description	Minimal Chrome DevTools Protocol tools for browser automation and scraping. Use when you need to start Chrome, navigate pages, execute JavaScript, take screenshots, or interactively pick DOM elements.

Browser Tools

Minimal CDP tools for collaborative site exploration and scraping.

IMPORTANT: All scripts are located in ~/.factory/skills/browser/ and must be called with full paths.

Start Chrome

~/.factory/skills/browser/start.js              # Fresh profile
~/.factory/skills/browser/start.js --profile    # Copy your profile (cookies, logins)

Start Chrome on :9222 with remote debugging.

Navigate

~/.factory/skills/browser/nav.js https://example.com
~/.factory/skills/browser/nav.js https://example.com --new

Navigate current tab or open new tab.

Evaluate JavaScript

~/.factory/skills/browser/eval.js 'document.title'
~/.factory/skills/browser/eval.js 'document.querySelectorAll("a").length'

Execute JavaScript in active tab (async context).

IMPORTANT: The code must be a single expression or use IIFE for multiple statements:

• Single expression: 'document.title'
• Multiple statements: '(() => { const x = 1; return x + 1; })()'
• Avoid newlines in the code string - keep it on one line

Screenshot

~/.factory/skills/browser/screenshot.js

Screenshot current viewport, returns temp file path.

Pick Elements

~/.factory/skills/browser/pick.js "Click the submit button"

Interactive element picker. Click to select, Cmd/Ctrl+Click for multi-select, Enter to finish.

Usage Notes

• Start Chrome first before using other tools
• The --profile flag syncs your actual Chrome profile so you're logged in everywhere
• JavaScript evaluation runs in an async context in the page
• Pick tool allows you to visually select DOM elements by clicking on them
