Expert guide for Backend.AI distributed computing platform. Automatically activates when users ask about: - Backend.AI architecture, components (Manager, Agent, Storage Proxy, Webserver, App Proxy) - Features (session scheduling, Sokovan orchestrator, multi-tenancy, resource allocation) - APIs (REST, GraphQL), authentication, RBAC authorization - Container runtime (kernels, jail sandbox, hook library, virtual folders) - Accelerator support (CUDA, ROCm, TPU, NPU, Graphcore IPU) - Client SDKs (Python, Java, JavaScript, PHP) - Setup, requirements (Python 3.13+, Docker, PostgreSQL, Redis, etcd) - How WebUI connects to/interacts with Backend.AI backend - Plugin interfaces, development setup, infrastructure Use when user mentions "Backend.AI", "backend.ai", "Sokovan", component names, or asks about the backend platform this WebUI connects to. For this deployment's live data, a GraphQL field's meaning, or a status value the UI shows, use the `bai-agent` skill instead — it queries the manager and the schema.

Post a Korean release risk digest to a Microsoft Teams thread, grouped by risk category. Runs scripts/release-risk-report.mjs over a ref range and renders the result as a short HTML message: new features and change hotspots first, then version-gating gaps (@since), untranslated keys, UI without e2e cover, and manual gaps. Use when someone gives a Teams thread URL and asks to summarize a release, an rc, or a branch there — "이번 릴리즈 리스크 팀즈에 올려줘", "이 스레드에 정리해서 알려줘", "post the release risk report to Teams", "/release-train-prep". With --train it also opens the release train: reads the version from the thread's own "Final train to vX.Y.Z" title, creates the "Final Train to v<version>" Jira Story (after user confirm) and posts the kickoff + digest into the thread — "트레인 이슈 만들어줘", "릴리즈 트레인 준비해줘", "이 스레드로 트레인 준비해줘", "release train 시작". PREPARATION ONLY — it never creates a release branch, tag, or GitHub release; "릴리즈 찍어줘 / 릴리즈 만들어줘 / cut the release / rc 릴리즈" is create-release, not this skill.

关于在 React 应用中使用 lottie-react 集成 Lottie 动画的指南

diamitani Bundle

Installs and configures assistant-ui in a project via the CLI, and picks the right runtime for a backend. Use for first-time install, scaffold, or config: `npx assistant-ui@latest create my-app` (templates default, minimal, cloud, cloud-clerk, langgraph, mcp), `npx assistant-ui@latest init [--yes] [--overwrite]` in an existing Next.js app, or `npx assistant-ui@latest add` registry components (markdown-text, thread-list). Also use to choose a runtime hook for a backend: useChatRuntime (AI SDK), useLangGraphRuntime, useAgUiRuntime, useA2ARuntime, useLocalRuntime (custom streaming API), or useExternalStoreRuntime (Redux/Zustand). Covers Vite/TanStack Start setup, shadcn styling, the playground --preset flag, and avoiding the deprecated @assistant-ui/styles and @assistant-ui/react-ui packages. For upgrading an existing install or post-upgrade breakage use update; for building UI from raw parts use primitives.

diamitani Bundle

Registers LLM tools and renders custom tool-call UI in assistant-ui (@assistant-ui/react). Use when adding frontend-only tools with makeAssistantTool / useAssistantTool (browser actions like clipboard, navigation, localStorage, async-generator streaming, AbortSignal), rendering backend AI SDK tool() calls with makeAssistantToolUI / useAssistantToolUI (status.type running/complete/incomplete/requires-action, args, result, artifact via ToolCallMessagePartProps), building generative UI from tool results, or implementing human-in-the-loop and approval flows (addResult, resume with context.human(), respondToApproval for server-side needsApproval gates). Covers registering tool components inside AssistantRuntimeProvider and the case-sensitive toolName matching that connects a tool to its UI. Reach for this when tool UI is not rendering, a tool is not being called, or a result is not showing.

