...and I still don't get it. I paid for a month of Pro to try it out, and it is consistently and confidently producing subtly broken junk. I had tried doing this before in the past, but gave up because it didn't work well. I thought that maybe this time it would be far along enough to be useful.

The task was relatively simple, and it involved doing some 3d math. The solutions it generated were almost write every time, but critically broken in subtle ways, and any attempt to fix the problems would either introduce new bugs, or regress with old bugs.

I spent nearly the whole day yesterday going back and forth with it, and felt like I was in a mental fog. It wasn't until I had a full night's sleep and reviewed the chat log this morning until I realized how much I was going in circles. I tried prompting a bit more today, but stopped when it kept doing the same crap.

The worst part of this is that, through out all of this, Claude was confidently responding. When I said there was a bug, it would "fix" the bug, and provide a confident explanation of what was wrong... Except it was clearly bullshit because it didn't work.

I still want to keep an open mind. Is anyone having success with these tools? Is there a special way to prompt it? Would I get better results during certain hours of the day?

For reference, I used Opus 4.6 Extended.

This sounds on par for all the AI I have been dealing with. I find it works best if you give it a lot of rules, then treat it like a 12 year old and expect wild mistakes for anything more complicated than a simple calculator. I work primarily with Gemini and have it build simple HTML/CSS and it's infuriating how many times I have told it to use &amp ; instead of &.
Now every time it does anything, it's always telling me how it included the correct ampersand. It can't tell me why it screwed up like 5 times prior, it just makes up some BS and apologizes profusely.
The more rules you give it, even if it ignores them sometimes, the better.

In my view it’s about quality and not quantity of the AGENTS/CLAUDE.md

My experience is that starting with what i dont want and the what i do works best. «never rely on training for API documentation, use context7» «don’t use ls/find/grep for symbols, use serena»

Not the best examples, but but.
