Session event “assistant.fusion_phase_activity”. Experimental content-safe activity signal for a running HydraFusion phase.

Experimental. This type is part of an experimental wire-protocol surface and may change or be removed in future SDK or CLI releases.

Fields

activity: FusionPhaseActivityKind

Kind of real activity observed.

conversation_scope: FusionConversationScope

Conversation scope in which the phase executes.

fusion_id: String

Identifier of the HydraFusion turn containing the phase.

pattern: FusionPattern

HydraFusion orchestration pattern containing the phase.

phase_id: String

Stable identifier for the concrete phase.

phase_kind: FusionPhaseKind

Kind of phase currently executing.

role: String

Semantic role assigned to the phase.

tool_call_id: Option<String>

Opaque hashed correlation token for matching tool-started and tool-completed activity within this Fusion activity stream. It is not the tool call identifier exposed by tool lifecycle events.

total_response_size_bytes: Option<i64>

Cumulative private response bytes observed for this model call. The event never includes response text.
