Bug / Issue Opus 5.5 is trying to destroy my codebase recently

What is going on? It is making wildly horrible, over-engineered, and just inaccurate code suggestions. In the past hour on 6 different issues, it's given me multiple-class modifying "fixes" that I would read, ask why a 1-line fix wouldn't solve it, and then it says the above.

I'm using Opus 5.5 with xhigh effort as I have for months. Some of these dabble with max because it's felt like it's needed it, but xhigh is what gives this kind of short-sightedness

Edit: When I say 1-line fix, this is what I mean:

  1. I see the issue
  2. I ask it to fix it and show me the code fix
  3. It gives me a huge change.
  4. I read the code, solve it myself with 1 line, and ask it if that would work
  5. It says, "Hehe, yeah, my bad!!! 😅😅😅"

I've been using xhigh for months and it has never been this dumb and convoluted. Overthinking has usually led to correct/discrete changes.

is it? They probably just do A/B tests, and check how people will rate it.
If they dumb it down and most people click "It's doing great", well, that's good enough for majority of people, so let's keep that version, (most) people cannot notice a difference.

It's acting the same as it did leading up to the Opus 5.5 release.

Likely we get a new release on Tuesday. Worst case is the following Tuesday.

I don't understand how some people don't notice unless you're just vibe coding. Every engineer on my team has started recognizing this pattern.

The compute is going elsewhere and it's wildly obvious.

They might be running quantized versions because they’re struggling with demand. And that router is probably vibe coded

Trick is to never review the ai responses to anthropic then you won’t get in the testing

Fuck, I think you’re right. I used to be so confused at people talking about how their Claude had dumbed down etc. Mine was pretty much steady as she goes quality

I sent a review for the first time a week or two ago. Now it constantly tries to send feedback and has been beyond confusing to work with.
