Implement True Query Concurrency with Multi-Threaded Chat UI #453
Conversation
…UI. This update introduces a major architectural change to support concurrent queries through a new tabbed chat interface. Key changes include: - **Multi-Threaded UI**: I replaced the single-threaded chat with a `ChatThreadManager` supporting multiple concurrent conversation tabs. - **Non-Blocking Backend**: I refactored the core request server action to return the UI stream immediately while processing agents in the background. - **Contextual Isolation**: I introduced `threadId` across `AIState`, `AIMessage`, and UI components to ensure that concurrent chats maintain independent context. - **Thread-Aware Persistence**: I updated `onSetAIState` to partition the global AI state by `threadId` and save each session as a distinct chat in the database. - **Map State Synchronization**: I coordinated the shared map component to save and restore drawing context (features, camera) per chat thread. - **Build Compliance**: I reorganized server actions and AI provider definitions to comply with Next.js 15 Server Action constraints. - **Enhanced User Experience**: I added a "+" button to the chat input and mobile icons bar for seamless thread creation.

🤖 Fix all issues with AI agents
In `@app/actions.tsx`:
- Around line 329-356: In processEvents the inquire branch returns early so the
shared cleanup in the finally block can be bypassed; consolidate
stream/finalization by extracting an idempotent cleanup helper (e.g.,
finalizeStreams) that calls uiStream.done(), isGenerating.done(), and
isCollapsed.done(false) (and sets a local "finalized" flag) and then replace the
inline calls in the inquire branch with a call to finalizeStreams and keep the
finally block calling finalizeStreams as well so cleanup runs consistently
without double-calling; reference processEvents, uiStream.done,
isGenerating.done, isCollapsed.done, and the finally block.
- Around line 387-403: The code is using Array.prototype.map for
side-effect-only iteration over toolOutputs and discards its return; change the
map call to forEach to make intent clear and avoid unused allocations: locate
the block where toolOutputs.map(...) is called (the update that calls
aiState.update and appends messages using groupeId, role 'tool', content
JSON.stringify(output.result), name output.toolName, type 'tool') and replace
the map with toolOutputs.forEach(...) keeping the body and aiState.update logic
identical.
- Around line 465-470: In processEvents' catch block, send a user-facing error
message into the UI stream before closing so users see failure feedback; update
the catch to append a concise error message (including a short sanitized error
detail) to uiStream (e.g., using the same append/write/send method the stream
uses), then ensure isGenerating.done(false) and uiStream.done() are still called
in finally; reference processEvents, the catch block, uiStream
(append/write/send), and isGenerating.done to locate where to add the append.
- Around line 430-464: When errorOccurred is true the function never calls
aiState.done(), leaving the AI state in an intermediate state; ensure you always
finalize the state by invoking aiState.done() even on errors — for example, call
aiState.done(aiState.get()) or aiState.done({ ...aiState.get(), /* preserve or
mark error */ }) in the error branch so the run that updated state via
aiState.update() is properly completed; locate the surrounding logic that
references errorOccurred, aiState.get(), and aiState.done() (and symbols like
groupeId/messages) and add the finalizing aiState.done() call in the error path,
optionally including an error marker in the object you pass to done().
In `@components/chat-panel.tsx`:
- Around line 208-222: The wrapper <div> is always rendered even when the inner
Button is not (e.g., when isMobile is true or messages.length === 0); change the
JSX so the wrapper div is only rendered when the Button would be visible by
moving the condition (!isMobile && messages.length > 0) to wrap the outer div
instead of just the Button—locate the block using the isMobile and messages
symbols and the handleClear/Plus/Button elements and render the entire div
conditionally.
In `@tests/chat.spec.ts`:
- Around line 7-13: The catch block currently hides the loading overlay via
page.addStyleTag when page.waitForSelector('[data-testid="loading-overlay"]', {
state: 'hidden', timeout: 5000 }) times out, which may mask real loading
failures; change this to either (A) increase the timeout and re-run
waitForSelector to allow longer loads, and if it still times out explicitly fail
the test by throwing an Error with a descriptive message (remove the
CSS-injection workaround), or (B) if the CSS-injection is truly required for CI
stability, replace the silent workaround with a clear comment explaining the
root cause and intent and log a warning before injecting; update references in
this block around page.waitForSelector and page.addStyleTag accordingly.

