  fixJson treated the - that opens an array element as a complete value, so a stream cut at {"a":[- repaired to {"a":[-]}. That is not valid JSON, parsePartialJsonObject fell into its catch and returned undefined, and callers that fall back to {} dropped every field streamed so far until the next delta landed.

  The INSIDE_ARRAY_START default branch advanced lastValidIndex before delegating to processValueStart, which deliberately leaves it alone for - because a lone minus carries no value yet. Every other value-start site already lets processValueStart own that index, which is why {"a":- and {"a":[1,- truncated correctly and only the first element of an array did not.

• #4167 fcb6baf - feat: add a display presentation hint to tools and a "standalone-tool-call" key to groupPartByType. (@Yonom)

  Tool UIs fall into three buckets: prompting the user (human-in-the-loop), informing the user (generative UI), and traces of what the model is doing (routine frontend/backend tool calls). The first two should be surfaced on their own; the last belongs folded into the chain-of-thought trace. The new display field on a tool lets you place a tool in the right bucket without overloading type:

  ⧉

  const toolkit = {
    ask_user: { type: "human", render: AskUI }, // standalone (forced — can't opt out)
    search_web: { type: "frontend", render: SearchUI }, // inline trace (default)
    checkout: {
      type: "frontend",
      render: CheckoutUI,
      display: "standalone", // opt in
    },
  } satisfies Toolkit;
  

  • display?: "standalone" | "inline" is a client-only presentation hint (it never reaches the model). Defaults to "inline".
  • human tools are always "standalone" and cannot opt out (the type only allows "standalone"). MCP-app tool calls and the built-in generative-UI tool are standalone too. Every other tool defaults to inline and opts in explicitly.
  • groupPartByType gains a synthetic "standalone-tool-call" key that matches all of the above. MessagePrimitive.GroupedParts passes the live tool-UI registry to the groupBy function as a second context argument ({ toolUIs }), and the helper reads it to resolve the registry-driven cases; MCP-app calls are detected from the part alone.
  • The "mcp-app" key on groupPartByType is deprecated in favor of "standalone-tool-call" (a superset). It still works for back-compat.

  The shadcn thread.tsx template is updated to use "standalone-tool-call": [] in place of "mcp-app": [].

• #4133 c4d3eea - forward per-tool providerOptions from useAssistantTool through toToolsJSONSchema and frontendTools into the AI SDK request body, and emit tool entries in alphabetical order so identical tool sets produce byte-identical request bodies for stable prompt caching. react-ag-ui inherits the sort via toAgUiTools, so identical tool sets reach the AG-UI runtime in a stable order regardless of mount order. (@okisdev)

  this lets you opt into provider-specific tool features (e.g. Anthropic's defer_loading, Anthropic Tool Search Tool) without any provider-aware code in assistant-ui:

  ⧉

  useAssistantTool({
    toolName: "get_weather",
    parameters: schema,
    providerOptions: { anthropic: { deferLoading: true } },
    execute: async ({ city }) => fetchWeather(city),
  });
  

  the value is passed through verbatim; the AI SDK provider (@ai-sdk/anthropic, @ai-sdk/openai, ...) interprets it.

Patch Changes#

• #4116 d4f1db4 - fix: preserve parentId on streamed text and reasoning parts (@ShobhitPatra)

  AssistantStreamController dropped parentId for text/reasoning parts written through a withParentId(...) controller: addTextPart/addReasoningPart never attached it, and appendText/appendReasoning reused the open append part across a parentId change. This silently merged parts and broke the AuiTextDelta/AuiReasoningDelta data-stream round trip (including the decoder's own withParentId(...).appendText(...) path).

