Rust Best Practices

A condensed rulebook from five major Rust guides that makes Claude write, review, and refactor idiomatic, robust Rust.

What it does

  • Triggers automatically on any mention of Rust, cargo, crates, .rs files, the borrow checker, lifetimes, traits, clippy, or rustfmt — even without the words "best practices".
  • Synthesizes the Google Rust Style Guide, Rust API Guidelines, Effective Rust, Rust Design Patterns, and Microsoft's Pragmatic Rust Guidelines, and states which source wins when they disagree.
  • Covers 13 areas: ownership and borrowing tactics, naming tables, newtypes and builders, error-type design and panic policy, async/concurrency, unsafe and FFI, crate/feature/semver hygiene, docs, tests, and performance.
  • Enforces a pre-delivery loop of cargo fmt, cargo clippy --all-targets --all-features -- -D warnings, cargo test, cargo doc, plus a final self-review checklist.

Who it's for

  • Developers learning Rust or carrying C++/Java/Python habits into it.
  • Library authors who must get public API shape, error types, and semver right.
  • Teams wanting a consistent, citable Rust review standard.

Example uses

  1. "Refactor this module" — strips clones that only silence the borrow checker, &String/&Vec<T> params, get_ getters, and bool flags, while preserving public behavior.
  2. "Design the error type for this crate" — produces a thiserror enum implementing Error + Display + Send + Sync + 'static with source() and From conversions.
  3. "Review this unsafe block" — checks for // SAFETY: comments, # Safety docs, minimal unsafe scope, and suggests Miri runs.

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/morganlinton/BeautifulRust/HEAD/skills/rust-best-practices/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the skills/rust-best-practices folder from the GitHub repo morganlinton/BeautifulRust into my ~/.claude/skills/rust-best-practices/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/morganlinton/BeautifulRust.git /tmp/BeautifulRust && mkdir -p ~/.claude/skills && cp -r /tmp/BeautifulRust/skills/rust-best-practices ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/morganlinton/BeautifulRust.git
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r BeautifulRust/skills/rust-best-practices ~/.claude/skills/
  5. Confirm the references/ folder came along — it holds the digests the skill cites.
  6. Restart Claude Code and run /skills to verify it is listed.
  7. Open a Rust project and ask something like "make this function idiomatic". Make sure cargo, clippy, and rustfmt are installed so the verification commands can run.
