In case the author is lurking, you may want to apply the same fix they do in clojure-mcp: https://github.com/bhauman/clojure-mcp/blob/8150b855282babcd...
The insight that team had was that LLMs get confused with parens, but they are excellent at indentation, so if you run parinfer over the LLMs output it will be correct in 99% of cases.
