What steps can reproduce the bug?

Because of the sandbox it often gets confused and cannot figure out things related to databases, kafka and other "network" connected things, even if it's a test database or just locally. It keeps running around in circles because of something in the system prompt related to the sandbox and network access, which prevents it from being efficient at debugging and writing code. It for example often refuses to run tests, especially integration tests, when the sandbox is on and just generally keeps doing weird stuff. It seems there is something about the system prompt that makes it think it just completely have to avoid anything network related including local database calls and it spends a lot of time trying to get around this rather than asking for permission.

What is the expected behavior?
