github-actions[bot] caab5c3843 chore(release): version packages (#805)
This PR was opened by the [Changesets
release](https://github.com/changesets/action) GitHub action. When
you're ready to do a release, you can merge this and the packages will
be published to npm automatically. If you're not ready to do a release
yet, that's fine, whenever you add more changesets to main, this PR will
be updated.


# Releases
## @chat-adapter/discord@4.38.0

### Minor Changes

- a0cba02: Add Vercel Connect credential resolvers and custom webhook
verification to the Discord adapter, with `create-chat-sdk --connect`
scaffolding for Discord bots.

### Patch Changes

- a94995e: Restore attachment downloads across Discord inbound message
paths.
- 4bdf721: Preserve content and attachments from forwarded Discord
message snapshots.
- Updated dependencies [0f24cc3]
- Updated dependencies [bdeb2bf]
- Updated dependencies [a0cba02]
- Updated dependencies [83ede7e]
- Updated dependencies [18d4a23]
  - chat@4.38.0
  - @chat-adapter/shared@4.38.0
## @chat-adapter/messenger@4.38.0

### Minor Changes

- 18d4a23: Add a shared thread API for marking messages as read across
WhatsApp, Messenger, and XChat.

Note for anyone calling `XchatAdapter.markAsRead()` directly: it now
rejects when a receipt fails instead of logging a warning and resolving.
Automatic read receipts are unaffected, since the adapter still catches
and logs those internally. If you call the method yourself without
awaiting it, add a `.catch()` so a failed receipt does not surface as an
unhandled rejection.

### Minor Changes

while retaining native webhook verification and scaffolding.

## @chat-adapter/telegram@4.38.0

### Minor Changes

- 0f24cc3: Preserve normalized replied-to message context and populate
it from Telegram replies.
- 7a1150c: Add outbound-only Vercel Connect authentication for Telegram
while retaining native webhook verification or polling.
- 3bbf3ff: Use post-and-edit streaming by default and make native
Telegram drafts opt-in. Streams now render the same way in every chat
type; set the new `nativeStreaming: true` config option to restore draft
previews in private chats.

The adapter now owns the post-and-edit loop so edits stay under
Telegram's per-chat rate limit. Edits are throttled to a 1100ms floor,
configurable with the new `streamingEditIntervalMs` option, and a
rate-limited final edit is retried once instead of failing the post.

### Patch Changes

- 1d2b78d: Deduplicate repeated Telegram webhook updates by their update
ID using the configured state adapter.
- 745fdf5: respect Telegram streaming rate limits and target XChat read
receipts exactly

### Minor Changes

- 83ede7e: add native message replies with WhatsApp contextual reply
support

WhatsApp, Messenger, and XChat.

and logs those internally. If you call the method yourself without
awaiting it, add a `.catch()` so a failed receipt does not surface as an
unhandled rejection.

## create-chat-sdk@0.4.0

verification to the Discord adapter, with `create-chat-sdk --connect`
scaffolding for Discord bots.
- 06b04ac: Add outbound-only Vercel Connect authentication for Notion

## @chat-adapter/gchat@4.38.0

### Patch Changes

- 2f40a32: Fix attachment downloads failing with a 400 when
`attachmentDataRef` is present

`fetchAttachmentData` called the Chat media endpoint without
`alt=media`, so it
returned resource metadata rather than file bytes and rejected the
arraybuffer
request with a bare 400. Every download by `resourceName` failed, which
is the
  path taken for any file uploaded directly to Chat.

The download path is also hardened: when `media.download` fails and the
attachment carries a `downloadUri`, the adapter now falls back to
fetching that
URL instead of rejecting, and failures with no fallback are routed
through the
shared error handling so a 429 surfaces as `AdapterRateLimitError` like
every
  other Chat API call.

create-chat-sdk

npm package: create-chat-sdk

Agent Stack MIT License

Scaffold a webhook-only Chat SDK bot project from the command line.

