fix(think): stop posting a `...` placeholder before messenger replies (#2310) by threepointone · Pull Request #2324 · cloudflare/agents

threepointone · 2026-09-23T14:18:19Z

Problem

When an adapter cannot stream natively, Chat SDK posts a placeholder ... message and then edits in the reply. Slack uses the first text of a message as its notification preview, so every Think messenger reply notified users with ....

Fix

The runtime's Chat is constructed with fallbackStreamingPlaceholderText: null, so the first post already contains reply text.
Threads revived during recovery are rebuilt with the same setting, because ThreadImpl.fromJSON drops it.
docs/think/messengers.md describes the delivery behaviour.
The chat-sdk-messenger example sets the option on its own Chat. Its recovery path revived threads with bot.reviver(), which drops the setting too, so it now rebuilds them with a small reviveReplyThread() helper.

A new ThinkMessengerDeliveryTestAgent drives real webhooks through the runtime's own Chat, handlers, and adapter post/edit fallback. It records both what the model was asked and what the adapter sent, so the live delivery path is now covered end to end. Later PRs in this stack reuse it.

Validation: End-to-end delivery tests assert the first post carries reply text and never ..., for both live and revived threads. A new example test streams a reply into a revived thread; it fails with bot.reviver() alone. The messenger suite, the example's tests, and pnpm run check passed.

Fixes #2310

Stacked PR 3 of 10. Base: #2323.

commit: 05a40ff

…#2310) Chat SDK posts `...` and edits it when an adapter has no native stream, and Slack keeps that first text as the notification preview. Construct the runtime's Chat with `fallbackStreamingPlaceholderText: null`, and rebuild recovered threads with the same setting since `ThreadImpl.fromJSON` drops it. Adds ThinkMessengerDeliveryTestAgent, which drives real webhook replies through the runtime's own Chat, so the live path is covered end to end. The chat-sdk-messenger example sets the same option on its own Chat and rebuilds recovered threads with it, because bot.reviver() drops it too. Co-authored-by: Cursor <cursoragent@cursor.com>

…n recovery With no placeholder, an adapter without native streaming waits for text before posting, so a turn with no text ended in a blank post that Telegram rejects. TextStreamCallback now streams emptyText when a completed turn has none. reviveThread no longer went through chat.reviver(), which re-registers the Chat singleton the lazy thread resolves its adapter from; register it directly. Co-authored-by: Cursor <cursoragent@cursor.com>

A lazily resolved thread reads the module-global Chat singleton on first use, and another runtime in the isolate can register its Chat while recovery awaits the target. Construct the thread with the definition's adapter and this Chat's state adapter instead. Co-authored-by: Cursor <cursoragent@cursor.com>
