Reasoning vs. Execution
In the world of AI agents, planning is the bridge between a thought and an action. Without a plan, an agent is reactive--it might take a step that feels right in the moment but leads to a end. Planning allows the agent to "Look Ahead" and evaluate different sequences of actions before committing to the first one.
Conclusion
Planning is what gives AI "Purpose." By thinking through the future consequences of current actions, agents can navigate the complexity of the real world with precision and confidence.
