AIagentsbrowser securityprompt injectionPixieBrixOpenClaw There are 6 billion internet users. With AI agents, we're quickly heading to 60 to 600 billion "users" of the web. How do we keep all those agents safe when they touch the browser? At PixieBrix, we've spent years protecting BPO contact centers from insider risk, fraud, and social engineering in the browser. Today, we're applying that defense to AI agents and making a free, source-available, browser extension available (on GitHub and ClawHub). Your AI agent that lands on a fresh page is one prompt injection away from leaking credentials, one dark pattern away from buying the wrong thing, and one fake review away from a bad recommendation. Agent Browser Shield sits between the browser and the agent. It blocks: - Prompt injection: visible or hidden instructions in page content - Dark patterns: manipulative UI designed to trick/coerce - Context pollution: low-value context that impairs instruction following A useful side effect: stripping irrelevant content also cuts token burn. Come join us on our mission. File issues, send PRs, or just tell me what you hate/love! The threat surface for agentic browsing is evolving fast. Let's defend our AI assistants together! - ⭐ Star the GitHub repo: - 🦞 Star the OpenClaw skill: ![Side-by-side demo: an unprotected agent vs. one shielded by agent-browser-shield](https://toddschiller.com/assets/images/agent-browser-shield-alpha/demo.webp) More on - [`#AI`](https://toddschiller.com/tag/ai.html) (12) - [`#agents`](https://toddschiller.com/tag/agents.html) (5) - [`#browser security`](https://toddschiller.com/tag/browser-security.html) (3) - [`#prompt injection`](https://toddschiller.com/tag/prompt-injection.html) (3) - [`#PixieBrix`](https://toddschiller.com/tag/pixiebrix.html) (11) - [`#OpenClaw`](https://toddschiller.com/tag/openclaw.html)
