Drive and inspect the Umbraco backoffice reliably with Claude-in-Chrome browser automation. Use this WHENEVER you are about to use the mcp__claude-in-chrome tools against a running Umbraco backoffice — navigating sections, clicking tree items, filling forms, opening/closing modals, or visually verifying a backoffice extension (property editor, dashboard, workspace, tree, section, menu). The backoffice is Lit/web-components with open shadow DOM and modals that render off-screen, so the built-in find/read_page tools see nothing and screenshots lag behind the live DOM. This skill provides a shadow-DOM-piercing JS helper toolkit plus a navigation playbook so you read state from the DOM instead of guessing from pixels. Trigger even when the user only says "open the backoffice", "test the extension in Umbraco", "click through the backoffice", "log in and check it works", or "take a screenshot of the editor in Umbraco".
