I was recently reviewing commits to a dependency and found meta-information which included LLM prompts. One of which was "go look at the code of <other repository> and generate $foo". That *is* useful, since, as these recommendations state in point #9, that makes the LLM's output be affected by the license of that other repository.

(I am now in the process of replacing the tainted dependency with something else and have pinned it to a non-tainted version in the meantime.)
