This skill covers everything a plain fetch cannot finish: a page that renders in JavaScript, a click or a form, a screenshot, a login that must persist across pages, or a host that blocks generic fetchers with a WAF or a 403. A mandatory routing phase picks the cheapest tier first and climbs only when it cannot do the job: Tier 1 is headless extraction with WAF bypass, Tier 1.5 reaches for platform-native APIs, especially on Chinese platforms, and Tier 2 opens a real browser, either an owned stealth-mode engine the code launches or the user's own already signed-in browser.
Tier 1, called insane-search, is roughly ten times faster than spinning up a browser and handles most blocked-page requests through curl_cffi TLS impersonation, yt-dlp across more than a thousand sites, official public APIs, mobile URL transforms, provenance-tagged Wayback and archive.today snapshots, a key-gated Jina Reader, and a Playwright real-Chrome fallback, with the engine living inside the skill as a Python module invoked with a target URL and options such as a CSS selector for positive-proof validation or a device type. A result pulled from an archive snapshot is explicitly a dated copy and must be reported with its snapshot timestamp, never presented as the live page.
The skill ships its own engine code, including fetch-chain, referer and surrogate-archive modules plus Playwright templates for desktop and mobile Chrome, and an ATTRIBUTION.md file, with a reference file for each tier to read before acting.
