Publication copy:
LinkedIn Growth is an agent skill for hands-off, controlled LinkedIn network growth. The user defines a LinkedIn or Sales Navigator search plus an ideal-lead profile; the skill imports candidates, qualifies every lead with recorded reasoning, stores the pipeline locally, assigns leads across one or more accounts, sends connection invites during active hours, tracks acceptances, and withdraws unanswered requests. It is built for steady qualified growth rather than one-off blasting.
