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 | $0.00035 | $0.00660 |
| Opus 5.5 | $0.00014 | $0.00264 |
| Sonnet 5.5 | $0.00007 | $0.00132 |
| Haiku 4.5 | $0.00003 | $0.00066 |
Grade A, and why
react-native-app 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

React Native App Development
Table of Contents
Overview
Create robust cross-platform mobile applications using React Native with modern development patterns including navigation, state management, API integration, and native module handling.
When to Use
- Building iOS and Android apps from single codebase
- Rapid prototyping for mobile platforms
- Leveraging web development skills for mobile
- Sharing code between React Native and React Web
- Integrating with native modules and APIs
Quick Start
Minimal working example:
// Navigation with React Navigation
import React from "react";
import { NavigationContainer } from "@react-navigation/native";
import { createNativeStackNavigator } from "@react-navigation/native-stack";
import { createBottomTabNavigator } from "@react-navigation/bottom-tabs";
import { Ionicons } from "@expo/vector-icons";
const Stack = createNativeStackNavigator();
const Tab = createBottomTabNavigator();
function HomeStack() {
return (
<Stack.Navigator
screenOptions={{
headerStyle: { backgroundColor: "#6200ee" },
headerTintColor: "#fff",
headerTitleStyle: { fontWeight: "bold" },
}}
>
<Stack.Screen
name="Home"
component={HomeScreen}
options={{ title: "Home Feed" }}
/>
<Stack.Screen name="Details" component={DetailsScreen} />
// ... (see reference guides for full implementation)

What ships with it
5 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.

react-native-app is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (376 stars, last pushed 8mo ago), licensed MIT. It adds 35 tokens to every session and 660 once invoked, about $0.0001 per session on Opus 5.5. 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.
