Fix Pseudo Modules and Implicit Globals

This skill fixes pseudo module access and implicit global issues that the UI5 linter detects but cannot auto-fix because they require understanding proper module import patterns.

Linter Rules Handled

Rule ID	Message Pattern	This Skill's Action
no-pseudo-modules	Deprecated access of enum pseudo module '...'	Import via library module
no-pseudo-modules	Deprecated access of DataType pseudo module '...'	Import via library module
no-implicit-globals	Access of module '...' not exported by library '...'	Import module directly
no-implicit-globals	OData built-in global symbols must not be used implicitly	Import ODataExpressionAddons

When to Use

Apply this skill when you see linter output like:

MyController.js:5:5 error Deprecated access of enum pseudo module 'sap/ui/core/BarColor'  no-pseudo-modules
MyController.js:8:5 error Deprecated access of DataType pseudo module 'sap/ui/core/CSSSize'  no-pseudo-modules
MyController.js:15:5 error Access of module 'sap/ui/unified/DateRange' not exported by library 'sap/ui/unified/library'  no-implicit-globals
MyView.view.xml:20:5 error OData built-in global symbols must not be used implicitly  no-implicit-globals

Background: Pseudo Modules

In UI5, enums and DataTypes were historically accessed as if they were modules (e.g., sap/ui/core/BarColor). These are "pseudo modules" - they don't exist as real files but are resolved at runtime from the library module. In modern UI5, direct pseudo module imports are deprecated.

Fix Strategy

1. Enum Pseudo Module Access

Problem: Importing enums as direct modules.

// Before - triggers no-pseudo-modules
sap.ui.define([
    "sap/ui/core/mvc/Controller",
    "sap/ui/core/BarColor",           // Pseudo module!
    "sap/m/ListSeparators"            // Pseudo module!
], function(Controller, BarColor, ListSeparators) {
    "use strict";

    return Controller.extend("my.app.controller.Main", {
        onInit: function() {
            var color = BarColor.Positive;
            var separator = ListSeparators.All;
        }
    });
});
