Computer Use & Browser Control

🔧 Tool Use & Function Calling⏱ 10 min⭐ 80 BASE XP⌨ HANDS-ON LAB

Desktop Automation

Modern frontier models (like Claude Sonnet 5.5 / Opus 5.5, GPT-6 Astra, and Gemini 4 Argon / 3.8 Flash) have native Computer Use and browser-control capabilities. They can observe screenshots, calculate pixel coordinates, and issue desktop actions.

Action: computer_use
Command: { "action": "mouse_move", "coordinate": [550, 200] }
Action: computer_use
Command: { "action": "left_click" }

Sandboxing Requirements

Computer interactions carry severe risks (deleting files, sending emails, executing malware). Absolute Rules for Computer Use:

  • Always execute in isolated Docker containers or throwaway VMs.
  • Never run as root.
  • Use a separate sub-agent with limited permissions if possible.

⭐ +150 XP

Your agent needs eyes and hands on the web. Install Playwright's browser engine, record actions with codegen, and capture a page screenshot - the exact toolkit browser agents are built on.

1Install the Chromium browser engine that Playwright automations drive.
2Launch codegen - it records your clicks and typing as replayable automation code.
3Give your agent vision: capture a full-page screenshot from the CLI.
