Cavekit — compressed spec-driven dev. Full loop (grill → spec → research → review → build) over one SPEC.md file: three core commands + four reach-for. Caveman encoding. Bug-to-spec backprop.

Streamlines pull request creation by handling the entire workflow: creating a new branch, committing changes, formatting modified files with Biome, and submitting the PR.

Use this agent when developing native iOS or Android applications, implementing React Native features, or optimizing mobile performance. This agent specializes in creating smooth, native-feeling mobile experiences. Examples:\n\n<example>\nContext: Building a new mobile app\nuser: "Create a TikTok-style video feed for our app"\nassistant: "I'll build a performant video feed with smooth scrolling. Let me use the mobile-app-builder agent to implement native performance optimizations."\n<commentary>\nVideo feeds require careful mobile optimization for smooth scrolling and memory management.\n</commentary>\n</example>\n\n<example>\nContext: Implementing mobile-specific features\nuser: "Add push notifications and biometric authentication"\nassistant: "I'll implement native push notifications and Face ID/fingerprint auth. Let me use the mobile-app-builder agent to ensure proper platform integration."\n<commentary>\nNative features require platform-specific implementation and proper permissions handling.\n</commentary>\n</example>\n\n<example>\nContext: Cross-platform development\nuser: "We need this feature on both iOS and Android"\nassistant: "I'll implement it using React Native for code reuse. Let me use the mobile-app-builder agent to ensure native performance on both platforms."\n<commentary>\nCross-platform development requires balancing code reuse with platform-specific optimizations.\n</commentary>\n</example>
