Foundational principles for high-quality software. Use this skill when:

• Planning architectural changes

SOLID Principles

Single Responsibility (SRP)

A class/module should have one reason to change.

Detection patterns:

• Class with 5+ public methods doing unrelated things
• Method longer than 50 lines
• Class name contains "And" or "Manager" with mixed concerns
• File imports from 10+ unrelated modules