0.3.16#

Patch Changes#

• #4096 13a12c4 - docs(assistant-stream): fix README usage example and clarify wire-format pairing (@okisdev)

  the README Usage snippet was calling controller.appendText() with no arguments and treating the return value as a writer, but AssistantStreamController.appendText has signature (textDelta: string): void. copy-pasting the old snippet threw TypeError: Cannot read properties of undefined (reading 'append') at the first text.append(...) call. switched the example to the actual API.

  also added a short note that createAssistantStreamResponse returns a standard Web Response (drops into Next.js / Hono / Bun / Deno / Cloudflare Workers; Express and Fastify need a small adapter), and that the emitted bytes are the data stream wire format. on the frontend pair it with useDataStreamRuntime({ api, protocol: "data-stream" }); the default protocol: "ui-message-stream" expects AI SDK v6's SSE-based UI message stream format and will throw Stream ended abruptly without receiving [DONE] marker against this output.

• #3979 9ecda1d - feat(assistant-stream): add resumable stream primitives (@okisdev)

  new assistant-stream/resumable entrypoint for persisting an in-flight AssistantStream and replaying it after a disconnect or reload.

  createResumableStreamContext({ store, ttlMs?, waitUntil?, onAcquire?, onAppend?, onFinalize?, onError? }) returns { run, resume, requireResume, status, delete }.

  createResumableAssistantStreamResponse and createResumeAssistantStreamResponse bridge AssistantStreamController callbacks to any AssistantStreamEncoder.

  createInMemoryResumableStreamStore covers dev and tests; Redis adapters live at assistant-stream/resumable/redis and assistant-stream/resumable/ioredis (peer deps), with pipelined appends and binary chunk values.

  typed errors via ResumableStreamError with codes "missing" | "exists" | "finalized" | "invalid-id".

• #4008 fa4510a - feat: support multi-modal tool results via toModelOutput (@okisdev)

  frontend tools can now project their execution output into multi-modal model content (text + image / pdf / arbitrary file parts), aligning with the AI SDK v6 toModelOutput callback. previously, tool results were always serialized as a single JSON value, so a "read pdf" style tool had no way to send the PDF back to a multi-modal model.

  • assistant-stream exports a new ToolModelContentPart type ({ type: "text", text } | { type: "file", data, mediaType, filename? }) and a ToolModelOutputFunction<TArgs, TResult> callback type. Tool.toModelOutput is wired through unstable_runPendingTools and ToolExecutionStream, attaching the resulting modelContent to the tool-call part on the assistant message.
  • @assistant-ui/core re-exports ToolModelContentPart and adds an optional modelContent?: readonly ToolModelContentPart[] field on ToolCallMessagePart. existing tools and renderers are unchanged.
  • @assistant-ui/react-ai-sdk's frontendTools(...) helper now also registers a toModelOutput on each forwarded tool. it transparently unwraps an envelope that useAISDKRuntime writes when a frontend-executed tool produced modelContent, turning it into AI SDK's { type: "content", value: [...] } output. plain (non-envelope) outputs fall back to the existing { type: "text" | "json", value } shape, so behavior for tools without toModelOutput is unchanged.

  route handlers that adopt toModelOutput also need to pass tools to convertToModelMessages (this is the AI SDK's documented pattern):

  ⧉

  const aiSDKTools = { ...frontendTools(tools ?? {}) };
  streamText({
    messages: await convertToModelMessages(messages, { tools: aiSDKTools }),
    tools: aiSDKTools,
  });
  

  templates and existing examples are unchanged. they keep the simpler convertToModelMessages(messages) form because none of the tools they ship with use toModelOutput. the new tools guide page documents how to opt in.

  reserved key. when a frontend tool defines toModelOutput, its result is persisted in the AI SDK chat as { __aui_modelContent: ToolModelContentPart[], value: <your result> }. tools must not return objects whose top-level key is literally __aui_modelContent, or convertMessage will misread the result. the prefix is namespaced for this reason.

  read/write compatibility for persisted threads. the envelope is recognized by @assistant-ui/react-ai-sdk from this version onward. if you persist UI messages and read them from multiple environments, upgrade every reader before any writer starts producing toModelOutput; otherwise older readers will treat the envelope object as the result and break the affected tool render functions.
