Claude has definitely gotten stupider (even on the latest Opus).

I used to be able to give it certain commands, and reliably count on it to do the right thing. Lately I give it identical commands and it just starts doing something idiotic, instead of the correct thing (that it did 50 times prior).

To an earlier poster's point, it's probably the model, not the harness, and I understand Anthropic has to make money someday (and they're not now) ... but I'd rather see a visible doubling of price than a secret halving of the capabilities (which seems to be their current plan).

That approach is enshitification.