Documentation: chat-sdk.dev/docs/create-chat-sdk · Guides: vercel.com/kb/chat-sdk

Usage

npm create chat-sdk@latest my-bot

With another package manager:

pnpm create chat-sdk@latest my-bot
yarn create chat-sdk my-bot
bunx create-chat-sdk@latest my-bot

Non-interactive mode

Pass platform and state adapters with --adapter:

npm create chat-sdk@latest -- my-bot --adapter slack redis -y

With npm, the -- separator is required — npm consumes flags before it instead of forwarding them to the CLI. pnpm create and yarn create forward flags without it.

Adapter values come from the chat/adapters catalog. The default interactive prompt lists official adapters. Pass --vendor to list vendor-official adapters instead. For automation and coding agents, pass official or vendor adapter slugs directly with --adapter. Community adapters are not scaffolded.

When the CLI detects a coding agent environment, it announces the detection and automatically runs in non-interactive mode. Pass at least one platform adapter with --adapter; the state adapter defaults to memory. If no project name is provided, the default name is my-bot. Pass --interactive to force prompts.

Vercel Connect

The Slack, Discord, GitHub, Linear, Notion, and Telegram adapters can use Vercel Connect for outbound credentials. Pass --connect, or choose Vercel Connect at the interactive auth-mode prompt:

npm create chat-sdk@latest -- my-bot --adapter slack --connect -y

The generated bot spreads the matching helper from @vercel/connect/chat into the adapter factory, adds @vercel/connect to dependencies, and lists each connector UID (such as SLACK_CONNECTOR) in .env.example. Native webhook verification secrets are retained for adapters such as Notion and Telegram.

Options

Usage: create-chat-sdk [options] [name]

Arguments:
  name                      name of the project

Options:
  -d, --description <text>  project description
  --adapter <values...>     platform or state adapters to include
  --vendor                  list vendor-official adapters in the interactive
                            prompt
  --connect                 authenticate Slack, Discord, GitHub, Linear,
                            Notion, and Telegram adapters with Vercel Connect
  --pm <manager>            package manager to use (npm, yarn, pnpm, bun)
  -y, --yes                 skip prompts and accept defaults
  --interactive             always prompt, even when a coding agent
                            environment is detected
  -f, --force               overwrite generated files in an existing directory
  -s, --skip-install        skip dependency installation
  --no-git                  skip git repository initialization
  -q, --quiet               suppress non-essential output
  -h, --help                display help for command

Color output follows the NO_COLOR standard — set NO_COLOR=1 to disable colors.

Generated project

The generated project is a minimal Next.js API app:

  • src/lib/bot.ts — generated Chat SDK bot configuration
  • src/app/api/webhooks/[platform]/route.ts — dynamic webhook route
  • src/app/api/chat/route.ts — generated only when the Web adapter is selected
  • .env.example — generated from selected adapter env specs
  • next.config.ts — generated server config and externals
  • package.json — generated adapter, peer, and extra dependencies
  • .chat-sdk.json — generated file ownership used by safe --force reruns

The template does not include pages, layouts, or a client UI.

Development

pnpm --filter create-chat-sdk build
pnpm --filter create-chat-sdk typecheck
pnpm --filter create-chat-sdk test

AI Coding Agents

If you use an AI coding agent such as OpenAI Codex, Claude Code, or Cursor, install the Chat SDK skill so it knows the SDK APIs, adapter patterns, and project conventions before writing code.

npx skills add vercel/chat

The skill references bundled documentation in node_modules/chat/docs, plus adapter guides and starter templates in the published package.

You can also install the Vercel Plugin for a broader agent toolkit — it includes the Chat SDK skill alongside specialist agents, agent slash commands, and more:

npx plugins add vercel/vercel-plugin

The plugin is optional; the skill alone is enough to build with Chat SDK.

For agent-readable documentation, see chat-sdk.dev/llms.txt (page index) or chat-sdk.dev/llms-full.txt (full text).
