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 | $0.00042 | $0.00319 |
| Opus 5 | $0.00021 | $0.00160 |
| Sonnet 5 | $0.00008 | $0.00064 |
| Haiku 4.5 | $0.00004 | $0.00032 |
Grade A, and why
frontend-ui-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 9d 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.
What it actually says
Frontend UI and accessibility
Defaults
- Semantic HTML first; ARIA only when native semantics insufficient
- Keyboard-operable for every interactive control
- Visible focus states; do not remove outlines without replacement
- Color contrast and non-color-only status cues
Build checklist
- Heading hierarchy (
h1once per view where applicable) - Labels tied to inputs (
label/fororaria-labelledby) - Buttons vs links used correctly
- Modals: focus trap,
Escape, return focus on close - Images: meaningful
altor decorativealt="" - Dynamic updates:
aria-livewhen needed
Review checklist
- Tab order logical; no keyboard traps
- Touch targets adequate on mobile
- Motion respects
prefers-reduced-motion - Forms: errors associated with fields
Performance interaction
Avoid layout thrash; lazy-load below fold; measure LCP/CLS when shipping UI.

What ships with it
1 file 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.
