class-boundary-refactor-heuristics

To choose class boundaries for orchestration-heavy logic, apply heuristic guidelines to evaluate whether logic belongs in dedicated classes, module-level functions, or interfaces, ensuring explicit ownership and clear control flow.

The best way to refactor a service class mixed with utility logic is to follow a restructuring playbook that separates orchestration responsibilities from utilities, establishing explicit responsibility boundaries for better maintainability.

You need to restructure code using class boundary heuristics when working with mid-to-large scale codebases that suffer from mixed orchestration and utility logic and require explicit responsibility separation for clarity.

Separating orchestration and utility logic improves code maintainability by establishing explicit ownership and control flow boundaries, which prevents tangled dependencies and makes complex modules easier to understand and modify.

A limitation of using heuristics for class boundary refactoring is that guidelines are best suited for mid-to-large scale codebases needing explicit responsibility separation, and may be excessive for smaller, simpler modules without orchestration-heavy logic.
