remix

remix is a skill for Claude Code, Codex from TanStack/ai. It costs 65 tokens per session (7,503 once invoked), scanned A, original, MIT.

A web framework for building Remix 3 applications. It organizes server code, pages, routes, data loading, forms, authentication, and browser interactions.

In plain words
What is it for?
Use it to create web pages, API handlers, login flows, file uploads, sessions, navigation, and automated tests.
Why use it?
It gives developers a consistent structure for applications that run work on the server and in the browser. This reduces confusion about where requests, data, and interface code belong.

About the project

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.

Token cost

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.

Security

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 2d 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.

Makes network callslowCapability

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`

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.md
  • remix/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.ts define the typed URL contract and power href() generation.
  • Controllers in app/actions implement that contract and return Response objects.
  • 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 a handle, reads current props from handle.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

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 (3,067 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. 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.
