Features
9featsurface the upload failure reason on failed attachment status
featAssistantError taxonomy with severity and display metadata propagated through run error status. behavior note: local runtime run failures now store a structured AssistantError object in message status.error instead of a plain string; useMessageError keeps returning a human-readable string for both shapes, and code reading status.error directly should use isAssistantError or toAssistantError

fixstop isJSONArray from consuming the array index as recursion depth
fixresume the local runtime when a human tool returns a falsy result
fixmake the default attachment adapter work without FileReader (Node, react-ink, SSR) by sharing a single getFileDataURL from @assistant-ui/core/internal, whose base64 fallback chunks large inputs and works on runtimes without Buffer

fixforward
threadId and initialThreadId from useLangGraphRuntime to the underlying thread list runtime, so URL-based thread routing (threadId in, onThreadIdChange out) works with LangGraph the same way it does with the base runtimefixserialize runs in useLangGraphRuntime so a frontend tool result resume never overlaps the run that emitted the tool call. isRunning stays true across the seam, cancel stops the whole turn and drops the queued resume, and a run that aborts or errors drops the sends queued behind it.
fixdrop a frontend tool result for a call that was already answered instead of releasing it as a resume run. A slow frontend tool resolving after a new turn auto-cancelled its dangling call no longer sends a second tool message to the graph.

ActionRegistry and wire $action dispatch end to end. createActionRegistry(handlers) maps $action.type to a handler; omit actions for a read-only render where $dispatch stays un-injected and interactive clicks are silent. the vocabulary's Button/Select/Input/DatePicker attach real event handlers that fire $dispatch($action), merging the user's runtime value into the payload under the reserved $input key so a model-supplied value is never clobbered; an unknown action type degrades to a no-op with a dev warning rather than throwing. HITL resume-value typing is left as unknown (IR doc open question #2); the resume value reaching the runtime is a follow-up.@assistant-ui/react-ink@0.0.31patchGitHub →

2miscrender devtools inline instead of in a hosted iframe. the devtools UI now ships inside the package and renders in an isolated shadow root, so it no longer loads the deployed
devtools-frame web app. DevToolsModal is unchanged at the call site and gains an extensible tab registry via the plugins prop (createDevToolsPlugin, DevToolsPanel).miscredesign the devtools panel and add new inspection capabilities. visually the panel becomes a borderless, flatter floating window (lighter dim backdrop, smaller spring-animated launcher) with a single consolidated top nav bar (underline-pill tabs, multi-instance select, a live status pill, close), a refreshed ChatGPT-style light/dark token theme (bumped --radius, retuned surfaces/borders, new --shadow-window and --shadow-launcher elevation tokens, prefers-reduced-motion handling), and an interactive collapsible JSONTree with copy-to-clipboard replacing the old static JSON dumps throughout.

Features
2feataccept any AbstractAgent in useAgUiRuntime instead of requiring HttpAgent
featforward the full ExternalStoreThreadListAdapter (threads, archivedThreads, onRename, onArchive, ...) through adapters.threadList so server-persisted threads can be registered and switched to; clear messages before onSwitchToThread so the previous thread's messages no longer merge in as a phantom sibling branch; onSwitchToThread can return unstable_resume to reattach to an in-flight run after switching (resumes in the background and requires a ThreadHistoryAdapter with resume, otherwise it reports through onError instead of re-running the agent)
Fixes
2fixattach a TOOL_CALL_RESULT for a prior run's tool call to its owning message instead of synthesizing a duplicate empty-args part
fixkeep failed and aborted runs visible. the synthetic RUN_FINISHED from onRunFinalized used to overwrite RUN_ERROR with a successful status, so failed runs rendered as complete and MessagePrimitive.Error never showed. aborts (which @ag-ui/client routes through onRunFailed) now map to RUN_CANCELLED instead of RUN_ERROR, so the run lands as incomplete/cancelled.

1featadd useTapHost, a React host that commits the resource in the passive phase without blocking paint; the returned per-render effects callback lets descendant consumers mount the commit ahead of their own effects via useEffect(effects). The React bridge hosts (useResource, useResources, useTapRoot) now also commit in useEffect instead of useLayoutEffect.
Fixes
1fixmatch React semantics: support render-phase updates (setState during render re-renders before committing, capped at 25 passes, instead of throwing; discarded render attempts drop their render-phase dispatches like React; updating a resource other than the one currently rendering throws), apply dispatches exactly once across React-discarded and replayed renders of tap sub-roots, run all effect cleanups before any setups within a commit, and compare only the common prefix of deps arrays that change length (with a dev warning)

SimpleTextAttachmentAdapter and SimpleImageAttachmentAdapter work without FileReader. they read files via the browser only FileReader, so sending an attachment in a non browser runtime (e.g. @assistant-ui/react-ink in a terminal) threw ReferenceError: FileReader is not defined. the adapters now feature detect: they keep using FileReader when it exists (browser, and React Native whose Blob polyfill provides it) and fall back to file.text / file.arrayBuffer in Node. output is byte identical across all three environments, so @assistant-ui/react, @assistant-ui/react-native, and @assistant-ui/react-ink all keep re-exporting the same core implementation.@assistant-ui/mcp-docs-server@0.1.34patchGitHub →

2fix· react-ai-sdkmake the package metro-bundleable in react native / expo by serving a client-only entry under the react-native export condition
fix· react-ai-sdkmake the package root bundle on edge, cloudflare workers, deno, and browsers, not just react native. the node-only stdio MCP transport is now resolved through a package.json "imports" condition (
#mcp-stdio), so importing @assistant-ui/react-ai-sdk at root carries the full server toolkit on every target with http/sse MCP working on edge, while stdio MCP throws a clear runtime error only where a subprocess cannot be spawned (browser, react native, edge, workers) instead of breaking the build via @ai-sdk/mcp/mcp-stdio -> node:child_process. node, bun, and deno keep the real stdio transport.@assistant-ui/react-data-stream@0.12.17patchGitHub →

defineToolkit and the tool markers (hitlTool / stubTool / providerTool) now have runtime implementations in @assistant-ui/react-ink, so Ink apps author tools with the same defineToolkit API (and typed args) as the web. An Ink app runs in a single Node process with no client/server boundary, so there is nothing for the "use generative" compiler to split: defineToolkit resolves each tool's type at runtime and no build step is required.Fixes
2fix· react-inkblock Enter submission while the thread is running unless the runtime supports queueing.
ComposerInput called composer.send unconditionally, so pressing Enter mid-run interrupted the active stream even on runtimes with capabilities.queue: false. It now applies the same gate as the web ComposerInput (isRunning && !capabilities.queue no-ops, keeping the typed text). The onSubmit override path is unaffected; apps using it own their submit behavior.@assistant-ui/react-ink-markdown@0.0.23patchGitHub →
