Returns a compact table-of-contents for the repository 'myorg/myrepo'. Lists all tracked source files with their exported symbol names. ALWAYS call this FIRST before any other tool to understand the repository structure. Use the file paths returned here as input to get_folder_skeleton or get_file_skeleton. Cost: ~10-20 tokens per file — very cheap.

Returns compact AST skeletons for all source files under a given folder path prefix. Use this to understand a module or feature area without reading raw source files. Skeletons include: exports, function signatures, type definitions, and doc comments. Cost: ~50 tokens per file — much cheaper than raw source code. Tip: call get_repo_index first to discover valid folder paths.

Returns the AST skeleton for a single specific source file. The skeleton includes: all exports with signatures, imports, class members, and doc comments. Use this when you need the details of one specific file after narrowing down from get_repo_index. For multiple related files, prefer get_folder_skeleton — it is one round trip.

Searches the entire repository for files that export a specific symbol name. Use this to find where a function, class, type, or interface is defined. Returns: file path, language, kind (function/class/type/etc.), signature, and doc comment. Example: search for 'createClient' to find all files that export a function by that name.

Returns aggregate statistics for the repository 'myorg/myrepo'. Includes: total file count and a breakdown by programming language. Use this to understand the tech stack and scale of the codebase at a glance.
