Use this skill for testing PDF upload dialogs, form interactions, dropdown selections, and visual verification of web pages. version: 1.0.0 --- # Agent Browser Skill Automate browser interactions for UI testing, debugging, and development iteration using Claude Code's agent-browser automation tool. ## Overview This skill enables interactive browser automation directly from Claude Code, allowing you to: - Launch browsers and navigate to URLs - Inspect and interact with page elements - Verify UI state and extract information - Test workflows like form submissions and file uploads - Take screenshots for visual verification ## When This Skill Applies This skill activates when you need to: - **Test UI components** - Verify buttons, forms, dropdowns work correctly - **Inspect page structure** - Examine DOM elements and their properties - **Automate workflows** - Click, fill, and submit forms programmatically - **Upload files** - Test file inputs and upload flows - **Verify visual state** - Take screenshots at different stages - **Debug page issues** - Check element visibility, attributes, content ## Agent-Browser CLI Reference ``` agent-browser - fast browser automation CLI for AI agents Usage: agent-browser [args] [options] Core Commands: open Navigate to URL click Click element (or @ref) dblclick Double-click element type Type into element fill Clear and fill press Press key (Enter, Tab, Control+a) hover Hover element focus Focus element check Check checkbox uncheck Uncheck checkbox select Select dropdown option drag Drag and drop upload Upload files scroll [px] Scroll (up/down/left/right) scrollintoview Scroll element into view wait Wait for element or time screenshot [path] Take screenshot pdf Save as PDF snapshot Accessibility tree with refs (for AI) eval Run JavaScript connect Connect to browser via CDP close Close browser Navigation: back Go back forward Go forward reload Reload page Get Info: agent-browser get [selector] text, html, value, attr , title, url, count, box, styles Check State: agent-browser is visible, enabled, checked Find Elements: agent-browser find [text] role, text, label, placeholder, alt, title, testid, first, last, nth Mouse: agent-browser mouse [args] move , down [btn], up [btn], wheel [dx] Browser Settings: agent-browser set [value] viewport , device , geo offline [on|off], headers , credentials media [dark|light] [reduced-motion] Network: agent-browser network route [--abort|--body ] unroute [url] requests [--clear] [--filter ] Storage: cookies [get|set|clear] Manage cookies storage Manage web storage Tabs: tab [new|list|close|] Manage tabs Debug: trace start|stop [path] Record trace record start [url] Start video recording record stop Stop and save video console [--clear] View console logs errors [--clear] View page errors highlight Highlight element Sessions: session Show current session name session list List active sessions Snapshot Options: -i, --interactive Only interactive elements -c, --compact Remove empty structural elements -d, --depth Limit tree depth -s, --selector Scope to CSS selector Options: --session Isolated session --headers HTTP headers for auth --executable-path Custom browser executable --json JSON output --full, -f Full page screenshot --headed Show browser window --debug Debug output Examples: agent-browser open example.com agent-browser snapshot -i # Interactive elements agent-browser click @e2 # Click by ref agent-browser fill @e3 "test@example.com" agent-browser screenshot --full ``` ## Quick Examples **Open a page and take screenshot:** ```bash agent-browser open http://localhost:3000/instructions agent-browser screenshot ``` **Click an element:** ```bash agent-browser click "button[data-testid='submit']" ``` **Fill an input field:** ```bash agent-browser fill "input[name='email']" "user@example.com" ``` **Select from dropdown:** ```bash agent-browser select "select[name='biller']" "XPO Logistics" ``` **Take a snapshot (for AI):** ```bash agent-browser snapshot --interactive ``` **Wait for element:** ```bash agent-browser wait "div.success-message" ``` **Upload a file:** ```bash agent-browser upload "input[type='file']" "~/Downloads/invoice.pdf" ``` ## Real Use Cases from Development ### 1. **Testing 3PL Selector in PDF Upload Dialog** When developing the 3PL instructions feature for PDF invoice extraction, agent-browser verified that: - The dropdown selector appears with correct label: "3PL / Biller (Optional)" - All billers from instruction sets populate in dropdown options - Selection state persists when uploading files - Selected biller name is passed to the extraction API **Why it mattered:** Confirmed frontend integration with backend instructions data without manual browser testing. ### 2. **Verifying Page Navigation and Loading** Used to test that specific routes load correctly: - http://localhost:3000/instructions - Instructions management page - http://localhost:3000/summary-charges/add-charges?brand=TCT - PDF upload dialog **Why it mattered:** Quick verification that pages are accessible and rendering, catching routing errors early. ### 3. **Capturing Screenshots for Documentation** Took snapshots at each test phase to document: - Initial page state before interactions - Dialog open with selector visible - Form filled with test data - Success states after submission **Why it mattered:** Visual evidence that UI changes work as expected, useful for PRs and bug reports. ### 4. **Inspecting Element Structure** Used `snapshot` command to: - Verify SearchableSelect component rendered with correct props - Check HTML hierarchy of dialogs and form elements - Understand page layout before interacting **Why it mattered:** Understanding page structure