SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Search inefficiencies in large codebases by enabling targeted navigation, pattern discovery, and context-aware tracing of functions and dependencies.

Core Features & Use Cases

  • Semantic search across codebases to find conceptual matches for features or bugs
  • Grep-style pattern matching to locate exact strings, functions, or identifiers
  • AST-based navigation to understand code structure and dependencies
  • Use cases include tracing function calls, locating legacy code, and analyzing code changes over time

Quick Start

Provide a concise query describing the target (e.g., a function name or pattern) and request a codebase search to locate relevant definitions and usages.

FAQPage Schema
How do I search for function definitions and trace dependencies across a large multi-language codebase?▼

To search a large multi-language codebase, use semantic search, grep-style pattern matching, and AST-based navigation to locate definitions and trace dependencies. This approach delivers precise results by understanding code structure within Git-tracked repositories.

Can I use semantic search to find conceptual matches for features or bugs in legacy code?▼

Yes, semantic search finds conceptual matches for features or bugs in legacy code. It identifies code patterns and traces functions across large repositories, enabling targeted navigation and context-aware discovery without requiring exact string matches.

What is the best way to navigate code structure and dependencies using AST analysis?▼

The best way to navigate code structure is using AST-based navigation, which parses abstract syntax trees to map dependencies and locate definitions. It operates within Git-tracked codebases to deliver precise structural analysis across multi-language projects.

Does codebase search work with Git-tracked repositories to analyze code changes over time?▼

Codebase search works directly with Git-tracked repositories to analyze code changes over time. It combines grep-style pattern matching and AST-based navigation to locate legacy code and trace function calls within version-controlled projects.

How do I locate exact strings and identifiers using grep-style pattern matching in a large repository?▼

To locate exact strings and identifiers in a large repository, use grep-style pattern matching. It targets specific function names or identifiers to deliver precise results, operating within Git-tracked codebases for accurate code navigation.

When should I not use semantic search for code navigation in multi-language projects?▼

Semantic search is not ideal for locating exact string identifiers or simple patterns in multi-language projects. Use grep-style pattern matching for precise string searches, as semantic search focuses on conceptual matches rather than exact identifier retrieval.
