        Description:
          Print usage from enabled providers as text (default) or JSON. Honors your in-app toggles.
          Output format: use --json (or --format json) for JSON on stdout; use --json-output for JSON logs on stderr.
          When --source is auto/web (macOS only), CodexBar uses browser cookies to fetch web-backed data:
          - Codex: OpenAI web dashboard (usage limits, credits remaining, code review remaining, usage breakdown).
            Auto falls back to Codex CLI only when cookies are missing.
          - Claude: claude.ai API.
            Auto falls back to Claude CLI only when cookies are missing.
          Token accounts are loaded from ~/.codexbar/config.json.
          Use --account or --account-index to select a specific token account, or --all-accounts to fetch all.
          Account selection requires a single provider.

        Global flags:
          -h, --help      Show help
          -V, --version   Show version
          -v, --verbose   Enable verbose logging
          --no-color      Disable ANSI colors in text output
          --log-level <trace|verbose|debug|info|warning|error|critical>
          --json-output   Emit machine-readable logs (JSONL) to stderr

        Examples:
          codexbar usage
          codexbar usage --provider claude
          codexbar usage --provider gemini

        Description:

          Uses cached scan results unless --refresh is provided.
