I'm amused at how many hacker news accounts saw this and immediately jumped to the conclusion that you either were using the model wrong or using the wrong model.
ive been regularly seeing this exact reaction online since November 2025, sadly :/

Working on more complex, logic heavy projects with strong performance needs I find the models to be useful but certainly not 'one shot' on pretty much anything. And often incredibly frustrating and genuinely bad code that collapses performance and bloats systems - like what a really bad junior might write.
When I'm working on large standard crud web projects with already decent architecture and a good harness and skills, honestly they work pretty well a lot of the times, the code looks good, does what it needs and fits in with the architectural style.
I really think a lot of hn people just write simple repetitive software, and a small portion works on complex, weird, dense, and novel'ish logic projects. The two obviously don't have the same experiences.
The most telling one is counting function invocations wrong, because that's simply not how models work anymore. They use terminal commands and Python scripts for research like that (if not an LSP, if one took the time to set up their tools most effectively).
Combined with their attitude, I have little doubt that the parent has disabled tool calls, is working in some janky Harness like chat/Duo/Juno, or is using a severely reduced or outdated model.
Yes, so I'll disclose it: I was using Opus 5.5, on medium effort, in Claude desktop, which has full access to my entire repo.
Now everyone can officially lambast me for "using the model wrong or using the wrong model," exactly as you say. But I find it quite interesting that one of the commenters here assumed I was using Opus 4.6, because these mistakes sound like that old version! I'm using the version released just four freaking days ago!
I expect some commenters will now say, "Oh, you should have been using Fable, you old boomer." To them I say: "Yeah, well my employer doesn't allow me to use Fable." And, in jest: "Now get off my lawn."
It's basically impossible at this point to take these people seriously anymore.
My model weights don't change unless I change them.
