Entry point for TanStack AI skills. Routes to chat-experience, tool-calling, media-generation, structured-outputs, adapter-configuration, ag-ui-protocol, middleware, locks, custom-backend-integration, and debug-logging, plus the skills shipped by companion packages (@tanstack/ai-persistence, @tanstack/ai-code-mode), and computer use (@tanstack/ai-computer-use). Use chat() not streamText(), openaiText() not createOpenAI(), toServerSentEventsResponse() not manual SSE, middleware hooks not onEnd…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TanStack AI — Core Concepts TanStack AI is a type-safe, provider-agnostic AI SDK. Server-side functions live in `@tanstack/ai` and provider adapter packages. Client-side hooks live in framework packages (`@tanstack/ai-react`, `@tanstack/ai-solid`, etc.). Always import from the framework package on the client — never from `@tanstack/ai-client` directly (unless vanilla JS). ## Sub-Skills | Need to... | Read | | ------------------------------------------------- | --------------------------------------------- | | Build a chat UI with streaming | ai-core/chat-experience/SKILL.md | | Survive a browser reload (no extra package) | ai-core/client-persistence/SKILL.md | | Add tool calling (server, client, or both) | ai-core/tool-calling/SKILL.md | | Generate images, video, speech, or transcriptions | ai-core/media-generation/SKILL.md | | Get typed JSON responses from the LLM | ai-core/structured-outputs/SKILL.md | …

How to install
mdr add tanstack/ai/ai-core@sha256:cfbeeb560d4adbbfThe line at the top of this page pins the label git:20261021.824ee98, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
