With several NetBox instances, netssh offers "prod/fsn1-bx1…" for the typed text "fsn1". compadd discarded these matches because they do not start with the typed word, so <Tab> found nothing. The matcher 'l:|=*' lets zsh accept text before the typed word; netssh has already filtered the candidates. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
