sendMessageWithContext()

sendMessageWithContext(messageText, context?): Promise<A2AMessageResult>

Defined in: _worktrees/docs-release/gaunt-sloth/packages/agent/src/modules/a2a/A2AClientWrapper.ts:135

BATCH-14 — send one message and return its text ALONG WITH the A2A contextId/taskId needed to thread a multi-turn conversation. Reads the real @a2a-js/sdk result shapes rather than a loose envelope:

A Message result carries its text in parts and contextId/taskId directly (both optional, and empty-string when absent in the v1.0 proto model).
A Task result — what Google ADK agents commonly return — carries text in status.message.parts (falling back to the last artifact’s parts), contextId (required), and the taskId as Task.id.

context.contextId/taskId are attached to the OUTGOING message only when defined, so a first-turn send stays byte-identical to a contextless one.

Parameters

messageText

string

The message to send to the agent.

context?

A2ASendContext

Optional context/task ids to continue an existing conversation.

Returns

Promise<A2AMessageResult>

The agent’s text answer plus the context/task ids from its response.
