TanStack AI is a TypeScript SDK for building applications that stream AI responses, call tools, run agents, produce structured output, and handle multimodal or realtime interactions. Developers use it across frameworks and AI providers through shared typed interfaces and provider adapters. The catalogue entries are add-ons for working with this SDK.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.07503 |
| Opus 5.5 | $0.00026 | $0.03001 |
| Sonnet 5.5 | $0.00013 | $0.01501 |
| Haiku 4.5 | $0.00006 | $0.00750 |
Grade A, and why
remix scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Prefer server and router tests first. Drive the app with `router.fetch(new Request(...))` and assert on the returned `Response` Copies of this mod

How it starts
The opening of the file, as written. The whole thing — 453 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build a Remix App
Use this skill for end-to-end Remix app work. This skill helps you choose the right layer first, reach for the right package, and avoid the most common Remix-specific mistakes.
Full Package Documentation
This skill is the quick guide. When you need fuller API documentation, examples, or package-specific details for a remix/* subpath, first look for a README next to the relevant generated source file in the published remix package: node_modules/remix/src/<subpath>/README.md. These published README files are generated mirrors; in the Remix source repository, the canonical README lives in the owning packages/* package and the packages/remix/src/**/README.md mirrors are intentionally ignored. If that README does not exist, look for the nearest parent README because some subpaths share their parent package documentation.
Examples:
remix/router->node_modules/remix/src/fetch-router/README.mdremix/ui/button->node_modules/remix/src/ui/button/README.md
What Remix Is
Remix 3 is a server-first web framework built on Web APIs such as Request, Response, URL, and FormData. All packages ship from a single npm package, remix, and are imported via subpath. There is no top-level remix import.
A Remix app has four main pieces:
- Routes in
app/routes.tsdefine the typed URL contract and powerhref()generation. - Controllers in
app/actionsimplement that contract and returnResponseobjects. - Middleware composes request lifecycle behavior and populates typed context via
context.set(Key, value). - Components render UI with
remix/ui. This is not React. A component receives ahandle, reads current props fromhandle.props, and returns a zero-argument render function.
When To Use This Skill
Use this skill for:
- new features or refactors that touch routing, controllers, middleware, data, auth, sessions, UI, or tests
- reviewing Remix app code for correctness, architecture, or framework usage
- answering "how should this be structured in Remix?" questions
- finding the right package, reference doc, or default pattern for a task

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

remix is a skill published in the GitHub repository TanStack/ai (3,245 stars, last pushed yesterday), licensed MIT. It adds 65 tokens to every session and 7,503 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
