What problem does it solve? Understanding an unfamiliar codebase is slow and error-prone when done by manually reading files. This Skill answers questions like "How does authentication work?" or "What calls this function?" by querying a GitNexus code graph of indexed symbols, execution flows, and functional clusters instead of guessing from raw source. ## Core Features & Use Cases - Index freshness verification: Compares the indexed commit against git rev-parse HEAD before querying, so answers are not based on code that no longer exists. - Concept-to-flow discovery: Uses gitnexus_query to find execution flows (e.g., CheckoutFlow, LoginFlow) related to any concept you ask about. - 360-degree symbol inspection: Uses gitnexus_context to show incoming calls, outgoing calls, and process membership for any symbol. - Use Case: You join a project and need to understand payment processing. The Skill checks index freshness, queries for "payment processing", traces CheckoutFlow step by step, then points you to the exact source files for implementation details. ## Quick Start Ask the assistant to explain how a specific feature works in this repository, for example "How does the authentication flow work?"
