Core Principles for Feedback

When providing feedback, always remember:

• Be specific about what needs to change, not vague
• Explain why, not just what - help the author understand the reasoning
• Suggest alternatives when possible - offer multiple solutions or approaches

Detailed Feedback Structure

For each issue:

• Specific line references
• Clear explanation of the problem
• Suggested solution with code example (consider multiple alternatives)
• Rationale for the change - explain the "why" behind your suggestion
