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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00291 |
| Opus 5 | $0.00000 | $0.00146 |
| Sonnet 5 | $0.00000 | $0.00058 |
| Haiku 4.5 | $0.00000 | $0.00029 |
Grade A, and why
navigation-patterns 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.
What it actually says
Skill: Navigation Patterns (React Navigation)
When to load
When designing app navigation, implementing deep linking, or handling auth flows.
Architecture
const RootNavigator = () => {
const { isAuthenticated, isLoading } = useAuth();
if (isLoading) return <SplashScreen />;
return (
<NavigationContainer linking={linking} ref={navigationRef}>
{isAuthenticated ? <AppNavigator /> : <AuthNavigator />}
</NavigationContainer>
);
};
const AppNavigator = () => (
<BottomTabs.Navigator>
<BottomTabs.Screen name="HomeTab" component={HomeStackNavigator} />
<BottomTabs.Screen name="ProfileTab" component={ProfileStackNavigator} />
</BottomTabs.Navigator>
);
Deep Link Validation
export const linking: LinkingOptions<RootStackParamList> = {
prefixes: ['myapp://', 'https://myapp.com'],
config: {
screens: {
HomeTab: {
screens: {
OrderDetail: {
path: 'orders/:orderId',
parse: { orderId: String },
// Sanitize: only alphanumeric and dashes
stringify: { orderId: (id) => id.replace(/[^a-zA-Z0-9-]/g, '') },
},
},
},
},
},
};
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.

navigation-patterns is a skill published in the GitHub repository sawrus/agent-guides (17 stars, last pushed 5d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 291 tokens. 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.
