Plan and execute a SAPUI5/OpenUI5 version upgrade. Use when the user is bumping the UI5 version in manifest.json, ui5.yaml, package.json, or an existing UI5 app and wants to identify deprecations in use, fixes that remove local workarounds, relevant new features, manifest/schema issues, and API replacements. Combines this server's `ui5_version_diff` tool with SAP's `@ui5/mcp-server` tools.

Use this skill WHENEVER the user wants to create, generate, draw, design, or author an SAP architecture diagram, SAP BTP solution diagram, SAP Cloud Foundry / Kyma / ABAP environment landscape, Cloud Connector topology, SAP S/4HANA landscape, Fiori / SAP Build / Joule architecture, subaccount diagram, MCP-to-SAP deployment diagram, XSUAA auth flow, Principal Propagation diagram, or anything that should match the visual style of https://architecture.learning.sap.com / SAP Architecture Center. Input is a text description of the topology; output is a pixel-polished `.drawio` file (and optionally a PNG export) that matches the canonical SAP Horizon look — correct palette, Helvetica typography, 10-px grid, SAP BTP service icons, straight arrows, no clipped labels.

Evidence-based assessment of whether an SAP API/interface usage scenario aligns with the SAP API Policy (v.4.2026a). Use whenever someone asks whether a way of calling SAP is allowed/compliant — e.g. Published API vs internal/private/"confidential" API status, "Documented Use", whether a third-party tool / iPaaS / middleware / RPA bot / AI agent / MCP server may call SAP APIs, agentic or generative-AI access to SAP, bulk data extraction or replication into a lake/warehouse, custom Z/Y OData or RFC/BAPI wrappers and Clean Core, ADT/developer-tooling boundaries, ODP-RFC and other "not permitted" interfaces, partner Integration Certification, or RISE integration remediation. Trigger even when the policy is not named, e.g. "are we allowed to…", "is it compliant to…", "can we connect X to SAP…", "will this break under the new API policy". Produces a sourced technical assessment with a confidence level — explicitly NOT legal advice and NOT a final SAP compliance decision.
