The Planner Decides the Next Best Move

The planner is the decision-making part of an agent system. Its job is to look at the goal, current state, and available tools, then decide the next step or sequence of steps. In simple tasks, planning might be minimal. In complex tasks, the planner may break the work into subgoals, choose which information to gather first, and adjust the plan if something changes. This is important because agents without planning can behave reactively and inconsistently. They may jump into actions too early or miss more efficient paths. A good planner improves structure, reduces wasted steps, and makes the system feel purposeful. In product design, the planner does not always have to create a full long-range strategy. Sometimes lightweight planning is enough. What matters is that the agent is not acting blindly.
