Systematically understands and documents legacy codebases that have no documentation, original developers are gone, and no one knows how it works. Use this skill when inheriting unknown code, onboarding to legacy systems, preparing legacy migration, or trying to make changes without breaking undocumented behavior. Triggers on: 'understand old code', 'no documentation', 'original developer left', 'legacy system', 'inherited codebase', 'how does this work', 'afraid to change this', 'spaghetti code', 'COBOL', 'PHP legacy', '20 year old code', 'no tests', 'black box system', 'reverse engineer this'. US technical debt: $1.52 trillion. 80% of federal IT budgets spent on maintaining legacy systems. This skill makes the unknown known.

系统性地理解并记录没有文档、原开发者已离开且无人知晓其工作原理的遗留代码库。在继承未知代码、加入遗留系统、准备遗留迁移或在不破坏未记录行为的情况下尝试修改时使用此技能。触发词示例：'理解旧代码'，'无文档'，'原开发者离职'，'遗留系统'，'继承的代码库'，'这是如何工作的'，'害怕修改'，'意大利面代码（spaghetti code）'，'COBOL'，'PHP 遗留'，'20 年前的代码'，'无测试'，'黑箱系统'，'逆向工程'. 美国技术债务：1.52万亿美元。联邦 IT 预算的 80% 用于维护遗留系统。该技能将未知变为已知。
