Patch Changes#

• #5805 48af3c5 - feat: round-trip a part's providerMetadata.agui through AG-UI's content metadata. An image or file part, whether it sits on the message or inside an attachment, now reaches the agent with whatever the host put in that namespace, and an inbound item puts it back on the rebuilt part, so a snapshot echo resends it instead of dropping it. A file part's own filename still wins over a key of the same name. Text is unchanged, its AG-UI schema has no metadata field. (@okisdev)

• #5807 84ef0df - fix: preserve image filenames through AG-UI snapshots (@Kinfe123)

• #5803 a44c953 - fix: preserve queued messages when cancelling an active run (@Kinfe123)

• #5755 b9d5ba3 - fix: preserve encrypted-only reasoning records across the AG-UI round trip. Under zero data retention an agent sends a ReasoningMessage whose readable content is empty and whose payload is entirely in encryptedValue, and both the adapter and the core normalizer dropped it: the import guarded on empty text, and a reasoning part with neither text nor summary is removed by fromThreadMessageLike. Such a record now rides on metadata.custom.agui.opaqueReasoning of the neighbouring message instead of becoming an unrenderable part, and is replayed into the run input adjacent to that message. A record that sat between an assistant message and its own tool result is replayed after that result, since import folds the result into the assistant message and that boundary no longer exists at export. A runtime configured with showThinking: false is affected too: it previously emitted no reasoning records at all, and now emits { role: "reasoning", content: "", encryptedValue } for each imported record that carried a value, since that option hides reasoning from the UI rather than discarding state the agent needs back. (@okisdev)

• #5752 ee4db08 - fix: keep reasoning, and its signature, across the AG-UI round trip. toAgUiMessages built the run input from extractText, which reads text parts only, so an imported reasoning-only assistant message was discarded as a blank turn and a live assistant message silently lost its reasoning; reloading a thread and sending one more message deleted the reasoning history from what the agent received. Reasoning parts now leave as the standalone reasoning records they arrived as. The runtime also consumes REASONING_ENCRYPTED_VALUE and stores the blob at providerMetadata.agui.encryptedValue, so reasoning from a live run and from an imported ReasoningMessage are both re-emitted with their signature intact rather than replayed unsigned.

  ExternalThreadQueueAdapter is reshaped: enqueue(message, { steer }) splits into

  move(queueItemId, { lane: "steer", insertAfter: null }), clear(reason) is dropped
  (queue clear policy is now host-owned), and steerItems / move / edit and
  QueueItemState.parts are required.

Patch Changes#

• #5461 1fae3c6 - fix: convert file parts placed directly in message content (@okisdev)

  buildUserContent filtered every file part out of message.content, on the stated grounds that binary always flows through message.attachments. That rule was not actually implemented: image and audio content parts, equally binary, were converted from content all along, so only file was excluded. It also guarded nothing, because both composer paths put binary in attachments and leave content as text (the edit composer lifts non-text parts with liftNonTextParts and passes none through), and because content-sourced and attachment-sourced parts land in the same flat InputContent[] with no downstream distinction. The only way a file part reached that filter was a deliberate append(), where it was silently dropped.

• #4533 fa4c23d - fix: order tool-call parts by parentMessageId (@dkachur1)

  The run aggregator appended tool-call parts in wire-arrival order. Because the messages and tool-call channels are not ordered relative to each other on the wire, a tool whose TOOL_CALL_START arrived after a later message's text was rendered below that text instead of under the message that spawned it. Tool-call parts are now placed adjacent to their parentMessageId text part (falling back to append when the parent is unknown), matching the message association the canonical @ag-ui/client already performs.

  Converting persisted AG-UI messages to assistant-ui messages (e.g. when

  reload even though the live REASONING_* (and deprecated THINKING_*) path
  already surfaces them. They are now converted faithfully to a reasoning
  assistant part. activity messages carry a structured payload with no
  assistant-ui message-part equivalent and remain intentionally unmapped.

It now passes the resume generator into startRun, which replays each ChatModelRunResult into the existing assistant message (no new runId, no replayed agent.runAgent). On history load() with unstable_resume, the adapter now feeds history.resume() when present (falling back to a fresh run otherwise), and ResumeRunConfig.stream is typed as the real (options: ChatModelRunOptions) => AsyncGenerator<ChatModelRunResult, void, unknown> instead of unknown. This lets apps that persist their own AG-UI event stream re-attach and continue consuming on reload.

  new public exports from @assistant-ui/core (re-exported from @assistant-ui/react):

  • ExternalStoreSharedOptions, a typed Pick over ExternalStoreAdapter covering the four thread-level optional fields every wrapper forwards: isDisabled, isSendDisabled, unstable_capabilities, suggestions.
  • pickExternalStoreSharedOptions(options), plucks those four fields from a wider options object. the body uses satisfies Required<...> so adding a key to the type without copying it in the function is a compile error rather than a silent missing-field bug.
  • useExternalStoreSharedOptions(options) (from @assistant-ui/core/react), a memoized variant for wrappers that wrap their store in useMemo. lets the wrapper list a single stable shared reference as a dep instead of enumerating the four fields. same satisfies guard internally so the destructure stays in sync with the type.

  internal: every runtime wrapper hook (useChatRuntime, useAISDKRuntime, useLangGraphRuntime, useA2ARuntime, useAgUiRuntime, useAdkRuntime, useStreamRuntime, useOpenCodeRuntime) now uses these helpers instead of inlining the conditional spreads added in #4135. each wrapper sheds 20 to 40 lines of duplicated declarations and conditional spreads; future additions to the shared option set propagate through a single edit in pickExternalStoreSharedOptions instead of touching every wrapper. no user-facing behavior change.

