Registers LLM tools and renders custom tool-call UI in assistant-ui (@assistant-ui/react). Covers the current authoring model: a "use generative" file exporting defineToolkit({...}) that co-locates schema, execute, and render and is split across the client/server boundary by the build plugin (withAui from @assistant-ui/next, aui() from @assistant-ui/vite, withAui from @assistant-ui/metro), mounted with Tools({ toolkit }) through useAui and exposed to the model with AISDKToolkit. Covers the tool kinds and their execute markers: backend (plain execute), frontend ("use client" inside execute), human via humanTool()/hitl, provider via providerTool(), external via externalTool(), stubs via stubTool() plus useAuiToolOverrides, and MCP via defineMcpToolkit. Also covers the component-scoped path (makeAssistantTool / useAssistantTool / makeAssistantToolUI / useAssistantToolUI), ToolCallMessagePartProps (status.type running/complete/incomplete/requires-action, args, argsText, result, artifact, a

Implements multi-thread (conversation history) management in assistant-ui apps: rendering the prebuilt `ThreadList` next to `Thread`, or building a custom sidebar with `ThreadListPrimitive` and `ThreadListItemPrimitive` (Root, New, Items, Trigger, Title, Archive, Unarchive, Delete). Covers thread CRUD through the `useAui()`/`useAuiState()` API: `switchToThread`, `switchToNewThread`, and per item `rename`, `archive`, `unarchive`, `delete`, `generateTitle`, `initialize`, plus reading `s.threads.threadIds`/`archivedThreadIds`/`mainThreadId`. Includes cloud-backed persistence via `useChatRuntime` + `AssistantCloud` and a local `useRemoteThreadListRuntime` + `InMemoryThreadListAdapter` path. Use when a user wants a thread list/sidebar, switching, searching, sorting, drag-and-drop, or renaming/archiving/deleting conversations. For single-thread state, messages, or composer use runtime; for cloud auth/persistence setup use cloud.
