Coding & Dev Tools Agent Skills
Coding agent skills teach AI agents repeatable engineering workflows: reviewing pull requests, writing tests, refactoring safely, and enforcing house style. Install one SKILL.md and your agent applies the same checklist every time, whether you use Claude Code, Cursor, Codex, or another agent.

rollrollroll Codebase Analyzer
对一个软件项目或源码仓库进行全面调研，输出一份结构化的中文调研报告，让对项目不熟悉的人能够同时理解"它做什么"和"它怎么实现"。当用户说"调研这个项目 / 分析这个代码库 / 给我一份项目分析报告 / 我要全面理解这个项目 / 帮我看看这个仓库 / onboarding 一下 / 这个项目的整体架构是什么 / 给我梳理下这个源码"等等，或者把一个不熟悉的代码目录交给你并希望你给出全局认识时，必须使用本 skill。即使用户没有显式说"调研报告"，只要意图是"帮我搞懂一个完整的代码库 / 项目"，就应当触发。但本 skill 仅针对"全局理解 / 架构调研 / onboarding"场景：若用户只是要做 code review、定位某个 bug、评审某处具体实现、做性能或安全诊断，不要触发本 skill。
