Configuration:
  agent-browser looks for agent-browser.json in these locations (lowest to highest priority):
    1. ~/.agent-browser/config.json      User-level defaults
    2. ./agent-browser.json              Project-level overrides
    3. Environment variables             Override config file values
    4. CLI flags                         Override everything

  Use --config <path> to load a specific config file instead of the defaults.
  If --config points to a missing or invalid file, agent-browser exits with an error.

  Boolean flags accept an optional true/false value to override config:
    --headed           (same as --headed true)
    --headed false     (disables "headed": true from config)

  Extensions from user and project configs are merged (not replaced).

  Example agent-browser.json:
    {{"headed": true, "proxy": "http://localhost:8080", "profile": "./browser-data"}}

Install (recommended, fastest - native Rust CLI):
  npm install -g agent-browser
  agent-browser install                  # Download Chromium (first time)

Try without installing (slower, routes through Node.js):
  npx agent-browser open example.com

Examples:
  agent-browser open example.com
  agent-browser snapshot -i              # Interactive elements only
  agent-browser click @e2                # Click by ref from snapshot
  agent-browser fill @e3 "test@example.com"
  agent-browser find role button click --name Submit
  agent-browser get text @e1
  agent-browser screenshot --full
  agent-browser screenshot --annotate    # Labeled screenshot for vision models
  agent-browser wait --load networkidle  # Wait for slow pages to load
  agent-browser --cdp 9222 snapshot      # Connect via CDP port
  agent-browser --auto-connect snapshot  # Auto-discover running Chrome
  agent-browser --color-scheme dark open example.com  # Dark mode
  agent-browser --profile ~/.myapp open example.com    # Persistent profile
  agent-browser --session-name myapp open example.com  # Auto-save/restore state

Command Chaining:
  Chain commands with && in a single shell call (browser persists via daemon):

  agent-browser open example.com && agent-browser wait --load networkidle && agent-browser snapshot -i
  agent-browser fill @e1 "user@example.com" && agent-browser fill @e2 "pass" && agent-browser click @e3
  agent-browser open example.com && agent-browser wait --load networkidle && agent-browser screenshot page.png

iOS Simulator (requires Xcode and Appium):
  agent-browser -p ios open example.com                    # Use default iPhone
  agent-browser -p ios --device "iPhone 15 Pro" open url   # Specific device
  agent-browser -p ios device list                         # List simulators
  agent-browser -p ios swipe up                            # Swipe gesture
  agent-browser -p ios tap @e1                             # Touch element
