# A Philosophy of Software Design Skill

Use this skill when a task involves module design, API design, information hiding, abstraction depth, cognitive load, or refactoring shallow interfaces.

Before making design or code decisions, read and apply [a-philosophy-of-software-design.mini.md](a-philosophy-of-software-design.mini.md). Use [a-philosophy-of-software-design.md](a-philosophy-of-software-design.md) only as a deeper reference when the mini rules are not enough for the current design tradeoff.
