What problem does it solve? Orienting in an unfamiliar or large codebase usually means grepping around and reading files at random. This Skill produces a ranked focus map of the files and symbols an architecture actually depends on, each with a file:line citation, so you read only what matters before making a change. ## Core Features & Use Cases - Ranked focus map: Extracts the load-bearing symbols of a project with file:line citations and evidence types, using CodeGraph when installed or a dependency-free builtin extractor (regex AST plus ripgrep cross-file references) otherwise. - Flexible seeding: Scan the whole project, seed from specific changed files, or seed from everything changed since a git ref to assess the blast radius of a diff. - Use Case: Before refactoring a module you have never read, run the focus map to see who calls it and what it calls, then open only the cited locations instead of scanning the entire tree. ## Quick Start Ask the agent to run a code-understand focus map on the current project and explain which files are load-bearing before making your planned change.
