    long_about = "agentchrome is a command-line tool for browser automation via the Chrome DevTools \
        Protocol (CDP). It provides subcommands for connecting to Chrome/Chromium instances, \
        managing tabs, navigating pages, inspecting the DOM, executing JavaScript, monitoring \
        console output, intercepting network requests, simulating user interactions, filling forms, \
        emulating devices, and collecting performance metrics.\n\n\
        Designed for AI agents and shell scripting, every subcommand produces structured JSON \
        output on stdout and structured JSON errors on stderr. Global flags control connection \
        settings, output format, and target tab selection.",
    after_long_help = "\
QUICK START:
  # Connect to a running Chrome instance
  agentchrome connect

  # Launch a new headless Chrome and connect
  agentchrome connect --launch --headless

  # List open tabs and navigate to a URL
  agentchrome tabs list
  agentchrome navigate https://example.com

  # Take a full-page screenshot
  agentchrome page screenshot --full-page --file shot.png

  # Execute JavaScript and get the result
  agentchrome js exec \"document.title\"

  # Capture the accessibility tree and fill a form field
  agentchrome page snapshot
  agentchrome form fill s5 \"hello@example.com\"

  # Monitor console output in real time
  agentchrome console follow --timeout 5000

EXIT CODES:
  0  Success
  1  General error (invalid arguments, internal failure)
  2  Connection error (Chrome not running, session expired)
  3  Target error (tab not found, no page targets)
  4  Timeout error (navigation or trace timeout)
  5  Protocol error (CDP protocol failure, dialog handling error)

ERROR HANDLING:
  Every non-zero exit emits exactly one JSON object on stderr. The stable
  shape is:
    {\"error\": \"<human-readable message>\", \"code\": <1..5>}
  Some paths enrich the payload with optional fields (stable fields remain
  present) — for example form fill against a non-fillable element:
    {\"error\": \"...\", \"code\": 1, \"kind\": \"not_fillable\",
     \"element_type\": {\"tag\": \"div\", \"role\": null},
     \"suggested_alternatives\": [\"'agentchrome interact click'\"]}
  Exit-code meanings: 0=success, 1=general, 2=connection, 3=target,
  4=timeout, 5=protocol. Success-path stdout remains JSON and stderr stays
  empty; stderr is reserved for the error object only.

  AGENTCHROME_PORT     CDP port number (default: 9222)
  AGENTCHROME_HOST     CDP host address (default: 127.0.0.1)
