This is really interesting: "Humans hate writing nested JSON in the terminal. Agents prefer it." Are others seeing the same thing? I've just moved away from json-default because agents were always using jq to convert it to what I could have been producing anyway.

In my experience agents struggle with escape sequence nesting as much as humans do. IMHO that is one well-paved road to RCE via code injection.
