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.

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 | $0.00030 | $0.00537 |
| Opus 5.5 | $0.00012 | $0.00215 |
| Sonnet 5.5 | $0.00006 | $0.00107 |
| Haiku 4.5 | $0.00003 | $0.00054 |
Grade A, and why
frontend-routing 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.

Frontend Routing
Table of Contents
Overview
Implement client-side routing with navigation, lazy loading, protected routes, and state management for multi-page single-page applications.
When to Use
- Multi-page navigation
- URL-based state management
- Protected/guarded routes
- Lazy loading of components
- Query parameter handling
Quick Start
Minimal working example:
// App.tsx
import { BrowserRouter, Routes, Route, Navigate } from 'react-router-dom';
import { Layout } from './components/Layout';
import { Home } from './pages/Home';
import { NotFound } from './pages/NotFound';
import { useAuth } from './hooks/useAuth';
import React from 'react';
// Lazy loaded components
const Dashboard = React.lazy(() => import('./pages/Dashboard'));
const UserProfile = React.lazy(() => import('./pages/UserProfile'));
const Settings = React.lazy(() => import('./pages/Settings'));
// Protected route wrapper
const ProtectedRoute: React.FC<{ children: React.ReactNode }> = ({ children }) => {
const { isAuthenticated } = useAuth();
if (!isAuthenticated) {
return <Navigate to="/login" replace />;
}
return <>{children}</>;
};
export const App: React.FC = () => {
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Follow established patterns and conventions
- Write clean, maintainable code
- Add appropriate documentation
- Test thoroughly before deploying
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

frontend-routing is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (376 stars, last pushed 8mo ago), licensed MIT. It adds 30 tokens to every session and 537 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
