Is Claude good at working with XML prompts, or is XML good at convincing users to write more Claude-able specs? I am intensely skeptical that you could write an XML document describing a nontrivial web application in full detail, but I could easily imagine someone who thinks they have to stripping out important details because they don't really map to XML.

They train it with XML even the system prompts that Claude reads are formatted by it.

I haven't done it professionally, but my understanding is that this kind of work is much more in the second category, where you have to understand the closest approximation to what you want that the LLM can reliably produce or the training won't work at all.
