Aegis: AI-Powered Browser Automation Agent

Project Overview

Aegis is an autonomous web browsing agent that replaces traditional, fragile DOM scraping with Chromium’s native Accessibility Tree (AXTree) for robust semantic web interaction.

Architecture & Key Features

  • Semantic Perception Engine: Utilizes Python, Playwright, and pydantic-ai to parse the accessibility tree directly, providing clear structural signals to LLMs while resisting UI updates.
  • Token Optimization Pipeline: Features an automated pipeline that dynamically collapses repetitive and non-essential DOM nodes, preventing context window exhaustion during complex multi-step browser workflows.
