- [TypeScript Advanced Types](https://labs.pho.chat/en/skills/wshobson-agents/languages/typescript-advanced-types.md): Master TypeScript's advanced type system including generics, conditional types, mapped types, template literals, and utility types for building type-safe applications. Use when implementing complex…
- [Go Concurrency Patterns](https://labs.pho.chat/en/skills/wshobson-agents/languages/go-concurrency-patterns.md): Master Go concurrency with goroutines, channels, sync primitives, and context. Use when building concurrent Go applications, implementing worker pools, or debugging race conditions.
- [Memory Safety Patterns](https://labs.pho.chat/en/skills/wshobson-agents/languages/memory-safety-patterns.md): Implement memory-safe programming with RAII, ownership, smart pointers, and resource management across Rust, C++, and C. Use when writing safe systems code, managing resources, or preventing memory…
- [Rust Async Patterns](https://labs.pho.chat/en/skills/wshobson-agents/languages/rust-async-patterns.md): Master Rust async programming with Tokio, async traits, error handling, and concurrent patterns. Use when building async Rust applications, implementing concurrent systems, or debugging async code.
