agent-skills

Stream overview, CLI, and router for Chat, Video, Feeds, Moderation, and Agents. Use for any Stream task: building or integrating Stream into web, iOS, Android, React Native, Flutter, Unity, or Unreal apps, building voice or text AI agents with Stream Agents, querying Stream data, running getstream CLI commands, looking up Stream SDK docs, or migrating (from Sendbird, or Feeds v2 to v3). Routes to the right skill.

Build, integrate, and review 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, read-only integration reviews before going live, AI assistants, voice agents and LLM chat (ChatGPT-style apps, streaming replies, thinking indicators, stop generating, tool calls, generative UI) with stream-chat-android-ai-compose and Stream Agents, 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).

Compatibility entrypoint for requests naming stream-builder. Routes app work to the appropriate platform skill.

Compatibility entrypoint for requests naming stream-docs. Uses getstream docs for SDK documentation lookups.

Generate the v2 -> v3 sync mapping for a Stream Activity Feeds app by sampling its live v2 activities and reactions and, when the app's v2 integration code is available, reading its write paths, and, from that code, plan how the app's code moves from v2 to v3. 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?', when asked how to port an app's v2 Feeds code to v3, 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, porting plan. The same mapping drives both the live syncer and the bulk exporter.

Build, integrate, review, migrate to, and answer how-to questions for Stream Chat, Video, and Feeds in Flutter / Dart apps. Supports stream_chat_flutter (pre-built Chat UI), stream_chat_flutter_core (custom Chat UI), stream_video_flutter (calls, ringing, audio rooms, livestreaming), and stream_feeds (Activity Feeds v3, no pre-built UI). Routes each request to the exact official Flutter docs page, fetches it live, and applies it - with a curated setup flow, a push / ringing runbook, design-matching and custom-UI runbooks, a Sendbird -> Stream Chat migration runbook, a read-only integration review before going live (including livestream launches), and Flutter-specific pitfalls.

Build, integrate, audit, or upgrade Stream Chat, Video, Feeds, and Moderation in React / Next.js web apps - the default skill for web work. Scaffold a new app, add Stream to an existing project, review an integration, upgrade an SDK major, or migrate from Sendbird. Covers team messaging, DMs, video conferencing, livestreaming, social feeds, AI assistants (including generative UI with A2UI / OpenUI), and apps built on Stream Agents (voice and text agents, @stream-io/stream-agents). Web React only - React Native uses stream-react-native.

Build, integrate, audit, or upgrade Stream Chat, Video, and Feeds in React Native CLI and Expo / Expo Router apps, and answer RN / Expo how-to questions about them. Scaffold a new app, add Stream to an existing project, review an integration, upgrade an SDK major, migrate from Sendbird (@sendbird/chat, @sendbird/uikit-react-native), or build an AI assistant / ChatGPT-style app on the Chat SDK's ai-components (replacing the deprecated @stream-io/chat-react-native-ai), or one on Stream Agents. Covers channel lists, messages, MessageComposer, threads, the attachment picker, audio messages, offline support, push notifications, video calls, CallContent and ParticipantView, ringing, livestreams, audio rooms, StreamFeeds activity / timeline / notification feeds, comments, reactions, follows, and theming or matching a design, with stream-chat-react-native, stream-chat-expo, @stream-io/video-react-native-sdk, and @stream-io/feeds-react-native-sdk. React Native and Expo only - web React uses stream-react.

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, reasoning and tool-call steps, tool approvals, device-side tools, a voice agent's transcript shown as a conversation) 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.
