Provides a high-level summary of all symbols (classes, interfaces, types, enums, functions) in a TypeScript/JavaScript file

Analyzes all TypeScript/JavaScript files in a directory, providing a package-level summary

Lists all functions and methods in a TypeScript/JavaScript file with their signatures and line ranges

Extracts the full body of a specific function or method. Supports Class.method syntax.

Lists all methods for a specific class in a TypeScript/JavaScript file

Extracts the full definition of any type (interface, type alias, class, enum) by name

Lists package-level constant and variable declarations in a TypeScript/JavaScript file

Lists all exported symbols with their kind (function, class, interface, type, variable, re-export)

Lists all import statements in a TypeScript/JavaScript file with their bindings and module paths

Finds all occurrences of a specific identifier (variable, function, type) within a file

Identifies the AST node at a given cursor position (line and column) in a TypeScript/JavaScript file

Extracts JSDoc/TSDoc comments for a symbol (function, type, class, variable). Supports Class.method syntax.

Generates a Mermaid flowchart showing the call graph of functions in a TypeScript/JavaScript file or directory

Finds all functions in a file or package that call the specified function (reverse call graph)

Computes cyclomatic complexity for functions in a TypeScript/JavaScript file

Compares two TypeScript/JavaScript files structurally, reporting added/removed/modified symbols

Detects code smells: long functions, too many parameters, deep nesting, god classes, 'any' casts, non-null assertions

Analyzes TypeScript-specific error patterns: floating promises, empty catches, unsafe type assertions, double assertions

Finds unreferenced unexported symbols (functions, types, variables) within a directory

Finds classes that implement a specified interface - explicit 'implements' plus structural matches, checked by the TypeScript type checker (member types and call signatures, not just names)
