According to the guide, in the company's tests on small programming tasks, if the prompt says nothing about the owner, or presents the code as someone else's, the model tends to add to what exists even if it duplicates code. If it is told it is the long-term owner and maintainer, it merges the repeated code into a shared function in around 75% of runs, compared with under 10% without that sentence. The figures come from the company itself.
The guide also warns of the price: output tokens rose by between 70% and 80%, the model made changes nobody had asked for (mostly tests and documentation) and occasionally altered the behaviour of a function. For that reason it recommends not using the sentence when the code belongs to the user and the aim is to touch as little as possible, and checking the summary of changes, which may leave out small modifications.
For anyone building educational apps with agents, the use is to decide, case by case, whether they want an assistant that respects the existing structure or one that improves it.
