In a fresh project that is well documented and set up it might work better. Many issues that Agents have in my work is that the endpoints are not always documented correctly.

Real example that happened to me, Agent forgets to rename an expected parameter in API spec for service 1. Now when working on service 2, there is no other way of finding this mistake for the Agent than to give it access to service 1. And now you are back to "... effect of context size on agent performance ...". For context, we might have ~100 services.

One could argue these issues reduce over time as instruction files are updated etc but that also assumes the models follow instructions and don't hallucinate.

That being said, I do use Agents quite successfully now - but I have to guide them a bit more than some care to admit.
