Use this skill whenever the user wants to work with FileMaker script XML or custom function XML. This includes: generating FileMaker XML from a description, pseudocode, or script steps; analysing or reviewing existing FileMaker XML for errors or silent-failure risks; converting scripts between formats; or any task where the output must be paste-ready XML for the FileMaker Script Workspace or Manage Custom Functions dialog. Trigger any time the user mentions FileMaker scripts, fmxmlsnippet, Set Variable XML, script step XML, custom function XML, or asks to produce XML that can be pasted into FileMaker. Always use this skill — do not attempt FileMaker XML tasks from memory alone, as the format has undocumented paste-handler rules that cause silent failures without this reference.
