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

mobile 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 today.

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

Mobile Development Standards

Variant-specific stacks live in .agents/skills/oma-mobile/variants/{flutter,react-native,swift-ios}/. React Native sources (.ts/.tsx) are not matched by this rule's glob — for RN work, read the react-native variant directly. Kotlin-native (Compose) is not a supported variant; .kt files here are Flutter/RN Android host code only.

Core Rules

  1. Clean Architecture: domain -> data -> presentation (Swift native: App/Core/Features/Shared)
  2. State Management: the variant's solution — Flutter: Riverpod/Bloc; React Native: Zustand + TanStack Query; Swift: @MainActor @Observable. No raw setState/ad-hoc state for complex logic
  3. Design Guidelines: Material Design 3 (Android) + iOS HIG (iOS)
  4. Resource Cleanup: dispose controllers / cancel structured tasks; Swift: .task {} auto-cancel, never deinit
  5. Networking: transport client with interceptors (Flutter: Dio; RN: axios behind TanStack Query hooks; Swift: swift-openapi-generator Client) + mandatory repository-layer response cache; handle offline gracefully
  6. Secrets: secure storage only (flutter_secure_storage / Keychain / react-native-keychain) — never plain prefs or MMKV
  7. Performance: 60fps target; test on both platforms
  8. E2E Testing: Maestro (Flutter/RN) or XCUITest (Swift native) for critical user flows

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.
