everything-react-native-expo: Skill for Claude Code

.claude/skills/erne-navigate/SKILL.md

erne-navigate is a skill for Claude Code from JubaKitiashvili/everything-react-native-expo. It costs 14 tokens per session (534 once invoked), scanned A, original, MIT.

A navigation-planning skill for React Native and Expo apps. It maps screens, navigation groups such as tabs and login flows, and the file-based routes used by Expo Router.

In plain words
What is it for?
Planning tabs, drawers, stacks, login flows, detail pages, modals, and the corresponding Expo Router folders and files.
Why use it?
It turns a list of screens into a clear structure before implementation, reducing confusing navigation and misplaced route files.

Token cost

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.

Security

Grade A, and why

erne-navigate 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 12d 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.

/erne-navigate — Navigation Design

You are executing the /erne-navigate command. Use the architect agent to design navigation structure.

Process

  1. Map the screens — List all screens and their relationships
  2. Design the hierarchy — Determine navigation stacks, tabs, drawers
  3. Plan Expo Router file structure — Map screens to file-based routes

Output: Expo Router File Structure

app/
  _layout.tsx              # Root Stack
  index.tsx                # Redirect to (tabs)
  +not-found.tsx           # 404 screen
  (tabs)/
    _layout.tsx            # Tab navigator
    index.tsx              # Home tab
    search.tsx             # Search tab
    profile.tsx            # Profile tab
  (auth)/
    _layout.tsx            # Auth stack (no tabs)
    login.tsx
    register.tsx
    forgot-password.tsx
  [entity]/
    _layout.tsx            # Entity detail stack
    [id].tsx               # Entity detail screen
    [id]/edit.tsx           # Edit screen
  modal/
    _layout.tsx            # Modal group
    settings.tsx           # Settings modal
    create-post.tsx        # Create post modal
  1. Define navigation patterns:

    • Tab-to-detail: How tabs navigate to detail screens
    • Auth flow: How unauthenticated users are redirected
    • Deep linking: URL scheme mapping
    • Modal presentation: Full-screen vs bottom sheet
  2. Generate layout files — Create _layout.tsx files with proper configuration:

// app/(tabs)/_layout.tsx
import { Tabs } from 'expo-router';

export default function TabLayout() {
  return (
    <Tabs screenOptions={{ tabBarActiveTintColor: '#007AFF' }}>
      <Tabs.Screen name="index" options={{ title: 'Home', tabBarIcon: ... }} />
      <Tabs.Screen name="search" options={{ title: 'Search', tabBarIcon: ... }} />
      <Tabs.Screen name="profile" options={{ title: 'Profile', tabBarIcon: ... }} />
    </Tabs>
  );
}

Notes

  • Reference rules/common/navigation.md for conventions
  • Consider deep link testing: npx uri-scheme open [url] --ios
  • Include typed route definitions

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.
