Rust Review Workflow

Expert-level Rust code audits with focus on safety, correctness, and idiomatic patterns.

Quick Start

/rust-review

Verification: Run the command with --help flag to verify availability.

When To Use

• Reviewing Rust code changes
• Auditing unsafe blocks
• Analyzing concurrency patterns
• Dependency security review
• Performance optimization review

When NOT To Use

• General code review without Rust - use unified-review
• Performance profiling - use parseltongue:python-performance pattern

Required TodoWrite Items

1. rust-review:ownership-analysis
2. rust-review:error-handling
3. rust-review:concurrency
4. rust-review:unsafe-audit
5. rust-review:cargo-deps
6. rust-review:evidence-log

Progressive Loading

Load modules as needed based on review scope:

Quick Review (ownership + errors):

• See modules/ownership-analysis.md for borrowing and lifetime analysis
• See modules/error-handling.md for Result/Option patterns

Concurrency Focus:

• See modules/concurrency-patterns.md for async and sync primitives

Safety Audit:

• See modules/unsafe-audit.md for unsafe block documentation

Dependency Review:

• See modules/cargo-dependencies.md for vulnerability scanning

Idiomatic Patterns:

• See modules/builtin-preference.md for conversion traits and builtin preference

Core Workflow

1. Ownership Analysis: Check borrowing, lifetimes, clone patterns
2. Error Handling: Verify Result/Option usage, propagation
3. Concurrency: Review async patterns, sync primitives
4. Unsafe Audit: Document invariants, FFI contracts
5. Dependencies: Scan for vulnerabilities, updates
6. Evidence Log: Record commands and findings

Rust Quality Checklist

Safety

• [ ] All unsafe blocks documented with SAFETY comments
• [ ] FFI boundaries properly wrapped
• [ ] Memory safety invariants maintained

Correctness

• [ ] Error handling complete
• [ ] Concurrency patterns sound
• [ ] Tests cover critical paths

Performance

• [ ] No unnecessary allocations
• [ ] Borrowing preferred over cloning
• [ ] Async properly non-blocking

Idioms

• [ ] Standard traits implemented
• [ ] Conversion traits preferred over helper functions
• [ ] Error types well-designed
• [ ] Documentation complete

Output Format

## Summary
Rust audit findings

## Ownership Analysis
[borrowing and lifetime issues]

## Error Handling
[error patterns and issues]

## Concurrency
[async and sync patterns]

## Unsafe Audit
### [U1] file:line
- Invariants: [documented]
- Risk: [assessment]
- Recommendation: [action]

## Dependencies
[cargo audit results]

## Recommendation
Approve / Approve with actions / Block

Verification: Run the command with --help flag to verify availability.

Exit Criteria

Troubleshooting

Common Issues

Command not found Ensure all dependencies are installed and in PATH

Permission errors Check file permissions and run with appropriate privileges

Unexpected behavior Enable verbose logging with --verbose flag
