Agent Browser

CLI browser automation via Chrome/Chromium CDP. Install: npm i -g agent-browser && agent-browser install.

Before using this skill, verify the tool is available by running which agent-browser. If the command is not found, tell the user that browser automation requires the agent-browser CLI and Chromium, which are only available in the heavy container image. Do not attempt to install it at runtime.

Core Workflow

1. agent-browser open <url>, navigate
2. agent-browser snapshot -i, get interactive elements with refs (@e1, @e2, ...)
3. Interact using refs, click @e1, fill @e2 "text"
4. Re-snapshot after any navigation or DOM change, refs are invalidated

agent-browser open https://example.com/form
agent-browser snapshot -i
# @e1 [input] "Email", @e2 [input] "Password", @e3 [button] "Submit"
agent-browser fill @e1 "user@example.com"
agent-browser fill @e2 "secret"
agent-browser click @e3
agent-browser wait --load networkidle
agent-browser snapshot -i

Chain commands with && when you don't need intermediate output:

agent-browser open https://example.com && agent-browser wait --load networkidle && agent-browser snapshot -i

Commands

# Navigation
agent-browser open <url>
agent-browser close

# Snapshot
agent-browser snapshot -i                # Interactive elements with refs
agent-browser snapshot -s "#selector"    # Scope to CSS selector

# Interaction (use @refs from snapshot)
agent-browser click @e1
agent-browser fill @e2 "text"            # Clear + type
agent-browser type @e2 "text"            # Type without clearing
agent-browser select @e1 "option"
agent-browser check @e1
agent-browser press Enter
agent-browser scroll down 500

# Get info
agent-browser get text @e1
agent-browser get url
agent-browser get title
