Why Manager and Processor Classes Are Refactoring Signals
Use vague class names as code-smell signals, then narrow responsibilities and right-size layers without denying necessary transitional design.

Open a class named Processor and look at its methods. It may add and remove likes, update data, search, and perform unrelated CRUD. The name accepts all of those jobs because it promises almost nothing. Manager and Handler can hide the same problem.
Start with the method names inside one vague class
A Reader suggests reading. A class dedicated to modification can be named for that action. If a Handler only modifies data, Modifier says more. If a Processor contains one coherent action, name that action. If it contains many actions, changing the suffix will not help; the responsibilities need to be split.
The vague name is therefore useful evidence. It makes an unsettled responsibility visible instead of pretending the design is complete. A class may honestly be in that state while the team learns what it should own. The danger begins when the temporary container becomes the normal place for every new behavior.
Search the whole repository and judge the pattern
One ambiguous class can be a controlled intermediate step. Twenty processors, or a project where every feature has its own manager, suggest a design habit. Broad containers accumulate CRUD and search because each new method still appears compatible with the name. The pattern points toward classes with several responsibilities rather than one awkward naming choice.
The same search can expose an oversized layer. A small project may have adopted four layers in anticipation of later business complexity. While the software remains simple, the extra slot has no clear work, so processors and handlers appear merely to satisfy the structure. The team can shrink the layer or use it only where coordination actually needs it.
Do not ban the words. Open every match and ask whether the name predicts the methods, whether the class should be split, and whether the layer itself has earned a place. A few deliberately visible intermediate classes can be managed. A repository full of them says that unclear responsibility has spread beyond a temporary state.
