refactor

To break down monolithic files, analyze their responsibilities to identify split points, generate focused files, update dependent imports, and create tests for new components to improve maintainability.

Modularize a monolithic codebase by identifying valid split points, generating focused files, automatically updating dependent imports, and generating missing tests for the new components to maintain coverage.

When refactoring code, components should be under 150 lines and services under 300 lines to guide orchestration, ensuring files remain focused, modularized, and testable.

You need to refactor a monolithic module when complex files become difficult to maintain, requiring stepwise decomposition into focused pieces to improve readability and enable test coverage.

Update imports automatically after splitting a large code file by planning the split with new file names, then generating focused files while enforcing consistency across dependent imports.

Code decomposition works for monolithic modules, services, and utilities, applying stepwise decomposition and test coverage to break complex files into focused, testable pieces.
