Method Details

init

public void init(InitPlanningContext initPlanningContext)

Specified by:

init in interface Planner

firstAction

public Action firstAction(PlanningContext planningContext)

Specified by:

firstAction in interface Planner

nextAction

public Action nextAction(PlanningContext planningContext)

Specified by:

nextAction in interface Planner

restoreExecutionState

public void restoreExecutionState(Map<String,Object> state)

GoalOrientedPlanner does not persist execution state because firstAction(PlanningContext) recomputes the path from the current scope state via graph search. On recovery, completed agents' outputs are already in scope, so the search produces a shorter path containing only the remaining agents. The cursor resets to 0 naturally, making state persistence unnecessary and potentially harmful (a stale cursor could point beyond the bounds of the recomputed path).

restoreExecutionState in interface Planner

topology

public AgenticSystemTopology topology()
