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 | $0.00065 | $0.01639 |
| Opus 5.5 | $0.00026 | $0.00656 |
| Sonnet 5.5 | $0.00013 | $0.00328 |
| Haiku 4.5 | $0.00006 | $0.00164 |
Grade A, and why
tanstack-router 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 2mo 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.

TanStack Router
Version: @tanstack/react-[email protected] Requires: React 18.0+, TypeScript 5.0+, Vite (recommended)
Quick Setup
npm install @tanstack/react-router @tanstack/react-router-devtools
npm install -D @tanstack/router-plugin
Vite Plugin
// vite.config.ts
import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import { tanstackRouter } from '@tanstack/router-plugin/vite'
export default defineConfig({
plugins: [tanstackRouter(), react()],
})
Root Route
// src/routes/__root.tsx
import { createRootRoute, Outlet } from '@tanstack/react-router'
import { TanStackRouterDevtools } from '@tanstack/react-router-devtools'
export const Route = createRootRoute({
component: () => (
<>
<Outlet />
<TanStackRouterDevtools />
</>
),
})
Unified Devtools (Recommended with Multiple TanStack Libraries)
If using Router + Query (or other TanStack libraries), use the unified TanStackDevtools shell instead of individual devtools components:
npm install -D @tanstack/react-devtools
// src/routes/__root.tsx
import { createRootRoute, Outlet } from '@tanstack/react-router'
import { TanStackRouterDevtoolsPanel } from '@tanstack/react-router-devtools'
import { TanStackDevtools } from '@tanstack/react-devtools'
export const Route = createRootRoute({
component: () => (
<>
<Outlet />
<TanStackDevtools
config={{ position: 'bottom-right' }}
plugins={[
{ name: 'TanStack Router', render: <TanStackRouterDevtoolsPanel /> },
// Add more plugins: Query, etc.
]}
/>
</>
),
})
Use *Panel variants (TanStackRouterDevtoolsPanel, ReactQueryDevtoolsPanel) when embedding inside TanStackDevtools.
Router Creation & Type Registration
// src/router.tsx
import { createRouter } from '@tanstack/react-router'
import { routeTree } from './routeTree.gen'
export const router = createRouter({ routeTree })
// Register router type for global inference
declare module '@tanstack/react-router' {
interface Register {
router: typeof router
}
}

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.
