I'm in a similar situation and I would recommend you use it in a way that will be sort of similar to malicious compliance. Use it for work by asking questions and not allowing it to do any file changes. So instead of pointing it to your repo and saying - implement this, ask it to create a doc describing all the arch, draw diagrams and use it to better understand the project or a specific part. Then use it to more easily implement your work. It requires tremendous discipline and it doesn't help that Claude will sneakily attempt to do work for you and you will need to fight it. But no one can say you didn't use it. It's not perfect, but gives you wiggle room.
