How does this help with refactoring?

By mapping variable scopes and method call graphs, it ensures that changes to a specific function or class are analyzed for their impact across the entire codebase.

Can this skill help find circular dependencies?

Yes, it analyzes the import structure across project files to identify and visualize circular import chains that often lead to runtime errors.

What is AST analysis compared to regular text search?

Unlike text search which looks for strings, AST analysis understands code syntax and semantics, allowing for precise tracking of variables, functions, and logic regardless of formatting.

Which languages are supported by the AST Analyzer?

The skill currently provides specialized support for Python (via the ast module) as well as JavaScript and TypeScript (via Babel/Acorn parsers).

Does it detect code smells automatically?

Yes, it is designed to identify structural issues such as 'God Classes', excessively long functions, and deep nesting levels that impact maintainability.

Developer Tools

Performs deep Abstract Syntax Tree analysis to map code structures, track dependencies, and detect architectural patterns.

About

The AST Analyzer skill empowers Claude with the ability to look past raw text and understand the underlying structural logic of your codebase. By parsing source code into Abstract Syntax Trees, it enables precise refactoring, comprehensive class hierarchy mapping, and the detection of complex code smells like God Classes or deep nesting. Whether you are performing a large-scale migration, tracking variable scopes, or auditing circular dependencies, this skill provides the semantic depth needed for reliable code intelligence across Python, JavaScript, and TypeScript.

9 GitHub stars
Comprehensive class hierarchy and method call graph extraction
Deep dependency mapping including circular import detection

Use Cases

Auditing dependency graphs to resolve circular imports and unused modules
Identifying architectural technical debt like God Classes or overly complex nested loops
Mapping legacy codebases to understand complex class inheritances and call chains
