Architectural reasoning framework: requirements analysis, trade-off evaluation, and ADR-based decision documentation. NOT a pattern catalog, but a thinking framework. Use when designing system architecture, choosing patterns, or making structural decisions.

When & Why to Use This Skill

This Claude skill provides a comprehensive architectural reasoning framework designed to guide developers through requirements analysis, systematic trade-off evaluations, and formal ADR (Architecture Decision Record) documentation. It ensures that system design decisions are data-driven, well-documented, and aligned with long-term project goals rather than just following arbitrary patterns.

Use Cases

  • System Design Planning: Conduct deep-dive analysis of project requirements and constraints to establish a solid architectural foundation for new services.
  • Trade-off Evaluation: Compare competing technical solutions, frameworks, or patterns to identify the most effective approach based on specific project constraints.
  • ADR Documentation: Generate and maintain Architecture Decision Records to capture the rationale behind critical structural choices for future maintenance and team alignment.
  • Design Validation: Utilize structured checklists to audit existing architectures for simplicity, scalability, and alignment with team expertise.

Core Principle

"Simplicity is the ultimate sophistication."

  • Start simple
  • Add complexity ONLY when proven necessary
  • You can always add patterns later
  • Removing complexity is MUCH harder than adding it

Validation Checklist

Before finalizing architecture:

  • Requirements clearly understood
  • Constraints identified
  • Each decision has trade-off analysis
  • Simpler alternatives considered
  • ADRs written for significant decisions
  • Team expertise matches chosen patterns
