Hiroshi features a modular headless browser controller that allows agents to programmatically navigate websites, capture DOM elements, and extract text data.

​
🍪 1. Sandbox Cookie & Session Isolation

To prevent cross-domain state leaks and protect operator identities:
  • Every browser session initializes an independent user data directory containing fully isolated cookie jars and local storage databases.
  • Ephemeral profiles are automatically purged on agent run shutdown.

​
🌐 2. CDP Socket Integration

The browser engine communicates with the underlying Chromium subprocess over local websocket loops using the Chrome DevTools Protocol (CDP).
  • Remote debugging sockets are restricted to local interface bindings (127.0.0.1) to prevent external exposure.
