Moreover, it helps document whether or not there could be issues with licensing for LLM generated code--just in case a future lawsuit brings any of the generated outputs into question as off-the-shelf/hosted LLMs trained via a number of unknown inputs (Reddit, Repology, Stack Overflow) which have different licenses with different advertising/disclosure requirements. The only LLMs that one can reliably claim are "license poisoning free" require the end-user to do their own training on specific materiel (many closed-source models and open-source models currently fail this requirement).

In LLDB, I've been using `Assisted-by: Claude` and `Assisted-by: GPT` for last few months and no lldb reviewers pointed it out so far. I read the AI policy document, but they don't seem to have consensus what to document (e.g. cli tool used, full model name, effort (light/medium/high/extra high/etc), subscription vs API credit).
