UI5 development best practices and coding standards derived exclusively from official SAP UI5 guidelines. Use when writing UI5 applications to ensure modern, maintainable code following SAP standards. Covers: async module loading (sap.ui.define, ES6 imports, core:require), ComponentSupport initialization, data binding with OData types, i18n management, CSP compliance (no inline scripts), TypeScript event types (UI5 >= 1.115.0), MCP tooling (get_api_reference, run_ui5_linter), CAP integration patterns, and form creation rules (never SimpleForm, always Form with ColumnLayout).
MUST be loaded before any UI Integration Cards (also called UI5 Integration Cards) task — creating, modifying, validating, previewing, or reviewing a card, its `manifest.json`, its Configuration Editor (`dt/Configuration.js`), or any analytical chart configuration. Provides the official guidelines, validation rules, supported chart types, and Configuration Editor patterns.
Use when the user asks to "write a QUnit test", "fix a failing QUnit test", "add a QUnit module", "modernize QUnit tests", "migrate from QUnit 1", or mentions QUnit-specific constructs such as assert.async, nextUIUpdate, Core.applyChanges, sinon sandbox, asyncTest, or QUnit.module. Covers coding standards for OpenUI5/SAPUI5 unit test files: const/let over var, arrow functions over .bind(this), async/await over assert.async(), assert.expect() in every async test, sinon.createSandbox(), descriptive test names, beforeEach/afterEach module isolation, nextUIUpdate vs Core.applyChanges rules, try/finally teardown in helpers, QUnit 1 to QUnit 2 globals migration, and non-ASCII character avoidance.
UI5 table best practices for freestyle applications. Use when creating/troubleshooting any table: sap.m.Table (ResponsiveTable), sap.ui.table.Table (GridTable), TreeTable, SmartTable, or sap.ui.mdc.Table. Covers control selection matrix, mandatory rules, common errors, and per-control API guidance.
