The swift-concurrency skill helps you review async/await refactors, actor isolation, Sendable issues, task structure, and Swift 6 migration with less guesswork. Use it for practical code editing when compiler warnings, data races, or isolation boundaries matter, and when you need a swift-concurrency guide grounded in repo-backed conventions.

The swift-library-design skill helps you design Swift libraries and frameworks with stronger public APIs, compile-time safety, and performance-aware defaults. Use it for protocol-oriented architecture, associated types, result builders, DSLs, noncopyable types, and progressive disclosure when building reusable Swift packages or SDK-style modules.

The postgres-nio skill helps you use PostgreSQL from Swift with async/await, connection pooling, prepared statements, and type-safe queries. It is a strong fit for Backend Development teams building Swift services that need practical postgres-nio usage, not generic SQL theory.

The swift skill helps you write better Swift code with less guesswork. Use it for Swift configuration, logging, observability, testing, cross-platform patterns, API design, access control, and memory-safety features. It is especially useful for Swift for Backend Development, where practical swift usage, install guidance, and repo-aware implementation details matter.

The hummingbird skill provides practical guidance for Hummingbird 2, a lightweight Swift HTTP server framework. Use it to install, set up, and use hummingbird for Backend Development, including routing, middleware, auth, websockets, and Fluent integration when you need a focused hummingbird guide.

hig-technologies is an Apple HIG guide for designing and evaluating Apple technology integrations like Siri, Apple Pay, HealthKit, HomeKit, ARKit, iCloud, Sign in with Apple, SharePlay, CarPlay, VoiceOver, Maps, NFC, and Wallet. Use this hig-technologies skill to shape native behavior, privacy, consent, recovery, and user expectations before implementation.

wendy-lite is a skill for building WebAssembly apps on Wendy Lite firmware for ESP32-C6. Use it to write C, Rust, Swift, Zig, TypeScript, or WAT modules that match the WAMR runtime, host imports, callback flow, and flash-loaded device lifecycle. It is a practical wendy-lite guide for firmware-adjacent app development.

wendy-swift is a curated Swift package discovery skill for WendyOS and Linux backend development. Use the wendy-swift skill to choose a Swift library, compare ecosystem options, and find packages that fit Linux/ARM64/AMD64 deployment constraints with less guesswork.

wendy skill guide for building, deploying, and managing apps on WendyOS edge devices. Use it for wendy install, wendy usage, device discovery, Swift app deployment, remote debugging on ARM64, and workflows for NVIDIA Jetson or Raspberry Pi 4/5. Best when you need structured, JSON-first CLI steps instead of guesswork.

swift-valkey helps Swift backend developers use Valkey and Redis with async/await, cluster routing, and pub/sub. It is a practical swift-valkey guide for cache, queue, and session workflows, with install and usage notes grounded in the repo’s SKILL.md and typed command patterns.

swift-nio is a skill for SwiftNIO backend development, covering servers, clients, pipelines, buffers, codecs, and event-loop-safe async code.
