ui5

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.

This skill should be used in any OPA5 task - creating, modifying, extending, debugging, fixing or reviewing an integration test. Use when the user asks to "write an OPA5 test", "add an OPA5 journey", "fix the OPA5 test failure" or mentions OPA5 or its components - opaTest, page object, journey, waitFor.

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).
