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 | $0.00016 | $0.00718 |
| Opus 5 | $0.00008 | $0.00359 |
| Sonnet 5 | $0.00003 | $0.00144 |
| Haiku 4.5 | $0.00002 | $0.00072 |
Grade A, and why
netlify-frameworks-tanstack scanned grade A with 0 findings 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TanStack Start on Netlify
Setup
Check current versions before pinning. Knowledge cutoffs lag behind npm, and guessing a version tends to fail (
npm installrejects it, or worse, installs something incompatible). Before pinning@netlify/vite-plugin-tanstack-start,@tanstack/react-start,vite, or any other package inpackage.json, runnpm view <pkg> versionto get the currentlatest. Or omit explicit pins and letnpm installpick them up. If that check itself fails (no network, registry unreachable), still don't fall back to a guessed exact pin — install without a version (or with@latest) and tell the user live verification wasn't possible so they should confirm the installed versions. Never present an unverifiedx.y.zas the current release.
TanStack Start uses the @netlify/vite-plugin-tanstack-start plugin for deployment.
npm install -D @netlify/vite-plugin-tanstack-start
Register it in vite.config.ts alongside the TanStack Start and React plugins:
// vite.config.ts
import { defineConfig } from "vite";
import { tanstackStart } from "@tanstack/react-start/plugin/vite";
import netlify from "@netlify/vite-plugin-tanstack-start";
import viteReact from "@vitejs/plugin-react";
export default defineConfig({
plugins: [tanstackStart(), netlify(), viteReact()],
});
TanStack Start < 1.132.0: the standalone plugin isn't available. Instead pass the
target: 'netlify'option totanstackStart()invite.config.ts(tanstackStart({ target: 'netlify' })) and don't install@netlify/vite-plugin-tanstack-start.
Netlify CLI deploys: deploying with the Netlify CLI requires netlify-cli ≥ 17.31.
What the Plugin Does
- Deploys SSR, Server Routes, Server Functions, and middleware to Netlify Functions
- Provides full local Netlify platform emulation in
vite dev(nonetlify devneeded) - Maps TanStack Start's file-based routing to Netlify's infrastructure
Server Functions
TanStack Start uses createServerFn for server-side logic. These are automatically handled by the Netlify plugin — no raw Netlify Functions needed:
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.

netlify-frameworks-tanstack is a cursor rule published in the GitHub repository netlify/context-and-tools (36 stars, last pushed 5d ago), licensed MIT. It adds 16 tokens to every session and 718 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