• #4175 2dec3ae - chore: update dependencies (@Yonom)

• #4135 e7c2396 - align the runtime wrapper hooks so every distribution forwards the same set of optional adapter-level fields to useExternalStoreRuntime. closes #4134. (@okisdev)

  useChatRuntime and useAISDKRuntime (which already accepted suggestions) gain three new options:

  • isDisabled, disables the composer input entirely.
  • isSendDisabled, keeps the input usable but makes send() a no-op (paired with composer.canSend).
  • unstable_capabilities, per-thread capability overrides (currently { copy?: boolean }).

  useLangGraphRuntime, useA2ARuntime, useAgUiRuntime, useAdkRuntime, useStreamRuntime, useOpenCodeRuntime gain all four (the three above plus suggestions).

  adapter-level additions, where missing:

  • useChatRuntime / useAISDKRuntime already accepted dictation and voice through the ExternalStoreAdapter adapter shape; this just confirms the typing.
  • useLangGraphRuntime, useA2ARuntime, useAgUiRuntime, useAdkRuntime, useStreamRuntime, useOpenCodeRuntime now accept dictation and voice in their adapters object and forward them through.
  • useOpenCodeRuntime gains an adapters option for the first time (attachments / speech / dictation / voice / feedback).

  every new field is optional and defaults to the prior behavior, so existing call sites need no changes.

• #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.

• #4066 3bc6dc0 - fix(react-ag-ui): preserve arrival order of parts in RunAggregator (@tlecomte)

  The aggregator now strictly preserves the order events arrive from the upstream stream. Each REASONING_START, TOOL_CALL_START, and TEXT_MESSAGE_END acts as a boundary that closes the current active part, so consecutive events of the same type are grouped into one part while interleaved events of a different type produce separate parts in chronological order.

  Previously, the first reasoning block was always moved before the first text part regardless of arrival order, and multiple reasoning cycles were merged into a single block. Both behaviours have been removed.

Patch Changes#

• #3974 1959f3a - feat(react-ag-ui): surface AG-UI interrupt-aware run lifecycle (@okisdev)

  event-parser reads the optional outcome on RUN_FINISHED and forwards both success and interrupt variants; the subscriber subscribes to onRunFinishedEvent (with onRunFinalized as a fallback for older servers). RunAggregator maps outcome.type === "interrupt" to requires-action with reason: "interrupt" and writes the interrupts to metadata.custom.agui.interrupts. useAgUiRuntime returns an AgUiAssistantRuntime augmented with unstable_getPendingInterrupts and unstable_submitInterruptResponses; the latter validates coverage and expiry on the client, then issues a fresh run with RunAgentInput.resume populated. the runtime state snapshot is also synced onto the agent before each run so state actually reaches the protocol layer.

• #3977 876abd1 - feat(react-ag-ui): tighten interrupt lifecycle (@okisdev)

  append, reload, and resume now refuse to start a new run while interrupts are still pending on the thread; the call throws with a message pointing at submitInterruptResponses instead of letting the request hit the wire and rely on the agent to reject it (AG-UI interrupts spec rule 4).

  AgUiInterrupt.reason is typed as AgUiInterruptReason ("tool_call" | "input_required" | "confirmation" | (string & {})), so the spec values autocomplete while string extension stays open.

  onRunFinishedEvent now ignores payloads that parse as a different event type, so a misrouted callback can no longer suppress the onRunFinalized fallback.

• #4017 1802e08 - fix(react-ag-ui): adopt TEXT_MESSAGE_START.messageId as the assistant ThreadMessage.id (@okisdev)

  AgUiThreadRuntimeCore now inserts the assistant placeholder under an optimistic id (generateOptimisticId), then atomically reassigns the message id to the server-supplied messageId the first time RunAggregator observes one (on TEXT_MESSAGE_START, TEXT_MESSAGE_CONTENT, TEXT_MESSAGE_END, or TOOL_CALL_START.parentMessageId). assistantHistoryParents and recordedHistoryIds migrate with the id, so persistAssistantHistory, addToolResult, and downstream lookups keep working and resolve to the canonical AG-UI id. This brings the streaming path in line with MESSAGES_SNAPSHOT imports, which were already keyed on the server id.

  TOOL_CALL_RESULT.messageId is now surfaced as unstable_toolMessageId on the tool-call part, so tool messages round-trip back to AG-UI with their original id instead of a synthetic ${toolCallId}:tool value.
