Yes, it does exactly that. It also sends other prompts like generating 3 options to choose from, prefilling a reply like 'compile the code', etc. (I can confirm this because I connect CC to llama.cpp and use it with GLM-4.7. I see all these requests/prompts in the llama-server verbose log.)
You can stop most of this with
export DISABLE_NON_ESSENTIAL_MODEL_CALLS=1
And might as well disable telemetry, etc:
export CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1
I also noticed every time you start CC, it sends off > 10k tokens preparing the different agents. So try not to close / re-open it too often.
