Planning is one of the core behaviors that makes an agent feel agentic. Instead of producing a single response, the system determines what needs to happen first, second, third, and what information or tool calls are required along the way.
For a business, planning matters because workflows are sequences. A lead does not just need a reply. It may need enrichment, scoring, routing, CRM creation, follow-up, scheduling, and manager visibility. Planning lets agents operate across the workflow instead of handling one isolated prompt.
