Triggered when user asks to add structured logging, set up error tracking, implement monitoring, or configure observability. Automatically delegates to the logging-specialist agent.
Triggered when user asks to implement data validation, create validation schemas, add input validation, or ensure type-safe validation. Automatically delegates to the validation-specialist agent.
Triggered when user asks to design architecture, plan system structure, or make architectural decisions. Automatically delegates to the architect agent.
Triggered when user asks to audit code quality, assess maintainability, or review overall code quality. Automatically delegates to the quality-auditor agent.
Triggered when user asks to design APIs, create API specifications, or plan API endpoints. Automatically delegates to the api-designer agent.
Triggered when user asks to design database schemas, plan data models, or optimize database structure. Automatically delegates to the database-designer agent.

Use this skill when helping users extract metadata from webpages, build link previews, create SEO tools, parse OpenGraph/Twitter Card data, or run social metadata validation audits.
import { extract } from "ogie";
const result = await extract("https://github.com");
if (result.success) {
console.log(result.data.og.title);
console.log(result.data.og.description);
console.log(result.data.og.images[0]?.url);
}
extract(url, options?)Fetch and extract metadata from a URL.
import { extract } from "ogie";
const result = await extract("https://example.com", {
timeout: 10000,
maxRedirects: 5,
userAgent: "MyBot/1.0",
fetchOEmbed: true,
convertCharset: true,
});
if (result.success) {
console.log(result.data.og.title);
console.log(result.data.twitter.card);
console.log(result.data.basic.favicon);
}
extractFromHtml(html, options?)Extract metadata from an HTML string without network requests.
import { extractFromHtml } from "ogie";
const html = `
<html>
<head>
<meta property="og:title" content="My Page">
<meta property="og:image" content="/images/hero.jpg">
</head>
</html>
`;
const result = extractFromHtml(html, {
baseUrl: "https://example.com", // Required for relative URLs
});
extractWithDiagnostics(url, options?)Fetch metadata and return social diagnostics (valid, invalid, missing, warnings).
import { extractWithDiagnostics } from "ogie";
const result = await extractWithDiagnostics("https://example.com", {
mode: "platform-valid",
});
if (result.success) {
console.log(result.data.og.title);
console.log(result.diagnostics.summary);
}
extractFromHtmlWithDiagnostics(html, options?)Parse HTML and return metadata with social diagnostics.
import { extractFromHtmlWithDiagnostics } from "ogie";
const result = extractFromHtmlWithDiagnostics(html, {
baseUrl: "https://example.com",
mode: "platform-valid",
});
extractBulk(urls, options?)Extract metadata from multiple URLs with rate limiting.
import { extractBulk } from "ogie";
const result = await extractBulk(
["https://github.com", "https://twitter.com", "https://youtube.com"],
{
concurrency: 10,
concurrencyPerDomain: 3,
minDelayPerDomain: 200,
onProgress: (p) => console.log(`${p.completed}/${p.total}`),
}
);
for (const item of result.results) {
if (item.result.success) {
console.log(`${item.url}: ${item.result.data.og.title}`);
}
}
createCache(options?)Create an LRU cache for extraction results.
import { extract, createCache } from "ogie";
const cache = createCache({
maxSize: 100,
ttl: 300_000, // 5 minutes
});
// First call fetches, second returns cached
await extract("https://github.com", { cache });
await extract("https://github.com", { cache }); // Instant

Ogie includes built-in protections:
// Allow private URLs for local development
await extract("http://localhost:3000", {
allowPrivateUrls: true,
});
