Validate uncommitted changes in this skills repo before committing. Use when the user invokes /check-local-changes, asks to check, review, or validate local/uncommitted/pending changes, or before committing a new or modified skill.
Execute a remote agent skill from a skills.sh or GitHub URL without installing it on the system. Use when the user invokes /run-skill <url>, shares a skills.sh link, points to a SKILL.md on GitHub, or asks to run/try/test a skill one-off without adding it to their machine.

metascraper extracts normalized metadata from the input HTML you provide, using ordered rule bundles.
Extraction quality depends on the accuracy of that input HTML.
Install only what you need:
npm install metascraper \
metascraper-author \
metascraper-date \
metascraper-description \
metascraper-image \
metascraper-logo \
metascraper-publisher \
metascraper-title \
metascraper-url
Minimal extraction:
const metascraper = require('metascraper')([
require('metascraper-author')(),
require('metascraper-date')(),
require('metascraper-description')(),
require('metascraper-image')(),
require('metascraper-logo')(),
require('metascraper-publisher')(),
require('metascraper-title')(),
require('metascraper-url')()
])
const metadata = await metascraper({
url: 'https://example.com/article',
html: '<html>...</html>'
})
metascraper({ url, html }).pickPropNames when speed matters.metascraper needs both url and html.
html-get).For accurate rendered markup, use the local html-get skill before running metascraper.
Create an instance:
const metascraper = require('metascraper')([/* rule bundles */])
Run extraction:
const metadata = await metascraper({
url,
html,
htmlDom, // optional pre-parsed DOM
rules, // optional extra rules at runtime
pickPropNames, // optional Set of fields to compute
omitPropNames, // optional Set of fields to skip
validateUrl // default true
})
Compute only selected fields:
const metadata = await metascraper({
url,
html,
pickPropNames: new Set(['title', 'description', 'image'])
})
Skip expensive or unwanted fields:
const metadata = await metascraper({
url,
html,
omitPropNames: new Set(['logo'])
})
When both are present, pickPropNames takes precedence.
Example with bundle options:
const metascraper = require('metascraper')([
require('metascraper-logo')({
filter: imageUrl => imageUrl.endsWith('.png')
})
])
