Add useExistingSkillNames hook that derives root folder names from the
cached asset tree via TanStack Query select, then use it to show an
"Added" state on hover for already-present skills and block re-upload.
Pass disabled/loading props to TemplateCard declaratively from
loadingId state. All cards are disabled while any upload is in
progress, and the active card shows a loading spinner. Remove the
imperative pointer-events overlay in favor of native button disabled.
Replace custom search input with SearchInput component (built-in clear
button) and add 300ms debounce. Fix template card: use Tailwind token
for icon background, fix Badge to use children with badge-s class and
uppercase, match empty-tag fallback height to badge size.
Remove unused categories (Search, Security, Analysis) and add
real ones (Document, Design, Creative). Consolidate xlsx tags to
Document/Productivity and webapp-testing to Development only,
eliminating orphan tags with single-skill coverage.
Use useRef for batchUpload and emitTreeUpdate to remove unstable
dependencies from useCallback, preventing unnecessary memo invalidation
on all 16 TemplateCard components. Wrap filtered list in useMemo and
replace && conditional with ternary for rendering safety.
Add fetch-skill-templates.ts script that clones anthropics/skills repo
and generates complete directory trees (scripts, references, assets)
for all 16 skills with base64 encoding for binary files, replacing
the previous single-SKILL.md-only approach. Generated files are
lazy-loaded per skill on user click.
Introduce type definitions separating raw skill data (SkillTemplate)
from UI metadata (SkillTemplateWithMetadata) to match the actual
skill format from upstream repos. Add template card component with
hover state and file count display, template-to-upload conversion
utility, and i18n keys for en-US/zh-Hans.
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.
The toolbar download button now uses the already-fetched download URL
from useQuery (zero extra requests), while tree node downloads keep
using useMutation with React Query-managed isPending state instead of
a hand-rolled useState wrapper.
Introduce a dedicated Zustand ArtifactSlice to manage artifact selection
state with mutual exclusion against the main file tree. Artifact files
from the sandbox can now be opened as tabs in the skill editor, rendered
via a lightweight ArtifactContentPanel that reuses ReadOnlyFilePreview.
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.
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.
Replace useClickAway + fixed positioning in file tree context menu with
a floating-ui based hook that provides collision detection (flip/shift),
ARIA role="menu", Escape/outside-click dismiss, and scroll dismiss via
passive capture listener with ref-stabilized callback.
Replaces window.open with the downloadUrl helper from utils/download.ts
to trigger proper browser download behavior via <a download> instead of
opening a new tab that may display garbled content.
Use shared object reference instead of separate variables to track
upload progress across concurrent Promise.all operations, preventing
progress bar from showing incorrect or regressing values.
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.
Replace simple uploading/success indicator with a full three-state
tooltip (uploading, success, partial_error) that overlays the DropTip
position. Add upload slice to skill editor store and wire progress
tracking into file/folder upload 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.
Refactor the variable inspect panel into a tabbed layout with Variables
and Artifacts tabs. Extract variable logic into VariablesTab, add new
ArtifactsTab with sandbox file tree selection and preview pane, and
improve accessibility across tree nodes and interactive elements.
Use useRef to store saveFile reference and remove it from useEffect
dependencies to prevent cleanup from re-triggering on reference changes.
Also normalize metadata before comparison when clearing dirty state to
ensure filtered tools match correctly.
The sidebar layout was broken when ArtifactsSection expanded - it would
squeeze the FileTree and neither area could scroll. This restructures the
layout so each section has its own scroll container with proper height
constraints.
Remove enabled condition so data is fetched when component mounts,
allowing blue dot to show when files exist even before expanding.
TanStack Query handles request deduplication automatically.
