UI5 MCP-First Development

Before writing, modifying, debugging, or fixing SAPUI5 controllers, XML views, or control bindings, you MUST query the UI5 MCP server and apply its guidance.

Tools

Use mcp__ui5__* tools — primarily mcp__ui5__get_api_reference, mcp__ui5__get_guidelines, mcp__ui5__run_ui5_linter, and mcp__ui5__get_project_info.

Workflow

1. Query before coding — call mcp__ui5__get_api_reference for control APIs, or mcp__ui5__get_guidelines for project-level patterns
2. Trust MCP over training knowledge — if guidance conflicts with what you know, follow MCP
3. Run the linter after changes — call mcp__ui5__run_ui5_linter to catch deprecated APIs
4. Prefer the simplest pattern when MCP returns multiple valid approaches

Scope

This skill covers:

• XML views with sap.m, sap.f, sap.uxap namespaces
• Controller extensions (app/**/ext/controller/*.js)
• Model bindings, formatters, event handlers
• Control APIs and property configuration

UI5 Code Standards

• XML views only — no JavaScript views
• sap.ui.define for all modules — no globals
• Async loading: data-sap-ui-async="true"
• i18n for all user-facing text
• No deprecated APIs (jQuery.sap.*, sync loading, sap.ui.getCore())
• Fiori Elements controller extensions must be plain objects (not ES6 classes) — this refers to the ExtensionAPI instance
