feat(channels): stream outbound messages by cjol · Pull Request #2180 · cloudflare/agents

cjol · 2026-08-28T20:58:09Z

This PR adds outbound message streaming to @cloudflare/channels, including native Slack and Telegram streaming, composite routing, and an AI SDK adapter.

Why

Channels currently wait for a complete model response before delivering anything, even when the destination supports progressive rendering.
Streaming needs transport-neutral chunks because provider-specific payloads do not compose across Slack, Telegram, fallback routes, and fanout routes.
A Channel owns stream consumption and terminal provider calls. This ensures an interrupted generation still finalizes its provider message instead of leaving a draft or streaming message unfinished.
Channels that cannot stream collect the text and use ordinary delivery, so callers use one Host API regardless of transport capability.
Slack cannot stream at the top level of an ordinary channel. The adapter collects and posts one ordinary message there, while threads and direct messages use Slack's native streaming methods.

Public API Surface

Symbol	Kind	Notes
`ChannelChunk`	Type	Neutral `text`, `reasoning`, `tool`, and `source` stream chunks
`ChannelChunkSource`	Type	Normalized `ReadableStream<ChannelChunk>` input
`ChannelDeliveryOptions`	Type	Wraps caller-owned delivery context
`ChannelStreamOptions`	Type	Supplies an optional title and delivery context
`Channel.stream`	Optional method	Lets a Channel consume and finalize a streamed answer
`OutboundResolver.stream`	Method	Recursively streams through composite Channels
`ChannelHost.stream`	Method	Resolves a destination and streams or collects before delivery
`consumeChunks`	Function	Finalizes exactly once after normal or interrupted consumption
`ChunkConsumer`	Type	Defines chunk and finalization callbacks
`StreamOutcome`	Type	Reports normal or interrupted stream completion
`toChannelChunks`	Function	Maps an AI SDK `fullStream` to Channel chunks

DeliveryResult now permits a reference on its uncertain arm.

deliver now takes ChannelDeliveryOptions as its third argument instead of a bare ChannelDeliveryContext.

Architectural Changes

ReadableStream<ChannelChunk>
             |
        ChannelHost
             |
       +-----+------+
       |            |
 Channel.stream   collect text
       |            |
 native provider  Channel.deliver

Composite Channels preserve the same contract:

fanout tees the source so each destination receives its own stream.
fallback retains consumed chunks and replays them after a confirmed failure.
uncertain stops fallback to avoid potentially duplicating partial delivery.

Code Changes

Slack uses chat.startStream, chat.appendStream, and chat.stopStream for threads and direct messages. Top-level channel streams collect into chat.postMessage.
Telegram uses sendMessageDraft for private-chat previews and always finishes with sendMessage, including after an interrupted generation.
The Host collects text for Channels without native streaming support and uses TextSegmentJoiner to preserve semantic spacing around tool and metadata boundaries.
The AI SDK adapter maps fullStream parts into neutral chunks and turns abort or error parts into abnormal stream completion.
Live fixtures independently observe Telegram, Slack top-level, Slack threads, and email through one shared provider matrix.

Compatibility

The third argument to deliver changed from:

ChannelDeliveryContext

to:

ChannelDeliveryOptions

Callers passing a delivery ID must wrap it:

host.deliver(surface, message, {
  delivery: { deliveryId }
});

+      return invalidSurface();
+    }
+
+    const channel = this.#configuredChannel(surface.channelKey);


🟡 Unknown destinations leave producers running

Unknown destinations make #configuredChannel throw before chunks is cancelled. Producers can retain timers or external resources after delivery has failed.

Suggested change

const channel = this.#configuredChannel(surface.channelKey);

let channel: Channel;

try {

channel = this.#configuredChannel(surface.channelKey);

} catch (error) {

await chunks.cancel().catch(() => {});

throw error;

}

+      typeof apiResponse.channel === "string" &&

🔴 Successful Slack streams truncate

callSlack rejects successful append and stop responses unless they repeat the channel and timestamp. The first append cancels the remaining answer, and the completed stream reports uncertain.

Prompt for agents

Slack Web API success payloads differ by method. chat.startStream returns the channel and timestamp needed to create a reference, while chat.appendStream and chat.stopStream can return only ok: true. Refactor callSlack in packages/channels/src/adapters/slack.ts so each caller validates the success shape appropriate to its method. Keep requiring channel and timestamp for chat.startStream and chat.postMessage, but accept an ok-only success for append and stop. Add tests whose append and stop responses contain only ok: true, matching the provider contract.

🟡 Direct-message approval replies fail

Direct-message approval surfaces omit the recipient IDs required by chat.startStream. Streaming a reply to those approval actions is rejected by Slack.

Suggested change

...(!isDirectMessage && {

recipientUserId: actorId,

recipientTeamId: teamId

})

recipientUserId: actorId,

recipientTeamId: teamId
