What problem does it solve? Navigating an unfamiliar codebase to find where code lives, how modules relate, or what calls a given symbol is slow and error-prone when done by manually grepping files. This Skill provides a structured workflow for answering architecture and code-location questions using a code knowledge graph. ## Core Features & Use Cases - Architecture Overview: Start from graph statistics and community detection to understand high-level module structure before drilling into details. - Symbol and Relationship Tracing: Locate functions and classes with semantic search, then trace callers, callees, and imports to understand dependencies. - Execution Flow Analysis: List and inspect execution flows to understand how code paths run end to end. - Use Case: When asked "what implements the payment retry feature", run a semantic search for the relevant symbols, then use callers_of and callees_of queries to map the full dependency chain. ## Quick Start Ask the AI to give you an architecture tour of this repository and show which modules call the authentication service.
