286-295: Remove stream-mode check from the multi-stdin exclusivity block.The inner
if options.Stream { ... "argument stdin not supported in stream mode" }only triggers when two flags use stdin and is redundant/confusing since stream-mode constraints are enforced below. Keep this block focused on exclusivity across flags.Apply this diff:
- // stdin can be set only on one flag - if (argumentHasStdin(options.Domains) && argumentHasStdin(options.WordList)) || - (argumentHasStdin(options.Domains) && argumentHasStdin(options.Hosts)) || - (argumentHasStdin(options.WordList) && argumentHasStdin(options.Hosts)) { - if options.Stream { - gologger.Fatal().Msgf("argument stdin not supported in stream mode") - } - gologger.Fatal().Msgf("stdin can be set for one flag") - } + // stdin can be set only on one flag + if (argumentHasStdin(options.Domains) && argumentHasStdin(options.WordList)) || + (argumentHasStdin(options.Domains) && argumentHasStdin(options.Hosts)) || + (argumentHasStdin(options.WordList) && argumentHasStdin(options.Hosts)) { + gologger.Fatal().Msgf("stdin can be set for one flag") + }

303-305: Clarify the stream-mode error for -l with a usage hint.Suggest making the message actionable so users know how to feed stdin in stream mode.
- gologger.Fatal().Msgf("hosts not supported in stream mode") + gologger.Fatal().Msgf("hosts (-l) not supported in stream mode; pipe input instead (e.g., dnsx -stream < hosts.txt)")internal/runner/runner.go (1)
256-259: Add empty-item guard and clearer empty-input error
- In the
if sc == nilblock, distinguishHosts == ""and return
errors.New("no input provided: use -l <file|comma-separated values> or pipe via stdin")instead of the opaque"empty argument".- In the host loop, immediately skip blank entries after trimming:
for item := range sc { item := normalize(item) if item == "" { continue } … }

97-97: Help text update for -l looks good.Accurately reflects comma-separated support and aligns with -d/-w descriptions.

This seems to break stdin support:
