Walkthrough

Adds a large set of new UI components and utilities to the renderer, introduces a CSS-variable based theme (light/dark/system) and a useTheme hook, replaces hard-coded color tokens with semantic tokens across core renderer components, adds a cn utility and components.json, adjusts deps/config and a small smoke-test script tweak.

Changes

Cohort / File(s)	Summary
UI component library apps/renderer/src/components/ui/*	Adds 30+ new UI modules (accordion, alert, autocomplete, avatar, badge, button, card, checkbox, collapsible, combobox, command, dialog, empty, field, fieldset, form, input-group, input, kbd, label, menu, popover, progress, radio-group, scroll-area, select, separator, sheet, skeleton, spinner, switch, table, tabs, textarea, toast). Each wraps @base-ui/react primitives, applies data-slot attributes, CVA variants and composed Tailwind classes. Review API shapes, typings, and consistent class/slot usage.
Core renderer components apps/renderer/src/App.tsx, apps/renderer/src/components/ChatView.tsx, apps/renderer/src/components/ChatMarkdown.tsx, apps/renderer/src/components/DiffPanel.tsx, apps/renderer/src/components/Sidebar.tsx	Replaces hex color classes with semantic tokens; ChatView integrates new InputGroup, Select, Button components and removes previous textarea auto-resize logic; ChatMarkdown and DiffPanel styling tokens updated; Sidebar adds theme toggle and theme-aware styling. Validate behavioral changes where logic was removed (e.g., textarea resizing, model menu handling).
Theming & CSS apps/renderer/src/index.css, apps/renderer/src/hooks/useTheme.ts	Introduces CSS variable theme system with light/dark variants and a .no-transitions helper; adds many CSS token definitions and dark overrides. Adds useTheme hook (light
Utilities & small libs apps/renderer/src/lib/utils.ts, apps/renderer/components.json	Adds cn(...inputs) util combining clsx + twMerge. Adds components.json with UI framework config, aliases, Tailwind/tokens and registries. Confirm imports use the new alias and utility.
Config & build apps/renderer/tsconfig.json, apps/renderer/vite.config.ts, biome.json	Adds #/* path alias and resolves # in Vite; sets exactOptionalPropertyTypes: false in tsconfig; relaxes biome a11y rule noSvgWithoutTitle.
Dependencies apps/renderer/package.json	Adds runtime deps including @base-ui/react, class-variance-authority, clsx, lucide-react, tailwind-merge and reorders react-markdown. Verify lockfile and install.
Markup & scripts apps/renderer/index.html, apps/desktop/scripts/smoke-test.mjs	Removes body Tailwind class in index.html. Small smoke-test script tweak: reorder imports from node:child_process and use template literal for error output. Minor script change.

🧹 Recent nitpick comments

apps/renderer/src/components/ChatView.tsx (1)

312-344: Consider using cn utility for conditional class handling.

The deeply nested ternaries for status indicator styling reduce readability. Using the cn utility with object syntax would make the phase-based styling clearer and more maintainable.

♻️ Suggested refactor using cn utility

+const statusContainerClasses: Record<string, string> = {+ running: "border-sky-400/35 bg-sky-500/8 text-sky-700 dark:text-sky-100",+ connecting: "border-amber-400/35 bg-amber-500/8 text-amber-700 dark:text-amber-100",+ ready: "border-emerald-400/35 bg-emerald-500/8 text-emerald-700 dark:text-emerald-100",+ disconnected: "border-border bg-secondary text-muted-foreground",+};++const statusDotClasses: Record<string, string> = {+ running: "bg-sky-200",+ connecting: "bg-amber-200",+ ready: "bg-emerald-200",+ disconnected: "bg-muted-foreground/40",+};

Then use:

<divclassName={cn("inline-flex items-center gap-2 rounded-full border px-2.5 py-1 text-[10px]",statusContainerClasses[phase]??statusContainerClasses.disconnected)}>

Based on learnings: "Use Tailwind CSS for styling - no inline styles, use cn for conditional classes".

apps/renderer/src/components/Sidebar.tsx (1)

138-152: Prefer Coss UI for the new icon-only theme toggle.

