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 | $0.00041 | $0.00909 |
| Opus 5 | $0.00020 | $0.00454 |
| Sonnet 5 | $0.00008 | $0.00182 |
| Haiku 4.5 | $0.00004 | $0.00091 |
Grade A, and why
puppeteer 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.

Usage Examples
Generate PDF from HTML
import puppeteer from 'puppeteer';
async function generatePDF(html: string, outputPath: string) {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.setContent(html, { waitUntil: 'networkidle0' });
await page.pdf({
path: outputPath,
format: 'A4',
margin: { top: '20mm', right: '20mm', bottom: '20mm', left: '20mm' },
printBackground: true,
});
await browser.close();
}
// Usage
const html = `
<html>
<head><style>body { font-family: Arial; }</style></head>
<body><h1>Invoice #001</h1><p>Total: $100.00</p></body>
</html>
`;
await generatePDF(html, 'invoice.pdf');
Take Screenshot
async function takeScreenshot(url: string, outputPath: string) {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.setViewport({ width: 1920, height: 1080 });
await page.goto(url, { waitUntil: 'networkidle2' });
await page.screenshot({
path: outputPath,
fullPage: true,
type: 'png',
});
await browser.close();
}
Web Scraping
async function scrapeData(url: string) {
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto(url, { waitUntil: 'domcontentloaded' });
const data = await page.evaluate(() => {
const items = document.querySelectorAll('.product');
return Array.from(items).map(item => ({
title: item.querySelector('h2')?.textContent?.trim(),
price: item.querySelector('.price')?.textContent?.trim(),
}));
});
await browser.close();
return data;
}
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.
- 9d ago First seen · 150 lines · 41 tokens per session scan A 056c91150dc9
puppeteer is a skill published in the GitHub repository AIDotNet/MoYuCode (85 stars, last pushed 7mo ago), licensed MIT. It adds 41 tokens to every session and 909 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.