🧹 Nitpick | 🔵 Trivial
Use forEach instead of map for side-effect-only iteration.
The return value of map() is discarded. Since this loop only performs side effects (aiState.update), forEach is more semantically appropriate.

AI state is not finalized when errorOccurred is true.
When errorOccurred is true (line 430), aiState.done() is never called—the state remains in an intermediate state from prior aiState.update() calls. This could lead to inconsistent state persistence or issues in subsequent interactions.
Consider calling aiState.done() with the current state even when an error occurs:
🐛 Proposed fix
if (!errorOccurred) {
const relatedQueries = await querySuggestor(uiStream, messages)
// ... existing code ...
aiState.done({
// ... existing state updates ...

Consider providing user-facing error feedback.
When an error occurs in processEvents, it's logged to the console but the user receives no indication of failure. The UI stream is closed normally in finally, potentially leaving the user with an incomplete or confusing response.
Consider appending an error message to the UI stream before closing it:

The wrapper <div> at line 208 is always rendered even when its child button is not visible (e.g., on mobile or when there are no messages). While this doesn't cause functional issues, it adds an unnecessary empty DOM node.

CSS injection workaround may mask legitimate loading failures.
Force-hiding the loading overlay via CSS injection when it doesn't disappear within 5 seconds could hide actual bugs where the loading state never resolves. Consider:
- Investigating why the overlay might not disappear naturally
- Increasing the timeout if the loading is legitimately slow
- Failing the test explicitly if loading takes too long, rather than working around it
If this workaround is intentional for CI stability, adding a comment explaining the root cause would help future maintainers.

There was a problem hiding this comment.
The biggest correctness risk is potential double-finalization of uiStream/isGenerating due to the new finally plus early-return branch cleanup in processEvents(). The new fire-and-forget persistence in onSetAIState can silently drop chat saves in serverless runtimes, which conflicts with the PR’s promise of thread-aware persistence. There are smaller maintainability concerns around using .map() for side effects and potentially racy repeated aiState.update() calls in a concurrent chat architecture. The Playwright test’s forced overlay hiding may mask real readiness/loading regressions and should be replaced with a deterministic readiness condition.
Additional notes (1)
- Maintainability |
app/actions.tsx:588-594
The non-blockingsaveChat(chat, actualUserId).catch(...)makes persistence best-effort. If the serverless runtime/edge worker is suspended right after returning the response, the save can be dropped, leading to silently lost chat history.
Given the PR’s stated goal is concurrency/non-blocking UI, this is understandable, but you still need some reliability strategy (queue, revalidate step, or explicit await in critical paths).

There was a problem hiding this comment.
processEvents() now always calls uiStream.done() in finally, even when the flow returns early for the 'inquire' branch (which also calls uiStream.done() before returning). Calling .done() twice is a correctness risk (depending on the streamable implementation it can throw, log noisy errors, or drop subsequent UI updates).
This is especially likely here because the early-return path is common and intentionally calls uiStream.done() immediately.
Suggestion
Avoid double-finalization by not calling uiStream.done()/isGenerating.done() inside branch bodies and letting finally own cleanup, or track a flag.
Example:
async function processEvents() {
try {
// ...
if (action.object.next === 'inquire') {
const inquiry = await inquire(uiStream, messages)
isCollapsed.done(false)
aiState.done({
...aiState.get(),
messages: [
...aiState.get().messages,
{ id: nanoid(), role: 'assistant', content: `inquiry: ${inquiry?.question}` }
]
})
return
}
// ... rest of flow
} catch (error) {
console.error('Error in processEvents:', error)
} finally {
isGenerating.done(false)
uiStream.done()
}
}If you prefer to keep branch-local .done(), guard in finally:
let finished = false
// set finished = true when done
if (!finished) uiStream.done()Reply with "@CharlieHelps yes please" if you'd like me to add a commit with this suggestion.

