…tailwind, add Wave AI keybindings to quick tips. update starter layout, integrate wave ai.
WalkthroughIncreases minimum app window size and expands AI panel max width while making the AI panel initially closed. Adds an inputAtom to WaveAIModel and migrates AI panel input handling to that atom; refactors AIPanel and AIPanelInput to use model methods and extracted UI subcomponents (drag overlay, block mask, keycaps, error/welcome messaging). Updates focus utility to accept an optional target. Replaces QuickTips UI (removes its SCSS), adjusts modal padding/class assembly and TOS modal compact behavior, adds CSS variable --color-highlightbg, removes some starter layout blocks, threads meta into tab creation, adds isMacOS() util, and introduces a CLI --magnified flag for editconfig.

4-4: Add missing AI message type imports.
AIMessagePart(used in the new submit flow) andAIMessage(forrealMessageRef) are referenced later in this file but never imported, so the build fails with “Cannot find name …”.

7-13: Consider using semantic<kbd>element.The component renders keyboard shortcuts correctly, but using a
<kbd>element instead of a<div>would be more semantic and provide better accessibility.Apply this diff to use semantic HTML:
-const KeyCap = ({ children }: { children: React.ReactNode }) => { - return ( - <div className="inline-block px-1.5 py-0.5 mx-0.5 font-mono text-[0.85em] text-gray-300 bg-highlightbg rounded-[4px] border border-gray-700 whitespace-nowrap"> - {children} - </div> - ); -}; +const KeyCap = ({ children }: { children: React.ReactNode }) => { + return ( + <kbd className="inline-block px-1.5 py-0.5 mx-0.5 font-mono text-[0.85em] text-gray-300 bg-highlightbg rounded-[4px] border border-gray-700 whitespace-nowrap"> + {children} + </kbd> + ); +};
15-21: Brittle SVG selectors create tight coupling.The complex selectors
[&_svg_#arrow1]:fill-primaryand[&_svg_#arrow2]:fill-primarytarget specific SVG element IDs, creating tight coupling with the SVG structure. If the SVG markup changes (e.g., ID renaming, structure changes), these styles will break silently.Consider one of these approaches:
- Use CSS variables/classes on the SVG itself rather than reaching into its structure from the parent.
- Document the expected SVG structure if this coupling is intentional.
- Use more generic selectors like
[&_svg]:fill-primaryif all SVG paths should have the same color.Example for approach 1:
const IconBox = ({ children }: { children: React.ReactNode }) => { return ( <div className="icon-box bg-highlightbg p-0.5 text-secondary text-xs rounded-[2px] mr-[5px] self-start [&_svg]:relative [&_svg]:top-[3px] [&_svg]:left-[1px] [&_svg]:h-[13px]"> {children} </div> ); };Then apply the fill color directly in the SVG component or via a
fill-primaryclass.frontend/app/modals/tos.tsx (1)
171-185: Consider debouncing the resize handler.The
updateModalHeightfunction mixes declarative React patterns with imperative DOM manipulation. While functional, consider these improvements:
- Debounce the resize handler to prevent excessive re-renders during window resizing
- Use React state for height management instead of direct DOM manipulation via
modalRef.current.style.heightExample debounced resize handler:
import { debounce } from "@/util/util"; // or lodash useEffect(() => { const debouncedUpdate = debounce(updateModalHeight, 150); debouncedUpdate(); window.addEventListener("resize", debouncedUpdate); return () => { window.removeEventListener("resize", debouncedUpdate); }; }, []);frontend/app/aipanel/aipanelinput.tsx (3)
38-38: Extract magic number into a named constant.The max height calculation
6 * 24(144px) is a magic number that represents 6 lines at 24px each. Consider extracting this into a named constant for clarity and maintainability.+const MAX_TEXTAREA_HEIGHT = 6 * 24; // 6 lines at 24px each + export const AIPanelInput = memo(({ onSubmit, status, model }: AIPanelInputProps) => { // ... const resizeTextarea = useCallback(() => { const textarea = textareaRef.current; if (!textarea) return; textarea.style.height = "auto"; const scrollHeight = textarea.scrollHeight; - const maxHeight = 6 * 24; + const maxHeight = MAX_TEXTAREA_HEIGHT; textarea.style.height = `${Math.min(scrollHeight, maxHeight)}px`; }, []);
42-52: Consider adding cleanup for ref registration.The effect registers an input ref with the model but doesn't provide a cleanup function. If the component unmounts or the model instance changes, the model might retain a stale reference. Consider adding cleanup to prevent potential memory leaks.
useEffect(() => { const inputRefObject: React.RefObject<AIPanelInputRef> = { current: { focus: () => { textareaRef.current?.focus(); }, resize: resizeTextarea, }, }; model.registerInputRef(inputRefObject); + + return () => { + // Clear the ref when component unmounts + model.registerInputRef({ current: null }); + }; }, [model, resizeTextarea]);
57-57: Improve type safety by properly typing the event parameter.The cast to
anycircumvents type checking. SinceonSubmitexpects aReact.FormEvent, you can cast more precisely or adjust the event handling.-onSubmit(e as any); +onSubmit(e as unknown as React.FormEvent);

