Defined in: src/types/agent.ts:97

Union type representing all possible streaming events from an agent. This includes model events, tool events, and agent-specific lifecycle events.

This is a discriminated union where each event has a unique type field, allowing for type-safe event handling using switch statements.

Note: All agent lifecycle events are Hook Event instances, providing consistent structure with agent reference and extensibility features.
