description	Consider code quality metrics (complexity, maintainability, LOC) injected in context when making changes. Lower maintainability (<50) or high complexity (>15) warrant refactoring.

Code Quality Metrics in Context

When you see a "Code Quality Metrics" section in your context, use it to guide refactoring decisions:

• Maintainability Index < 50: File is difficult to maintain. Consider breaking into smaller functions.
• Cyclomatic Complexity > 15: Too many branches. Simplify with early returns, extract methods, or split responsibilities.
• Lines of Code > 500: Long files should be modularized. Extract cohesive groups into separate modules.

When to Refactor

• If user asks to modify a file with low maintainability, suggest refactoring first
• If complexity is high and the change adds more branches, simplify first
• If LOC is very high (>1000), split into smaller files before making large changes

When NOT to Refactor

• User explicitly says "don't refactor, just fix the bug"
• File is a thin wrapper or data class (high LOC but low complexity = acceptable)
• Metrics are improving with current change (don't over-optimize)
