Browser automation via agent-browser CLI. Use when the user needs to navigate websites, fill forms, click buttons, take screenshots, extract data, or test web apps.
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.

agent-browser fill @e1 "[email protected]"

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
# 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
# Wait
agent-browser wait @e1 # Wait for element

# ... login once, all future runs are authenticated
# Option 3: Session name (auto-save/restore)
agent-browser --session-name myapp open https://app.example.com/login

agent-browser --session s1 open https://site-a.com
agent-browser --session s2 open https://site-b.com
agent-browser session list
agent-browser eval 'document.title'
# Complex JS — use --stdin to avoid shell quoting issues
agent-browser eval --stdin <<'EVALEOF'
JSON.stringify(Array.from(document.querySelectorAll("a")).map(a => a.href))
EVALEOF
Always close sessions when done:
agent-browser close
agent-browser --session s1 close