Using .map() for side effects (toolOutputs.map(...)) is misleading and makes it easy to assume a returned array is used. This is a readability/maintainability issue, and in a concurrency-focused change it’s important to keep async flows clear.
Also, repeated aiState.update({ ...aiState.get(), messages: [...] }) inside a loop can race with other concurrent updates (even if TypeScript passes). In a multi-thread/concurrent UI, consider batching tool messages into a single update to reduce the chance of interleaving updates unexpectedly.
Suggestion
Replace .map() with for...of and batch updates:
if (toolOutputs.length > 0) {
const toolMessages = toolOutputs.map(output => ({
id: groupeId,
role: 'tool',
content: JSON.stringify(output.result),
name: output.toolName,
type: 'tool'
}))
aiState.update({
...aiState.get(),
messages: [...aiState.get().messages, ...toolMessages]
})

processEvents() now catches errors and always finalizes isGenerating/uiStream, which is good, but the catch block only logs and never records an error message into the UI or AI state. In a concurrent/multi-thread chat UI, this can leave a thread showing a spinner/empty response area with no explanation (especially since you now render the response section immediately). Users need an explicit failure response in the thread, and the thread’s state should be finalized deterministically (e.g., append an assistant error message) so persistence and replay are consistent.
Suggestion
Add a visible fallback response on error and ensure AI state captures it. For example, in catch, append an assistant message like "Sorry—something went wrong. Please try again." (or include a sanitized error code) and update the uiStream with a Section/BotMessage if streamText is still pending. Also consider marking aiState.done(...) with an error-type message so the conversation thread persists a terminal state.

The Playwright workaround force-hides the loading overlay after 5s. This can make tests pass while the app is still legitimately loading (masking regressions), and it can introduce flakiness if the overlay is used as a true gate for readiness.
Since you now control the overlay test id, prefer waiting on a concrete readiness signal (e.g., chat input enabled, first render complete, network idle) rather than forcibly disabling UI elements.
Suggestion
Prefer waiting on app readiness instead of forcing CSS overrides. For example:
await page.goto('/')
await page.waitForSelector('[data-testid="chat-input"]')
await expect(page.locator('[data-testid="chat-input"]')).toBeEnabled()
await expect(page.locator('[data-testid="loading-overlay"]')).toHaveCount(0)If the overlay sometimes lingers due to animation, consider making the app remove it deterministically when initialization completes, and test that behavior.

…ti-threaded chat UI. This update introduces a major architectural change to support concurrent queries through a new multi-threaded (tabbed) chat interface. Key changes include: - **Multi-Threaded UI**: Replaced the single-threaded chat with a `ChatThreadManager` supporting multiple concurrent conversation tabs. - **Non-Blocking Backend**: Refactored the message-processing server action to return the UI stream immediately while handling agent tasks in the background. - **Contextual Isolation**: Introduced `threadId` across `AIState`, `AIMessage`, and UI components to ensure that concurrent chats maintain independent context. - **Thread-Aware Persistence**: Updated the state management logic to partition the global AI state by `threadId` and save each session as a distinct chat in the database. - **Map State Synchronization**: Coordinated the shared map component to save and restore drawing context (features, camera) per chat thread. - **Build Compliance**: Reorganized server actions and AI provider definitions to comply with Next.js 15 Server Action constraints. - **Enhanced User Experience**: Added a "+" button to the chat input and mobile icons bar for seamless thread creation. - **Stability**: Fixed TypeScript errors and verified successful build and linting.

