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 | $0.00141 | $0.02005 |
| Opus 5 | $0.00071 | $0.01002 |
| Sonnet 5 | $0.00028 | $0.00401 |
| Haiku 4.5 | $0.00014 | $0.00200 |
Grade A, and why
better-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 4d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Accessibility that comes with the craft
Accessibility is not a compliance checkbox bolted on at the end; it is the floor for interface craft. Most of it is free if you use the platform: native elements ship with keyboard support, real labels announce themselves, and a visible focus ring is one CSS rule. Apply these principles when building or reviewing UI code, and write every fix in the project's own idiom: the styling system already in use, never a second one alongside it.
When reviewing, walk the interface as a keyboard-only user first (every flow must complete without a mouse), then as a screen-reader user: does each control announce a name, a role, and its state? When unsure, prefer the platform default over a custom rebuild, and remove ARIA rather than add it.
Rendered-pair contrast measurement and color remediation are covered by the better-colors skill; visual text sizing and iOS input zoom by better-typography; spatial RTL layout by better-layout.
Quick Reference
| Category | When to Use |
|---|---|
| Focus & Keyboard | Focus rings, skip links, tabindex, focus trapping, APG keyboard patterns |
| Semantics & ARIA | Native elements first, button vs link, landmarks, accessible names, disabled states |
| Forms | Labels, autocomplete, error messaging, input types |
| Screen Readers | Visually hidden content, live regions, toasts, alt text, SVG |
| Hit Areas | Target sizes, expanding hit areas, collision rules |
| Motion & Zoom | prefers-reduced-motion, autoplay and timed UI, 200% zoom, reflow, rem vs px |
| Review Output Format | Severity scale, findings table, verification, verdict |
Core Principles
1. Native Elements First
The first rule of ARIA: don't use ARIA when a native element exists. <button> for actions, <a href> for navigation (it must support Cmd/Ctrl/middle-click), never <div onClick>. No ARIA is better than bad ARIA.
What ships with it
8 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.

better-accessibility is a skill published in the GitHub repository talebook/talebook (5,732 stars, last pushed today), licensed BSD-2-Clause. It adds 141 tokens to every session and 2,005 once invoked, about $0.0007 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.
