Is it the models themselves or the tools around them? There's that patch[1] that floats around for Claude Code that's supposed to solve a lot of these problems by adjusting its tool-level prompts. Also, if it were the models themselves, wouldn't Cursor users have the same complaints (do they? I haven't heard anything but the only Cursor users I talk to are coworkers)?

I think it's more likely they're trying to optimize the Claude Code prompts to reduce load on their system and have overcorrected at the cost of quality.