🤖 Fix all issues with AI agents
In `@app/chat-actions.tsx`:
- Line 91: There are two hardcoded 500ms delays implemented with "await new
Promise(resolve => setTimeout(resolve, 500))" (one at the shown location and
another around the same pattern later) that look like legacy stream sync
workarounds; either remove them to avoid added latency or make their purpose
explicit and configurable: replace the raw literal with a named constant (e.g.,
STREAM_SYNC_DELAY_MS) and add a short comment explaining why the delay is
required (what race or stream behavior it mitigates), or remove both occurrences
if no longer necessary and run tests to verify no regression in
streaming/synchronization behavior. Ensure you update both occurrences of the
exact promise/setTimeout expression so behavior stays consistent.
- Around line 25-29: Replace the unsafe any in getMutableAIState<any>() with the
concrete AI state type exported by your AI provider: import the proper type
(e.g., AIState or MutableAIState) from the AI provider module and use it as the
generic parameter to getMutableAIState (so aiState is strongly typed). Update
the import list and the call to getMutableAIState<YourAIStateType>() and ensure
downstream usage of aiState matches the new type.
In `@components/chat-panel.tsx`:
- Around line 119-121: The form submission currently appends threadId manually
after creating FormData from the form (new FormData(e.currentTarget)), causing
duplicate threadId entries; remove the conditional formData.append('threadId',
threadId) block so the hidden input already on the form supplies the value, or
alternatively remove the hidden input and keep the append—update the submit
handler where new FormData(e.currentTarget) and formData.append('threadId',
threadId) are used to ensure threadId is only provided once.
In `@components/chat-thread-manager.tsx`:
- Around line 86-103: The thread tabs are non-semantic divs with onClick
handlers (inside threads.map) so keyboard users can't switch threads; replace
each clickable thread container with a semantic interactive element (e.g., a
button) or add proper keyboard handlers to call switchThread(thread.id) on
Enter/Space and include focus styles and aria-selected/role="tab" attributes;
also ensure the Add Thread control (addThread) is a real button (it already uses
Button—verify props) and keep activeThreadId and initialThread logic for
labeling and styling unchanged.
- Around line 128-156: The desktop thread tabs are rendered as clickable divs
(inside threads.map) and lack keyboard accessibility; replace the outer div used
for each tab with a semantic button (or add role="tab", tabIndex={0} and an
onKeyDown handler) so that keyboard users can activate switchThread(thread.id)
via Enter/Space, preserve the existing active styling tied to activeThreadId and
initialThread, ensure the X removeThread(thread.id) handler still calls
e.stopPropagation() to avoid triggering the tab action, and update the addThread
Button usage if needed; target the component rendering the tabs (the threads.map
block and its onClick handler, plus the X icon onClick) to implement these
changes.
In `@components/followup-panel.tsx`:
- Around line 34-38: The current setMessages call can overwrite a
server-provided threadId with undefined; when building the response message
(responseMessage) ensure you preserve any server-supplied threadId by explicitly
setting threadId: responseMessage.threadId ?? threadId (or similar) when
spreading/creating the message object in the setMessages update so that a
missing prop doesn't strip the association; update the setMessages callback that
references responseMessage, userMessage, and threadId to apply this fallback.
In `@components/header-search-button.tsx`:
- Around line 93-99: The code currently forces threadId to the local prop when
appending the server response (setMessages(... { ...responseMessage as any,
threadId })), which overwrites a server-provided responseMessage.threadId with
undefined; change the merged object so it preserves the server-sent id when
present by using the server value first, e.g. setMessages(currentMessages =>
[...currentMessages, { ...responseMessage as any, threadId: (responseMessage as
any).threadId ?? threadId }]), locating this change around the actions.submit
call and the setMessages usage.
In `@components/search-related.tsx`:
- Around line 52-61: The code currently unconditionally spreads responseMessage
and then sets threadId from the outer variable, which can overwrite a
server-provided responseMessage.threadId with undefined; update the setMessages
call that adds responseMessage (and the surrounding logic after
submit(formData)) to only assign threadId when the local prop threadId is
defined (e.g., keep responseMessage.threadId if present, otherwise fall back to
threadId), or conditionally add the threadId property—refer to submit,
responseMessage, setMessages, threadId, and userMessage to locate and change the
merge so server-supplied threadId is preserved.
In `@lib/chat/ui-mapper.tsx`:
- Around line 183-184: In the switch handling inside ui-mapper (the 'tool'
case), there's an unreachable "break" after branches that always return; remove
that redundant break to clean up the control flow. Locate the 'tool' case in the
function/component that renders mapper output (search for the 'tool' case in
lib/chat/ui-mapper.tsx) and delete the trailing break statement so the case only
contains the existing return paths.
- Around line 37-68: The switch cases for role/type leak variables like
messageContent because case clauses lack block scoping; wrap each case body in
braces so variables declared in one case (e.g., messageContent in the 'user' ->
'input'/'input_related' branch) are scoped locally, and similarly scope the
'inquiry' branch that returns the CopilotDisplay component; update the switch
handling around role/type in ui-mapper.tsx (referencing messageContent,
UserMessage, CopilotDisplay, id, threadId, component) to use { ... } blocks for
each case to prevent cross-case scope leakage.
- Around line 69-121: The assistant branch uses JSON.parse without error
handling and declares consts across switch cases; for the 'related' and
'resolution_search_result' cases (symbols: relatedQueries, analysisResult,
geoJson, SearchRelated, GeoJsonLayer, createStreamableValue) wrap each case body
in its own block and surround JSON.parse calls with try/catch to prevent a crash
on malformed content—on parse error return a safe fallback component (e.g., an
error/empty Section or null) and optionally log the error; ensure all const
declarations remain inside the block scope so they don't collide with other
cases.

