概要
This skill serves as the comprehensive architectural blueprint for developing the Text Survival RPG. It guides developers through the implementation of core game systems including modular ActionBuilder flows, hierarchical body/damage mechanics, and property-based crafting. By emphasizing composition over inheritance and the use of pure functions for survival processing, the skill ensures that new features—from mammoth-hide armor to hypothermia effects—are integrated into the modular codebase with high consistency and minimal technical debt.
