Streaming event types (discriminated by ‘type’ field)

Variants

Message

Message event from agent

Fields

message: Message

The message content

context_id: Option<String>

Context identifier the message is associated with

kind: String

Type discriminator

final: bool

True if this is the final message for the task

TaskStatus

Task status update event

Fields

task_id: String

Task identifier

context_id: Option<String>

Context identifier the task is associated with

status: TaskStatus

The new status

kind: String

Type discriminator

final: bool

True if this is the terminal update for the task

TaskArtifact

Task artifact update event

Fields

task_id: String

Task identifier

artifact: Artifact

The artifact data

append: bool

If true, append parts to existing artifact; if false, replace

last_chunk: bool

If true, indicates this is the final update for the artifact

final: bool

Usually false for artifacts; can signal end concurrently with status

Unknown

Catch-all for unknown streaming event types added by the A2A spec.
