BeautifulRust

BeautifulRust teaches your coding agent to write Rust like a careful Rust developer instead of someone wrestling the borrow checker. Three Agent Skills (write, review, and port from C, C++, Python, Go or JavaScript) plus a drop-in clippy config, distilled from five sources including the Rust API Guidelines and Effective Rust. MIT and free, for Claude Code, Codex, Copilot, Cursor and Gemini CLI.

Install is one command: npx skills add morganlinton/BeautifulRust. The lint config is the part I'd take even without an agent. It flags unwrap outside tests, unsafe without a SAFETY comment, bool parameters and lossy casts, and the repo ships a crate proving every lint fires.

Solo and small teams: free, install it today. Larger teams: put the clippy config in CI. In the author's benchmark Codex went from 53 to 76 of 85 checks with the skills, Claude Code from 72 to 80.

The catch: that benchmark is one run per configuration, graded by a Claude model, and the author says so. The skills made Claude worse on the Bevy task. And the lints are strict: drop them into an existing crate with -D warnings and your build lights up before it helps.
