Feature Envy.

A method accesses the data of another object more than its own data.

##Signs and Symptoms

A method accesses the data of another object more than its own data.

##Reasons for the Problem

This smell may occur after fields are moved to a data class. If this is the case, you may want to move the operations on data to this class as well.

##Payoff

Less code duplication (if the data handling code is put in a central place).
Better code organization (methods for handling data are next to the actual data).

For AI agents

Use CodeBust in your coding agent

Give your AI coding agent this catalog as tools — so it can name the smell, find the static-analysis detectors, and apply the right refactoring or pattern while it writes code, instead of guessing.
