Mixed result with Claude Code - Does not really understand IBM ACE

Hi, I played with Claude Code, like everyone, and did have mixed results. Private: Websites, server side PHP, client side JavaScript. Result: Amazing, incredible, it understands everything, maintenance goes from hours to minutes. Work: Message flows in IBM ACE: Result: Bad, in ESQL it does not understand the difference between a Database node and Compute node, generated ESQL contains many errors, and so on. The IBM ACE world (previous named IBM IIB and IBM WMB) does not have a big Internet presence, so I understand it is not really trained on it. So, how to fix this? How to get Claude Code as good on ACE as it is with PHP and JavaScript?
