How do I extract function and class definitions from source code?▼
Parse source code into an AST using tree-sitter to extract symbol definitions. Tree-sitter queries locate functions, classes, and other structural elements across Python, JavaScript, TypeScript, Go, Rust, C, C++, Swift, Java, Kotlin, Julia, and other languages, enabling automated symbol extraction for analysis and documentation.
Can I analyze code structure and dependencies across multiple programming languages?▼
Yes. Tree-sitter provides language-agnostic AST parsing and querying across 12+ languages including Python, JavaScript, Go, and Rust. Register your project, then run tree-sitter queries to analyze code structure, identify patterns, and extract dependencies consistently regardless of the language.
What's the best way to query code patterns and locate specific syntax nodes?▼
Tree-sitter queries enable pattern-matching against AST nodes. Write queries to locate function calls, variable assignments, imports, or custom syntax patterns. Query results pinpoint exact locations, types, and relationships, making it faster than regex or manual parsing to identify code structures.
Do I need special setup or dependencies to use AST-based code analysis?▼
You need Python 3.10+, a tree-sitter-based parser, and MCP server integration. The Skill handles project registration, file exploration, and AST retrieval through exposed tools, so no manual parser configuration is required once the environment is configured.
How can I assess code complexity and understand large codebases quickly?▼
Extract AST nodes and run structural queries to measure complexity metrics, identify deeply nested code, count function definitions, and trace dependencies. Tree-sitter's structural analysis reveals patterns and hotspots faster than line-by-line review, scaling to large projects.
What languages and file types does tree-sitter support for code analysis?▼
Tree-sitter supports Python, JavaScript, TypeScript, Go, Rust, C, C++, Swift, Java, Kotlin, Julia, and more. Each language parser enables identical AST extraction and querying workflows, so you can analyze multi-language projects with consistent tools and methods.
