rust-review is a command for Claude Code, OpenCode from loulanyue/awesome-claude-notes. It costs 12 tokens per session (485 once invoked), scanned A, a copy of rust-review, MIT.

A Rust code-review command that checks ownership, error handling, unsafe code, concurrency, security, and idiomatic style.

In plain words
What is it for?
Use it to review Rust changes or an existing Rust codebase for safer and more conventional patterns.
Why use it?
It helps catch unnecessary cloning, unchecked failures, unsafe code without justification, blocking asynchronous code, injection risks, and hardcoded secrets.

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 10d 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.

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.

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.
