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 | $0.01546 | $0.01546 |
| Opus 5.5 | $0.00618 | $0.00618 |
| Sonnet 5.5 | $0.00309 | $0.00309 |
| Haiku 4.5 | $0.00155 | $0.00155 |
Grade A, and why
project 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.

Project Rules
This is a production-grade React Native Expo template. All rules below are mandatory.
See CONVENTIONS.md for detailed conventions and docs/AI-GUIDE.md for patterns and recipes.
Stack Summary
- React Native 0.83.2 + Expo SDK 55, expo-router (file-based)
- TypeScript 5.9 strict, path aliases:
@/*=src/*,~/*=app/* - Styling: react-native-unistyles 3.x (NOT react-native StyleSheet)
- Server state: @tanstack/react-query
- Client state: Zustand (auth via
useAuthStore) - Forms: react-hook-form +
zod/v4 - Storage: react-native-mmkv via
@/utils/storage - i18n: react-i18next, EN + AR (RTL)
- HTTP: Axios via
@/services/api(auto-attaches Bearer token)
Non-Negotiable Rules
Styling
// Import ALWAYS from react-native-unistyles
import { StyleSheet } from 'react-native-unistyles';
// ALWAYS use theme callback
const styles = StyleSheet.create((theme) => ({
container: {
padding: theme.metrics.spacing.p16, // NOT padding: 16
backgroundColor: theme.colors.background.surface, // NOT '#FFFFFF'
borderRadius: theme.metrics.borderRadius.md,
},
}));
// NEVER inline styles
// WRONG: <View style={{ padding: 16, backgroundColor: '#fff' }}>
// RIGHT: <View style={styles.container}>
Components
// Always use project Text, not React Native Text
import { Text } from '@/common/components/Text';
<Text variant="h1">{t('home.title')}</Text>
// Always use ScreenContainer as screen root
import { ScreenContainer } from '@/common/components/ScreenContainer';
export default function MyScreen() {
return <ScreenContainer scrollable>{/* content */}</ScreenContainer>;
}
// Import from barrel, not implementation
import { Button } from '@/common/components/Button'; // CORRECT
import { Button } from '@/common/components/Button/Button'; // WRONG
i18n - Every String Must Be Translated
const { t } = useTranslation();
<Text>{t('home.welcome')}</Text> // CORRECT
<Text>Welcome</Text> // WRONG - hardcoded
// Update BOTH files when adding text:
// src/i18n/locales/en.json
// src/i18n/locales/ar.json
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.
