What problem does it solve? Debugging unfamiliar code often means manually grepping for error messages and guessing call chains. This Skill turns debugging into a structured investigation by querying a code knowledge graph to find where errors originate, who calls a suspect function, and how execution flows reach the failure point. ## Core Features & Use Cases - Error-to-Source Tracing: Search for error text or symptoms, then inspect callers and callees of suspect functions to locate the root cause. - Execution Flow Analysis: Read process resources and run Cypher queries to trace call chains, including a shortest-path trace between two symbols. - Regression Impact Checks: Use change detection to see what recent edits affect, helping diagnose regressions. - Use Case: A payment endpoint returns 500 intermittently. Query for the error handling flow, inspect the suspect validation function, discover it calls an external API without a timeout, and confirm the root cause in the source. ## Quick Start Ask the agent to trace why a specific function or endpoint is failing using the GitNexus debugging workflow.
