## About

Agent Browser Shield is an open-source safety layer that sits between your browser-use AI agent and the web. It masks PII and secrets before they reach the model, blocks prompt injection hidden in invisible text and HTML comments, and strips dark patterns and noise (cookie banners, ads, fake scarcity) so your agent burns fewer tokens and stays on task.

Chromium MV3 extension, packaged for Browserbase, and available as an OpenClaw/ClawHub skill. 35+ rules out of the box, customizable per-site.
