Documentation and integrations
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR adds new typed headless UI adapters, but the current implementation still has core rendering and interaction failures across supported frameworks, including runtime-invalid component handling, missing or detached tool approvals and results, and typing contracts that permit invalid usage. These issues can break valid applications, so the PR is not merge-ready until the correctness problems are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@docs/migration/create-ui.md`:
- Around line 30-37: Update the `@tanstack/ai-svelte-ui` entry in the Minimum
versions list from 0.1.0 to 0.2.0, leaving the other package versions and
migration notes unchanged.
In `@docs/ui/react.md`:
- Line 31: Update the model identifier passed to openaiText in both
docs/ui/react.md (line 31) and docs/ui/solid.md (line 15) from gpt-5.2 to
gpt-5.6, leaving the surrounding guide examples unchanged.
In `@docs/ui/svelte.md`:
- Around line 13-15: Keep the server and client examples paired in both
framework guides: update docs/ui/svelte.md lines 13-15 and docs/ui/vue.md lines
13-15 to include the matching server endpoint snippets for the referenced chat
route and model, or explicitly remove the server-specific text and links so each
page is clearly client-only.
In `@docs/ui/vue.md`:
- Around line 40-42: Update the layout component in the defineComponents example
to render the interrupts slot alongside messages, and render the input slot when
an input component is registered; alternatively, revise the surrounding prose so
it no longer claims the registered interrupt fallback is rendered. Preserve the
existing message rendering and use the visible layout component symbol as the
change point.
In `@examples/ts-svelte-chat/package.json`:
- Line 23: Update the `@tanstack/ai-svelte-ui` runtime dependency declaration to
use the required workspace:^ range instead of workspace:*, preserving the
dependency name and all unrelated package configuration.
In `@packages/ai-client/src/ui/selectors.ts`:
- Around line 45-55: Update getMappedComponent to unwrap any non-null object
that has a component property, without requiring placement; preserve returning
the original entry when component is absent.
- Around line 79-93: Update resolveInterruptComponent so the tool-approval
branch returns interruptsMap.fallback when interruptsMap.tools has no entry for
interrupt.toolName, while preserving getMappedComponent for mapped tools.
In `@packages/ai-react-ui/src/create-ui.tsx`:
- Around line 61-73: Update ToolProps in packages/ai-react-ui/src/create-ui.tsx
lines 61-73 and packages/ai-vue-ui/src/create-ui.ts lines 56-68 to derive
interrupt from the configured generic ChatInterrupt using
ChatUIToolsOf<TOptions> and ChatUIInterruptsOf<TOptions>, matching
ChatUIToolPart so concrete tool names are preserved. Keep the existing React
cast because ChatUISelectedToolPart.interrupt remains erased.
In `@packages/ai-solid-ui/src/create-ui.tsx`:
- Around line 328-335: Update the Part component to resolve its
ChatUISelectedPart from the original message context rather than constructing a
synthetic single-part message, preserving matched tool-result associations and
configured inline approvals. Pass the resolved selection to SelectedPartView and
derive the inline prop from that selection instead of forcing inline={false}.
In `@packages/ai-svelte-ui/src/create-ui.ts`:
- Around line 31-56: Update ChatUIComponents and the defineComponents, UIChat,
and UIProvider type flow to retain each registered Svelte component’s exported
prop type instead of using unknown, any, Record<string, unknown>, or as never.
Require layout and message registrations to be valid Svelte components with
compatible props, preserve ChatUIComponents<TOptions> through consumers, and add
negative type tests rejecting plain objects and incompatible props.
In `@packages/ai-svelte-ui/src/ui-message.svelte`:
- Around line 10-14: Update the props type in ui-message.svelte so the children
snippet uses Snippet<[Array<ChatUISelectedPart>]> instead of Snippet<[unknown]>,
matching the ChatUISelectedPart array passed by messageParts(ctx, message).
Import or reuse the existing ChatUISelectedPart type, and add a type test
confirming manual renderers can access fields such as key, part, and interrupt.
In `@packages/ai-vue-ui/src/chat.vue`:
- Line 2: Move the deprecation annotations out of the script-setup context so
they attach to the generated default component exports. Update
packages/ai-vue-ui/src/chat.vue at line 2 for Chat and
packages/ai-vue-ui/src/tool-approval.vue at line 2 for ToolApproval by placing
each annotation in a normal script block, or enable Vue Macros setupJsdoc for
both components.
Apply the same fix in `@packages/ai-vue-ui/src/chat-input.vue` at line 2: The same
misplaced annotation affects the ChatMessages component export.

Keep the server and client halves together in both framework guides.
Both pages reference a server route and model while showing only the client half. Add the matching server endpoint snippet to each page, or remove the server-specific text and link.

Render the interrupt slot in the layout example.
The example layout returns only slots.messages. UIChat passes messages, interrupts, and input slots in packages/ai-vue-ui/src/create-ui.ts, Lines 366-398. Because this example registers interrupts.fallback, copied code will not render interrupts. Render slots.interrupts?.() and the input slot when an input component is registered, or update the prose in Line 70.

Use the required workspace dependency range.
Change this runtime dependency to workspace:^. workspace:* does not meet the repository package policy.
Proposed fix
- "`@tanstack/ai-svelte-ui`": "workspace:*",
+ "`@tanstack/ai-svelte-ui`": "workspace:^",As per coding guidelines: dependencies must use workspace:^.

Use the generic ChatInterrupt type in both adapters. ChatUIInterrupt uses AnyClientTool, so it loses configured tool names and the Extract can become never for a concrete TName. Match ChatUIToolPart with ChatInterrupt<ChatUIToolsOf<TOptions>, ChatUIInterruptsOf<TOptions>>. Keep the React cast because ChatUISelectedToolPart.interrupt remains erased.

Preserve selected-part associations in Part.
Line 330 creates a synthetic message with only one part. A manual UI.Part for a tool call cannot receive its matched tool result from the original message. A configured inline approval also cannot render because line 335 passes inline={false}.
Manual <UI.Message> rendering can therefore differ from renderParts() and can omit inline approvals. Pass ChatUISelectedPart into Part, or resolve the part from its original message context.

Preserve component prop types in ChatUIComponents.
layout and message use unknown, so defineComponents accepts plain objects. UIChat then casts layout to any and renders it as a Svelte component. Type each registration with its Svelte component and exported prop type, and preserve ChatUIComponents<TOptions> through UIChat and UIProvider instead of using any, Record<string, unknown>, and as never. Add negative type tests for plain objects and incompatible props.

Type the manual-renderer snippet with ChatUISelectedPart.
messageParts(ctx, message) returns Array<ChatUISelectedPart>, and the {#if children} branch passes it to children. Snippet<[unknown]> exposes the value as unknown, so manual renderers cannot access item fields such as key, part, or interrupt without re-narrowing. Use Snippet<[Array<ChatUISelectedPart>]> and add a type test.

Attach deprecation JSDoc to the public Vue component exports.
The @deprecated tags currently sit above imports in <script setup>, so they document an import rather than the implicit component exports. Consumers therefore do not receive deprecation notices in editor tooling or emitted declarations. Move the annotations to the public exports for Chat, ToolApproval, ChatInput, ChatMessage, and ChatMessages.

Reserve the "fallback" interrupt ID or remove the key collision.
ChatUIRegisteredInterruptId<TOptions> can contain "fallback". Lines 98-100 remove that registered handler from the typed map. A registered interrupt with this ID can only use the untyped fallback component, so its payload and response types are lost.
Reserve "fallback" for the fallback renderer, or move the renderer to a non-colliding key. Add a type test for an interrupt definition with this ID.
