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.

The reason you kept going around in circles and reintroducing bugs you already got rid of is because LLMs don’t remember things. Every time you tell it something it tells it the entire conversation again so it has all the parts. Eventually it runs out of room and starts cutting off the beginning of the convo and now the llm can’t ‘remember’ what it was you were even talking about.

Kind of, but it really depends on the workflow. Simple 3d math does not extend to a codebase that is impacted by context window

For that you can ask to update a documentation/status file on every update. You can manually add the goal and/or tasks for the future.

With that, I improved my success a lot even when starting new sessions (add in the instructions file to use this file for reference, so you don't have to remind every time)