To keep styling and interaction patterns consistent with the rest of the app, consider swapping this raw <button> for the equivalent Coss UI icon/button primitive.

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling.

Add light/dark/system theme cycling and apply token-based theming across Sidebar, ChatView, and global styles to introduce light mode

Introduce a useTheme hook with localStorage persistence and a Sidebar header button to cycle system/light/dark; switch global and app styling to CSS variables and semantic Tailwind tokens; refactor ChatView and Sidebar UI to use shared UI primitives; remove thread status badges, editor/approval flows, and keyboard shortcuts; update model selection in new project flow.

📍Where to Start

Start with the useTheme hook in useTheme.ts and its integration in the Sidebar in Sidebar.tsx, then review theme token application in index.css.

In `@apps/renderer/src/components/Sidebar.tsx`:
- Around line 225-230: The button currently uses the disabled prop which
conflicts with accessibility guidance and tooltips; instead remove the disabled
attribute on the button element, add aria-disabled={isPickingFolder} to reflect
state, keep/adjust the visual "disabled" classes conditionally when
isPickingFolder, and add a click guard at the top of handlePickFolder (or inline
in the onClick wrapper) that returns early if isPickingFolder so clicks are
ignored; ensure tooltip behavior is preserved by using aria-disabled rather than
disabled.
In `@apps/renderer/src/components/ui/combobox.tsx`:
- Around line 196-214: The SVG in the Combobox component uses an incorrect xmlns
value; update the xmlns on the SVG inside ComboboxPrimitive.ItemIndicator to the
correct "http://www.w3.org/2000/svg" string so the icon renders properly (look
for the SVG element in the ComboboxPrimitive.ItemIndicator within the
combobox.tsx component and change the xmlns attribute value).
In `@apps/renderer/src/components/ui/empty.tsx`:
- Around line 94-105: The component EmptyDescription is typed as
React.ComponentProps<"p"> but renders a <div>, causing a props/semantic
mismatch; fix it by making the types and markup consistent—either change the
rendered element to <p> (keep the same props type) or change the prop type to
React.ComponentProps<"div"> (keep the <div>); update the function signature
(EmptyDescription) accordingly and ensure spreading {...props}, className and
data-slot="empty-description" remain correct for the chosen element.
In `@apps/renderer/src/components/ui/scroll-area.tsx`:
- Around line 5-35: Replace the custom use of ScrollAreaPrimitive
(ScrollAreaPrimitive.Root, ScrollAreaPrimitive.Viewport,
ScrollAreaPrimitive.Corner) and the local ScrollBar components with the Coss UI
ScrollArea wrapper: install the package via the shadcn CLI (`pnpm dlx
shadcn@latest add `@coss/scroll-area``), import Coss's ScrollArea,
ScrollAreaViewport and Corner (or the exported equivalents) and re-create this
component as a thin wrapper named ScrollArea that forwards props and children
while preserving the scrollFade and scrollbarGutter booleans by mapping them to
equivalent className masks and gutter classes on the Coss component (apply the
same mask expressions and `data-has-overflow-*` gutter classes), and ensure
data-slot attributes (scroll-area-viewport, scroll-area-corner) remain on the
mapped children so existing consumers continue to work.
In `@apps/renderer/src/components/ui/select.tsx`:
- Around line 128-142: The SVG used inside SelectPrimitive.ItemIndicator has a
typo in its xmlns attribute; update the xmlns on the SVG element within
SelectPrimitive.ItemIndicator to the correct namespace
"http://www.w3.org/2000/svg" so the checkmark renders correctly across browsers
(locate the SVG in the SelectPrimitive.ItemIndicator block and replace the
incorrect "http://www.w3.org/1500/svg" value).
In `@apps/renderer/src/components/ui/skeleton.tsx`:
- Around line 1-3: The file uses React.ComponentProps<"div"> in the Skeleton
component but doesn't import the React namespace; add an import for React (e.g.,
add "import React from 'react'" or "import type React from 'react'") at the top
of apps/renderer/src/components/ui/skeleton.tsx so the React.ComponentProps type
resolves for the Skeleton function signature.

