Enables AI agents to execute x402 payments with per-task budgets, spending controls, and non-custodial wallets via MCP tools. Use when agents pay for APIs, services, or other agents.
Compares coding agents like Claude Code and Aider on custom YAML-defined codebase tasks using git worktrees, measuring pass rate, cost, time, and consistency.
Unified skill for cross-platform (Expo/React Native) and platform-native (iOS/Swift, Android/Kotlin) mobile development. Covers UI, navigation, data, deployment, and performance across all mobile platforms.

Building a mobile app?
Cross-platform (iOS + Android)?
YES -> Expo / React Native (default choice)
NO -> Which platform?
iOS only -> Swift + SwiftUI (iOS 17+: SwiftData + @Observable)
Android only -> Kotlin + Jetpack Compose + Hilt
