gitnexus-refactoring

To safely rename a function across a large codebase, map upstream and downstream dependents, preview graph and AST-based edits via dry runs, and verify affected tests before applying changes.

AST-based code refactoring analyzes the abstract syntax tree to preserve callers and tests when moving files or splitting services. You need it to restructure code while ensuring high-confidence edits and reference integrity.

Preview the impact of extracting a module by running a dry run, which detects affected files and symbols, maps dependency graphs, and provides AST-based edits that require human review before final application.

Yes, you can split a service into focused functions while preserving existing tests by mapping downstream dependents, detecting post-change impacts, and verifying affected processes and tests before applying edits.

Dependency mapping identifies upstream and downstream dependents to detect affected files, symbols, and processes for repository-wide refactoring, recommending targeted tests to verify changes before they are applied.