🧹 Nitpick comments (6)

apps/renderer/src/components/ui/table.tsx (1)

36-47: Consider extracting long class strings for maintainability.

The class string on line 40 is quite long with many frame-conditional styles. While this is a common pattern in shadcn-style UI libraries, consider extracting the frame-specific styles into a separate variable or using Tailwind's @apply directive in a CSS file for better readability.

That said, this is a stylistic preference and the current implementation is functionally correct.

apps/renderer/src/components/ui/separator.tsx (1)

13-13: The CSS selector for vertical self-stretch is fragile and likely won't work as intended.

The selector not-[[class^='h-']]:not-[[class*='_h-']] checks whether the class attribute string starts with 'h-' or contains '_h-'. Since other classes (e.g., shrink-0) will appear first in the composed className, the [class^='h-'] condition will almost never match—even when a height utility like h-10 is present.

Consider simplifying by always applying self-stretch for vertical orientation and letting explicit height classes override it naturally, or document that consumers should use inline styles / CSS variables for custom heights:

♻️ Suggested simplification

- "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:w-px data-[orientation=vertical]:not-[[class^='h-']]:not-[[class*='_h-']]:self-stretch",+ "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:h-full data-[orientation=vertical]:w-px",

apps/renderer/src/components/ui/toast.tsx (1)

220-250: Consider extracting shared toast content into a reusable component.

The toast content rendering here (icon, title, description, action button) is nearly identical to lines 128-158 in the Toasts component. Extracting this into a shared ToastContent component would reduce duplication and ensure consistency when making future changes.

♻️ Suggested extraction

// Shared component to use in both Toasts and AnchoredToastsfunctionToastContentBody({ toast }: {toast: Toast.ToastObject}){constIcon=toast.type
? TOAST_ICONS[toast.typeaskeyoftypeofTOAST_ICONS]
: null;return(<Toast.ContentclassName="pointer-events-auto flex items-center justify-between gap-1.5 overflow-hidden px-3.5 py-3 text-sm ..."><divclassName="flex gap-2">{Icon&&(<divclassName="[&>svg]:h-lh [&>svg]:w-4 [&_svg]:pointer-events-none [&_svg]:shrink-0"data-slot="toast-icon"><IconclassName="in-data-[type=loading]:animate-spin ..."/></div>)}<divclassName="flex flex-col gap-0.5"><Toast.TitleclassName="font-medium"data-slot="toast-title"/><Toast.DescriptionclassName="text-muted-foreground"data-slot="toast-description"/></div></div>{toast.actionProps&&(<Toast.ActionclassName={buttonVariants({size: "xs"})}data-slot="toast-action">{toast.actionProps.children}</Toast.Action>)}</Toast.Content>);}

apps/renderer/src/components/ui/kbd.tsx (1)

5-26: Prefer Coss UI primitives for consistency.

These custom Kbd/KbdGroup wrappers diverge from the guideline to use Coss UI components (installed via the ShadCN CLI) for consistent styling and Base UI accessibility alignment. If a Coss kbd component exists, consider swapping to it (or document why bespoke wrappers are required).

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling. Install new components using the ShadCN CLI (e.g., bunx --bun shadcnlatest add coss/button). Refer to Base UI docs for accessibility guidelines on primitives.

apps/renderer/src/components/ui/textarea.tsx (1)

7-10: Consider documenting or removing the number type for size.

The size prop accepts "sm" | "default" | "lg" | number, but the internal styling logic (lines 35-38) only handles the string literals. When a number is passed, it's set on data-size but no corresponding styles are applied.

If numeric sizes are intended for custom CSS handling via data-size, consider adding a brief comment documenting this. Otherwise, consider restricting the type to the supported string literals only.

apps/renderer/src/index.css (1)

227-242: Consider using CSS variables for scrollbar colors for consistency.

