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 | $0.00054 | $0.00326 |
| Opus 5 | $0.00027 | $0.00163 |
| Sonnet 5 | $0.00011 | $0.00065 |
| Haiku 4.5 | $0.00005 | $0.00033 |
Grade A, and why
shadcn_ui-sonner 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 10d 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
Shadcn UI — Sonner
Instructions
Sonner is an opinionated toast component. Ensure ShadSonner is in the widget tree (e.g. in app builder). Get the controller with ShadSonner.of(context). Call sonner.show(ShadToast(...)) to show a toast; use sonner.hide(id) to dismiss. Each toast can have id, title, description, and optional action (e.g. an Undo button).
Show toast
ShadButton.outline(
child: const Text('Show Toast'),
onPressed: () {
final sonner = ShadSonner.of(context);
final id = Random().nextInt(1000);
final now = DateTime.now();
sonner.show(
ShadToast(
id: id,
title: const Text('Event has been created'),
description: Text(DateFormat.yMd().add_jms().format(now)),
action: ShadButton(
child: const Text('Undo'),
onPressed: () => sonner.hide(id),
),
),
);
},
)
Use a unique id per toast so you can hide it from the action button or elsewhere.
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.

shadcn_ui-sonner is a skill published in the GitHub repository serverpod/skills-registry (9 stars, last pushed 6mo ago), licensed BSD-3-Clause. It adds 54 tokens to every session and 326 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
