I think this is a different use case. The context we're talking about is building software. A GitHub action is really a script. Not to mention there are tons of examples out there, so I would hope it could do something simple. Vibe coding scripts isn't what people are typically concerned about.

Although this is ultimately related. How can you verify that it is working as intended? You admit to not having those skills. To clarify, I'm sure "it's working" but can you verify the "as intended" part? This is the hard part of any coding. Getting things working isn't trivial, but getting things working right takes a lot more time.

  > So the most recent thing that I did

I'll share a recent thing I tried too...

I was working on a setup.py file and I knew I had done something small and dumb, but was being blind to it. So I pulled up claude code and had it run parallel to my hunt. Asked it to run the build command and search for the error. It got caught up in some cmake flags I was passing, erroneously calling them errors. I get a number of prompts in and they're all wrong. I fixed the code btw, it was a variable naming error (classic!).

I've also had success with claude, but it is super hit or miss. I've never gotten it to work well for anything remotely complicated if there also isn't the code in a popular repo I could just copy paste. But it is pretty hit or miss for even scripts, which I write a lot of bash. People keep telling me it is great for bash and honestly guys, just read the man pages... (and use some god damn functions!)
