I asked Gemini to format some URLs into an XML format. It got halfway through and gave up. I asked if it truncated the output, and it said yes and then told _me_ to write a python script to do it.
On the other, truncating my dataset halfway through is nearly as worthless as not doing it at all (and i was working with a single file, maybe hundreds of kilobytes)
I inadvertently made a stronger yes-man.
