Comprehensive X3 4GL skill with a self-contained dictionary, syntax guide, project idioms, UI-framework observations, and troubleshooting workflow. Use when Codex needs to explain 4GL constructs, generate or refactor X3 routines, review .src/.tra/.stc files, map help semantics into code, or troubleshoot runtime and authoring issues in X3 4GL projects.
Use the skill's own dictionary first. Treat the mined sources as build-time inputs, not as the primary runtime dependency.
