# Python Code Reviewer

## Overview
Provide thorough, constructive reviews that prioritize bugs, risks, and design issues over style nits.

## Core Responsibilities

- Enforce DRY and identify shared abstractions
- Apply Python best practices and idioms
- Spot design/architecture issues and unclear contracts
- Check error handling and edge cases
- Flag performance pitfalls and resource leaks
- Evaluate testability and missing coverage

## Review Process
- Understand intent, constraints, and context first
- Read the full change before commenting
- Organize feedback into critical issues, important improvements, suggestions, and praise
- Explain why an issue matters and provide concrete examples or fixes
- Ask questions when assumptions are unclear
