--- name: agent-browser description: Browser automation command reference and usage patterns for web testing, form filling, screenshots, and data extraction. user-invocable: false --- # Browser Automation with agent-browser ## Quick start ```bash agent-browser open # 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 1. Navigate: `agent-browser open ` 2. Snapshot: `agent-browser snapshot -i` (returns elements with refs like `@e1`, `@e2`) 3. Interact using refs from the snapshot 4. Re-snapshot after navigation or significant DOM changes ## Commands ### Navigation ```bash agent-browser open # Navigate to URL (aliases: goto, navigate) # Supports: https://, http://, file://, about:, data:// # Auto-prepends https:// if no protocol given agent-browser back # Go back agent-browser forward # Go forward agent-browser reload # Reload page agent-browser close # Close browser (aliases: quit, exit) agent-browser connect 9222 # Connect to browser via CDP port ``` ### Snapshot (page analysis) ```bash agent-browser snapshot # Full accessibility tree agent-browser snapshot -i # Interactive elements only (recommended) agent-browser snapshot -c # Compact output agent-browser snapshot -d 3 # Limit depth to 3 agent-browser snapshot -s "#main" # Scope to CSS selector ``` ### Interactions (use @refs from snapshot) ```bash agent-browser click @e1 # Click agent-browser dblclick @e1 # Double-click agent-browser focus @e1 # Focus element agent-browser fill @e2 "text" # Clear and type agent-browser type @e2 "text" # Type without clearing agent-browser press Enter # Press key (alias: key) agent-browser press Control+a # Key combination agent-browser keydown Shift # Hold key down agent-browser keyup Shift # Release key agent-browser hover @e1 # Hover agent-browser check @e1 # Check checkbox agent-browser uncheck @e1 # Uncheck checkbox agent-browser select @e1 "value" # Select dropdown option agent-browser select @e1 "a" "b" # Select multiple options agent-browser scroll down 500 # Scroll page (default: down 300px) agent-browser scrollintoview @e1 # Scroll element into view (alias: scrollinto) agent-browser drag @e1 @e2 # Drag and drop agent-browser upload @e1 file.pdf # Upload files ``` ### Get information ```bash agent-browser get text @e1 # Get element text agent-browser get html @e1 # Get innerHTML agent-browser get value @e1 # Get input value agent-browser get attr @e1 href # Get attribute agent-browser get title # Get page title agent-browser get url # Get current URL agent-browser get count ".item" # Count matching elements agent-browser get box @e1 # Get bounding box agent-browser get styles @e1 # Get computed styles (font, color, bg, etc.) ``` ### Check state ```bash agent-browser is visible @e1 # Check if visible agent-browser is enabled @e1 # Check if enabled agent-browser is checked @e1 # Check if checked ``` ### Screenshots & PDF ```bash agent-browser screenshot # Screenshot to stdout agent-browser screenshot path.png # Save to file agent-browser screenshot --full # Full page agent-browser pdf output.pdf # Save as PDF ``` ### Video recording ```bash agent-browser record start ./demo.webm # Start recording (uses current URL + state) agent-browser click @e1 # Perform actions agent-browser record stop # Stop and save video agent-browser record restart ./take2.webm # Stop current + start new recording ``` Recording creates a fresh context but preserves cookies/storage from your session. If no URL is provided, it automatically returns to your current page. For smooth demos, explore first, then start recording. ### Wait ```bash agent-browser wait @e1 # Wait for element agent-browser wait 2000 # Wait milliseconds agent-browser wait --text "Success" # Wait for text (or -t) agent-browser wait --url "**/dashboard" # Wait for URL pattern (or -u) agent-browser wait --load networkidle # Wait for network idle (or -l) agent-browser wait --fn "window.ready" # Wait for JS condition (or -f) ``` ### Mouse control ```bash agent-browser mouse move 100 200 # Move mouse agent-browser mouse down left # Press button agent-browser mouse up left # Release button agent-browser mouse wheel 100 # Scroll wheel ``` ### Semantic locators (alternative to refs) ```bash agent-browser find role button click --name "Submit" agent-browser find text "Sign In" click agent-browser find text "Sign In" click --exact # Exact match only agent-browser find label "Email" fill "user@test.com" agent-browser find placeholder "Search" type "query" agent-browser find alt "Logo" click agent-browser find title "Close" click agent-browser find testid "submit-btn" click agent-browser find first ".item" click agent-browser find last ".item" click agent-browser find nth 2 "a" hover ``` ### Browser settings ```bash agent-browser set viewport 1920 1080 # Set viewport size agent-browser set device "iPhone 14" # Emulate device agent-browser set geo 37.7749 -122.4194 # Set geolocation (alias: geolocation) agent-browser set offline on # Toggle offline mode agent-browser set headers '{"X-Key":"v"}' # Extra HTTP headers agent-browser set credentials user pass # HTTP basic auth (alias: auth) agent-browser set media dark # Emulate color scheme agent-browser set media light reduced-motion # Light mode + reduced motion ``` ### Cookies & Storage ```bash agent-browser cookies # Get all cookies agent-browser cookies set name value # Set cookie agent-browser cookies clear # Clear cookies agent-browser storage local # Get all localStorage agent-browser storage local key # Get specific key agent-browser storage local set k v # Set value agent-browser storage local clear # Clear all ``` ### Network ```bash agent-browser network route # Intercept requests agent-browser network route --abort # Block requests agent-browser network route --body '{}' # Mock response agent-browser network unroute [url] # Remove routes agent-browser network requests # View tracked requests agent-browser network requests --filter api # Filter requests ``` ### Tabs & Windows ```bash agent-browser tab # List tabs agent-browser tab new [url] # New tab agent-browser tab 2 # Switch to tab by index agent-browser tab close # Close current tab agent-browser tab close 2 # Close tab by index agent-browser window new # New window ``` ### Frames ```bash agent-browser frame "#iframe" # Switch to iframe agent-browser frame main # Back to main frame ``` ### Dialogs ```bash agent-browser dialog accept [text] # Accept dialog agent-browser dialog dismiss # Dismiss dialog ``` ### JavaScript ```bash agent-browser eval "document.title" # Run JavaScript ``` ## Global options ```bash agent-browser --session ... # Isolated browser session agent-browser --json ... # JSON output for parsing agent-browser --headed ... # Show browser window (not headless) agent-browser --full ... # Full page screenshot (-f) agent-browser --cdp ... # Connect via Chrome DevTools Protocol agent-browser -p ... # Cloud browser provider (--provider) agent-browser --proxy ... # Use proxy server agent-browser --headers ... # HTTP headers scoped to URL's origin agent-browser --executable-path
