Spec-Driven Development (SDD) 工作流——在改动代码前先生成一份中文设计文档(spec) 并与用户确认。**必须触发**的场景：用户提出新增功能/加一个按钮/页面/接口/字段/能力、refactor/重构、修复非平凡 bug、优化、做一个 X、涉及 2 个及以上文件的多步改动、提到「设计/方案/规划/先想清楚」。即使没说「写 spec」，只要改动不是纯 typo、文档润色、依赖升级、版本号、单行修复，都应触发。关键词(中)：新功能、新增、加、实现、重构、修复、优化、改造、调整；关键词(英)：feature、refactor、fix、optimize、redesign、rework、add、implement。

Inject lightweight AI memory system into any project. Creates memory/ directory with structured templates, appends memory usage rules to CLAUDE.md, configures PostToolUse hook for auto-syncing index timestamps, and performs atomic git commit. Trigger on: /inject-memory, 'inject memory', 'init memory', 'set up AI memory', '给这个项目加记忆系统', '注入记忆系统'.

Engineering methodology skill for all tasks. Core behaviors: clarify before assuming, investigate before asking, verify before delivering, review full dependency chains, match existing code style. Trigger on: any task start, code development, debugging, multi-step work. Do NOT skip just because the task looks easy.
