Gemini weirdly messes things up, even though it seems to have the right information - something I started noticing more often recently. I'd ask it to generate a curl command to call some API, and it would describe (correctly) how to do it, and then generate the code/command, but the command would have obvious things missing like the 'https://' prefix in some case, sometimes the API path, sometimes the auth header/token - even though it mentioned all of those things correctly in the text summary it gave above the code.

I feel like this problem was far less prevalent a few months/weeks ago (before gemini-3?).

Using it for research/learning purposes has been pretty amazing though, while claude code is still best for coding based on my experience.
