# Sentry Code Review

Follow these guidelines when reviewing code for Sentry projects.

## Review Checklist

### Identifying Problems

Look for these issues in code changes:

- **Runtime errors**: Potential exceptions, null pointer issues, out-of-bounds access
- **Performance**: Unbounded O(n²) operations, N+1 queries, unnecessary allocations
- **Side effects**: Unintended behavioral changes affecting other components
- **Backwards compatibility**: Breaking API changes without migration path
