AccessibilityUI5AccessibilityMaking a UI usable with a screen reader, with a keyboard alone and without seeing the layout: accessible names on controls, a heading order, landmarks, focus handling and announcements. Target size for a finger is [touch operation](capability:ui5-touch-uis).Agent access to your codeCAPUI5Agent access to your codeLetting a coding agent read the project or the system you actually have, reach its model, its objects and its checks, and act on it. In file-based environments that works out of the box; complex systems need dedicated access capabilities. Whatever the environment, the agent also needs project- and framework-specific context, so it understands the thing in front of it rather than guessing from what it remembers of its training data. The transport is incidental: an MCP server, a language server or a CLI answer the same question, and what differs between them is how much of the real thing the agent can see. Distinct from [MCP servers](capability:mcp-servers), which is a protocol adapter on your own running service, and from [agent guidance](capability:agent-guidance), which is knowledge handed over as files rather than read from the thing itself.Agent guidanceCAPUI5Agent guidancePackaged knowledge you hand a coding agent so it gets a framework right unprompted — skills, rule files, instruction packs. Distinct from agent tooling, which is about building agentic features into your application, and from [agent access to your code](capability:agent-code-access), where the agent reads the real project instead of being handed a file about it.Build and dev-server toolingUI5Build and dev-server toolingServing an app locally and building it for deployment — proxying a backend, transpiling, bundling, and shaping the result for whatever will host it.Data bindingUI5Data bindingKeeping a control and a model in step in both directions, including the formatting, type conversion and validation that sit between the two.DocumentationCAPUI5DocumentationFinding the answer in what has already been written, and writing it where it has not — first-party documentation made searchable by something other than a person scrolling it, including by an agent, and a document of custom code produced from the code itself.Fiori annotationsCAPUI5Fiori annotationsDescribing a service so a Fiori client can render it without hand-written UI code — titles, value helps, hierarchies and visibility expressed as model annotations rather than screen logic.GeneratorsCAPUI5GeneratorsGetting from nothing to a project that runs, and from a project that runs to one that has the piece you just decided you need. Two different moments: the first is a one-time decision about layout, the second recurs for the life of the project.Integrated frontend dev serverCAPUI5Integrated frontend dev serverServing a frontend and its backend services together during development, so they can be reached through one local origin. Serving prebuilt files and integrating a frontend toolchain that assembles resources on demand are different requirements.Key-user adaptationUI5Key-user adaptationChanging a delivered app without modifying it — moving, hiding and adding elements as a layered set of changes that survive an upgrade.LintingCAPUI5LintingCatching in the editor what would otherwise be caught at deploy time, or not at all — problems in source code and models and in the project's configuration, found by rules rather than by review.LoggingCAPUI5LoggingSeeing what a running service did, in a form something can read afterwards — levels, a formatter that suits a laptop and one that suits a log service.Routing and navigationUI5Routing and navigationTurning a URL hash into a view, and a view change back into a URL — so a deep link, a browser back button and a refresh all land where the user expects in a single-page app.TelemetryCAPTelemetrySeeing what a running service did — traces across handlers and database calls, metrics, and correlation that survives an async boundary.ThemingUI5ThemingApplying a consistent visual identity across every control, including the parameters an app may read and the custom themes an organisation may build.TypeScript supportUI5TypeScript supportWriting apps and libraries in TypeScript — the type definitions, the module syntax the loader expects, and the build step that gets from one to the other.UI5 testingUI5UI5 testingProving a UI still works — unit tests over controllers and formatters, integration tests that drive real controls, and end-to-end runs against a served app.Web Components interopUI5Web Components interopUsing standards-based custom elements inside an app, and the question of which control set an app should be built from at all, two concerns that are often answered as one.

@openui5/sap.ui.core@openui5/sap.ui.coreThe OpenUI5 core: the module loader, the MVC runtime, data binding, routing, theming and the test stack, which is everything a UI5 app does before a single community package is added.sap official, ui5

@ui5/mcp-server@ui5/mcp-serverSAP's MCP server for UI5 development: ten tools that scaffold an app or a card, read the project in front of the agent, and run the linter and the manifest validator against it.sap official, ui5
It reads a UI5 project and the framework's own documentation, not a running system or a backend: a question about the service behind the app is answered somewhere else. Node.js v20.17 or v22.9 and above.

UI5/plugins-coding-agentsUI5/plugins-coding-agentsUI5's own plugins for coding agents, three of them: everyday development, modernising a legacy project, and converting one to TypeScript, each installed into Claude Code or GitHub Copilot.sap official, ui5
Guidance, not access: these are instructions handed to an agent, and what the agent can then read of your project comes from [@ui5/mcp-server](artifact:ui5-mcp-server) or the editor. A modernisation workflow that runs autonomously across a codebase is also a thing to point at a branch rather than at main.
