It's often unnecessarily verbose. If you read a comment and glance at the code that follows, you'll understand what it is supposed to do. But the comment you're giving as an instruction to an LLM usually contains information which will then be duplicated in the generated code.

I see. Might still be good to have a verbose comment than no comment at all, as well as a marker of "this was generated" so (by the age of the code) you have some idea of what quality the LLM was in that year and whether to proofread it once more or not

External comments are API usage comments. LLM prompts are also implementation proposal.

Implementation comments belong inside the implementation, so they should be over if not deleted.
