Software Architecture skill: what it does and how to install it

What it does. Applies Clean Architecture and domain-driven design to software development, separating business logic from frameworks, interfaces and infrastructure. It favours existing libraries, early returns, focused functions, domain-specific names and clear boundaries between responsibilities.

When to use it. For writing code, designing architecture or analysing software structure. It does not replace environment-specific validation, testing or expert review, and asks for clarification when requirements or success criteria are missing.
