I don't even know what to respond/what this is asking.

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.
