A checklist for reviewing Rust code, a programming language with strict rules for memory and data sharing. It examines ownership, error handling, unsafe code, security, and asynchronous code.

Use it to review Rust functions, modules, or changes for borrowing and lifetime issues, unnecessary copies, weak error handling, unsafe blocks, injection risks, secrets, and concurrency problems.

It helps spot code that may be unsafe, unnecessarily complicated, or likely to fail at runtime. It also checks whether the code follows common Rust practices.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00012	$0.00485
Opus 5	$0.00006	$0.00243
Sonnet 5	$0.00002	$0.00097
Haiku 4.5	$0.00001	$0.00049

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 6d 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

What it actually says

Rust Review Command

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

Your Task

Analyze Rust code for idioms and patterns
Check ownership - borrowing, lifetimes, unnecessary clones
Review error handling - proper ? propagation, no unwrap in production
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

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.

rust-review is a command published in the GitHub repository SiniyaYousuf/everything_claudecode (14 stars, last pushed 5mo ago), licensed MIT. It adds 12 tokens to every session and 485 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to rust-review, differing in 0 lines, and is treated as a copy.
