rust-api-guidelines-skill

Enforces the official Rust API Guidelines (https://rust-lang.github.io/api-guidelines/) when writing, reviewing, or refactoring Rust library code. Use this skill whenever you are writing new Rust structs, enums, traits, functions, or modules that form a public API — including when designing error types, implementing conversions, naming methods, adding documentation, creating macros, or structuring crate features. Also use it when reviewing existing Rust code for API quality, idiomatic patterns, or crate publishing readiness. Trigger on any Rust library design task, even if the user doesn't explicitly mention "API guidelines."
