In `@docs/ai-chat/backend.mdx`:
- Around line 391-415: The example server actions currently trust raw chatId and
return all rows; update getChatMessages, getAllSessions, and deleteSession to
scope results to the authenticated user by using the caller's user id (from the
auth/session context) and filtering DB queries (replace db.chat.findUnique,
db.chatSession.findMany, db.chatSession.delete usages) with where: { id: chatId,
userId } or where: { userId } respectively; for deleteSession verify ownership
before deleting (return error or no-op if not owner), and for getAllSessions
only return sessions belonging to that user and avoid leaking other users'
publicAccessToken (either omit or mask tokens unless the requester owns them).
Ensure these functions take or derive the current user id and perform explicit
auth checks before DB operations.
In `@docs/ai-chat/features.mdx`:
- Around line 25-29: The example initializes userContext via chat.local with
fields name, plan, and messageCount but later reads userContext.get().userId,
causing a type mismatch; update the chat.local declaration (userContext) to
include userId in the type and initial value so the persisted object actually
contains userId, and mirror the same fix for the other occurrences referenced
(lines 39-43 and 125-134) where userId is later read so all examples are
consistent and will typecheck.
In `@docs/ai-chat/frontend.mdx`:
- Around line 71-126: The component is written as a page but expects a custom
prop chatId; update it to read route params or move logic into a client
component: either (A) change the page to export default async function Page({
params }) { const chatId = params.chatId; return <ChatClientWrapper
chatId={chatId} /> } where ChatClientWrapper is a client component that uses the
existing ChatPage/ChatClient logic, or (B) move ChatClient (and the
useEffect/load logic) into a new client component (e.g., ChatClient.tsx) and
have app/chat/[chatId]/page.tsx import that component and pass params.chatId to
it; adjust references to getChatMessages, getSession, getChatToken and
deleteSession to be called only inside client-side components (use client
directive) and ensure useTriggerChatTransport and useChat remain inside the
client component.
In `@docs/ai-chat/quick-start.mdx`:
- Line 13: The code fence language tags in docs/ai-chat/quick-start.mdx use
`ts`/`tsx` (e.g. the snippet starting with "```ts trigger/chat.ts") but our docs
convention requires full `typescript` tags; update each fenced code block
(including the ones referenced at lines 36 and 50) to use `typescript` instead
of `ts` or `tsx` so the snippets follow the project's language-tagging
guideline.

Learning: In the triggerdotdev/trigger.dev repository, docs PRs are often written as companions to implementation PRs (e.g., PR `#3200` documents features being added in PR `#3196`). When reviewing docs PRs, the documented features may exist in a companion/companion PR branch rather than main. Always check companion PRs referenced in the PR description before flagging missing implementations.

Timestamp: 2026-02-25T17:28:20.456Z
Learning: In the Trigger.dev codebase, the `publicAccessToken` returned by the SDK's `wait.createToken()` method is not part of the HTTP response body from `POST /api/v1/waitpoints/tokens`. The server returns only `{ id, isCached, url }`. The SDK's `prepareData` hook generates the JWT client-side from the `x-trigger-jwt-claims` response header after the HTTP call completes. The OpenAPI spec correctly documents only the HTTP response body, not SDK transformations.

Scope these example server actions to the authenticated user.
getChatMessages, getAllSessions, and deleteSession trust raw chatIds or return all rows. In a multi-user app, copying this verbatim would let one client read or remove another user's chat state, and getAllSessions() would expose other users' publicAccessTokens.

Persist userId if the later example reads it back.
This local is initialized with name, plan, and messageCount, but the persistence example later calls userContext.get().userId. As written, the snippet won't typecheck and suggests data is available that was never stored.

🧩 Analysis chain
🌐 Web query:
In Next.js App Router, what props does a default export in app/page.tsxreceive, and how should a page component access a dynamicchatId?
💡 Result:
In the App Router, the default export in app/page.tsx (a Page component) does not receive arbitrary “props” like pageProps. It only receives route-derived props:
searchParams(query string params) — and in Next.js 15, it’s passed as a Promise. [1], [2]params(dynamic route segments) — only if the route has dynamic segments; in Next.js 15, it’s also a Promise. [1], [3]
To access a dynamic chatId, make the route dynamic (e.g. app/chat/[chatId]/page.tsx) and read it from params, e.g.:
// app/chat/[chatId]/page.tsx
export default async function Page({
params,
}: {
params: Promise<{ chatId: string }>;
}) {
const { chatId } = await params;
// use chatId...
}This is the App Router pattern for dynamic segments (params) rather than expecting chatId as a normal prop. [1], [3]
Sources: [1] https://nextjs.org/docs/messages/next-prerender-sync-params, [2] https://nextjs.org/learn/dashboard-app/adding-search-and-pagination, [3] https://nextjs.org/docs/app/api-reference/file-conventions/dynamic-routes
Show a runnable app/page.tsx example that reads chatId from dynamic route params.
This snippet is labeled app/page.tsx but expects chatId as a custom prop. In App Router, page components receive only params (for dynamic route segments) and searchParams (from query strings), not arbitrary props. Move this to a non-page client component file (e.g., components/ChatClient.tsx), or rewrite it as an actual page that reads params.chatId from a route like app/chat/[chatId]/page.tsx.

