Ask HN: Has Claude Code degraded intelligence?

Last week or so, I have been noticing Claude Code has been significantly challenged in keeping its stuff together. On a Max plan, using Opus 4.6 with thinking in Chat window (I use code as well, but this is just an example), asked it create a web page that spits out a few different layouts/designs and its a single page web page, asked it to add ai to generate new designs.

It kept messing up aspect ratio, and forgets to add the AI feature, I know what you are thinking, may be the prompts are off... but its like 'oh I forgot to add the AI feature, let me add it' and then no 'AI Feature' in its output.

Driving me nuts, figured I would ask here to see if its just me or more people are seeing noticeable degradation of their experience recently...
