Librarian Skill
Librarian Skill
Use this skill when you need deep understanding of external codebases.
Best-use cases:
Explain how a third-party library works internally.
Find real implementation patterns in public code.
Compare two libraries/frameworks for a specific capability.
Trace architecture and execution flow across a repository.
Tool routing:
Official docs/API questions: use documentation lookup first.
Real-world code usage patterns: search public repositories.
Internal implementation details: fetch source and read targeted files.
Execution pattern:
Identify target library/repo and scope the question.
Collect high-signal files (README, package metadata, entry points).
Inspect implementation files for the asked behavior.
Synthesize findings with concrete file evidence.
Output style:
Give direct answer first.
Support with precise file references.
Use a diagram if system flow is non-trivial.
当你需要深入理解外部代码库时，可以使用这个Skill。
最佳使用场景：
解释第三方库的内部工作机制
在公开代码中查找真实的实现模式
针对特定功能对比两个库/框架
追踪仓库中的架构和执行流程
工具路由策略：
官方文档/API相关问题：优先使用文档查询工具
真实代码使用模式：搜索公开代码仓库
内部实现细节：获取源码并读取目标文件
执行流程：
确定目标库/仓库并明确问题范围
收集高价值文件（README、包元数据、入口文件）
检查实现文件以找到对应功能的实现
结合具体文件证据总结研究结果
输出风格：
先给出直接答案
提供精确的文件引用作为支撑
