Here's another example for the kind of task that I no longer do myself but rather hand off to the AI, because it does it so well. My

Let's implement a new option --fib_eff that gets a single value or a range, like 0.9 or 0.7-0.9 , in order to set the fiber efficiencies in the simulation. see fiber_efficiency.md how to do that. set the eff after loading the HDF file, dont modify it. Ranges like 0.7-0.9 are to be interpreted as a random value within that range, uniformly distributed. ask if this was unclear, othweise get crackin and iterate. example command: uv run andes-sim flat-field --band H --subslit slitA --wl-min 1600 --wl-max 1602 --fib_eff 0.5-0.95

As expected, Claude had no problem figuring this out. This the resulting commit. The image above is the ouput of that example command.

I did not have to to type anything else than the prompt above. And in doing that, I needed to get clear for myself what I actually wanted, which is always a good thing to do first. The rest is just typing.

The whole project, a CLI to make simulated spectra, was "vibe-coded" this way, me caring little about the actual code that Claude produced, only taking the occasional glance at it. It is therefore probably not great for a long-term maintained code-base, but it already does what I need it to and I have no intention to take this much further.
