Replace the tree-filtered search with a flat list that shows icon + name
on the left and parent path on the right, matching the Figma design.
Clicking a file opens its tab; clicking a folder clears the search and
reveals the folder in the tree.
Enable PDF files to be previewed directly in the file content panel
instead of showing as unsupported files requiring download. Uses the
existing react-pdf-highlighter library with zoom controls and keyboard
shortcuts (up/down arrows).
Add a unified isPreviewable flag to useFileTypeInfo that guards against
rendering binary files as text in both skill artifacts and variable
inspect artifacts preview. Upgrade extension arrays to Sets for O(1)
lookups.
Add import skill modal that accepts .zip files via drag-and-drop or
file picker, extracts them client-side using fflate, validates structure
and security constraints, then batch uploads via presigned URLs.
- Add fflate dependency for browser-side ZIP decompression
- Create zip-extract.ts with fflate filter API for validation
- Create zip-to-upload-tree.ts for BatchUploadNodeInput tree building
- Create import-skill-modal.tsx with drag-and-drop support
- Lazy-load ImportSkillModal via next/dynamic for bundle optimization
- Add en-US and zh-Hans i18n keys for import modal
Backend returns extensions with a leading dot (e.g., `.png` from
`os.path.splitext`), causing binary/media files to be misclassified
as text since they didn't match the dot-free extension lists.
Introduce prepareSkillUploadFile utility that wraps markdown file content
in a JSON payload format before uploading. This ensures consistent handling
of skill files across file upload, folder upload, and drag-and-drop operations.
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.
Switch from whitelist to blacklist pattern for determining editable files.
Files are now editable unless they are known binary types (audio, archives,
executables, Office documents, fonts, etc.), enabling support for any
runtime-generated text files without needing to add extensions one by one.
Implement unified drag system that supports both internal node moves
and external file uploads with consistent UI feedback. Uses native
HTML5 drag API with shared visual states (isDragOver, isBlinking,
DragActionTooltip showing 'Move to' or 'Upload to').
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
- Add constants.ts with ROOT_ID, CONTEXT_MENU_TYPE, NODE_MENU_TYPE
- Add root utilities to tree-utils.ts (isRootId, toApiParentId, etc.)
- Replace '__root__' with ROOT_ID for consistent root identifier
- Replace inline 'blank'/'root' strings with constants
- Use NodeMenuType for type-safe menu type props
- Remove duplicate ContextMenuType from types.ts, use from constants.ts
- Extract useFileOperations hook to hooks/use-file-operations.ts
- Move tree utilities to utils/tree-utils.ts
- Move file utilities to utils/file-utils.ts (renamed from utils.ts)
- Remove unnecessary JSDoc comments throughout components
- Simplify type.ts to only contain local type definitions
- Clean up store/index.ts by removing verbose comments
