Browser Automation with agent-browser
Quick start
agent-browser open <url> # Navigate to page
agent-browser snapshot -i # Get interactive elements with refs
agent-browser click @e1 # Click element by ref
agent-browser fill @e2 "text" # Fill input by ref
agent-browser close # Close browser
Core workflow
- Navigate:
agent-browser open <url>
- Snapshot:
agent-browser snapshot -i (returns elements with refs like @e1, @e2)
- Interact using refs from the snapshot
- Re-snapshot after navigation or significant DOM changes
