At least that nominally creates some value at the end of the day. Documentation is the thing everyone wants but no one has time/desire to create. My most recent token heavy task was having an agent write unit tests for coverage on a little graphAPI tool I'd written a bit ago to satisfy SonarQube.
People don't want to read LLM-generated docs though. It'll lack the context to justify why things were designed the way they were, and there's always a risk of hallucination so you still have to verify the documentation's claims, since the person who published it likely did not scrutinize it.
