Usage: impeccable detect [options] [file-or-dir-or-url...]

Scan files or URLs for UI anti-patterns and design quality issues.

Options:
  --json              Output results as JSON
  --quiet             In text mode, only print the final findings count
  --scope <name>      Only report rules in the given design domain
                      (type, layout). Comma-separated.
  --viewport <WxH>    Browser viewport for URL scans (default 1280x800),
                      e.g. --viewport 390x844 for a mobile-width pass
  --no-config         Do not apply project config, detector ignores, inline
                      ignore comments, or DESIGN.md
  --no-inline-ignores Do not honor in-file impeccable-disable* ignore comments
  --no-design-system  Do not load local DESIGN.md / .impeccable/design.json context
  --no-advisory       Suppress advisory findings entirely (e.g. em-dash overuse)
  --help              Show this help message

Advisory findings:
  Some rules are advisory: detected and listed in a separate section, but never
  counted as failures and never changing the exit code. They stay out of the
  failure count so they never block automation. --no-advisory hides them.

Output streams:
  Human-readable findings go to stderr so stdout stays available for structured
  output. Use --json for JSON on stdout, or redirect text with 2> findings.txt.

Exit status:
  0  Scan completed with no primary findings (advisories may still be listed)
  1  At least one requested target could not be scanned
  2  Scan completed with primary findings
  Operational failure takes precedence when a multi-target scan is partial.

Project config:
  Respects .impeccable/config.json and .impeccable/config.local.json detector
  settings: detector.ignoreRules, detector.ignoreFiles, detector.ignoreValues,
  and detector.designSystem.enabled.

Inline ignores:
  In-file comments waive a finding where it lives and travel with the file:
    <!-- impeccable-disable overused-font -- exported brand doc -->
    .brand { font-family: Inter } /* impeccable-disable-line overused-font */
    // impeccable-disable-next-line bounce-easing: intentional bounce
  impeccable-disable applies to the whole file; -line / -next-line are scoped.
  List one or more rule ids (comma-separated), or omit them / use * for all.

Detection modes:
  HTML files     Static HTML/CSS analysis (default, catches linked CSS)
  Non-HTML files Regex pattern matching (CSS, JSX, TSX, etc.)
  URLs           Puppeteer full browser rendering (auto-detected;
                 http(s):// and file:// URLs; accessible linked CSS included)

Examples:
  impeccable detect src/
  impeccable detect index.html
  impeccable detect https://example.com
  impeccable detect --json .
  impeccable detect --no-config src/
