What problem does it solve? Navigating a large codebase with plain grep and file reads becomes slow and error-prone when you need cross-file orientation, caller tracing, or change-impact analysis. This Skill builds a local structural index of a Git repository so you can locate definitions, inspect file APIs, and trace dependencies without running any target-project code. ## Core Features & Use Cases - Structural indexing and mapping: Index a repository and get a capped map of directories, hubs, and hotspots derived from a tree-sitter based code graph. - Definition and symbol lookup: Find symbols by exact name or lexical query, and view a file's outline with precise line spans. - Caller and dependency tracing: Trace inbound or outbound edges around a symbol with configurable depth, including edge confidence and endpoint locations. - Use Case: Before renaming a shared validateToken function, trace its inbound callers at depth 2, inspect each caller's contract in the original source, then make the change and run the project's own tests. ## Quick Start Ask the agent to index the current repository and trace the callers of a specific function using the code-navigation skill.
