Develop custom plugins for Univer (spreadsheet/document/presentation engine). Use when writing a plugin, registering commands/mutations/operations, extending Facade API classes (FUniver, FWorkbook, FWorksheet, FRange), adding toolbar buttons or context menus, binding shortcuts, or listening to workbook/sheet/cell events. Triggers include 'write a plugin', 'custom command', 'extend FRange', 'toolbar button', 'shortcut', 'menu item', 'Facade extension', or any plugin development error.