34-34: Highlight background variable looks goodNew token slots cleanly into the theme map and keeps parity with existing hover styling. No issues spotted.
emain/emain-window.ts (1)
29-30: LGTM! Consider verifying on smaller displays.The increased minimum window dimensions (800x500) are reasonable for a modern desktop application and align with the broader UI improvements in this PR. The change will gracefully handle existing windows by enforcing the new minimums at startup.
Consider testing on smaller displays (e.g., 1366x768 or lower) to ensure the app remains comfortably usable at these minimum dimensions and that no critical UI elements are cut off or inaccessible.
frontend/app/element/quicktips.tsx (1)
23-174: LGTM! Clean refactoring with new features.The refactoring successfully:
- Consolidates keybinding rendering with the new
KeyCapcomponent- Restructures the layout using Tailwind flex utilities
- Adds new keybindings for Wave AI panel (Cmd+Shift+a) and focus (Ctrl+Shift+0)
- Removes the external SCSS dependency in favor of inline styles
The logic is preserved and the new structure is more maintainable with consistent component usage.
frontend/app/modals/modal.tsx (2)
5-5: LGTM!The
cnutility import is appropriate for the class composition refactor below.
99-99: Good refactor to Tailwind utilities.The change from template string to
cnutility with explicit padding classes aligns with the move away from SCSS-based styling. Thecnutility properly handles Tailwind class merging and conflicts.frontend/app/modals/tos.tsx (7)
13-13: LGTM!Removing the unused
getApiimport and keeping onlyatomsis correct.
20-20: LGTM!The addition of the
isCompactprop enables responsive layout adjustments based on window height.
44-127: Well-structured responsive layout.The restructuring with flex containers and OverlayScrollbarsComponent provides proper scrollable content handling, and the isCompact-based dynamic spacing creates a good responsive experience.
131-131: LGTM!Consistent with ModalPage1's signature change.
139-164: LGTM!The restructuring follows the same pattern as ModalPage1, maintaining consistency across both pages.
187-202: LGTM!Both useEffect hooks are properly structured with correct cleanup functions to prevent memory leaks.
217-223: LGTM!The dynamic padding classes and modal structure provide good responsive behavior, adjusting padding based on the available window height.
pkg/wcore/workspace.go (2)
211-216: LGTM!The conditional metadata initialization is correct. The initial launch tab receives
"waveai:panelopen": trueto open the AI panel, while other tabs have nil metadata. The boolean value and nil map handling are both valid in Go.
217-217: ApprovecreateTabObjmeta parameter update
The newmetaargument is correctly threaded through the sole call in pkg/wcore/workspace.go, and no other callers were found.frontend/app/aipanel/aipanelinput.tsx (1)
24-172: LGTM! Well-structured refactoring from prop-based to atom-based state management.The component has been successfully refactored to use internal state via
model.inputAtominstead of external props. The new structure with memoization, internal ref registration, and dedicated focus management handlers is clean and maintainable. The file upload validation logic is thorough, and the auto-resize behavior is properly implemented with appropriate effect dependencies.

Fix the type annotation.
The variable pageComp is initialized with null but the type React.JSX.Element doesn't include null. This will cause a TypeScript error.
Apply this diff:
-let pageComp: React.JSX.Element = null;
+let pageComp: React.JSX.Element | null = null;📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In frontend/app/modals/tos.tsx around line 204, the variable pageComp is
declared as React.JSX.Element but initialized to null which is not assignable;
change the type to allow null (e.g., React.JSX.Element | null) or use a
nullable/optional type such as React.ReactNode, then keep the null initializer
or initialize appropriately so the TypeScript error is resolved.

84-164: Consider clarifying the Widget Context toggle location.The welcome message provides excellent onboarding content and correctly uses platform-specific keyboard shortcuts. However, the Widget Context section (lines 105-108) explains the ON/OFF behavior without indicating where users can find or toggle this setting. Consider adding a brief mention of where to locate this control (e.g., "in settings" or "in the panel header") to improve discoverability.

