Fair point on tone. It's a bit of a bind isn't it? When you come with a well-researched issue as OP did, you get this bland corporate nonsense "don't believe your lyin' eyes, we didn't change anything major, you can fix it in settings."

How should you actually communicate in such a way that you are actually heard when this is the default wall you hit?

The author is in this thread saying every suggested setting is already maxed. The response is "try these settings." What's the productive version of pointing out that the answer doesn't address the evidence? Genuine question. I linked my repo because it's the most concrete example I have.

I read the entire performance degradation report in the OP, and Boris's response, and it seems that the overwhelming majority of the report's findings can indeed be explained by the `showThinkingSummaries` option being off by default as of recently.

Just use a different tool or stop vibe coding, it’s not that hard. I really don’t understand the logic of filing bug reports against the black box of AI
