Class: PlanningEngine

Defined in: packages/agentos/src/core/planning/PlanningEngine.ts:194

Implementation of the AgentOS Planning Engine.

Features:

  • ReAct (Reasoning + Acting) pattern for interleaved planning and execution
  • Plan-and-Execute for upfront planning
  • Tree-of-Thought for exploring multiple reasoning paths
  • Self-reflection and plan refinement
  • Checkpoint and rollback support
  • Human-in-the-loop integration points
