normal text (< 18pt / < 14pt bold) | 4.5 : 1 | 7 : 1 |
| Large text (≥ 18pt / ≥ 14pt bold) | 3 : 1 | 4.5 : 1 |
| UI components and graphical objects | 3 : 1 | — |
Check contrast on the real rendered page, not the spec (dembrandt engine, optional). Design-time swatches lie once real text lands on real backgrounds, gradients, and overlays.
get_findings/render_reportrun against the live DOM and surface the actual failing text/background pairs with their measured ratios — a fast way to catch the combinations a static palette review misses. Seeextract-design.
Disabled elements are exempt. WCAG explicitly excludes inactive UI components from contrast requirements (WCAG 1.4.3 exception). A disabled button may use low-contrast text — this is intentional and correct, as it communicates the unavailable state.
Do not use colour as the only means of conveying information (e.g. a red border alone to indicate an error — add an icon or text label).
Text Alternatives
- Every meaningful image needs
alttext describing its content or function - Decorative images use
alt=""so screen readers skip them - Icons used as buttons need an accessible label:
aria-labelor visually hidden text - Charts and data visualisations need a text summary or data table alternative
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-accessibility is a skill published in the GitHub repository dembrandt/dembrandt-skills (54 stars, last pushed 2d ago), licensed MIT. It adds 67 tokens to every session and 2,037 once invoked, about $0.0003 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.
