codanna

Overview

Codanna acts as an X-ray vision for AI coding assistants, enabling them to understand codebases with surgical precision. It provides instant call graphs, semantic search functionality that matches intent rather than just keywords, and full dependency analysis across files. The server is designed for rapid R&D and pair programming situations where traditional LSP tools might be too slow.

After installing, here are 5 things you can ask your AI assistant:

• semantic_search_with_context

  Perform semantic search on code with natural language queries

  Try:Find where we handle errorsTry:Show me authentication functionsTry:Where is the payment processing logic
• search_documents

  Search through indexed documentation and text files

  Try:Search authentication flow docsTry:Find API usage examplesTry:How to configure the database
• call_graph

  Generate call graphs for functions to trace relationships

  Try:Show who calls this functionTry:Find all implementations of this methodTry:Trace dependency from main to utils
• find_implementations

  Find all implementations of a function or method

  Try:Show all implementations of calculateTotalTry:Find who implements this interfaceTry:List all overrides of this method
• dependency_analysis

  Analyze dependencies across the codebase

  Try:What breaks if I change this classTry:Find all dependencies of this moduleTry:Show circular dependencies
• function_definitions

  Find and analyze function definitions

  Try:Find all functions named 'validate'Try:Show function signatures with parametersTry:Find functions that return promises
