Rust Coding Guidelines (50 Core Rules)

Naming (Rust-Specific)

Rule	Guideline
No `get_` prefix	`fn name()` not `fn get_name()`
Iterator convention	`iter()` / `iter_mut()` / `into_iter()`
Conversion naming	`as_` (cheap &), `to_` (expensive), `into_` (ownership)
Static var prefix	`G_CONFIG` for `static`, no prefix for `const`

Data Types

Rule	Guideline
Use newtypes	`struct Email(String)` for domain semantics
Prefer slice patterns	`if let [first, .., last] = slice`
Pre-allocate	`Vec::with_capacity()`, `String::with_capacity()`
Avoid Vec abuse	Use arrays for fixed sizes

Strings

Rule	Guideline
Prefer bytes	`s.bytes()` over `s.chars()` when ASCII
Use `Cow<str>`	When might modify borrowed data
Use `format!`	Over string concatenation with `+`
Avoid nested iteration	`contains()` on string is O(n*m)

Error Handling

Rule	Guideline
Use `?` propagation	Not `try!()` macro
`expect()` over `unwrap()`	When value guaranteed
Assertions for invariants	`assert!` at function entry

Memory

Rule	Guideline
Meaningful lifetimes	`'src`, `'ctx` not just `'a`
`try_borrow()` for RefCell	Avoid panic
Shadowing for transformation	`let x = x.parse()?`

Concurrency

Rule	Guideline
Identify lock ordering	Prevent deadlocks
Atomics for primitives	Not Mutex for bool/usize
Choose memory order carefully	Relaxed/Acquire/Release/SeqCst

Async

Rule	Guideline
Sync for CPU-bound	Async is for I/O
Don't hold locks across await	Use scoped guards

Macros

Rule	Guideline
Avoid unless necessary	Prefer functions/generics
Follow Rust syntax	Macro input should look like Rust

Deprecated → Better

Deprecated	Better	Since
`lazy_static!`	`std::sync::OnceLock`	1.70
`once_cell::Lazy`	`std::sync::LazyLock`	1.80
`std::sync::mpsc`	`crossbeam::channel`	-
`std::sync::Mutex`	`parking_lot::Mutex`	-
`failure`/`error-chain`	`thiserror`/`anyhow`	-
`try!()`	`?` operator	2018

Quick Reference

Naming: snake_case (fn/var), CamelCase (type), SCREAMING_CASE (const)
Format: rustfmt (just use it)
Docs: /// for public items, //! for module docs
Lint: #![warn(clippy::all)]

★★★★★Emma Thompson· Dec 24, 2024
coding-guidelines is among the better-maintained entries we tried; worth keeping pinned for repeat workflows.
★★★★★Kofi Bhatia· Dec 8, 2024
Solid pick for teams standardizing on skills: coding-guidelines is focused, and the summary matches what you get after install.
★★★★★Yash Thakker· Nov 27, 2024
Registry listing for coding-guidelines matched our evaluation — installs cleanly and behaves as described in the markdown.
★★★★★Amina Ghosh· Nov 27, 2024
We added coding-guidelines from the explainx registry; install was straightforward and the SKILL.md answered most questions upfront.
★★★★★Emma Park· Nov 15, 2024
Useful defaults in coding-guidelines — fewer surprises than typical one-off scripts, and it plays nicely with `npx skills` flows.
★★★★★Dhruvi Jain· Oct 18, 2024
coding-guidelines reduced setup friction for our internal harness; good balance of opinion and flexibility.
★★★★★Amina Mehta· Oct 18, 2024
coding-guidelines fits our agent workflows well — practical, well scoped, and easy to wire into existing repos.
★★★★★Amina Robinson· Oct 6, 2024
I recommend coding-guidelines for anyone iterating fast on agent tooling; clear intent and a small, reviewable surface area.