legacy stream sync workarounds; either remove them to avoid added latency or
make their purpose explicit and configurable: replace the raw literal with a
named constant (e.g., STREAM_SYNC_DELAY_MS) and add a short comment explaining
why the delay is required (what race or stream behavior it mitigates), or remove
both occurrences if no longer necessary and run tests to verify no regression in
streaming/synchronization behavior. Ensure you update both occurrences of the
exact promise/setTimeout expression so behavior stays consistent.

🧹 Nitpick | 🔵 Trivial
Redundant threadId in form submission.
The threadId is included both as a hidden input field (line 187) and explicitly appended to FormData (lines 119-121). The hidden input will already be included in FormData via new FormData(e.currentTarget), so the conditional append is unnecessary and could result in duplicate values.
♻️ Proposed fix - remove redundant append
const formData = new FormData(e.currentTarget)
- if (threadId) {
- formData.append('threadId', threadId)
- }
if (selectedFile) {
formData.append('file', selectedFile)
}Alternatively, if the hidden input should be removed:
- <input type="hidden" name="threadId" value={threadId} />Also applies to: 187-187

I've fixed the calendar UI rendering. It was being overlapped by the header in the new multi-threaded layout. I've adjusted the desktop padding and layout to ensure the calendar is fully visible when toggled. |
I've fixed the issue where no response was showing for input. This was caused by the asynchronous background processing start-up pattern which required a UI stream update before returning the action result. I've also strengthened the AI state binding to ensure background updates are correctly propagated to the client. |
- Fixed calendar UI rendering by adjusting desktop layout padding and ensuring it's not overlapped by the header. - Fixed missing input response by ensuring the UI stream is updated before returning the server action. - Strengthened AI state binding in background processing for reliable client updates. - Refined thread ID propagation through components.

per-item mapping so threads.map only returns the single thread chip element, and
render the surrounding container (including the Button that calls addThread and

- Around line 71-73: The div rendered inside threads.map uses the "contents" CSS
class which sets display: contents and is immediately overridden by the

Remove the mimeType property from the image content object.
The mimeType property is not supported by the AI SDK's CoreMessage['content'] type. Image content should only contain type: 'image' and image: string. The MIME type is already embedded in the data URL format (data:image/png;base64,...), making this property redundant. Other instances in the codebase (e.g., components/user-message.tsx, components/chat-panel.tsx) correctly omit this property. Change line 55 to:

Thread switcher rendered redundantly inside per-thread loop.
The thread switcher (lines 86-103) is inside the threads.map loop starting at line 71, causing it to be rendered once per thread. Since only the active thread's container is visible, users see one switcher, but the DOM contains N copies. Consider moving the thread switcher outside the per-thread loop for cleaner structure and reduced DOM size.

Here are the key updates: - I transitioned the query server action to be non-blocking, allowing it to return immediately while processing AI responses in the background. - I introduced a `ChatThreadManager` to manage multiple independent chat sessions and tabs. - I isolated the `AIState` and persistence by partitioning them with a `threadId`. - I improved streaming reliability by initializing `StreamableValue` with empty strings and ensuring that all streams are properly concluded. - I integrated the `CalendarNotepad` as a toggleable overlay within the `ChatView`. - I refactored common chat logic, such as `getChatTitle`, into utility functions.

