+
+# Mobile Best Practices
+
+A searchable database of 2,461 curated mobile development guidelines for Android, iOS, Flutter, and React Native. Uses BM25 ranking with fuzzy search across 16 CSV databases.
+
+## When to Use This Skill
+
+- Building or reviewing Android apps (Jetpack Compose or XML)
+- Building or reviewing iOS apps (SwiftUI or UIKit)
+- Flutter or React Native development
+- Security audits mapped to OWASP Mobile Top 10
+- Performance optimization and ANR/crash prevention
+- Architecture pattern selection (MVVM, MVI, Clean Architecture, etc.)
+- Choosing libraries and Gradle dependencies
+- Code review against known anti-patterns
+
+## Installation
+
+```bash
+npx mobile-best-practices install
+```
+
+Or manually copy to `~/.claude/skills/mobile-best-practices/`.
+
+## Search
+
+```bash
+python3 search.py "<query>" --domain <domain> -n <max_results>
+```
+
+### Domains
+
+| Domain | Description |
+|--------|-------------|
+| `architecture` | MVVM, MVI, Clean Architecture, Redux |
+| `design-patterns` | Repository, Factory, Observer, Singleton |
+| `ui` | Compose, SwiftUI, UIKit, Flutter widgets |
+| `anti-patterns` | Common mistakes and how to fix them |
+| `security` | OWASP Mobile Top 10, encryption, storage |
+| `performance` | Recomposition, memory, rendering, battery |
+| `testing` | Unit, UI, integration, snapshot tests |
+| `libraries` | Recommended third-party libraries |
+| `snippets` | Copy-paste code examples |
+| `gradle` | Dependency declarations with versions |
+
+### Examples
+
+```bash
+# Find Jetpack Compose performance tips
+python3 search.py "jetpack compose recomposition" --domain performance
+
+# Find security issues with API keys
+python3 search.py "API key storage" --domain security
+
+# Find Flutter state management patterns
+python3 search.py "flutter state management" --domain architecture
+
+# Find React Native anti-patterns
+python3 search.py "react native memory leak" --domain anti-patterns
+
+# Search across all domains
+python3 search.py "biometric authentication" --all-domains
+```
