#2Neat, I'm in a similar state of believing the tech is currently in a state that's actually useful while also understanding why the skeptics find it infuriating instead.
( p.s. Tell claude that when quickly pressing keys with a mouse that there is audible clipping. This doesn't seem to happen when using the keyboard. )

#3I found an interesting bug:
https://webpiano.jcurcioconsulting.com/play/fvT2WvzCT1SybhNp...
If I'm playing a quick pattern like this and holding down some bass note, depending on where the pattern starts, the middle two notes will become "synchronized" and play/get recorded at the same time. In my example, the top 4 notes work fine, but shifting down by one note causes the bug. I also switched between holding the bass not and not for demonstration. I assure you my fingers aren't doing anything different, I messed around with this for a while.
edit: got a better recording: https://webpiano.jcurcioconsulting.com/play/b4qautCGQpQjA6wq...
2nd edit: I thought this had to do with the "groupings" of keys but even the middle 4 that are grouped together show this behavior: https://webpiano.jcurcioconsulting.com/play/5XuIskeJNQQaiC7h...

#4> This alone gave me 90% of the finished product
The Claude the industry needs is one that responds to that prompt with questions about scope and intent, and challenges its only-suitable-for-tutorials design ideas rather than obediently delivering a "90% finished product".
10 years ago, this basically marks the difference between hiring some dude on Fiverr for $400 and an actual engineer or agency who might help you figure out what the heck you're trying to do and point you in some sane direction towards it.
I appreciate this article for sharing what kind of experience people can expect from Claude right now, but it mostly demonstrates that code assistants remain most useful in the hands of experts who are careful what to ask for, and largely misleading and slop-amplifying for people who don't.

#5This might not exactly be the place for it but what I struggle with regarding Claude Code is that it doesn't seem to listen to me. I will give it a specific example of code to use as a guide and it just wants to start searching the code base for similar patterns instead of just using the example that has everything it should need. I know claude.md can help but I am not having much luck with a large .NET project using internal nuget packages. I am able to get results decently well but this is a repeated problem I have and if I am not careful, it will blow through my limits.

Claude Code's Plan Mode increasingly does a (small-scale) version of this - it will research your codebase and come back to you with a set of clarifying questions and design decisions before presenting its implementation plan.

I definitely don't think I'd be willing to hand it my day job's codebase and walk away. But I feel a lot more comfortable throwing it very specific tasks and questions, then manually vetting the results. Over time I may be a little more willing to give it bigger chunks or give a more cursory code review on what it generates.
If I come back to it to look to add polish (and fix mobile) that'll be a prompt I'll throw at it as well.

I've found the most useful prompt tip is to add to the end of every prompt:
"Ask questions for clarification as needed."
Claude will then present a list of questions I answer, either directly, or sometimes those prompt more thought or questions from myself.
Either way, that statement helps escape the assumption that I just want some slop reaching the goal in the quickest way possible.

It'd be an interesting follow up to have one of my kids give me prompts to make the same application and see how well it does. As in, when it doesn't save and they say "it's not working." How would it react and try to problem solve.

Do you use plan mode? Do you link specific files as reference using @? Those two alone make a big difference for me.
