codebase-exploration

Specializes in systematic codebase exploration and discovery. Uses advanced search techniques, pattern recognition, and code analysis to quickly understand unfamiliar code, locate specific implementations, map architectural patterns, and answer location-based questions about code.

| "Where is user authentication?" | Search for auth keywords + login patterns | | "How does data flow work?" | Find models, services, controllers pattern | | "Which file handles X API?" | Search endpoints + route definitions | | "Find all database queries" | Search ORM patterns, SQL keywords | | "Locate error handling" | Find try-catch, error classes |

| grep/rg | Text pattern matching | rg "function handleAuth" | | find/fd | File name/path matching | fd -e ts auth | | ast-grep | Code structure matching | ast-grep --pattern "class $NAME" | | LSP tools | Symbol and reference finding | lspfindreferences | | git log | Historical context | git log --name-only |
