The Slack adapter renders them as a `datepicker` and a `number_input`, the Teams adapter as `Input.Date` and `Input.Number`, and both submitted values arrive in `event.values` as strings. Teams submit values that arrive as JSON numbers are now stringified into `event.values` instead of being dropped. This fixes `Input.Number`, but applies to any numeric value a Teams dialog submits — a key that was previously absent from `event.values` will now be present as a string. ### Patch Changes - Updated dependencies [257a32d] - Updated dependencies [c5d86b1] - Updated dependencies [0153a39] - Updated dependencies [b547f45] - Updated dependencies [caa6325] - chat@4.36.0 - @chat-adapter/shared@4.36.0 ## @chat-adapter/teams@4.36.0 ### Minor Changes -0153a39: Add `DateInput` and `NumberInput` modal children.

The XChat crypto stack (`@xdevplatform/chat-xdk`, `@xdevplatform/xdk`, `juicebox-sdk`) is an optional peer dependency, so existing `@chat-adapter/x` users are unaffected. All cryptography is handled inside the adapter via `@xdevplatform/chat-xdk` (wasm) and all REST goes through the typed `@xdevplatform/xdk` client. Only a bot token and a Juicebox PIN are required: the bot's identity (user id and @handle) is resolved from `GET /2/users/me` at startup. - Encrypted send/receive in DMs and groups (webhook push + polling), signature verification on by default; undecryptable or unverified events are dropped - Webhook POSTs must carry a valid `x-twitter-webhooks-signature`, which X sends on every delivery. Set `consumerSecret` (or `X_CONSUMER_SECRET`) to receive webhooks, or `disableWebhookVerification` when an upstream layer already verifies them. Polling deployments are unaffected - Mention detection from structured mention entities, swipe-replies to the bot, and a plain-text `@handle` fallback; group replies sent as quoted replies - `openDM(userId)` starts (or reuses) an encrypted 1:1, running a full key exchange when needed so the bot can message first - Media both ways: inbound attachments with lazy download+decrypt, outbound encrypted uploads - Edit and delete of the bot's own messages; the first edit of a fresh message is age-gated by `editSafetyDelayMs` (default 5000ms) so receiving clients have stored the original - Reactions in and out, read receipts (`sendReadReceipts`, default on), typing keep-alive, configurable group welcome message - Cards degrade to text with tappable URL/mention entities plus a URL preview attachment - Requests carry a `chat-sdk-xchat/<version>` User-Agent product token so Chat SDK traffic is identifiable in X API request logs (a User-Agent set via `apiHeaders` takes precedence) - Registered in the `chat/adapters` catalog and the `create-chat-sdk` CLI scaffold, with a new optional `importPath` catalog field for adapters that ship on a subpath ### Patch Changes - Updated dependencies [257a32d] - Updated dependencies [c5d86b1] - Updated dependencies [0153a39] - Updated dependencies [b547f45] - Updated dependencies [caa6325] - chat@4.36.0 - @chat-adapter/shared@4.36.0 ## chat@4.36.0 ### Minor Changes -c5d86b1: confine built-in agent read tools to the conversation being handled, with an optional scope override -0153a39: Add `DateInput` and `NumberInput` modal children.

A message containing `jane@acme.com` no longer triggers a bot named `acme`, because the `@` in `detectMention` must not follow a word character. Real mentions are unaffected, including at the start of a message, after punctuation, and suffixed names such as GitHub's `mybot[bot]`. -caa6325: Add XChat support to `@chat-adapter/x`, shipped from the new `@chat-adapter/x/chat` subpath so it sits alongside the existing X adapter.

@chat-adapter/shared
npm package:
@chat-adapter/shared
Shared utilities for Chat SDK adapters. Provides common helpers used across adapter implementations.
Documentation: chat-sdk.dev/docs/contributing/building · Guides: vercel.com/kb/chat-sdk
Installation
pnpm add @chat-adapter/shared
Utilities
Adapter helpers
extractCard(message)- extract aCardElementfrom anAdapterPostableMessageextractFiles(message)- extractFileUpload[]from anAdapterPostableMessageextractPostableAttachments(message)- extractAttachment[]from anAdapterPostableMessage
Buffer conversion
toBuffer(input)- convert various inputs (Buffer, Blob, string, URL) to BuffertoBufferSync(input)- synchronous version of toBufferbufferToDataUri(buffer, mimeType)- convert a Buffer to a data URI string
Card conversion
cardToFallbackText(card)- render aCardElementas plain text for platforms that don't support cardscreateEmojiConverter(platform)- create a function that converts emoji placeholders to platform formatmapButtonStyle(style)- map generic button styles to platform-specific variantsrenderGfmTable(headers, rows)- render a GitHub Flavored Markdown tableescapeTableCell(text)- escape pipe characters in table cells
Token encryption
AES-256-GCM helpers for encrypting OAuth tokens at rest before writing them to a state adapter. Used by @chat-adapter/slack and @chat-adapter/linear; available to any adapter that persists credentials.
encryptToken(plaintext, key)- encrypt a string and return anEncryptedTokenDataenvelope (random 12-byte IV per call)decryptToken(data, key)- decrypt an envelope back to the original stringdecodeKey(encoded)- decode a hex-64 or base64-44 encoded 32-byte key; throws on wrong lengthisEncryptedTokenData(value)- type guard for distinguishing envelopes from legacy plaintext recordsEncryptedTokenData- the envelope type ({ data, iv, tag }, all base64)
Error classes
Standardized errors for adapter implementations:
AdapterError- base error classAdapterRateLimitError- platform rate limit (includesretryAfter)AuthenticationError- expired or invalid tokensNetworkError- connection failuresPermissionError- missing scopes or permissionsResourceNotFoundError- missing channel/thread/messageValidationError- invalid config or input
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).
