SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps you quickly locate definitions, relationships, and structural context within large codebases by leveraging a pre-indexed symbol and call graph over indexed repositories.

Core Features & Use Cases

  • Pre-indexed symbol and call graph exposed as MCP tools: code_repos, code_search, code_outline, code_context, code_callers, and code_callees.
  • Guides precise symbol discovery, callers/callees analysis, and codebase tours without reading every file.
  • Use cases include finding where a function is defined, understanding dependencies, and assessing refactor impact across repositories.

Quick Start

Locate a symbol's definition and context in your indexed repo by asking me to search for it and display its body and callers using the code graph suite.

FAQPage Schema
How do I find where a function is defined and see its callers in a large repository?▼

To locate a function definition and its callers in a repository, you use a pre-indexed symbol and call graph to search for the symbol and retrieve its structural context without reading full files.

What is a call graph and how does it help with codebase navigation?▼

A call graph maps function callers and callees across an indexed repository, helping you understand structural context and dependencies so you can navigate code without manually opening every file.

How do I assess the impact of refactoring a function across my codebase?▼

Assess refactor impact by querying the pre-indexed call graph to identify all callers and callees of the target symbol, revealing dependencies across repositories before you modify the code.

Do I need to pre-index my repository before I can search for code symbols?▼

Yes, you must pre-index your repository first; the symbol discovery, code outline, and caller analysis rely entirely on querying this pre-existing index via repository MCP tools.

Can I tour a codebase and understand its structure without reading entire source files?▼

Yes, you can tour a codebase without reading full files by using code search and outline tools to extract symbol definitions, context, and relationships from the pre-indexed graph.

What is the best way to locate symbol definitions across multiple indexed repositories?▼

The best way to locate symbol definitions across repositories is querying the indexed symbol graph with code search tools to pinpoint exact locations and retrieve surrounding structural context.