10-11: LGTM! Clean refactor to model-based state management.The shift from prop-based to model.inputAtom-based input management aligns well with the PR's global store architecture. The jotai imports and useAtom usage are correct.
Also applies to: 24-31
42-52: LGTM! Proper ref registration and resize handling.The effect correctly registers the input ref with the model, exposing focus and resize methods. The resize effects have proper dependencies and trigger appropriately on input changes and panel visibility.

28-50: LGTM! Clean component for layout mode overlay.The AIBlockMask component is well-structured, properly memoized, and uses appropriate CSS variables for theming.
52-82: LGTM! Well-designed UI utility components.Both AIDragOverlay and KeyCap are properly implemented with appropriate styling and memoization.
168-188: LGTM! Accessible error message component.The AIErrorMessage component is well-implemented with proper accessibility (aria-label) and overflow handling.
297-304: LGTM! Consistent global store integration.The input management correctly uses the global store via model.inputAtom for reading and writing input state. The focus management through model.focusInput() properly delegates to the model's registered input ref.
Also applies to: 356-361
482-503: LGTM! Clean component-based rendering.The refactor to component-based rendering for overlays, welcome message, and errors improves code organization. The conditional rendering logic correctly shows the welcome message when there are no messages and chat is not loading.

29-51: Consider using a CSS variable for the header height.The hardcoded
44pxinmt-[44px]andh-[calc(100%-44px)]assumes a fixed header height. If the header size changes (e.g., responsive breakpoints), this will break.Consider defining a CSS variable for header height or calculating it dynamically:
+const HEADER_HEIGHT = 44; // or derive from a shared constant + const AIBlockMask = memo(() => { return ( <div ... > <div - className="w-full mt-[44px] h-[calc(100%-44px)] flex items-center justify-center" + className="w-full flex items-center justify-center" + style={{ marginTop: `${HEADER_HEIGHT}px`, height: `calc(100% - ${HEADER_HEIGHT}px)` }} ... >Alternatively, use a CSS variable in your stylesheet:
:root { --ai-panel-header-height: 44px; }And reference it in the component:
- className="w-full mt-[44px] h-[calc(100%-44px)] flex items-center justify-center" + style={{ marginTop: 'var(--ai-panel-header-height)', height: 'calc(100% - var(--ai-panel-header-height))' }}

5-35: LGTM! Clean simplification of the header component.The migration from
useAtomtouseAtomValueis appropriate since the component only reads thewidgetAccessAtom. The removal of model selection UI from the context menu simplifies the header and aligns with the broader refactor toward model-driven state management.frontend/app/aipanel/aipanel.tsx (7)
53-68: LGTM! Well-structured drag overlay component.The
AIDragOverlaycomponent provides clear visual feedback during drag-and-drop operations with appropriate styling and messaging.
70-83: LGTM! Reusable keyboard shortcut component.The
KeyCapcomponent provides a clean, reusable way to display keyboard shortcuts throughout the UI.
85-167: LGTM! Comprehensive and well-structured welcome message.The welcome message provides clear guidance on getting started with Wave AI, including:
- Platform-specific keyboard shortcuts (using
isMacOS()correctly)- Widget context explanation
- File upload capabilities
- Community links with proper security attributes (
rel="noopener")
169-189: LGTM! Clean error message component.The component provides good UX with:
- Clear visual distinction (red color scheme, border)
- Dismissible via close button
- Scrollable content for long error messages
- Proper accessibility with
aria-label
298-303: LGTM! Consistent migration to global input state.The input management has been successfully migrated from local state to the global store via
model.inputAtom. The pattern is consistent across all usage sites:
- Reading input at line 298
- Clearing input after commands at line 303
- Clearing input after message submission at line 357
This aligns with the broader refactor toward atom-based state management described in the AI summary.
Also applies to: 357-357
458-489: LGTM! Well-implemented context menu handler.The context menu provides appropriate options:
- Conditional "Copy" option when text is selected (using
waveAIHasSelection())- "New Chat" action
- "Hide Wave AI" action
Proper event handling with
preventDefault()andstopPropagation()prevents conflicts with parent handlers.
516-540: LGTM! Clean component composition and rendering logic.The rendering logic has been improved with:
- Component extraction for drag overlay and block mask (lines 516-517)
- Clear conditional rendering: welcome message when
messages.length === 0 && !isLoadingChat, otherwise show messages (lines 526-534)- Context menu attached to both rendering paths (lines 527, 531)
- Proper error message display using the new
AIErrorMessagecomponent (lines 535-537)- Consistent use of the
AIPanelInputcomponent (line 539)The refactor improves maintainability while preserving all functionality.
