What Nexus Query does

Nexus Query answers code-structure questions from AST data, such as who imports a module, what depends on an interface, and how far a change will ripple. Use it before refactors, interface changes, or when estimating risk in large legacy codebases.

Nexus Query is cataloged under AI Engineering on DirSkills. Nexus Query comes from a repository tagged agent-skills, agentic-ai, ai-coding, ai-tools and ast.

Documentation

README

Excerpt

nexus-query — 代码结构精准查询

何时调用

场景	调用
「这个文件有哪些类/方法，依赖什么」	是
「改这个接口/模块，哪些文件受影响」	是
「这个改动的影响半径是多大」	是
「项目里谁是真正的核心依赖节点」	是
「整个项目大概分哪几块」	是
用户希望生成完整的 `.nexus-map/` 知识库	否 → 改用 nexus-mapper
运行环境无 shell 执行能力	否
宿主机无本地 Python 3.10+	否

前提：确保 ast_nodes.json 可用

进入查询前 → 检查是否有 ast_nodes.json
├── 有（.nexus-map/raw/ast_nodes.json 或用户指定路径）→ 直接查询
└── 没有 → 运行 extract_ast.py 生成 → 再查询

生成 AST 时，支持与 nexus-mapper 一致的扫描过滤：

--exclude-dirs django_static,.go_root 按目录名或仓库相对路径忽略杂物目录
--use-gitignore 启用 <repo_path>/.gitignore 规则（默认开启），忽略其中声明的文件和目录
--no-gitignore 不应用 .gitignore 规则；此时仍会保留内置排除项和 --exclude-dirs

This is the opening of the README. Read the full README on GitHub.
