Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00062 | $0.05809 |
| Opus 5 | $0.00031 | $0.02905 |
| Sonnet 5 | $0.00012 | $0.01162 |
| Haiku 4.5 | $0.00006 | $0.00581 |
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 5d 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 This is a copy
86% identical to remix — 523 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 502 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. It should help the agent choose the right layer first, reach for the right package, and avoid the most common Remix-specific mistakes.
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 and actions implement that contract and return
Responseobjects. - 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 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
Load Only The References You Need
Classify the task first, then load the smallest useful reference set. Each reference file starts with a "What This Covers" section that lists the topics inside it — read that first to confirm the file is relevant before reading the rest.
Use the table below to find candidates. Loading more than two or three files at once is usually a sign that the task hasn't been narrowed enough yet.
| Task involves... | Start with |
|---|---|
| Defining URLs, writing controllers and actions, returning responses | references/routing-and-controllers.md |
| Composing the request lifecycle, ordering middleware, bridging to a server | references/middleware-and-server.md |
| Compiling and serving browser modules, asset URL namespaces, preloads | references/assets-and-browser-modules.md |
| Parsing input, validating with schemas, defining tables, querying, migrations | references/data-and-validation.md |
| Per-browser state, login flows, route protection, identity | references/auth-and-sessions.md |
Component setup, state, lifecycle, updates, queueTask, context |
references/component-model.md |
| Event handlers, styles, refs, click/key behavior, simple animations | references/mixins-styling-events.md |
clientEntry, run, <Frame>, navigation, <head> |

| Router tests, component tests, test isolation | references/testing-patterns.md |

| Authoring custom reusable mixins | references/create-mixins.md |

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 pi0/vite-plugin-remix3 (23 stars, last pushed 4mo ago), licensed MIT. It adds 62 tokens to every session and 5,809 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 86% identical to remix, differing in 523 lines, and is treated as a copy.
