Agent Browser Assistant

An intelligent browser control assistant providing browser automation, data scraping, and testing capabilities.

Use Cases

Opening web pages, clicking/typing/scrolling, taking screenshots/recordings, extracting web content, exporting table data, automated form filling, batch operations, scheduled tasks, login authentication, UI testing, regression testing.

Quick Start

Use the browser tool for all browser operations:

# Open a web page
browser(action="open", url="https://example.com")

# Take a screenshot
browser(action="screenshot")

# Click an element
browser(action="act", kind="click", ref="button-submit")

# Type text
browser(action="act", kind="type", ref="input-username", text="user@example.com")

# Scroll the page
browser(action="act", kind="scroll", y=500)

# Get a page snapshot
browser(action="snapshot")

Core Capabilities

1. Page Operations

Operation	Description	Example
open	Open a specified URL	action="open", url="..."
snapshot	Get page structure	action="snapshot"
screenshot	Take a page screenshot	action="screenshot"
navigate	Navigate to a URL	action="navigate", url="..."
close	Close a tab	action="close", targetId="..."

2. Element Interaction

Use the act operation for page interaction:

• click: Click an element (ref: element reference)
• type: Type text (ref: input reference, text: content)
• press: Press a keyboard key (key: key name)
• hover: Hover over an element
• select: Select from a dropdown
• fill: Fill a form (fields: field dictionary)
• scroll: Scroll the page (x/y: coordinates)

3. Data Scraping

Extract data from web pages:

# Get a page snapshot to analyze structure
browser(action="snapshot")

# Extract table data - using selector
browser(action="act", kind="evaluate", selector="table.data", fn="Array.from(document.querySelectorAll('tr')).map(r => Array.from(r.querySelectorAll('td')).map(c => c.innerText))")

4. Automated Workflows

Automated form filling:

browser(action="act", kind="fill", fields=[
    {"ref": "input-email", "value": "user@example.com"},
    {"ref": "input-password", "value": "password123"}
])
browser(action="act", kind="click", ref="button-login")

Batch operations:

# Iterate through list items
for i in range(1, 6):
    browser(action="act", kind="click", ref=f"item-{i}")

5. Testing Capabilities

UI testing scenarios:

• Regression Testing: Verify that page functionality works correctly
• Performance Monitoring: Page load time
• Element Existence Check: Verify that key elements are visible

Advanced Usage

Waiting for Page Load

browser(action="act", kind="wait", loadState="domcontentloaded", timeMs=5000)

Handling Dialogs

browser(action="dialog", kind="accept")  # Confirm
# or
browser(action="dialog", kind="dismiss")  # Cancel

File Upload

browser(action="upload", ref="input-file", paths=["C:/path/to/file.pdf"])

PDF Export

browser(action="pdf", path="C:/output/page.pdf")

Configuration Options

Parameter	Description	Default
profile	Browser profile	"openclaw"
target	Browser target	"sandbox"
slowly	Slow motion mode	false
timeoutMs	Timeout duration	30000

Common Selector Patterns

• Button: button[type="submit"], #submit-btn
• Input: input[name="email"], #username
• Link: a[href*="login"]
• Table: table.data tr
• List: .item-list li

Notes

1. Use snapshot to get page structure before performing element operations
2. Dynamic content may require waiting for it to finish loading
3. For logged-in state operations, use profile="user" to reuse the user's browser
4. For large-scale data scraping, consider pagination to avoid timeouts
