> This all started because I was contractually obligated to write unit tests for a codebase with hundreds of thousands of lines of code and go from 0% to 80%+ coverage in the next few weeks - seems like something Claude should do.

Is your client ok with this? Are the tests any good?

If left to its own devices, Claude will resort to writing passable looking BS as tests pretty quickly when the going gets tough e.g. if it has to interface with stateful real world systems and its tests struggle to pass

claude is like an intern, someone has to code review and approve before final delivery imho

While I agree with the sentiment, you are being to generous. Claude is like a new intern every 15..30 minutes, or however long it takes to fill the context. "Oh, I know what is the issue, let me delete this code for now" and proceeds to nuke the fix it spent last context window making. No intern can be that malicious.
