AI AGENT TIPS:
  - Use --format text instead of JSON for 3-10x fewer tokens
  - Use eval --stringify '<expr>' to get actual values instead of actor grip metadata
  - Use styles --properties color,display,font-size (bare styles dumps ~500 properties)
  - Use a11y summary for a flat list instead of the full tree (can be 400+ lines)
  - Use snapshot --depth 3 for a quick page overview
  - Use dom \"sel\" --text-attrs to get both text content and attributes together
  - Follow the contextual hints (-> lines) for suggested next commands

COOKBOOK:
  # Launch Firefox (safe alongside your normal browser)
  ff-rdp launch
  ff-rdp launch --headless
  ff-rdp launch --headless --auto-consent

  # Navigate and verify
  ff-rdp navigate https://example.com --wait-text \"Welcome\"
  ff-rdp eval \"document.title\"
  ff-rdp dom \"h1\" --text

  # Fill and submit a form
  ff-rdp type \"input[name=email]\" \"user@example.com\" --clear
  ff-rdp type \"input[name=password]\" \"secret\" --clear
  ff-rdp click \"button[type=submit]\"
  ff-rdp wait --text \"Dashboard\" --wait-timeout 10000

  # Full page audit
  ff-rdp navigate https://example.com --with-network
  ff-rdp perf audit
  ff-rdp a11y contrast --fail-only
  ff-rdp network --detail --limit 10
  ff-rdp screenshot -o audit.png

  # Performance
  ff-rdp perf vitals --jq '.results.lcp_ms'
  ff-rdp perf --all --jq '[.results | sort_by(-.duration_ms) | limit(5;.) | {url,duration_ms}]'
  ff-rdp perf compare https://a.example https://b.example --label \"Before,After\"

  # Network debugging
  ff-rdp network --detail --jq '[.results[] | select(.status >= 400) | {url,status}]'
  ff-rdp network --follow --filter \".js\"

  # Console monitoring
  ff-rdp console --level error --jq '.results[].message'
  ff-rdp console --follow --level error

  # Scrolling (overflow containers, lazy-loaded content)
  ff-rdp scroll by --page-down
  ff-rdp scroll container \".sidebar\" --to-end
  ff-rdp scroll until \".load-more-sentinel\" --timeout 10000
  ff-rdp scroll text \"Contact Us\"

  # Accessibility
  ff-rdp a11y summary --format text
  ff-rdp a11y contrast --fail-only
  ff-rdp a11y --interactive --jq '[.. | select(.role? == \"link\") | .name]'

  # DOM and CSS inspection
  ff-rdp dom \"a[href]\" --text-attrs
  ff-rdp dom stats --jq '.results.node_count'
  ff-rdp computed h1 --prop color
  ff-rdp styles \"h1\" --properties color,display,font-size

OUTPUT FORMAT:
  All commands return JSON: {\"results\": ..., \"total\": N, \"meta\": {...}}
  Truncated output adds: {\"truncated\": true, \"hint\": \"showing 20 of 84, use --all\"}
  Use --jq to filter the envelope: --jq '.results[0]', --jq '.total'
  Use --format text for human-readable tables (mutually exclusive with --jq)
  Use --detail for per-entry output on list commands (default is summary view)
  Contextual hints suggest follow-up commands: \"hints\": [...] in JSON, -> lines in text
  Hints default: on for --format text, off for JSON. Override: --hints / --no-hints
  --jq always suppresses hints (pipeline needs clean data)

TROUBLESHOOTING:
  Zero results:
    network returns 0 -> page loaded before connection; use navigate --with-network
    console returns 0 -> use --follow to stream, or eval 'console.log(\"test\")'
    cookies returns 0 -> consent banner may be blocking; use launch --auto-consent

  Connection errors:
    \"could not connect\" -> run ff-rdp launch first (safe alongside normal browser)
    Timeout -> increase --timeout or check --port matches the launched instance";

Three input modes (exactly one required):
  Positional:  ff-rdp eval 'document.title'
  From file:   ff-rdp eval --file script.js
  From stdin:  echo 'document.title' | ff-rdp eval --stdin

Prefer --file or --stdin for scripts that contain shell metacharacters,
optional chaining (?.), template literals, or multi-line statements — shell
quoting can mangle them and produce a SyntaxError at column 1.

    #[command(long_about = "Show network requests captured by the WatcherActor.

In direct mode (--no-daemon), only requests made after the connection is
established are reliably captured. When no live network events are available
(e.g. the page finished loading before ff-rdp connected), the command
automatically falls back to the Performance API to retrieve historical
resource timing data. Fallback entries have source=performance-api in the
output metadata and lack HTTP status codes.

Recommended workflows:
  - Daemon mode (default): run `ff-rdp` without --no-daemon so the daemon
    buffers events continuously across commands.
  - Navigate with capture: use `ff-rdp navigate --with-network <url>` to
    start network monitoring before the page load begins.

The --filter and --method flags narrow results after capture; they do not
affect which requests Firefox records.

uses the -no-remote flag and a separate profile, so the new instance is

enabled. Use --profile to reuse an existing profile, or --temp-profile to
make the temporary profile explicit.
