BeautifulRust: agent skills for idiomatic Rust

Summary

BeautifulRust is an MIT-licensed set of three Agent Skills and a clippy configuration that teach coding agents to write, review, and port idiomatic Rust. It installs as a Claude Code plugin or as plain skill folders for Codex and other agents. It appeared on GitHub around 2026-10-23 and had about 1,300 stars five days later (the publish date is estimated from that).

Key points

• Skills: rust-best-practices loads when the agent writes or changes Rust; rust-review reviews a file, crate, or diff and gives a prioritised report where each finding cites its rule and shows a fix; rust-port ports C, C++, Python, Go, or JavaScript to Rust, porting the original tests first.
• Lints: a drop-in clippy config in lints/ enforces the machine-checkable rules in CI. There is also a Bevy reference.
• Install in Claude Code: /plugin marketplace add morganlinton/BeautifulRust, then /plugin install beautiful-rust@beautiful-rust.
• Install in Codex: clone the repo and copy skills/rust-* into ~/.agents/skills/ (or .agents/skills/ in a project), or run npx skills add morganlinton/BeautifulRust -a codex.
• Author's benchmark: pass rate rose from 72/85 to 80/85 with Claude Code and from 53/85 to 76/85 with Codex CLI. These were single runs graded by a Claude model, so treat them as indicative.

Why it matters

It is a good example of a narrow, testable skill pack: the review skill gives cited findings, and the clippy config backs the same rules up in CI.
