Inline comments:
In `@src/lib/components/ai/tool-part.svelte`:
- Around line 35-41: The UI branch for tool.state is missing a case for
'input-available', leaving the paragraph empty; update the conditional in
ToolUIPart (the {`#if` tool.state === ...} block in tool-part.svelte) to include
an {:else if tool.state === 'input-available'} branch that renders a fallback
message like "Ready" or "Input received — awaiting execution" so the UI shows a
clear state for 'input-available' instead of blank.
- Around line 35-41: The template conditional for tool.state in tool-part.svelte
only covers 'output-available', 'input-streaming', and 'output-error', leaving
the <p> empty for other states; add an {:else} clause after the existing
branches to render a sensible label for remaining states (e.g., show "Ready" for
'input-available', "Approval requested" for 'approval-requested', "Approval
responded" for 'approval-responded', "Denied" for 'output-denied', or a generic
"Unknown state" fallback) so the <p> always contains text when tool.state is
anything other than the three handled values. Ensure you modify the same {`#if`
tool.state === ...} block that references tool.state to include this {:else}
fallback.
In `@src/lib/components/ui/color-picker/color-picker.svelte`:
- Around line 40-41: The inline style for the color indicator is placed before
the props spread so any style in {...props} can overwrite it; move the style
attribute ("background-color: {value}; color: {textColor};") to after the
{...props} spread and keep the class attribute after the spread as well so
explicit color styling always wins; update the element in the ColorPicker
component (the element using style, {...props}, and class) to place {...props}
first, then style, then class.
- Around line 36-44: Props declares inputClass (and showInput) but inputClass is
never destructured and thus not applied to the trigger Input; update the
ColorPicker component to destructure inputClass (and showInput if needed) out of
restProps where Props are handled, then merge inputClass into the trigger
Input's class list (the cn(...) call inside the {`#snippet` child({ props })}
block) so the trigger uses class={cn('w-auto min-w-26', props.class as string,
inputClass)}; ensure restProps no longer swallows inputClass and that
ColorPicker still forwards the remaining props unchanged.
In `@src/lib/layers/components/CodeLayer.svelte`:
- Around line 20-22: The description claiming "text" yields plain text with no
highlighting is inaccurate because highlightLine() still applies string,
comment, and number regexes even when the keyword list is empty; update the
.describe(...) text in CodeLayer.svelte (the language option description that
mentions "text") to state that "text" disables keyword-based highlighting but
still applies string, comment, and number patterns (so quoted strings, //, #, /*
*/ comments and numeric literals may still be colored), and reference
highlightLine() behavior in the comment if helpful for future maintainers.
In `@src/lib/layers/components/IconLayer.svelte`:
- Around line 155-176: The fill field in IconLayer.svelte currently defaults to
'none' but registers with interpolationFamily: 'continuous', which causes
interpolateContinuous() to throw for non-color keywords; update the registration
for the fill field (the fill z.string().default('none') .register(...)) to
either set interpolationFamily: 'discrete' or change the default to a valid
color (e.g., '#000000') so continuous interpolation only receives valid color
values; ensure you modify the fill registration (not backgroundColor) in the
same block that references fieldRegistry and label 'Fill'.

'input-available' state renders an empty <p> — add a fallback.
The four ToolUIPart states are "input-streaming" | "input-available" | "output-available" | "output-error". The 'input-available' state (input fully received, tool about to execute) has no branch, leaving the paragraph empty.

Vercel AI SDK ToolUIPart state values documentation
💡 Result:
In the Vercel AI SDK (v6), a ToolUIPart is a UI message part named tool-{toolName} whose state comes from the UIToolInvocation union type. The possible state values are: input-streaming, input-available, approval-requested, approval-responded, output-available, output-error, output-denied. In output-available, the optional preliminary: true flag indicates streaming/in-progress output vs a final completed output. [1] [2]

add an {:else} clause after the existing branches to render a sensible label for
remaining states (e.g., show "Ready" for 'input-available', "Approval requested"
for 'approval-requested', "Approval responded" for 'approval-responded',
"Denied" for 'output-denied', or a generic "Unknown state" fallback) so the <p>
always contains text when tool.state is anything other than the three handled
values. Ensure you modify the same {`#if` tool.state === ...} block that
references tool.state to include this {:else} fallback.

