Hi @MarkJSchwab,
I'm not informed about a specific skill for agents to use JMP. However since JMP 19.0, the JMP Scripting Index has been written online on GitHub so that coding agents may learn and better use the JSL Syntax: https://github.com/JMP-LLC/JSL-Scripting-Index-Website
You may also be interested by this discussion JSL scripting with AI helpwhere @OctoAvgJumper share his JSL Claude Skill.
Hope this answer will help you,