diamitani Bundle

Upgrades an existing assistant-ui project to current releases and executes the resulting migrations. Use when the user wants to update, upgrade, bump, or migrate @assistant-ui/react, @assistant-ui/react-ai-sdk, ai, or @ai-sdk/react, hits peer-dependency conflicts or post-upgrade type errors, or must apply renamed APIs after a version jump. Detects installed versus latest versions via npm ls / npm view, then routes through breaking-change references for each jump (AI SDK v4/v5 to v6; assistant-ui 0.8.x to 0.14.x): useAssistantApi to useAui, runtime.threadList to runtime.threads, ThreadPrimitive.ViewportSlack removal, the primitives components prop to children render functions, toDataStreamResponse to toUIMessageStreamResponse, maxSteps to stopWhen: stepCountIs(n). Runs npx assistant-ui@latest upgrade, pnpm/npm add @latest, and npx tsc --noEmit to verify. For a first-time install or fresh scaffold (not an upgrade) use setup instead.

diamitani Bundle

Guide to the assistant-ui runtime system, single-thread state, and the imperative runtime API in @assistant-ui/react. Use when creating a runtime (useLocalRuntime with a ChatModelAdapter, useExternalStoreRuntime for Redux/Zustand, useRemoteThreadListRuntime), wiring AssistantRuntimeProvider, or reading/mutating thread, message, and composer state and events. Covers the unified hooks useAui, useAuiState, useAuiEvent (composer.send, thread.runStart, thread.runEnd), legacy hooks (useAssistantRuntime, useThreadRuntime, useMessageRuntime, useComposerRuntime, useThread, useThreadMessages), the AssistantRuntime/ThreadRuntime/MessageRuntime/ComposerRuntime hierarchy, thread operations (append, cancelRun, message().edit/reload), capabilities, and types (ThreadMessage, MessagePart, MessageStatus, ChatModelRunResult). Use for provider "Cannot read property of undefined" errors or state not updating. For multi-thread list UI and switching between conversations use thread-list instead.

diamitani Bundle

Grounding an assistant in your app with assistant-ui copilots (@assistant-ui/react). Use when steering assistant behavior with useAssistantInstructions, feeding lazy app-state context via useAssistantContext({ getContext }), exposing rendered components with makeAssistantVisible(Component, { clickable, editable }), building two-way interactable state with useAssistantInteractable and Interactables(), or registering instructions and tools imperatively through useAui().modelContext().register({ getModelContext }). Reach for this when the assistant should read the current page, click or edit UI, or read and update component state through auto-generated update_{name} tools. For LLM tools and tool-call UI use the tools skill; for runtime and thread state use the runtime skill.

diamitani Bundle

Render and customize assistant message text as markdown in assistant-ui. Use when displaying model output as formatted markdown with MarkdownTextPrimitive from @assistant-ui/react-markdown wired into the MessagePrimitive.Parts text branch, configuring remarkPlugins (remark-gfm, remark-math) and rehypePlugins (rehype-katex), or memoizing components with unstable_memoizeMarkdownComponents. Covers code-block syntax highlighting via react-shiki or react-syntax-highlighter registered as SyntaxHighlighter in components/componentsByLanguage, LaTeX math rendering with KaTeX, Mermaid diagrams gated on stream completion, custom math delimiters via preprocess, and the StreamdownTextPrimitive alternative from @assistant-ui/react-streamdown with built-in Shiki/KaTeX/Mermaid and block streaming. For general chat UI composition route to primitives.

