Type Alias: DispatchRunnerObservabilityHooks

type DispatchRunnerObservabilityHooks = {
  dispatchEnd: [[DispatchEndEvent], []];
  dispatchStart: [[DispatchStartEvent], []];
  error: [[BaseException], []];
  iterationEnd: [[IterationEndEvent], []];
  iterationStart: [[IterationStartEvent], []];
  log: [[LogEvent], []];
  toolExecutionEnd: [[ToolExecutionEndEvent], []];

Observability hook events on @nhtio/adk!DispatchRunner.

Remarks

Instrumentation-only events. Register handlers via the observers field of the dispatch input. Removing an observer does not affect dispatch correctness.