The scrollbar styling uses hardcoded rgba() values while the rest of the file uses CSS variables. For better theme consistency, consider using the defined tokens:

♻️ Optional: Use CSS variables for scrollbar colors

 ::-webkit-scrollbar-thumb {
- background: rgba(0, 0, 0, 0.15);+ background: var(--muted-foreground);+ opacity: 0.15;
border-radius: 3px;
}
::-webkit-scrollbar-thumb:hover {
- background: rgba(0, 0, 0, 0.25);+ background: var(--muted-foreground);+ opacity: 0.25;
}
.dark ::-webkit-scrollbar-thumb {
- background: rgba(255, 255, 255, 0.1);+ background: var(--muted-foreground);+ opacity: 0.1;
}
.dark ::-webkit-scrollbar-thumb:hover {
- background: rgba(255, 255, 255, 0.18);+ background: var(--muted-foreground);+ opacity: 0.18;
}

Note: Opacity on scrollbar thumbs may have limited browser support; the current approach works reliably.

⚠️ Potential issue | 🟡 Minor

Avoid the disabled prop; use aria-disabled and a click guard instead.

The current disabled usage conflicts with the repo’s accessibility guidance and can break tooltips. Use styling plus a guard in the handler.

🛠️ Suggested fix

"cursor-not-allowed opacity-60" : ""+ }`}+ aria-disabled={isPickingFolder}+ onClick={() => {+ if (isPickingFolder) return;+ void handlePickFolder();+ }}

Replace with Coss UI ScrollArea component for consistency with codebase guidelines.

Coss UI provides a ScrollArea component that should be installed via ShadCN CLI: pnpm dlx shadcn@latest add @coss/scroll-area``. The custom extensions (scrollFade, `scrollbarGutter`) can be preserved by wrapping the Coss UI component instead of using Base UI directly.

Add React type import for ComponentProps reference.

Line 3 references React.ComponentProps<"div"> without importing the React namespace. While the modern JSX transform (jsx: "react-jsx") eliminates the need for React in JSX elements, explicit namespace references like React.ComponentProps still require the import and will cause a type-checking error.

+import type * as React from "react";
import { cn } from "#/lib/utils";

451-456: Minor: Redundant dark: prefixes for transparent and semantic tokens.

bg-transparent is identical in both modes, and bg-accent is a semantic token that already adapts to the theme. The dark: prefixes are unnecessary here.

⚠️ Potential issue | 🟡 Minor

Capitalization of "xhigh" produces awkward "Xhigh" in the UI.

The inline capitalization effort.charAt(0).toUpperCase() + effort.slice(1) transforms "xhigh" to "Xhigh", which isn't user-friendly. Consider a display name mapping for better readability.

Walkthrough

Adds a large set of new UI components and utilities to the renderer, introduces a CSS-variable based theme (light/dark/system) and a useTheme hook, replaces hard-coded color tokens with semantic tokens across core renderer components, adds a cn utility and components.json, adjusts deps/config and a small smoke-test script tweak.

Changes

Cohort / File(s)	Summary
UI component library apps/renderer/src/components/ui/*	Adds 30+ new UI modules (accordion, alert, autocomplete, avatar, badge, button, card, checkbox, collapsible, combobox, command, dialog, empty, field, fieldset, form, input-group, input, kbd, label, menu, popover, progress, radio-group, scroll-area, select, separator, sheet, skeleton, spinner, switch, table, tabs, textarea, toast). Each wraps @base-ui/react primitives, applies data-slot attributes, CVA variants and composed Tailwind classes. Review API shapes, typings, and consistent class/slot usage.
Core renderer components apps/renderer/src/App.tsx, apps/renderer/src/components/ChatView.tsx, apps/renderer/src/components/ChatMarkdown.tsx, apps/renderer/src/components/DiffPanel.tsx, apps/renderer/src/components/Sidebar.tsx	Replaces hex color classes with semantic tokens; ChatView integrates new InputGroup, Select, Button components and removes previous textarea auto-resize logic; ChatMarkdown and DiffPanel styling tokens updated; Sidebar adds theme toggle and theme-aware styling. Validate behavioral changes where logic was removed (e.g., textarea resizing, model menu handling).
Theming & CSS apps/renderer/src/index.css, apps/renderer/src/hooks/useTheme.ts	Introduces CSS variable theme system with light/dark variants and a .no-transitions helper; adds many CSS token definitions and dark overrides. Adds useTheme hook (light
Utilities & small libs apps/renderer/src/lib/utils.ts, apps/renderer/components.json	Adds cn(...inputs) util combining clsx + twMerge. Adds components.json with UI framework config, aliases, Tailwind/tokens and registries. Confirm imports use the new alias and utility.
Config & build apps/renderer/tsconfig.json, apps/renderer/vite.config.ts, biome.json	Adds #/* path alias and resolves # in Vite; sets exactOptionalPropertyTypes: false in tsconfig; relaxes biome a11y rule noSvgWithoutTitle.

