architecture-introspector

USE WHEN: analyzing existing architectures, evaluating architectural decisions, identifying technical debt, planning refactoring, assessing whether patterns are justified, onboarding to complex codebases, reviewing PRs with architectural changes. DO NOT USE WHEN: simple code questions, bug fixes, feature implementation, or tasks not requiring architectural analysis. For complex architectural analysis, trigger deep thinking with "think harder" or "ultrathink" to enable thorough first-principles reasoning.