inputClass prop is declared in Props but never applied to the trigger Input
inputClass (and showInput) are part of the public Props type but are never destructured, so they fall into restProps and are forwarded to <ColorPicker> (line 57), which ignores them. A caller supplying inputClass to customize the trigger's appearance will silently see no effect. Evidence shows showInput is already being used by callers (e.g., background-picker.svelte line 326), confirming this is a real issue.
If inputClass is intended to style the trigger Input, it should be pulled out of restProps and merged in the cn() call:
♻️ Proposed fix — wire `inputClass` into the trigger
- let { value = $bindable(), optional, onchange, ...restProps }: Props = $props();
+ let { value = $bindable(), optional, onchange, inputClass, showInput: _showInput, ...restProps }: Props = $props();Then in the snippet:

Props declares inputClass (and showInput) but inputClass is never destructured
and thus not applied to the trigger Input; update the ColorPicker component to
destructure inputClass (and showInput if needed) out of restProps where Props
are handled, then merge inputClass into the trigger Input's class list (the
cn(...) call inside the {`#snippet` child({ props })} block) so the trigger uses
class={cn('w-auto min-w-26', props.class as string, inputClass)}; ensure
restProps no longer swallows inputClass and that ColorPicker still forwards the
remaining props unchanged.

style placement before {...props} spread risks overriding the color-indicator styling
In Svelte, when the same attribute appears both explicitly and via a spread, the last one wins. style="background-color: {value}; color: {textColor};" (line 40) is set before {...props} (line 41), so any style key inside props (e.g. from a future Popover.Trigger version adding inline positioning) will silently overwrite the colour-indicator styling. class is already placed correctly after the spread on line 42 — style should follow the same pattern.
🐛 Proposed fix — move `style` after the spread

The inline style for the color indicator is placed before the props spread so
any style in {...props} can overwrite it; move the style attribute
("background-color: {value}; color: {textColor};") to after the {...props}
spread and keep the class attribute after the spread as well so explicit color
styling always wins; update the element in the ColorPicker component (the
element using style, {...props}, and class) to place {...props} first, then
style, then class.

Description for "text" language is misleading.
The description claims "text" provides "plain text with no highlighting," but highlightLine() unconditionally applies string, comment, and number regex patterns to every language — only the keyword list is empty for "text". This means quoted strings, // / # / /* */ patterns, and numeric literals will still be colourised even in "text" mode.
Since these descriptions are specifically intended to guide AI tooling, an inaccurate claim here can cause incorrect behaviour.

fill: 'none' with interpolationFamily: 'continuous' will cause runtime errors during animation.
The fill field defaults to 'none', which is not a valid CSS color that the colord library recognizes. When animating from fill='none' to a hex color, interpolateContinuous() in src/lib/engine/interpolation.ts will throw an error: "continuous interpolation requires numeric or color values" (line 70).
In contrast, backgroundColor='transparent' works fine—'transparent' is a valid CSS color keyword that colord handles correctly.
Change fill to use interpolationFamily: 'discrete' or ensure the default is a valid hex color (e.g., #000000) so continuous interpolation doesn't fail.

🛠️ Refactor suggestion | 🟠 Major
Extract the duplicated options type using z.infer from the existing schema
The inline literal union 'closest-side' | 'closest-corner' | 'farthest-side' | 'farthest-corner' is repeated verbatim in all three changed signatures (lines 144, 176, 198). The identical four values are already the source of truth in RadialGradientSchema.size (line 71). This should be derived once via z.infer and shared.
♻️ Proposed fix — extract a shared type from the schema
Add a named type in the Types section (after line 123):
export type GradientBackground = LinearGradient | RadialGradient | ConicGradient;
export type BackgroundValue = SolidBackground | GradientBackground;
+
+/** Render-time overrides for background CSS generation */
+export type BackgroundRenderOptions = {
+ radialSize?: z.infer<typeof RadialGradientSchema>['size'];
+};Then replace all three inline option types with the new alias:
-export function backgroundValueToCSS(
- value: BackgroundValue,
- options?: { radialSize?: 'closest-side' | 'closest-corner' | 'farthest-side' | 'farthest-corner' }
-): string {
