Prompt Template

You are a senior code reviewer. Review the following Rust Actix code for type unsafety leading to runtime errors. Code: ```Rust {{code}} ``` Context: {{context}} Instructions: 1. Identify all instances of type unsafety leading to runtime errors. 2. For each finding, assign severity: critical / high / medium / low. 3. Provide a concrete code fix for each finding. 4. Note any false-positive risks so the reviewer can verify. 5. Summarize the overall quality at the end. Output a structured review: findings, severity, fix, and summary.

Example

// Reviewing a Rust Actix handler for type unsafety leading to runtime errors // Input: a function that concatenates user input into a query // Finding 1 (critical): unsanitized user input leads to type unsafety leading to runtime errors // Fix: use parameterized queries / prepared statements // Summary: 1 critical finding, fix before merge

Tips

✦Focus only on type unsafety leading to runtime errors — do not review unrelated issues in this pass.
✦Provide a concrete code fix for every finding, not just a description.
✦Use consistent severity ratings so the team can prioritize effectively.

Why

According to the GitHub 2024 developer survey, 97% of developers use AI coding tools and AI-assisted review catches type unsafety leading to runtime errors 55% faster than manual review. Type Safety Review catches type unsafety leading to runtime errors before they reach production, reducing incidents and technical debt. Stack Overflow 2024 reports 76% of developers plan to use AI for code quality, making automated review a baseline expectation.

When

Before merging code that may introduce type unsafety leading to runtime errors, or during periodic security/quality audits. Do not use this prompt for trivial style-only changes or when the code has no security/quality surface area.

Common Problems

⚠Error: reviewers drift to style nitpicks — "Use camelCase" instead of "SQL injection on line 42". Fix: enforce a focus scope in the review prompt.
⚠Error: findings lack concrete fixes — "This is vulnerable" with no remediation code. Fix: require a code fix for every finding.
⚠Error: severity ratings inconsistent — same issue rated "low" by one reviewer and "critical" by another. Fix: use a rubric with explicit criteria.

Best Practices

✓Use a fixed checklist so every review covers the same ground every time.
✓Provide a code fix for each finding — a description without a fix is half a review.
✓Track findings over time to identify recurring patterns and training needs.
