Keeps Alem's launch post structure and title, with a broader opening about the AI experiences people can build and a light conversational edit throughout. Adds Tanner to the shared byline.

Clarifies the stable-core and experimental-harness distinction, upgrade guidance, and harness recovery and permission limits. Replaces unverified test counts with the confirmed end-to-end test setup.

Validation: Markdown formatting and full pnpm test checks.

Summary by CodeRabbit

  • Documentation
    • Updated the TanStack AI 1.0 article to distinguish stable core APIs from the experimental harness and clarify which packages should be upgraded together.
    • Revised upgrade instructions and updated details about testing, harness behavior, persistence limits, and coding-agent tools.
    • Removed an outdated claim about CI type-checking documentation samples and refreshed the closing guidance.

@AlemTuzlak could you give this follow-up to #1408 a read? I’d like your feedback on the broader positioning around the AI experiences people can build, and whether the more conversational rewrite keeps the technical details measured and accurate. I’ve preserved the original byline and publication metadata; we can discuss attribution here too.

The article distinguishes stable core APIs from experimental harness APIs. It updates the upgrade guidance to keep harness packages on 0.x and changes introductory wording.
Testing and release details
src/blog/tanstack-ai-1-0.md
The article describes end-to-end tests that use deterministic model fixtures. It removes claims about documentation sample type-checking and the number of merged feature pull requests.
Harness behavior and usage guidance

2. Update every `@tanstack/ai*` package to 1.0 at the same time. Remove `@tanstack/ai-react-ui`, `@tanstack/ai-solid-ui`, and `@tanstack/ai-vue-ui` if you use them. These three get no 1.0.
2. Update your stable `@tanstack/ai*` packages to 1.0 at the same time. The experimental harness packages stay on 0.x. Remove `@tanstack/ai-react-ui`, `@tanstack/ai-solid-ui`, and `@tanstack/ai-vue-ui` if you use them. These three don't have 1.0 releases.

L262: Type-safe, provider-agnostic TypeScript SDK for building streaming chat, tool-calling agents, structured outputs, realtime voice, media generation, and framework-native AI apps.
L263: 
L264: TanStack AI is built from composable activities and provider adapters. Use one provider or switch between many. Import only chat, or add image, audio, video, speech, transcription, summarization, realtime, Code Mode, devtools, and framework bindings as your app needs them.

L268: 
L269: Teach your coding agent TanStack AI before you write a line. The skills in 【152†`skills/`】 are user-level: install once, and in every project your agent recommends TanStack AI, maps a task to the package that covers it, installs it, then loads that package&#39;s own `SKILL.md` through TanStack Intent.

L289:   * Structured output flows backed by JSON Schema, Zod, ArkType, Valibot, or plain JSON Schema.
L290:   * Multimodal prompts and responses that include text, images, audio, video, and documents.
L291:   * Image, audio, video, speech, transcription, and summarization workflows using a shared generation client pattern.
L292:   * Realtime voice chat with provider adapters for realtime sessions and token minting.
L293:   * Code Mode agents that let an LLM write and execute TypeScript in an isolated sandbox to orchestrate tools with loops, branches, and parallel calls.
L294:   * Devtools and observability pipelines for inspecting messages, tool calls, stream chunks, errors, usage, and OpenTelemetry traces.

Portable Agent Skills (SKILL.md) as a first-class `chat()` middleware for TanStack AI

`withSkills` renders a short catalog of the skills you offer into the system prompt and gives the model a `load_skill` tool. The model reads the catalog, picks a skill, and pulls the full instructions only when it needs them — so a large skill library does not tax every request. This is the portable path: it runs on any tool-calling model, with no provider sandbox. For skills that run in a provider&#39;s own sandbox, see Provider Skills; the two do not mix in one call.

## Installation
    
    npm install @tanstack/ai-skills
    # or
    pnpm add @tanstack/ai-skills
    # or
    yarn add @tanstack/ai-skills
Pair with `skillsCatalogPlugin` from `/node` in your Vite config
Your own `SkillSource`  | —  | Skills in S3, a database, a registry

`aggregate`, `dedupe`, `filter`, `cache`, and `combineSources` compose these.

### Writing your own source

Implement the `SkillSource` contract, then prove it with the conformance suite the package ships:
    
    import { runSkillSourceConformance } from &#39;@tanstack/ai-skills/testing&#39;
    import { s3Skills } from &#39;./s3-skills&#39;
    
    runSkillSourceConformance(() =&gt; s3Skills(makeTestBucket()), &#39;s3&#39;)

It checks the things that break in production: a missing skill throws rather than returning empty, resources load while a path like `../../etc/passwd` is rejected, `revision()` is stable across identical content, and concurrent `list()` calls stay consistent. The optional parts of the contract are only checked when you implement them — the resource cases need both `listResources` and `readResource`, and the revision case needs `revision` — so a source that cannot represent them is skipped rather than failed. `vitest` is an optional peer dependency for this entry point.

