Share an agent on the Marketplace; cloning it earns you credits.
Open the builder: Agents → "Create an agent".
Pick a template to start from, e.g. "Find & email new prospects".
Open the "..." menu and click "Publish to marketplace".
Give it a marketplace name and description, choose which sequences to share with it, and accept the terms.
Click "Publish". Your contacts and credentials are never shared, only the steps.
