Code Quality & Architecture Sub-Skill

Architecture patterns, code quality, refactoring, and development practices.

Purpose

Handles architecture patterns, code decomposition, refactoring, code review, development practices, and tech debt management.

Context Discovery

Auto-Investigation

Signal	Check For	Why
Architecture docs	ADRs, C4 diagrams, domain models	Architecture patterns in use
Code review comments	Review patterns, quality standards	Review culture
Linting config	ESLint, Prettier, ruff rules	Code quality standards
Tech debt tracking	Issue labels, debt backlog	Tech debt awareness
Documentation quality	CLAUDE.md, README patterns	Documentation standards

Discovery Questions

questions:
  - question: "What's your code quality need?"
    options:
      - label: "Architecture design"
        description: "Use clean-architecture, domain-driven-design, cqrs-pattern"
      - label: "Code review"
        description: "Use code-review, code-review-process"
      - label: "Refactoring"
        description: "Use refactoring-patterns, code-decomposition-patterns"
      - label: "Tech debt management"

  - question: "Are you working with LLMs for code generation?"
    options:
      - label: "Yes, AI-assisted development"
        description: "Apply llm-friendly-architecture"
      - label: "No, traditional development"
        description: "Standard architecture patterns"

When to Use

Architecture patterns (DDD, CQRS, Clean Architecture, Event Sourcing)
Code review and quality standards
Refactoring patterns
Code decomposition strategies
Development practices (XP, pair/mob programming)
Tech debt management
Documentation standards
LLM-friendly architecture
