What it does

Rust Conventions is an agent skill from Goldziher/ai-rulez. Rust code conventions covering edition 2024, cargo fmt/clippy, Result-based error handling, unsafe discipline, async with tokio, API-guideline naming, trait implementations, benchmarking, and security scanning. Load when writing or reviewing Rust code.

Its SKILL.md is about 750 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering API design. It works with Rust. The repository describes itself as: One source of truth for AI assistant configs: 14 built-in presets (Claude, Cursor, Copilot, Codex, Gemini, Xum, …), full-parity custom presets, and distributable plugin bundles… The licence is MIT.

When your agent uses it

  • Tasks that involve API design

Example prompts

  • “/rust-conventions”

What it can do on your machine

Read from SKILL.md and the folder at commit 2dbd6a4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • cargo

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • rust-lang.github.io
    • rust-unofficial.github.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Rust Conventions loads about 746 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 317 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~746

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Rust code conventions covering edition 2024, cargo fmt/clippy, Result-based error handling, unsafe discipline, async with tokio, API-guideline naming, trait implementations, benchmarking, and security scanning. Load when writing or reviewing Rust code.
  • Rust 2024 edition, cargo fmt + clippy -D warnings, zero warnings policy.
  • Result<T, E> with a derive-based error crate (e.g., thiserror) for library errors, a context-adding error crate (e.g., anyhow) for applications. ? for propagation — never .unwrap() in library code.
  • Minimize unsafe — every block needs // SAFETY: comment explaining invariants.
  • Prefer &str over String in params, Cow<'_, str> for conditional ownership, Arc for shared ownership.
  • impl Trait in argument position for static dispatch, dyn Trait for dynamic dispatch when heterogeneous collections needed.
  • Small, focused modules. Use pub(crate) for internal visibility. Workspace inheritance for multi-crate repos.
  • #[cfg(test)] for unit tests, tests/ for integration, a coverage tool (e.g., cargo-llvm-cov) for coverage.
  • Benchmarking: a statistical benchmark harness (e.g., criterion) for microbenchmarks, profile with a flamegraph tool (e.g., cargo flamegraph).
  • Async: tokio runtime, 'static + Send + Sync bounds, tokio::spawn for concurrency.
  • Security: cargo audit for CVE scanning, cargo deny for license and advisory policies.
  • Dependencies: pin versions, commit Cargo.lock, prefer well-maintained crates.
  • Structured logging (spans and events, e.g., the tracing crate) — not println!.
  • API naming: follow as_/to_/into_ conventions for conversions, iter()/iter_mut()/into_iter() for iterators. Getters are field() not get_field(). See Rust API Guidelines.
  • Eagerly implement common traits: Clone, Debug, Default, Eq, PartialEq, Hash, Send, Sync. Use From/AsRef/AsMut for conversions, FromIterator/Extend for collections.
  • Type safety: newtypes for static distinctions, builder pattern for complex construction, bitflags over enums for flag sets. Avoid bool params — use custom types or enums.
  • Constructors: new() as static inherent methods. No out-parameters. Only smart pointers implement Deref/DerefMut.
  • API flexibility: minimize parameter assumptions via generics, make traits object-safe when trait objects may be useful. Let callers decide where to copy and place data.
  • Rustdoc: all public items have doc examples using ? (not unwrap). Document errors, panics, and safety invariants. Hyperlink related items.
  • Future-proofing: seal traits to prevent downstream implementations, keep struct fields private, don't duplicate derived trait bounds on structs. See Rust Design Patterns.
  • Anti-patterns: unwrap(), unguarded unsafe, panics in libraries, Vec/HashMap across FFI.

Can I use Rust Conventions in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Goldziher/ai-rulez --skill rust-conventions -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rust-conventions, .gemini/skills/rust-conventions, .github/skills/rust-conventions and .opencode/skills/rust-conventions in your project.

What does Rust Conventions need to run?

Going by SKILL.md and its folder, Rust Conventions needs the command-line tools its instructions call (cargo).

Does Rust Conventions access the network?

SKILL.md names 2 domains. As links in the text: rust-lang.github.io and rust-unofficial.github.io. This is read from the text; nothing was executed.

Is Rust Conventions safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Rust Conventions use?

Rust Conventions is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Rust Conventions use?

About 746 tokens (SKILL.md is roughly 3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
