Code Analysis — AST, Dependency Graphs & Knowledge Graphs

Parse, analyze, and visualize code structure through AST analysis, dependency graphing, and knowledge extraction. Supports Python (via ast module) and JavaScript/TypeScript (via grep-based import parsing and optional @babel/parser / ts-morph).

When to use

Use this skill when:

• Building or updating a dependency graph of the codebase
• Analyzing imports to detect circular dependencies or layer violations
• Parsing Python AST to extract class hierarchies, function signatures, or call graphs
• Parsing JavaScript/TypeScript source to extract React component trees, ESM imports, and hook usage
• Generating a knowledge graph of code entities and their relationships
• Measuring code complexity (cyclomatic, cognitive, LOC) per module
• Identifying dead code, unused imports, or orphan modules
• Mapping how data flows through the SDK layers or SPA component hierarchy
• Understanding coupling between modules before a refactor
• Analyzing a SPA's source code structure (component graph, barrel exports, route tree)
