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 | $0.00015 | $0.00597 |
| Opus 5 | $0.00008 | $0.00298 |
| Sonnet 5 | $0.00003 | $0.00119 |
| Haiku 4.5 | $0.00002 | $0.00060 |
Grade A, and why
cross-platform 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 6d 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.

Cross-Platform Development Guidelines
React Native Development
- Use React Native 0.72+ with modern features
- Use functional components with Hooks
- Use TypeScript for type safety
- Implement proper navigation with React Navigation
- Use Redux, MobX, or Zustand for state management
- Follow React Native best practices
- Use Expo for rapid prototyping when appropriate
Flutter Development
- Use Flutter 3.16+ with Dart 3.0+
- Use StatefulWidget and StatelessWidget appropriately
- Use Provider, Riverpod, or Bloc for state management
- Implement proper navigation with Navigator 2.0
- Follow Flutter best practices and widget composition
- Use Flutter DevTools for debugging
- Leverage pub.dev for packages
Cross-Platform Architecture Patterns
- MVVM: Use with reactive state management
- BLoC Pattern: Use with Flutter for business logic
- Clean Architecture: Separate layers properly
- Repository Pattern: Abstract data sources
- Implement proper dependency injection
- Separate business logic from UI code
- Use shared code for business logic
Native Module Integration
- Create native modules for platform-specific features
- Use React Native Native Modules for iOS/Android
- Use Flutter Platform Channels for native communication
- Implement proper error handling across platforms
- Maintain consistent APIs across platforms
- Use platform-specific optimizations when needed
- Document native module interfaces
Cross-Platform State Management
- React Native: Redux, MobX, Zustand, Context API
- Flutter: Provider, Riverpod, Bloc, GetX
- Implement proper state persistence
- Use immutable state patterns
- Handle async operations properly
- Use middleware for side effects
- Implement proper state hydration
Cross-Platform Navigation
- React Native: React Navigation (Stack, Tab, Drawer)
- Flutter: Navigator 2.0, GoRouter, AutoRoute
- Implement deep linking properly
- Handle back button behavior correctly
- Use type-safe navigation when possible
- Implement proper route guards
- Handle navigation state persistence
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.

cross-platform is a skill published in the GitHub repository MonumentalSystems/Atlas-Agent-Teams (21 stars, last pushed 29d ago), licensed MIT. It adds 15 tokens to every session and 597 once invoked, about $0.0001 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 2026-09-03.
