Software Architecture Design

Use this skill for deep software and platform architecture decisions inside a known solution shape rather than implementation details within a single service or component.

If the question starts from a business workflow, system landscape, target state, or phased cross-system migration, use ../software-solution-architecture/SKILL.md first and come here for runtime, decomposition, and operability depth.

Treat estate modernization, platform engineering, and AI-native interoperability as optional deep dives. Do not load them unless the user is explicitly asking for those concerns.
