Granular events emitted by the assistant during a streaming turn.

Carried inside RpcEvent::MessageUpdate.

Variants

ResponseStart

ResponseReset

TextDelta

An incremental text chunk from the assistant’s response.

Fields

delta: String

The text fragment.

ThinkingDelta

An incremental thinking/reasoning chunk (extended thinking mode).

Fields

delta: String

The thinking fragment.

ToolcallStart

A tool call has started streaming. Subsequent AssistantEvent::ToolcallInputDelta frames carry the JSON input.

Fields

tool_id: String

Model-assigned opaque identifier for this tool call.

tool_name: String

The tool being invoked.

ToolcallInputDelta

An incremental JSON fragment of a tool call’s input.

Fields

tool_id: String

Matches the tool_id from AssistantEvent::ToolcallStart.

delta: String

Raw JSON fragment (not yet a complete object).

ToolcallInput

The complete, finalised input for a tool call.

Fields

tool_id: String

Matches the tool_id from AssistantEvent::ToolcallStart.

input: Value

The fully parsed JSON input value.

ToolcallResult

The result returned by tool execution.

Fields

tool_id: String

Matches the tool_id from AssistantEvent::ToolcallStart.

result: String

The serialised tool result string.