In `@app/chat-actions.tsx`:
- Around line 331-333: Seed the UI stream before launching the async event loop
so the initial render isn’t blank: after creating streamText with
createStreamableValue<string>('') and before calling processEvents(), call
uiStream.update() (or uiStream.append()) to bind streamText into uiStream so
submit() can return a non-empty uiStream.value immediately; update the general
flow where submit() returns uiStream.value to ensure the stream is initialized
prior to researcher() appending deltas (see streamText, createStreamableValue,
processEvents, submit, uiStream, researcher).
In `@components/chat-view.tsx`:
- Line 33: Replace the unsafe any cast used in the filter (const messages =
allMessages.filter((m: any) => m.threadId === id)) by adding a proper typed
message interface (e.g., ThreadedMessage or extend UIState message type to
include threadId) and use that type in the filter (e.g., allMessages.filter((m:
ThreadedMessage) => m.threadId === id)); update or augment the UIState/message
type declaration so threadId is defined on messages and ensure any places that
construct messages conform to the new type.
- Around line 69-74: The current effect flips isSubmitting to false immediately
after calling chatPanelRef.current?.submitForm(), which loses loading state if
submitForm is asynchronous; change this to await the submission promise from
chatPanelRef.current.submitForm() (or update ChatPanelRef.submitForm to return a
Promise) and only call setIsSubmitting(false) in a finally block so loading
state reflects the real lifecycle and errors can be handled (use try/catch
around await chatPanelRef.current.submitForm() and setIsSubmitting(false) in
finally).
- Around line 45-67: Replace the loose any casts in this useEffect by
introducing a proper AI message type (e.g., interface AIMessage { role: string;
threadId: string; content: unknown }) and ensure aiState.messages is typed as
AIMessage[]; update the filter/ find to use AIMessage instead of any
(referencing aiState.messages and drawingContextMessage) and add a type guard
before JSON.parse that checks typeof drawingContextMessage.content === 'string'
(and handle non-string content gracefully) so setMapData only consumes parsed
objects with drawnFeatures/cameraState.
- Around line 85-92: The effect on useEffect that calls updateDrawingContext on
every change to mapData.drawnFeatures/mapData.cameraState should be debounced
and wrapped with error handling: implement a debounce (via a local timer ref or
existing useDebounce hook) inside the useEffect tied to id, isActive,
mapData.drawnFeatures and mapData.cameraState so updates only fire after a short
pause, cancel the timer on cleanup/unmount, and await updateDrawingContext
inside a try/catch to log or surface errors instead of silently ignoring them;
reference the existing useEffect, updateDrawingContext, isActive, id,
mapData.drawnFeatures and mapData.cameraState when making the changes.
- Around line 41-43: The effect that syncs showEmptyScreen to messages is
unnecessary because showEmptyScreen is derived directly from messages.length;
remove the useEffect and the showEmptyScreen state, and instead compute a
derived value (e.g., const showEmptyScreen = messages.length === 0) where the
state is used; if the state was kept for animation timing, leave a comment and
preserve the effect, otherwise replace all references to showEmptyScreen with
the derived constant in the ChatView component (look for useEffect,
setShowEmptyScreen, and the showEmptyScreen state declaration).
- Around line 94-97: The calendar currently renders alongside the chat in
chat-view.tsx because isCalendarOpen is used with &&; change the rendering to a
ternary so CalendarNotepad replaces the chat UI when open. Replace the existing
line that renders "{isCalendarOpen && <CalendarNotepad chatId={id} />}" and the
subsequent <ChatPanel ... /> with a conditional expression using isCalendarOpen
? <CalendarNotepad chatId={id} /> : <ChatPanel ... /> (preserving all ChatPanel
props like messages, input, setInput, onSuggestionsChange, etc.) so behavior
matches chat.tsx.
In `@components/header.tsx`:
- Around line 69-71: The calendar toggle button is icon-only and currently
relies on title which isn't reliably announced; update the Button that calls
toggleCalendar (the one with data-testid "calendar-toggle-mobile" and child
CalendarDays) to include an explicit accessible label (e.g., add
aria-label="Open calendar" or use a visually hidden label) and mirror the same
change for the desktop toggle Button to keep behavior consistent across
breakpoints; ensure the aria-label text matches any desktop tooltip/title for
clarity.
In `@lib/utils/index.ts`:
- Around line 21-44: The getChatTitle function can throw if parsedContent.input

parsedContent.input before calling substring (e.g., typeof parsedContent.input
=== 'string') and only call substring on strings, otherwise coerce to a string
or use a safe fallback like 'Untitled Chat' (also apply the same guard where
firstMessageContent is used for substring). Reference getChatTitle,
parsedContent.input, firstMessageContent and ensure any substring calls are
protected by a string-type check or safe conversion.

