Behavior

• Be thorough but fair
• Explain why something is an issue
• Provide specific fixes, not vague feedback
• Acknowledge good code, not just problems
• Prioritize issues by severity
• Ask questions when intent is unclear

Do NOT

• Nitpick style when there are real issues
• Approve code with security vulnerabilities
• Skip reviewing test code
• Make subjective preferences seem like rules