apps/renderer/src/components/ChatView.tsx (1)

312-344: Consider using cn utility for conditional class handling.

The deeply nested ternaries for status indicator styling reduce readability. Using the cn utility with object syntax would make the phase-based styling clearer and more maintainable.

♻️ Suggested refactor using cn utility

+const statusContainerClasses: Record<string, string> = {+ running: "border-sky-400/35 bg-sky-500/8 text-sky-700 dark:text-sky-100",+ connecting: "border-amber-400/35 bg-amber-500/8 text-amber-700 dark:text-amber-100",+ ready: "border-emerald-400/35 bg-emerald-500/8 text-emerald-700 dark:text-emerald-100",+ disconnected: "border-border bg-secondary text-muted-foreground",+};++const statusDotClasses: Record<string, string> = {+ running: "bg-sky-200",+ connecting: "bg-amber-200",+ ready: "bg-emerald-200",+ disconnected: "bg-muted-foreground/40",+};

Then use:

<divclassName={cn("inline-flex items-center gap-2 rounded-full border px-2.5 py-1 text-[10px]",statusContainerClasses[phase]??statusContainerClasses.disconnected)}>

Based on learnings: "Use Tailwind CSS for styling - no inline styles, use cn for conditional classes".

Add light/dark/system theme cycling and apply token-based theming across Sidebar, ChatView, and global styles to introduce light mode

Introduce a useTheme hook with localStorage persistence and a Sidebar header button to cycle system/light/dark; switch global and app styling to CSS variables and semantic Tailwind tokens; refactor ChatView and Sidebar UI to use shared UI primitives; remove thread status badges, editor/approval flows, and keyboard shortcuts; update model selection in new project flow.

📍Where to Start

Start with the useTheme hook in useTheme.ts and its integration in the Sidebar in Sidebar.tsx, then review theme token application in index.css.

ScrollAreaPrimitive.Corner) and the local ScrollBar components with the Coss UI
ScrollArea wrapper: install the package via the shadcn CLI (`pnpm dlx
shadcn@latest add `@coss/scroll-area``), import Coss's ScrollArea,
ScrollAreaViewport and Corner (or the exported equivalents) and re-create this
component as a thin wrapper named ScrollArea that forwards props and children
while preserving the scrollFade and scrollbarGutter booleans by mapping them to
equivalent className masks and gutter classes on the Coss component (apply the
same mask expressions and `data-has-overflow-*` gutter classes), and ensure
data-slot attributes (scroll-area-viewport, scroll-area-corner) remain on the
mapped children so existing consumers continue to work.
In `@apps/renderer/src/components/ui/select.tsx`:
- Around line 128-142: The SVG used inside SelectPrimitive.ItemIndicator has a
typo in its xmlns attribute; update the xmlns on the SVG element within
SelectPrimitive.ItemIndicator to the correct namespace
"http://www.w3.org/2000/svg" so the checkmark renders correctly across browsers
(locate the SVG in the SelectPrimitive.ItemIndicator block and replace the

🧹 Nitpick comments (6)

apps/renderer/src/components/ui/table.tsx (1)

36-47: Consider extracting long class strings for maintainability.

The class string on line 40 is quite long with many frame-conditional styles. While this is a common pattern in shadcn-style UI libraries, consider extracting the frame-specific styles into a separate variable or using Tailwind's @apply directive in a CSS file for better readability.

