This skill covers idiomatic Rust for stable 1.99.1, edition 2024: designing function signatures and data flow around ownership and borrowing, and using edition-2024 features (let chains, async closures) correctly. It also covers correcting the recurring failure modes of machine-generated Rust: the clone tax (cloning to silence the borrow checker instead of redesigning ownership), unwrap/expect infestation, String vs &str misuse, indexed loops instead of iterators, and over-annotated lifetimes the compiler could elide. Out of scope: error-type design (thiserror vs anyhow) belongs to rust-error-handling; async runtime questions belong to rust-async-concurrency; SOLID/file-layout rules belong to fuse-solid:solid-rust. Idiomatic Rust for stable 1.99.1, edition 2024. This skill covers what the compiler will not catch for you: ownership design that avoids gratuitous cloning, and the recurring failure modes of machine-generated Rust. 1. fuse-ai-pilot:research-expert — confirm the current stable version and any feature's stabilization release before relying on it (versions move fast). 2. fuse-ai-pilot:explore-codebase — read the crate's edition in Cargo.toml and its existing ownership conv
