What problem does it solve? Understanding an unfamiliar code component requires manually tracing imports, callers, and dependencies across many files. This Skill uses a pre-built knowledge graph to locate a component and its connections, then produces a deep-dive explanation grounded in the actual source code. ## Core Features & Use Cases - Graph-Guided Lookup: Searches the knowledge graph JSON by file path or function name to find the target node's type, summary, tags, and complexity. - Dependency Neighborhood Mapping: Traces incoming and outgoing edges (imports, calls, depends_on, contains) to show how the component connects to the rest of the codebase. - Architectural Context: Identifies which architectural layer the component belongs to and explains its role, internal structure, and data flow in plain language. - Use Case: A new team member asks how src/auth/login.ts:verifyToken works; the Skill locates the node, maps its callers and dependencies, reads the source, and explains the full picture. ## Quick Start Run /understand-explain with a file path or function path like src/auth/login.ts:verifyToken to get a deep-dive explanation of that component.
