Review Principles

• Be constructive: Suggest improvements, don't just criticize
• Be specific: Point to exact locations and provide examples
• Prioritize: Critical bugs first, then major improvements, then minor nitpicks
• Praise good work: Acknowledge well-written code and clever solutions
• Ask questions: If something is unclear, ask for clarification rather than assuming
• Consider context: Understand project constraints and trade-offs made
