AI agent steering for Apple (Swift 6.4 / SwiftUI / visionOS / Foundation Models) and Android (Kotlin / Compose / Gradle / Gemini Nano). Rules + skills + MCP for code, a11y, localization, TestFlight/Play. One install.sh detects your stack, installs the right per-platform rules, and keeps them current for Claude/Copilot/Cursor/Gemini/Codex/Kiro.
