Planning Agent
In one line
A planning agent is an agent that first drafts a multi-step plan for a goal and then executes it step by step, calling tools as needed.
Going deeper
A planning agent splits work into two stages — draft a plan, then execute — instead of deciding the next move on every step the way ReAct does. Patterns like Plan-and-Execute or Tree-of-Thoughts fall into this family.
It shines on multi-step workflows. Campaign planning, content drafting and scheduling, ops automation — anything with many ordered steps gets more stable when a plan is laid out up front rather than improvised.
The catch is that a bad plan poisons the entire execution. Production setups usually separate the Planner from the Executor and add a human-in-the-loop checkpoint to review the plan before tools start firing.
