I'm asking this because as I wrote a new CLI tool I picked json as the recommended output format for LLMs. I noticed though that they easily get lost and generally consume a lot of tokens to analyse the output. I'm sure it would work well when the LLM is trained for and already know what to expect, but that doesn't work for a new tool. So, what's the natural language for them?
