principle-subtract-before-you-add

该 Skill 提供一条软件演进原则:演进系统时先删除再构建,默认做减法。具体包括把移除排在构造之前、先精简再打磨、按实际使用而非推测性边界设计、不写超出规范所需的校验/解析/守卫、简化提示词、删除无新内容的引用而非留桩。

Subtract Before You Add

When evolving a system, remove complexity first, then build. Default to subtraction.

Make simplification a continual investment. Leave the design slightly simpler and more capable behind the same or smaller surface than you found it.

  • Sequence removal before construction
  • Cut before you polish (get to the minimum before investing in quality)
  • Design for observed usage, not speculative edge cases
  • No speculative validators, parsers, or guards beyond what the spec demands
  • Simplify prompts (remove redundant instructions, excessive templates)
  • When a reference has no novel content, delete it rather than leaving a stub