That said, this is a stylistic preference and the current implementation is functionally correct.

apps/renderer/src/components/ui/separator.tsx (1)

13-13: The CSS selector for vertical self-stretch is fragile and likely won't work as intended.

The selector not-[[class^='h-']]:not-[[class*='_h-']] checks whether the class attribute string starts with 'h-' or contains '_h-'. Since other classes (e.g., shrink-0) will appear first in the composed className, the [class^='h-'] condition will almost never match—even when a height utility like h-10 is present.

Consider simplifying by always applying self-stretch for vertical orientation and letting explicit height classes override it naturally, or document that consumers should use inline styles / CSS variables for custom heights:

♻️ Suggested simplification

- "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:w-px data-[orientation=vertical]:not-[[class^='h-']]:not-[[class*='_h-']]:self-stretch",+ "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:h-full data-[orientation=vertical]:w-px",

apps/renderer/src/components/ui/toast.tsx (1)

220-250: Consider extracting shared toast content into a reusable component.

The toast content rendering here (icon, title, description, action button) is nearly identical to lines 128-158 in the Toasts component. Extracting this into a shared ToastContent component would reduce duplication and ensure consistency when making future changes.

♻️ Suggested extraction

// Shared component to use in both Toasts and AnchoredToastsfunctionToastContentBody({ toast }: {toast: Toast.ToastObject}){constIcon=toast.type
? TOAST_ICONS[toast.typeaskeyoftypeofTOAST_ICONS]
: null;return(<Toast.ContentclassName="pointer-events-auto flex items-center justify-between gap-1.5 overflow-hidden px-3.5 py-3 text-sm ..."><divclassName="flex gap-2">{Icon&&(<divclassName="[&>svg]:h-lh [&>svg]:w-4 [&_svg]:pointer-events-none [&_svg]:shrink-0"data-slot="toast-icon"><IconclassName="in-data-[type=loading]:animate-spin ..."/></div>)}<divclassName="flex flex-col gap-0.5"><Toast.TitleclassName="font-medium"data-slot="toast-title"/><Toast.DescriptionclassName="text-muted-foreground"data-slot="toast-description"/></div></div>{toast.actionProps&&(<Toast.ActionclassName={buttonVariants({size: "xs"})}data-slot="toast-action">{toast.actionProps.children}</Toast.Action>)}</Toast.Content>);}

apps/renderer/src/components/ui/kbd.tsx (1)

5-26: Prefer Coss UI primitives for consistency.

These custom Kbd/KbdGroup wrappers diverge from the guideline to use Coss UI components (installed via the ShadCN CLI) for consistent styling and Base UI accessibility alignment. If a Coss kbd component exists, consider swapping to it (or document why bespoke wrappers are required).

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling. Install new components using the ShadCN CLI (e.g., bunx --bun shadcnlatest add coss/button). Refer to Base UI docs for accessibility guidelines on primitives.

apps/renderer/src/components/ui/textarea.tsx (1)

7-10: Consider documenting or removing the number type for size.

The size prop accepts "sm" | "default" | "lg" | number, but the internal styling logic (lines 35-38) only handles the string literals. When a number is passed, it's set on data-size but no corresponding styles are applied.

If numeric sizes are intended for custom CSS handling via data-size, consider adding a brief comment documenting this. Otherwise, consider restricting the type to the supported string literals only.

apps/renderer/src/index.css (1)

227-242: Consider using CSS variables for scrollbar colors for consistency.

The scrollbar styling uses hardcoded rgba() values while the rest of the file uses CSS variables. For better theme consistency, consider using the defined tokens:

♻️ Optional: Use CSS variables for scrollbar colors

 ::-webkit-scrollbar-thumb {
- background: rgba(0, 0, 0, 0.15);+ background: var(--muted-foreground);+ opacity: 0.15;
border-radius: 3px;
}
::-webkit-scrollbar-thumb:hover {
- background: rgba(0, 0, 0, 0.25);+ background: var(--muted-foreground);+ opacity: 0.25;
}
.dark ::-webkit-scrollbar-thumb {
- background: rgba(255, 255, 255, 0.1);+ background: var(--muted-foreground);+ opacity: 0.1;
}
.dark ::-webkit-scrollbar-thumb:hover {
- background: rgba(255, 255, 255, 0.18);+ background: var(--muted-foreground);+ opacity: 0.18;
}

Note: Opacity on scrollbar thumbs may have limited browser support; the current approach works reliably.

