I just tried vibe coding with Claude (programming.dev)

...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.

I read a lot of these posts that sadly leave out the basic parts: what were your prompts? What does it means in this context 'vibe coding'? Did you create an initial setup, and slowly build up? Did you left wverything to the agent understanding, and just pushed approve or reject? There are multiple levels of quality that depends on the input. Did you get into context rotting? 3d math means vector math, matrices, or what? Given claude has a serious problem from march at least, the way u use it is paramount. In our team we all use claude with copilot ( sadly, that is a business directive ), and while excpetional at finding small relationships in components and microservices, had to build a long list of skills just to be barely usable in a 'star trek' way. The bottom line is that it is that you must be extremely precise when asking. Prompt modeling count a lot. Context build as well. For now, unit tests and data/mocks refactors are working extremely well for me, when i define the tests cases. My agents got to a point where i can safely have small peoperty additions with refactors on multiple repositories at once ( ie: i change the contract on microservice a, microservices b,c,and d are automatically updated ). This last part had to.be built thoug, with memory, engrams, and some fune tuing. It is not always a shit: if not nobody would use it. It is not this revolutionary technology that will make humans obsolete as well ( as they are selling it ).
