What problem does it solve? Understanding a large or unfamiliar codebase is slow when you have to read files one by one. This Skill uses a code knowledge graph to answer structural questions—where a function is called, which modules exist, how execution flows—without manually grepping through the repository. ## Core Features & Use Cases - Architecture Discovery: Get codebase statistics, community/module overviews, and high-level architecture before diving into details. - Relationship Tracing: Find callers, callees, and imports of any function or class, and inspect execution flows end to end. - Token-Efficient Exploration: Retrieve minimal context for a task first, targeting completion in five or fewer tool calls. - Use Case: Before refactoring a shared utility, use the graph to list every caller of the function and read the relevant tests, so the change does not break downstream code. ## Quick Start Ask the assistant to explore this codebase and show which modules call the authentication service.