before writing selectors for clicks/fills. ### 5. **Testing Form Workflows** Tested complete user journeys: - Click "Import from PDF" button - Select instruction set from dropdown - Upload PDF file through file input - Trigger extraction - Wait for success toast **Why it mattered:** Caught form submission issues, timing problems, and missing UI elements. ## Common Workflows ### Testing a PDF Upload Dialog ```bash # 1. Navigate to the page /browser open http://localhost:3000/summary-charges/add-charges?brand=TCT # 2. Click "Import from PDF" button /browser click "button:has-text('Import from PDF')" # 3. Select instruction set from dropdown /browser select "select.instruction-select" "Standard Warehouse Format" # 4. Upload PDF file /browser upload "input[type='file']" "~/Downloads/misen.pdf" # 5. Click extract button /browser click "button:has-text('Extract Charges')" # 6. Wait for completion and verify /browser wait ".success-toast" --timeout 30000 /browser screenshot /browser inspect "table[data-testid='extracted-charges']" ``` ### Testing Instructions Management ```bash # Navigate to instructions page /browser open http://localhost:3000/instructions # Click "New Instruction Set" /browser click "button:has-text('New Instruction Set')" # Fill form fields /browser fill "input[name='name']" "Test Warehouse Format" /browser fill "textarea[name='instructions']" "## Invoice Structure\n- Invoice number: Top-right" # Add biller tag /browser click "button:has-text('Add Biller')" /browser fill ".tag-input" "XPO Logistics" /browser click "button:has-text('Add Tag')" # Submit form /browser click "button[type='submit']" # Verify success /browser wait ".success-toast" /browser screenshot ``` ### Debugging Page State ```bash # Open page with issues /browser open http://localhost:3000/summary-charges # Inspect critical elements /browser inspect "dialog" /browser inspect "select" /browser inspect "button[type='submit']" # Take screenshots /browser screenshot # Verify form state /browser inspect "form[data-testid='pdf-upload-form']" ``` ## Element Selectors The skill supports multiple selector formats: - **CSS selectors**: `button.primary`, `input[data-testid='email']` - **Text matching**: `button:has-text('Submit')`, `div:has-text('Error')` - **Data attributes**: `[data-testid='submit']`, `[data-id='123']` - **XPath** (when needed): Complex element queries ## Command Details ### navigate Move to a new URL in the current session ```bash /browser navigate http://localhost:3000/new-page ``` ### click Click an element and capture the result ```bash /browser click ".submit-button" ``` ### fill Enter text into an input field ```bash /browser fill "input[name='username']" "testuser" /browser fill ".search-box" "query text" ``` ### select Choose an option from a dropdown ```bash /browser select "select[name='option']" "Option Value" ``` ### wait Poll for element appearance with optional timeout (default 5000ms) ```bash /browser wait ".modal-content" --timeout 10000 ``` ### inspect Extract element structure and content information ```bash /browser inspect ".data-table" ``` ### upload Submit a file through a file input ```bash /browser upload "input[type='file']" "~/path/to/file.pdf" ``` ## Tips & Best Practices 1. **Always start with `open`** - Initialize the browser session before other commands 2. **Use specific selectors** - Prefer `data-testid` attributes over generic selectors 3. **Check screenshots between steps** - Verify page state after interactions 4. **Increase timeout for slow operations** - PDF extraction may need 30-60 seconds 5. **Use inspect to understand page structure** - Before clicking/filling, inspect the element 6. **Handle async operations** - Use `wait` for dynamically loaded content 7. **Use text matching for buttons** - `button:has-text('Submit')` is often more reliable ## Example: Complete Feature Test ```bash # Phase 1: Setup /browser open http://localhost:3000/summary-charges/add-charges?brand=TCT # Phase 2: Verify UI loaded /browser inspect ".dialog-header" /browser screenshot # Phase 3: Test 3PL selector /browser click "button:has-text('Import from PDF')" /browser screenshot # Phase 4: Select instruction set /browser select ".instruction-select" "XPO Warehouse" /browser screenshot # Phase 5: Upload PDF /browser upload "input[type='file']" "~/Downloads/test.pdf" /browser screenshot # Phase 6: Trigger extraction /browser click "button:has-text('Extract Charges')" # Phase 7: Wait and verify /browser wait ".extracted-charges-table" --timeout 30000 /browser screenshot /browser inspect "table" ``` ## Troubleshooting **Element not found:** - Check the selector syntax - Use `inspect` to understand the page structure - Try text matching instead of specific selectors **Click/fill not working:** - Ensure element is visible and clickable - Check if element requires scrolling into view - Verify element is not disabled or hidden **Timeout waiting for element:** - Increase the timeout value - Check console for JavaScript errors - Use `screenshot` to see current page state **File upload fails:** - Verify file path exists (use absolute or ~/ paths) - Check file input accepts the file type - Ensure upload input is visible and accessible ## Integration with Development This skill works best when: - You have a dev server running (e.g., `pnpm run dev`) - You know the URLs to test (localhost ports documented in project) - You have test files available (PDFs, images, etc.) - You're iterating on UI features and need quick verification Use this skill in Claude Code workflows to: 1. Verify UI changes work as expected 2. Debug form interactions 3. Test file upload functionality 4. Screenshot progress for documentation 5.