diamitani Bundle

Lets end users add, authenticate, and manage MCP servers from the browser in assistant-ui apps with @assistant-ui/react-mcp. Use when building user-managed MCP server UIs: mounting McpManagerResource via useAui({ mcp }), declaring presets with defineConnector, dropping in McpConfigDialog, or composing McpManagerPrimitive (Root, Connectors, CustomServers, AddCustomTrigger), McpServerPrimitive (Root, Name, Icon, Status, ConnectButton, DisconnectButton, OAuthLink, RemoveButton, Error), and McpAddFormPrimitive (NameField, UrlField, AuthSelect, AuthFields, Submit, Cancel). Covers auth modes none/bearer/oauth, the OAuth flow with McpOAuthCallback, connection states, storage via McpLocalStorage/McpMemoryStorage/McpCustomStorage, reading state with useAuiState (s.mcp, s.mcpServer), and imperative addCustomServer/connect/callTool. Distinct from developer-defined backend @ai-sdk/mcp tools in the tools skill. Reach for this when connected-server tools are missing, OAuth never completes, or servers do not persist.

diamitani Bundle

Builds and customizes assistant-ui chat UI from composable, unstyled @assistant-ui/react primitives that follow Radix-style part composition. Use when assembling or styling a custom Thread, Composer, message rendering, action bar, or branch picker from building blocks: ThreadPrimitive (.Root, .Viewport, .Messages, .Empty, .ScrollToBottom), ComposerPrimitive (.Input, .Send, .Cancel, .Attachments), MessagePrimitive (.Parts/.Content, .Error), ActionBarPrimitive (.Copy, .Edit, .Reload, .Speak, feedback, .ExportMarkdown), BranchPickerPrimitive, AttachmentPrimitive, ThreadListPrimitive, ThreadListItemPrimitive. Covers MessagePrimitive.Parts children render functions for text, image, reasoning, and tool-call parts; conditional rendering with AuiIf (deprecated .If); and gotchas like wrapping in AssistantRuntimeProvider and adding className since primitives ship unstyled. For prebuilt drop-in UI and scaffolding use setup; for multi-thread sidebar behavior use thread-list.

diamitani Bundle

Overview and router for assistant-ui, the React library for building AI chat interfaces from composable primitives. Use for high-level, cross-cutting, or architecture-overview questions: choosing packages, picking a runtime, or understanding the layered model (RuntimeCore, Runtime, context hooks, primitives) and message model. Covers the `@assistant-ui/react` core plus `@assistant-ui/react-ai-sdk`, `@assistant-ui/react-langgraph`, `assistant-stream`, and `assistant-cloud`; `AssistantRuntimeProvider`; the primitives `ThreadPrimitive`, `MessagePrimitive`, `ComposerPrimitive`; the hooks `useAui`, `useAuiState`, `useAuiEvent`; and runtime selection across `useChatRuntime`, `useExternalStoreRuntime`, `useLangGraphRuntime`, `useLocalRuntime`. For a specific area route to a focused sibling instead: setup, runtime, primitives, tools, streaming, cloud, thread-list, or update. Not for hands-on tasks already owned by those siblings.

diamitani Bundle

Adds tracing, telemetry, and observability to an assistant-ui backend. Use when wiring an AI SDK route handler (streamText/generateText, toUIMessageStreamResponse) to a tracing backend: Langfuse via OpenTelemetry (LangfuseSpanProcessor and NodeSDK in instrumentation.ts, experimental_telemetry isEnabled, propagateAttributes with traceName/userId/sessionId, langfuseSpanProcessor.forceFlush on serverless), LangSmith via wrapAISDK(ai) from langsmith/experimental/vercel (createLangSmithProviderOptions, awaitPendingTraceBatches), or Helicone via createOpenAI baseURL https://oai.helicone.ai/v1 with the Helicone-Auth header. Also covers rendering collected spans with @assistant-ui/react-o11y headless primitives (SpanResource, SpanPrimitive Root/Indent/CollapseToggle/StatusIndicator/TypeBadge/Name/Children, SpanByIndexProvider, SpanData/SpanState) mounted via useAui/AuiProvider from @assistant-ui/store. Use for missing or empty traces, edge vs nodejs runtime telemetry, serverless flush issues, or trace waterfalls.