Use typescript fence tags for the snippets.
These blocks are tagged ts/tsx. The docs conventions here require typescript, and the same cleanup likely applies across the other new AI Chat pages too.

module that exports it and import { z } from "zod") so schemaTask(...) and
z.object(...) resolve; specifically, add an import for schemaTask (to match your
SDK export, e.g., from "@trigger.dev/sdk" or the tasks submodule) and import z
from "zod" alongside the existing ai and chat imports.
- Around line 376-382: The code uses the React hook useEffect but doesn't import
it; add an import for useEffect from React (so the file imports useEffect
alongside any existing React imports) to ensure useEffect in the useEffect(() =>
{ transport.preload(chatId, { idleTimeoutInSeconds: 60 }); }, [chatId]); block
resolves; verify other symbols like useChat, transport, chatId and sendMessage
remain unchanged.

Nitpick comments:
In `@docs/ai-chat/features.mdx`:
- Around line 159-170: The example for myChat uses streamText, openai, and db
but omits their imports; update the snippet so it is self-contained by adding
import statements for streamText, the openai helper, and the database client
used (the symbols streamText, openai, and db) at the top of the file or example
block, ensuring the imports match the project's export names and runtime (e.g.,
import { streamText } from "...", import { openai } from "...", import { db }
from "...") so chat.task and myChat can run without unresolved symbol errors.

Learning: In the triggerdotdev/trigger.dev repository, docs PRs are often written as companions to implementation PRs (e.g., PR `#3200` documents features being added in PR `#3196`). When reviewing docs PRs, the documented features may exist in a companion/companion PR branch rather than main. Always check companion PRs referenced in the PR description before flagging missing implementations.

124-135: Type mismatch:userIdnot declared inuserContext.The example accesses
userContext.get().userIdat line 128, but theuserContexttype declared earlier (lines 25-29) doesn't includeuserId. Either adduserIdto the type declaration and initialization, or use a different property that exists (like deriving fromclientData).
17-56: LGTM!The example demonstrates the full lifecycle of
chat.localwith consistent types and usage.
81-114: LGTM!The subtask example clearly demonstrates auto-hydration of locals with consistent typing.
223-284: LGTM!The subtask streaming example effectively demonstrates the

Missing imports for schemaTask and z.
The example uses schemaTask and z without importing them, which would cause compilation errors.
Proposed fix
import { ai, chat } from "@trigger.dev/sdk/ai";
+import { schemaTask } from "@trigger.dev/sdk";
+import { z } from "zod";
import type { myChat } from "./chat";As per coding guidelines, "Code examples must be complete and runnable where possible".

🧩 Analysis chain
🌐 Web query:
AI SDK useChat hook return values append handleSubmit
💡 Result:
The useChat hook from Vercel AI SDK (current version as of 2026 is 5+) returns an object with several properties and methods for managing chat state and interactions. Key returns include: - messages: UIMessage[] - Current array of chat messages. - status: 'submitted' | 'streaming' | 'ready' | 'error' - Current chat status. - error?: Error - Error if one occurred. - id: string - Unique chat identifier. - sendMessage: (message?: { text: string; ... }, options?: ChatRequestOptions) => Promise - Sends a new message (replaces older 'append'). - handleSubmit is not a direct return of useChat in current versions; it was likely a custom form handler in older examples using the old input/handleInputChange/handleSubmit pattern. Now, manage input with useState and call sendMessage on form submit. - Other methods: regenerate, stop, setMessages, addToolOutput, clearError, resumeStream. In older versions (pre-5.0, e.g. ai/react), useChat returned additional items like input, handleInputChange, handleSubmit (for form submission), and append (for programmatic message addition). These were removed in 5.0 with the transport architecture change - input state is no longer managed internally; use sendMessage instead. See migration guide for details. Example usage (current): const { messages, sendMessage, status } = useChat({ transport: new DefaultChatTransport({ api: '?url=https%3A%2F%2Fgithub.com%2Fapi%2Fchat' }) }); const [input, setInput] = useState(''); const handleSubmit = (e) => { e.preventDefault; if (!input.trim) return; sendMessage({ text: input }); setInput(''); }; For programmatic append (older style): In v4, use append({ role: 'user', content: 'text' }). In v5+, use setMessages(prev => [...prev, newMessage]) for local updates, or sendMessage.

Import useEffect from React.
The useEffect hook is missing its import statement from React. The sendMessage API is correct for current Vercel AI SDK versions.
