Cite from our chat with Claude.ai regarding the issue:

I'm max claude user. I use opus mainly. I am suspecting that at the latest times you became very lazy and stupid model. Before I didn't review your works at all because I trusted for your level. But last 2-3 days I started to find very stupid decisions and implementations. Now, I asked you to review using codex cli mcp one of your implementation and it found real issues then you started to fix plan by yourself. Then I asked you let codex provides the implementation plan and it provided the correct implementation. Now, I am thinking maybe the model is degraded when a user uses claude continuously or claude.ai degrades it when time comes for the next model version release
