Planner agent
The multi-agent role responsible for generating a proposed strategy given the current context. Receives episodic memories, active goals, and policy state. Does not evaluate whether the plan is good - that is the critic's role. Its proposal enters arbitration alongside the executor's and critic's outputs.
The planner agent's bounded responsibility is strategy generation: given the triggering event, retrieved episodic memories about past similar situations, active goals, and the current policy vector, it produces a coherent proposed course of action. It is not responsible for determining whether the plan is good (that is the critic's job), how to implement it in detail (that is the executor's job), or what outcomes it will produce (that is the world-model agent's job). This separation of concerns means the planner can be evaluated, tuned, and improved independently of the other roles. Role-specific retrieval gives the planner episodic memories - records of what happened in past similar situations - rather than the procedural or contradiction records that serve the executor and critic better. The planner's proposal is one of the candidates that arbitration scores and selects from.
