This Skill provides comprehensive Rust development guidelines derived from real-world code reviews, helping teams write safer, more idiomatic, and high-performance Rust code while avoiding common pitfalls.
Start with the Quick Reference (quick-reference.md) and read Error Handling Deep Dive, File I/O Deep Dive, and Type Safety Deep Dive to establish a solid baseline.

Rust safety relies on ownership, borrowing, and type systems to prevent memory errors at compile time. This Skill delivers 20+ lessons on error handling, file I/O safety, and type safety patterns derived from real-world code reviews, helping you write idiomatic code that compiles safely.
Error handling in Rust uses Result types and proper propagation to distinguish recoverable errors from unrecoverable ones. The Error Handling Deep Dive covers validation, error propagation, and safe API design to ensure your code fails predictably and safely.
Performance optimization in Rust focuses on ownership patterns, avoiding unnecessary allocations, and leveraging the type system. The Skill includes practical deep dives on performance optimization techniques that maintain safety while achieving speed.
Rust's type system prevents many file I/O bugs, but safe handling requires proper error handling and resource management. The File I/O Deep Dive covers resource cleanup, error cases, and patterns for safe file operations in production CLI tools and hooks.
PR reviews should validate ownership correctness, error handling patterns, type safety, and idiomatic code structure. The Quick Reference and deep dives provide 20+ checks for ensuring Rust changes are safe, performant, and follow team standards.
Rust's ownership system eliminates entire categories of memory errors—null pointers, use-after-free, data races—at compile time. This Skill teaches the patterns and guardrails that make Rust fundamentally safer than C or C++ for systems code.
