Question

Is Channels in the Cloudflare agents package stable, and what's its import path?

Answer key

A correct answer says

The `agents/channels` entry point is gone; Channels now lives under `agents/experimental/channels` (Slack, Telegram and Email under its subpaths) and is experimental.

The stale answer

Import Channels (ChannelHost, Slack/Telegram/Email adapters) from `agents/channels`.

Answer

No, Channels isn't stable. In the installed `agents` package (0.27.0 per this project's lessons file), it's only exported under an experimental path. The main import is `agents/experimental/channels`. Each transport has its own subpath: `agents/experimental/channels/email`, `/slack`, `/telegram` and `/web`, and the web one also has `/web/client` and `/web/ai-sdk`. I found this in `node_modules/agents/package.json` and there's no non-experimental export, so expect the API to change between releases.

Grade

correct

The judge's reason: It says Channels is experimental, gives the `agents/experimental/channels` path with Slack/Telegram/Email subpaths, and notes there is no non-experimental export.