Replace with Coss UI ScrollArea component for consistency with codebase guidelines.

Coss UI provides a ScrollArea component that should be installed via ShadCN CLI: pnpm dlx shadcn@latest add @coss/scroll-area``. The custom extensions (scrollFade, `scrollbarGutter`) can be preserved by wrapping the Coss UI component instead of using Base UI directly. This ensures alignment with the team's component catalog and styling standards.

Coss's ScrollArea, ScrollAreaViewport and Corner (or the exported equivalents)
and re-create this component as a thin wrapper named ScrollArea that forwards
props and children while preserving the scrollFade and scrollbarGutter booleans
by mapping them to equivalent className masks and gutter classes on the Coss
component (apply the same mask expressions and `data-has-overflow-*` gutter

scroll-area-corner) remain on the mapped children so existing consumers continue

Add React type import for ComponentProps reference.

Line 3 references React.ComponentProps<"div"> without importing the React namespace. While the modern JSX transform (jsx: "react-jsx") eliminates the need for React in JSX elements, explicit namespace references like React.ComponentProps still require the import and will cause a type-checking error.

apps/renderer/src/components/ChatView.tsx (1)

312-344: Consider using cn utility for conditional class handling.

The deeply nested ternaries for status indicator styling reduce readability. Using the cn utility with object syntax would make the phase-based styling clearer and more maintainable.

♻️ Suggested refactor using cn utility

+const statusContainerClasses: Record<string, string> = {+ running: "border-sky-400/35 bg-sky-500/8 text-sky-700 dark:text-sky-100",+ connecting: "border-amber-400/35 bg-amber-500/8 text-amber-700 dark:text-amber-100",+ ready: "border-emerald-400/35 bg-emerald-500/8 text-emerald-700 dark:text-emerald-100",+ disconnected: "border-border bg-secondary text-muted-foreground",+};++const statusDotClasses: Record<string, string> = {+ running: "bg-sky-200",+ connecting: "bg-amber-200",+ ready: "bg-emerald-200",+ disconnected: "bg-muted-foreground/40",+};

Then use:

<divclassName={cn("inline-flex items-center gap-2 rounded-full border px-2.5 py-1 text-[10px]",statusContainerClasses[phase]??statusContainerClasses.disconnected)}>

Based on learnings: "Use Tailwind CSS for styling - no inline styles, use cn for conditional classes".

Add light/dark/system theme cycling and apply token-based theming across Sidebar, ChatView, and global styles to introduce light mode

Introduce a useTheme hook with localStorage persistence and a Sidebar header button to cycle system/light/dark; switch global and app styling to CSS variables and semantic Tailwind tokens; refactor ChatView and Sidebar UI to use shared UI primitives; remove thread status badges, editor/approval flows, and keyboard shortcuts; update model selection in new project flow.

📍Where to Start

Start with the useTheme hook in useTheme.ts and its integration in the Sidebar in Sidebar.tsx, then review theme token application in index.css.

🧹 Nitpick comments (6)

apps/renderer/src/components/ui/table.tsx (1)

36-47: Consider extracting long class strings for maintainability.

The class string on line 40 is quite long with many frame-conditional styles. While this is a common pattern in shadcn-style UI libraries, consider extracting the frame-specific styles into a separate variable or using Tailwind's @apply directive in a CSS file for better readability.

That said, this is a stylistic preference and the current implementation is functionally correct.

apps/renderer/src/components/ui/separator.tsx (1)

13-13: The CSS selector for vertical self-stretch is fragile and likely won't work as intended.

The selector not-[[class^='h-']]:not-[[class*='_h-']] checks whether the class attribute string starts with 'h-' or contains '_h-'. Since other classes (e.g., shrink-0) will appear first in the composed className, the [class^='h-'] condition will almost never match—even when a height utility like h-10 is present.