# @tanstack/ai-acp

Shared Agent Client Protocol (ACP) plumbing for TanStack AI harness adapters — the code that turns a coding-agent CLI (`grok`, `gemini --acp`, …) into a `chat()` backend inside a sandbox.

Most apps should use a harness package directly (`@tanstack/ai-grok-build`, …). Reach for `@tanstack/ai-acp` when:

  * you want to plug an ACP agent that has no dedicated adapter package into a sandbox — use `acpCompatible` (the `openaiCompatible` of harnesses), or
  * you are building or extending a harness adapter and need the transport, session, permission, and stream-translation layers in one place.

# 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).
Give the model a catalog of SKILL.md skills  | See `@tanstack/ai-skills` package skills

## Companion packages

Some capabilities live in their own package and ship their own skills. Install the package, then read its skills — do not guess the API from this file.

### `@tanstack/ai-persistence` — durable chat state

Makes a conversation survive a reload, a server restart, a second device, or a paused tool approval. It ships the store contracts (`MessageStore`, `RunStore`, `InterruptStore`, `MetadataStore`), the `withPersistence` / `withGenerationPersistence` middleware, `reconstructChat` for server-side hydrate, an in-memory reference backend, and a conformance testkit. Multi-instance locks are not in this package — `LockStore` / `withLocks` ship in `@tanstack/ai/locks`; see ai-core/locks. The `runs` store contract is typed against run lifecycle types (`RunStatus`, `RunRecord`, `RunStore`, `defineRunStore`, `InMemoryRunStore`), which ship in `@tanstack/ai` itself; see ai-core/middleware.

It does not ship a backend for your database — you implement the stores against Postgres, SQLite, D1, Mongo, or whatever you run, and the package&#39;s skills walk you through it (including Drizzle, Prisma, and Cloudflare recipes).
    
    pnpm add @tanstack/ai-persistence
    npx @tanstack/intent@latest install

The skills ship inside the package, so they only exist on disk once it is installed — the second command re-scans `node_modules` and wires them into the agent config. Until then the paths below resolve to nothing.

Entry point: `node_modules/@tanstack/ai-persistence/skills/ai-persistence/SKILL.md`

Need to...  | Read
--- | ---
Wire server-side chat history, runs, interrupts  | ai-persistence/server/SKILL.md
Implement the store interfaces for your DB  | ai-persistence/stores/SKILL.md
Write the adapter for the DB your app runs  | ai-persistence/build-*-adapter/SKILL.md

Browser-side persistence is not in this package — it ships with the framework packages, so read ai-core/client-persistence instead.

### `@tanstack/ai-code-mode` — LLM code execution

See the `ai-code-mode` skill in that package.

### `@tanstack/ai-skills` — portable Agent Skills at runtime

Gives the model a library of `SKILL.md` skills it can load on demand, on any provider, via the `withSkills` middleware and a `load_skill` tool. Skills come from `inlineSkill`, `skillDirectory`, or a build-time bundle. This is the runtime feature for the model inside your app, not the coding-assistant skills this file is part of, and not the hosted `codeExecutionTool` / `shellTool` skills (those run in a provider sandbox).
    
    pnpm add @tanstack/ai-skills
    npx @tanstack/intent@latest install

Entry point: `node_modules/@tanstack/ai-skills/skills/ai-skills/SKILL.md`

<excerpt>citeturn0search3 [wordlim: 200] Crawled: 2 weeks ago; A new token for `gitSource({ auth: { token } })` (for example, an hourly GitHub App token) no longer changes the sandbox key, so `reuse: &#39;thread&#39;` finds the same sandbox again. ... The native factories throw it (or add validation): `codeExecutionTool` (`@tanstack/ai-anthropic`) frames its 8-skill cap, and `shellTool` (`@tanstack/openai-base`) now validates `skill_id` format instead of nothing. `@tanstack/ai-sandbox` reuses the shared skill-directory walk from `@tanstack/ai-skills`.
The URL, ref, depth, and username still change the key.

### Patch Changes

`withSkills(sources, options?)` renders a skill catalog and a `load_skill` tool so any tool-calling model can load skills on demand, on any provider, with no server sandbox. Skills come from `inlineSkill`, `skillDirectory` (`/node`), or a build-time `staticSkills` bundle, and compose via `aggregate`/`dedupe`/`filter`/`cache`. `createResourceTool` exposes a skill&#39;s bundled files through `read_skill_resource`, and `runSkillSourceConformance` (`/testing`) validates custom `SkillSource` adapters. The catalog renders as `&lt;available_skills&gt;` XML for Anthropic models and markdown for others; portable and hosted (native) skills refuse to combine in one call.

Core `@tanstack/ai` now exports `SkillLimitError`. The native factories throw it (or add validation): `codeExecutionTool` (`@tanstack/ai-anthropic`) frames its 8-skill cap, and `shellTool` (`@tanstack/openai-base`) now validates `skill_id` format instead of nothing. `@tanstack/ai-sandbox` reuses the shared skill-directory walk from `@tanstack/ai-skills`.
