Can I use this for existing projects?

Yes, it includes tools for analyzing current system designs, identifying technical debt, and retroactively documenting existing architectural decisions.

What is an ADR in this skill?

An Architecture Decision Record (ADR) is a short document that captures a significant design choice, including its context, the rationale behind the decision, and its long-term consequences.

How does this skill help with pattern selection?

It provides decision trees and a reference guide to help you choose the right architectural patterns, such as MVC, Hexagonal, or Event-Driven, based on your specific requirements.

Why does the skill emphasize simplicity?

It follows the principle that simplicity is the ultimate sophistication, encouraging developers to add complexity only when necessary to ensure the system remains maintainable.

Productivity & Workflow

Guides architectural decision-making through requirements analysis, trade-off evaluation, and ADR documentation.

This skill provides a structured framework for making and documenting high-level system design decisions within Claude Code. It helps developers move beyond trial-and-error by implementing a systematic approach to pattern selection, constraint identification, and the creation of Architecture Decision Records (ADRs). By emphasizing simplicity and evidence-based trade-offs, it ensures that technical choices are well-reasoned, scalable, and clearly communicated to the rest of the team.
