Rust Skills

265 Rust rules your AI coding agent can use to write better code. Current for Rust 1.96 (2024 edition).

Works with Claude Code, Cursor, Windsurf, Copilot, Codex, Aider, Zed, Amp, Cline, and pretty much any other agent that supports skills.

Why

Out of the box, coding agents write average Rust — they clone to dodge the borrow checker, .unwrap() everything, and reach for Box<dyn Trait> when impl Trait would do. These rules encode what expert Rust actually looks like: idiomatic, fast, and safe. Each rule is small and focused, so the agent pulls in only what's relevant to the code in front of it.

Install

npx add-skill leonardomso/rust-skills

That's it. The CLI figures out which agents you have and installs the skill to the right place.

How to use it

After installing, just ask your agent:

/rust-skills review this function

/rust-skills is my error handling idiomatic?

/rust-skills check for memory issues

/rust-skills is this unsafe block sound?

The agent loads the relevant rules and applies them to your code.

See it in action

Ask the agent to review a function like this:

// before
fn first_word(s: &String) -> String {
    s.clone().split_whitespace().next().unwrap().to_string()
}

With these rules loaded, it knows to take &str instead of &String, drop the needless clone() and allocation, and return an Option instead of panicking:

// after — applies own-slice-over-vec, own-borrow-over-clone, anti-unwrap-abuse
fn first_word(s: &str) -> Option<&str> {
    s.split_whitespace().next()
}
