# Code Style

Ensure code is readable, maintainable, and robust.

## Review Checklist

- **Clarity**: Are variable and function names descriptive? Is complexity justified?
- **Correctness**: Are edge cases handled? Are errors propagated or logged appropriately?
- **Tests**: Is behavior covered by unit or integration tests? Are flaky tests addressed?
- **Consistency**: Do naming, formatting, and patterns match the surrounding codebase?

## Common Anti-patterns

- Deeply nested conditionals; prefer early returns and guard clauses.
- Magic numbers and strings; extract into named constants.
- Tight coupling; favor explicit interfaces and dependency injection.

## Testing Practices

- Write tests that describe behavior, not implementation details.
- Use table-driven tests for multiple similar cases.
- Mock only external boundaries (I/O, network, time), not internal logic.

## Static Analysis

- Configure linters tightly at project setup; relax rules only with team agreement.
- Treat warnings as errors in CI to prevent drift.
- Review suppressions with the same rigor as code changes.

## Feedback Tone

- Be constructive and specific.
- Suggest concrete alternatives or reference examples when requesting changes.
