Agent Browser — Page Crawling and Data Extraction

Installation

CLAWBOT must ensure agent-browser is available before any browsing task:

which agent-browser || npm install -g agent-browser
agent-browser install

Purpose

CLAWBOT uses this in Research Step 2 (explore & collect) when it encounters pages that require JS rendering. Suitable for: project official websites, DApp pages, and dynamic pages on aggregator platforms.

Core Workflow

# 1. Open & wait
agent-browser open <url>
agent-browser wait --load networkidle

# 2. Snapshot — get interactive elements with @refs
agent-browser snapshot -i

# 3. Extract content
agent-browser get text @e1         # element text
agent-browser get html @e1         # innerHTML
agent-browser get attr @e1 href    # attribute
agent-browser get title            # page title
agent-browser get url              # current URL
agent-browser get count ".item"    # count matching elements

# 4. Interact
agent-browser click @e1            # click
agent-browser fill @e2 "keyword"   # fill input (clears first)
agent-browser scroll down 500      # scroll
agent-browser scrollintoview @e1   # scroll element into view
agent-browser press Enter          # press key

# 5. Capture evidence
agent-browser screenshot --full    # full-page screenshot
agent-browser pdf output.pdf       # save as PDF

# 6. Close
agent-browser close

Wait Strategies

agent-browser wait @e1                  # wait for element
agent-browser wait 2000                 # wait milliseconds
agent-browser wait --text "Success"     # wait for text
agent-browser wait --url "/dashboard"   # wait for URL pattern
agent-browser wait --load networkidle   # wait for network idle

Semantic Locators (alternative to @refs)

agent-browser find role button click --name "Submit"
agent-browser find text "Sign In" click
agent-browser find label "Email" fill "user@test.com"

Output Format

Add --json for structured output:

agent-browser snapshot -i --json
agent-browser get text @e1 --json

Notes

• @ref changes after page navigation; always re-snapshot
• Use fill for inputs (clears old value), not type
• For dynamic pages, wait --load networkidle before snapshot
• Use --headed to see the browser window for debugging
