Migrate all icon usage in the skill directory from @remixicon/react
and custom SVG components to Tailwind CSS icon classes (i-ri-*, i-custom-*).
Update MenuItem API to accept string class names instead of React.ElementType.
Implement ReadOnlyFilePreview to render sandbox files by type
(code, markdown, image, video, SQLite, unsupported) using existing
skill viewer components with readOnly support. Add
useSandboxFileDownloadUrl and useFetchTextContent hooks for data
fetching, and generalize useFileTypeInfo to accept any file-like
object.
Enhance getFileIconType to accept an extension parameter and cover all
13 FileAppearanceTypeEnum types using an O(1) Map lookup. Update all
call sites to pass the API-provided extension for accurate icon display.
- Add guards in tool-block component to skip metadata read/write when Start tab is active
- Add guard in tool-picker-block to prevent writing tool config to Start tab
- Add guard in use-sync-tree-with-active-tab to skip tree sync for Start tab
Remove the Office file placeholder that only showed "Preview will be
supported in a future update" without any download option. Office files
(pdf, doc, docx, xls, xlsx, ppt, pptx) now fall through to the generic
"unsupported file" handler which provides a download button.
Removed:
- OfficeFilePlaceholder component
- isOfficeFile function and OFFICE_EXTENSIONS constant
- isOffice flag from useFileTypeInfo hook
- i18n keys for officePlaceholder
This simplifies the file type handling to just three categories:
- Editable: markdown, code, text files → editor
- Previewable: image, video files → media preview
- Everything else: download button
Move activeTabId and fileMetadata reads from selector subscriptions to
getState() calls inside the callback. These values were only used in the
insertTools callback, not for rendering, causing unnecessary re-renders
when they changed.
