I was working on an Android project and needed to add specific vibration patterns for different actions. Our company was maybe a week into our exploration of LLM tools and they still really sucked. I kept getting failures trying to get any thing useful to output. So I dug into the docs and just started doing it all myself. Then I found some Android engineer had named the base functionality Vibrator back in one of the earliest SDKs.
Thee LLM was actually implementing nearly everything, finding the term vibrator, and was then erasing its output.
