Stealth Agent Browser
Gives Claude a stealth Chromium browser that passes modern bot detection (CreepJS, Sannysoft) using rebrowser-playwright's patched CDP runtime. Returns Playwright aria snapshots as compact YAML with ref IDs instead of raw HTML, cutting token costs by 20x. Supports hybrid mode with Set-of-Mark numbered overlays so vision models can ground elements visually. Ships with Mozilla Readability extraction, residential proxy rotation with sticky session templates, Bezier-curve mouse movements, and CapSolver/2Captcha fallback. Useful when you need to automate interactions on protected sites you own or have permission to test, with a fingerprint that matches real Chrome at the TLS and DOM layers.
