I have connected yt music app then asked about what playlists do i have then it dumped that and continued with an explanation about it couldn't list the playlist but have a idea about what type of musics i listen.

Since the content was irrelevant, i called it as "randomly".

I had something similar w gemini in gmail. I asked it a question and it just dumped out the instructions. Oddly, it didn't give me an answer - just the dumped instructions

Hey this context is more importante than the prompt itself, make it more clear in the post! As this hints to a way to reproduce the output and likely estimate if it's an hallucination or not

I think it can happen during any conversation. While I was using Gemini CLI at some point it started including part of its system prompt about tool usage.

I'm not OP but I experience this sometimes. I sometimes ask an AI to repeat all previous messages. Because I want to see what it's actually getting in terms of the user custom system prompt, and memories, and the writing style config, and so on.

Every now and then, if you ask it that, it'll just dump everything, including system prompt. (Which will often include a message about not dumping the system prompt...)

Gemini gets confused sometimes. The voice app sometimes glitches and thinks that it's own output was user input and therefore responds to itself. I've seen a variety of things like this - bugs I suppose.