Initialize the UI stream before returning in the general flow to avoid a blank initial render.
submit() returns uiStream.value immediately in the general flow (line 478), but uiStream remains empty at that moment. Content is only added asynchronously when researcher() calls uiStream.append() on its first text-delta (lib/agents/researcher.tsx:119–123), which may create a brief flash of empty UI. Seed the stream with a placeholder bound to streamText before launching processEvents().
Note: The resolution_search flow already handles this correctly by calling uiStream.update() before the return statement (lines 43–46).

Consider adding proper type definition for threaded messages.
The any cast weakens type safety. If the UIState type doesn't include threadId, consider extending or augmenting the type definition to properly type threaded messages.

🧹 Nitpick | 🔵 Trivial
Consider using derived state instead of effect.
showEmptyScreen is directly derived from messages.length. Using an effect to sync state can cause an extra render. Unless there's a specific reason for the indirection (e.g., animation timing), a direct derivation is cleaner.

🧹 Nitpick | 🔵 Trivial
Robust error handling, but multiple any casts reduce type safety.
The try/catch for JSON parsing is good. However, lines 49 and 51 use any casts. Consider defining a proper type for AI messages that includes role and threadId to improve maintainability.
Additionally, the check at line 54 assumes content is always a string. A type guard would be safer:
💡 Suggested type guard
if (drawingContextMessage) {
try {
+ if (typeof drawingContextMessage.content !== 'string') {
+ console.warn('Drawing context message content is not a string');

drawnFeatures/cameraState.

Potential timing issue with async form submission.
Setting isSubmitting to false immediately after calling submitForm() may not reflect actual submission state if the form submission is asynchronous. If the UI needs to reflect loading state during submission, consider using a callback or promise from submitForm().
💡 Alternative approach
useEffect(() => {
if (isSubmitting) {
- chatPanelRef.current?.submitForm()
- setIsSubmitting(false)
+ chatPanelRef.current?.submitForm().finally(() => {

Missing debounce and error handling for drawing context persistence.

Fix calendar rendering inconsistency in chat-view.tsx
The calendar rendering behavior differs between chat-view.tsx and chat.tsx. In chat.tsx (lines 125–173), CalendarNotepad replaces the chat UI entirely using a ternary conditional. However, in chat-view.tsx (line 96), CalendarNotepad renders alongside ChatPanel using an AND operator, making both visible simultaneously. Update chat-view.tsx to use a ternary conditional to replace chat content when the calendar is open, matching the behavior in chat.tsx:
{isCalendarOpen ? (
<CalendarNotepad chatId={id} />
) : (
<ChatPanel
messages={messages}
input={input}
setInput={setInput}
onSuggestionsChange={setSuggestions}
// ... other props
/>
)}🤖 Prompt for AI Agents
In `@components/chat-view.tsx` around lines 94 - 97, The calendar currently
renders alongside the chat in chat-view.tsx because isCalendarOpen is used with
&&; change the rendering to a ternary so CalendarNotepad replaces the chat UI

<CalendarNotepad chatId={id} />}" and the subsequent <ChatPanel ... /> with a
conditional expression using isCalendarOpen ? <CalendarNotepad chatId={id} /> :
<ChatPanel ... /> (preserving all ChatPanel props like messages, input,
setInput, onSuggestionsChange, etc.) so behavior matches chat.tsx.

User description
Implemented true query concurrency by introducing a multi-threaded chat interface. The system now supports multiple independent conversation threads within a single session, each with its own isolated context and map state. The backend submission logic has been updated to be non-blocking, allowing users to interact with other threads while AI processing occurs in the background. State persistence has been refactored to save each thread as a separate chat record in the database.
