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 | $0.00054 | $0.03502 |
| Opus 5 | $0.00027 | $0.01751 |
| Sonnet 5 | $0.00011 | $0.00700 |
| Haiku 4.5 | $0.00005 | $0.00350 |
Grade A, and why
nylo-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 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.

Nylo Routing
Overview
Nylo v7 routing is defined in lib/routes/router.dart using nyRoutes(). Routes map URL paths to page widgets, support guards for access control, and integrate with NavigationHub for tab-based and journey navigation layouts.
When to Use
- Defining or modifying app routes
- Navigating between pages (push, replace, pop)
- Passing data, query parameters, or path parameters between pages
- Protecting routes with guards (auth, roles, subscriptions)
- Setting up bottom navigation, top tabs, or onboarding journeys
- Configuring page transition animations
- Implementing deep linking
- When NOT to use: For state management within a single page, use NyState/NyPage instead
Quick Reference
| Action | Code |
|---|---|
| Define route | router.add(MyPage.path) |
| Set initial route | router.add(MyPage.path).initialRoute() |
| Navigate to page | routeTo(MyPage.path) |
| Navigate with data | routeTo(MyPage.path, data: {"key": "val"}) |
| Navigate with query params | routeTo(MyPage.path, queryParameters: {"tab": "1"}) |
| Navigate with path params | routeTo(MyPage.path.withParams({"id": 7})) |
| Go back | pop() |
| Go back with result | pop(result: {"status": "done"}) |
| Replace current route | routeTo(MyPage.path, navigationType: NavigationType.pushReplace) |
| Clear stack and navigate | routeTo(MyPage.path, navigationType: NavigationType.pushAndForgetAll) |
| Navigate to initial route | routeToInitial() |
| Navigate to auth route | routeToAuthenticatedRoute() |
| Add route guard | router.add(MyPage.path, routeGuards: [MyGuard()]) |
| Create page (CLI) | metro make:page profile_page |
| Create guard (CLI) | metro make:route_guard auth |
| Create nav hub (CLI) | metro make:navigation_hub base |
Route Definitions
Routes live in lib/routes/router.dart:
appRouter() => nyRoutes((router) {
router.add(HomePage.path).initialRoute();
router.add(ProfilePage.path);
router.add(SettingsPage.path);
});
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.

nylo-routing is a skill published in the GitHub repository nylo-core/claude-code (4 stars, last pushed 4mo ago), licensed MIT. It adds 54 tokens to every session and 3,502 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
