I think they meant that your unprompted declaration of having understood the feature, followed by giving no apparent insight into it is odd and something reminiscent of a bot.
Your entire comment could just be “Here’s the quickstart guide: <link>” and literally no useful information would be lost.
A human would topically say: “I spent some time understanding the feature and I think I got it.
<summarized description of the feature or insight/opinion about its implementation>
Here the quickstart: <link>”
Or perhaps you wrote the quickstart? That’s not clear from your wording.
I guess I spend my entire day working with LLM prompts, CoT, etc. so maybe I am without realizing starting to adopt some of the same language patterns. The comment reads normal to me, but I bet so did 'We don’t understand your cost function' for Greg and Ilya.
