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

claude-code-app-studio CLAUDE.md 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 3d 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.

Claude Code App Studios -- Mobile App Studio Agent Architecture

A coordinated team of 54 Claude Code subagents that build, ship, and operate mobile apps end to end. Each agent owns a narrow slice of the lifecycle so that responsibility, expertise, and review checkpoints stay separated and observable.

Technology Stack

  • Framework: [CHOOSE: React Native + TypeScript / Flutter + Dart / Native iOS (Swift) / Native Android (Kotlin)]
  • Language: [CHOOSE: TypeScript / Dart / Swift / Kotlin]
  • Target Platforms: iOS 17+ and Android 13+ unless otherwise scoped
  • Source Control: Git, trunk-based with short-lived feature branches
  • Build & Distribution: [SPECIFY after framework is chosen — Fastlane, EAS, Xcode Cloud, Play Console, App Store Connect]
  • Backend: [SPECIFY — REST/GraphQL service, Firebase, Supabase, custom]

Note: Framework specialists exist for each of the four supported stacks with dedicated language and UI sub-specialists. Use the set that matches the framework you have chosen. Never mix specialists across stacks for the same surface area without an ADR.

Domain Glossary

The repository uses mobile-product vocabulary throughout. When reading legacy notes that reference any of these terms, translate as follows:

Term in this template Means
framework The chosen mobile stack (RN, Flutter, iOS native, Android native)
app The product itself
user The person using the app
screen / flow / journey A view, a multi-step task, the longitudinal path
PRD Product requirements document — the single source of truth per feature
user test / beta Pre-release validation with real users (TestFlight, Play internal track)
monetization / pricing Revenue model (IAP, subscriptions, ads, paid app)
animations / transitions Motion design including micro-interactions
haptics, sound, push notifications Sensory and out-of-app communication channels
backend integration / sync API consumption, offline cache, conflict resolution
mobile security Cert pinning, RASP, jailbreak/root detection, secure storage
flow-designer / journey-designer The agent that owns end-to-end task design
product-director Final authority on product direction
visual-design-director Owns the visual system and UI design language
motion-director Owns motion, haptics, and sonic identity

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.
