rust-review

A Rust code-review command that checks code for common safety, ownership, error-handling, and concurrency problems. Rust is a programming language that strictly manages memory and shared data.

In plain words
What is it for?
Use it to review Rust code, including borrowing and lifetimes, unsafe blocks, error propagation, secrets, database or command injection, channels, locks, and Send/Sync usage.
Why use it?
It helps catch unsafe patterns, needless copying, hidden errors, injection risks, and blocking work in asynchronous code before they reach production.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

rust-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to rust-review — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Rust Review Command

Review Rust code for idiomatic patterns and best practices: $ARGUMENTS

Your Task

  1. Analyze Rust code for idioms and patterns
  2. Check ownership - borrowing, lifetimes, unnecessary clones
  3. Review error handling - proper ? propagation, no unwrap in production
  4. Verify safety - unsafe usage, injection, secrets

Review Checklist

Safety (CRITICAL)

  • No unchecked unwrap()/expect() in production paths
  • unsafe blocks have // SAFETY: comments
  • No SQL/command injection
  • No hardcoded secrets

Ownership (HIGH)

  • No unnecessary .clone() to satisfy borrow checker
  • &str preferred over String in function parameters
  • &[T] preferred over Vec<T> in function parameters
  • No excessive lifetime annotations where elision works

Error Handling (HIGH)

  • Errors propagated with ?; use .context() in anyhow/eyre application code
  • No silenced errors (let _ = result;)
  • thiserror for library errors, anyhow for applications

Concurrency (HIGH)

  • No blocking in async context
  • Bounded channels preferred
  • Mutex poisoning handled
  • Send/Sync bounds correct

Code Quality (MEDIUM)

  • Functions under 50 lines
  • No deep nesting (>4 levels)
  • Exhaustive matching on business enums
  • Clippy warnings addressed

Report Format

CRITICAL Issues

  • [file:line] Issue description Suggestion: How to fix

HIGH Issues

  • [file:line] Issue description Suggestion: How to fix

MEDIUM Issues

  • [file:line] Issue description Suggestion: How to fix

TIP: Run cargo clippy -- -D warnings and cargo fmt --check for automated checks.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
