rust-expert

This skill should be used when the user is writing, reviewing, debugging, or architecting Rust code. Detects edition and toolchain from the project. Provides expert critique covering ownership, error handling, unsafe review, async correctness, trait design, type system patterns, performance, SOLID principles, and Cargo/workspace practices. Use when the user asks "critique my Rust code", "review this module", "fix borrow checker error", "is this unsafe sound", "design error types", "optimize this function", "review async code", "structure my workspace", "why is the borrow checker complaining", "help with lifetimes", "make this more idiomatic", or "review my Cargo.toml".
