Stream router for Chat, Video, Feeds, and Moderation. Use when the user wants to build a new app with Stream, scaffold a project, add Chat/Video/Feeds/Moderation to an existing app, integrate Stream, audit or migrate an integration, build for Swift/SwiftUI/UIKit/iOS/Xcode/Android/Kotlin/React Native/Expo/Flutter, query Stream data, list channels, list calls, show flagged messages, find users, run getstream CLI commands, install the Stream CLI, set up Stream, configure moderation, search Stream SDK documentation, or look up Stream React/iOS/Android/Node/Flutter/Unity SDK methods. Routes to the right sub-skill based on the task.

Build and integrate Stream Chat, Video, and Feeds in Android apps. Use for Jetpack Compose, Android Studio, and Gradle project work — including Stream package setup, auth and token wiring, screen blueprints, and any follow-up Stream UI work such as adding screens, navigating between channel list and channel/message screens, channel tap handling, deep links, push routing, theming, custom channel/message UI, video calling flows (joining/starting calls, ringing, custom call controls and participant tiles), and Feeds surfaces (timeline, activity composer, threaded comments, follow graph / profile, notification feed, stories).

The framework-agnostic Stream builder (Steps 0-7 scaffold + enhance + Video audit), being extended to support app kinds beyond web. Use ONLY when the user explicitly names 'stream-builder' or '/stream-builder'. Web React / Next.js work - 'build me a chat app', 'scaffold', 'create a new ...', 'add Chat/Video/Feeds to this app', 'integrate Video', livestreaming, video conferencing, team messaging, direct messaging, social feed - defaults to the stream-react skill, not this one. Not auto-selected for generic web build requests.

Search live Stream SDK documentation for Chat, Video, Feeds, and Moderation. Look up how a Stream React/iOS/Android/Node/Flutter/Unity/Angular hook, component, or method works. Answer how-to questions about any Stream SDK across every framework and version. Triggers on 'docs', 'documentation', explicit SDK tokens (Chat React, Video iOS, Feeds Node, Moderation), and 'how do I ... in <framework>' phrasing.

Generate the v2 -> v3 sync mapping for a Stream Activity Feeds app by sampling its live v2 activities and reactions. Use when setting up a Feeds v2 to v3 migration, when asked to build, review, or debug a v3 sync mapping, when someone asks 'what mapping do we need for our app?', or when a migrated activity lands in v3 with missing text, missing attachments, comments that are not comments, or bookmarks that went missing. Triggers on v3sync, v2 to v3, feeds migration, activity feeds migration, sync mapping, extra_context, reaction kinds, comments and bookmarks mapping. The same mapping drives both the live syncer and the bulk exporter.

Build and integrate Stream Chat, Video, and Feeds in Flutter apps. Use for Flutter/Dart project work with Stream package setup, auth wiring, and widget blueprints. Supports stream_chat_flutter (pre-built Chat UI), stream_chat_flutter_core (custom Chat UI), stream_video_flutter (Video calling and livestreaming), and stream_feed / stream_feed_flutter_core (Activity Feeds, no pre-built UI). Also migrates Flutter apps from the Sendbird Chat SDK (sendbird_chat_sdk / sendbird_uikit) to Stream Chat.

Build, enhance, audit, or migrate a React / Next.js web app with Stream (Chat, Video, Feeds, Moderation) - the default for all web React work. Scaffold Next.js + Tailwind + Shadcn + Stream React SDKs (Steps 0-7). Add Chat/Video/Feeds/Moderation to an existing React project. Audit a Stream Video integration. Migrate an SDK version (v13 -> v14) or a Sendbird (@sendbird/chat, @sendbird/uikit-react) app. Build AI assistants / LLM chat (ChatGPT-style apps, streaming replies, stop generating) with @stream-io/chat-react-ai. Triggers on 'build me a ... app', 'scaffold', 'add Chat to this app', 'integrate Video', 'upgrade'/'migrate'/'bump ... version', 'migrate from Sendbird', 'AI assistant', 'ChatGPT clone', and tokens: stream-chat-react, @stream-io/video-react-sdk, @stream-io/feeds-react-sdk, @stream-io/chat-react-ai, useCreateChatClient, StreamVideo, MessageList. Covers livestreaming, video conferencing, team messaging, direct messaging, social feed. Web React only - not React Native (use stream-react-native).

Builds, integrates, migrates, audits Stream Chat, Video, and Feeds in React Native CLI and Expo apps. Use when scaffolding an RN/Expo app, adding Stream to an existing app, upgrading a Stream SDK (Chat v8->v9, Feeds v2->v3), migrating from Sendbird (@sendbird/chat, @sendbird/uikit-react-native), building AI assistants / LLM chat (streaming, stop generating) with @stream-io/chat-react-native-ai, answering RN/Expo how-to questions, or customizing Stream RN UI. Triggers on React Native, Expo, Expo Router, stream-chat-react-native, stream-chat-expo, @stream-io/video-react-native-sdk, @stream-io/feeds-react-native-sdk, ChatGPT clone, channel list, message list, MessageComposer, threads, attachment picker, audio messages, offline support, push notifications, video call, livestream, audio room, ringing, CallContent, ParticipantView, activity/timeline/notification feed, StreamFeeds, comments, reactions, follows, and theming. React Native and Expo only - not web React (use stream-react), not Moderation review UI.

Build, integrate, migrate to, and answer how-to questions for Stream Chat, Video, and Feeds in Swift / SwiftUI / UIKit / iOS apps - including AI assistants and agentic experiences (ChatGPT-style apps, LLM bots in chat, streaming responses, thinking indicators, client-side MCP tools) with the StreamChatAI components. Routes each request to the exact official iOS docs page, fetches it live, and applies it - with a curated setup flow, an AI integration runbook, a Sendbird -> Stream Chat migration runbook, and iOS-specific pitfalls.

Build, integrate, and answer how-to questions for Stream Chat and Stream Video in Unity Engine games and apps. Use for Unity / C# / MonoBehaviour project work - the Chat .unitypackage and the Video UPM package, StreamChatClient / StreamVideoClient wiring, ConnectUserAsync and tokens, channels and messages, calls and participant tracks, camera and microphone devices, building the UI yourself on UGUI or UI Toolkit, IL2CPP, and Android / iOS / desktop / WebGL player settings. Triggers on unity, unity engine, unity 6, unity 2022, monobehaviour, .unitypackage, Packages/manifest.json, asmdef, il2cpp, ugui, rawimage, audiosource, webcamtexture, StreamChatClient, IStreamChatClient, IStreamChannel, StreamVideoClient, IStreamVideoClient, IStreamCall, StreamVideoTrack, in-game chat, unity video call. Chat and Video only - there is no Stream Feeds SDK for Unity.

Build, integrate, and answer how-to questions for Stream Chat in Unreal Engine games and apps. Use for Unreal Engine / UE5 / C++ / Blueprint / UMG project work - plugin install per engine version, StreamChatClientComponent wiring on the HUD, ConnectUser and tokens, channels and messages, the shipped WBP_* chat widgets, theming, cooking, and iOS / Android / desktop packaging. Triggers on unreal, unreal engine, ue5, ue 5.7, ue 5.8, .uproject, .uplugin, Build.cs, umg, blueprint, widget blueprint, StreamChat plugin, UStreamChatClientComponent, UChatChannel, FChannelProperties, WBP_TeamChat, in-game chat, game chat. Chat only - there is no Stream Video or Feeds SDK for Unreal.