Consider simplifying by always applying self-stretch for vertical orientation and letting explicit height classes override it naturally, or document that consumers should use inline styles / CSS variables for custom heights:

♻️ Suggested simplification

- "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:w-px data-[orientation=vertical]:not-[[class^='h-']]:not-[[class*='_h-']]:self-stretch",+ "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:h-full data-[orientation=vertical]:w-px",

apps/renderer/src/components/ui/toast.tsx (1)

220-250: Consider extracting shared toast content into a reusable component.

The toast content rendering here (icon, title, description, action button) is nearly identical to lines 128-158 in the Toasts component. Extracting this into a shared ToastContent component would reduce duplication and ensure consistency when making future changes.

♻️ Suggested extraction

// Shared component to use in both Toasts and AnchoredToastsfunctionToastContentBody({ toast }: {toast: Toast.ToastObject}){constIcon=toast.type
? TOAST_ICONS[toast.typeaskeyoftypeofTOAST_ICONS]

apps/renderer/src/components/ui/kbd.tsx (1)

5-26: Prefer Coss UI primitives for consistency.

These custom Kbd/KbdGroup wrappers diverge from the guideline to use Coss UI components (installed via the ShadCN CLI) for consistent styling and Base UI accessibility alignment. If a Coss kbd component exists, consider swapping to it (or document why bespoke wrappers are required).

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling. Install new components using the ShadCN CLI (e.g., bunx --bun shadcnlatest add coss/button). Refer to Base UI docs for accessibility guidelines on primitives.

apps/renderer/src/components/ui/textarea.tsx (1)

7-10: Consider documenting or removing the number type for size.

The size prop accepts "sm" | "default" | "lg" | number, but the internal styling logic (lines 35-38) only handles the string literals. When a number is passed, it's set on data-size but no corresponding styles are applied.

If numeric sizes are intended for custom CSS handling via data-size, consider adding a brief comment documenting this. Otherwise, consider restricting the type to the supported string literals only.

apps/renderer/src/index.css (1)

227-242: Consider using CSS variables for scrollbar colors for consistency.

The scrollbar styling uses hardcoded rgba() values while the rest of the file uses CSS variables. For better theme consistency, consider using the defined tokens:

♻️ Optional: Use CSS variables for scrollbar colors

 ::-webkit-scrollbar-thumb {
- background: rgba(0, 0, 0, 0.15);+ background: var(--muted-foreground);+ opacity: 0.15;
border-radius: 3px;
}
::-webkit-scrollbar-thumb:hover {
- background: rgba(0, 0, 0, 0.25);+ background: var(--muted-foreground);+ opacity: 0.25;
}
.dark ::-webkit-scrollbar-thumb {
- background: rgba(255, 255, 255, 0.1);+ background: var(--muted-foreground);+ opacity: 0.1;
}
.dark ::-webkit-scrollbar-thumb:hover {
- background: rgba(255, 255, 255, 0.18);+ background: var(--muted-foreground);+ opacity: 0.18;
}

Note: Opacity on scrollbar thumbs may have limited browser support; the current approach works reliably.

Type mismatch: Component typed as <p> but renders <div>.

EmptyDescription accepts React.ComponentProps<"p"> but renders a <div>. This inconsistency could confuse consumers and allows <p>-specific props that won't apply to the rendered <div>.

💡 Proposed fix

Either change the rendered element to match the type:

-function EmptyDescription({ className, ...props }: React.ComponentProps<"p">) {+function EmptyDescription({ className, ...props }: React.ComponentProps<"div">) {
return (

Or render a <p> to match the type (if semantically appropriate):

 function EmptyDescription({ className, ...props }: React.ComponentProps<"p">) {

Replace with Coss UI ScrollArea component for consistency with codebase guidelines.

Coss UI provides a ScrollArea component that should be installed via ShadCN CLI: pnpm dlx shadcn@latest add @coss/scroll-area``. The custom extensions (scrollFade, `scrollbarGutter`) can be preserved by wrapping the Coss UI component instead of using Base UI directly. This ensures alignment with the team's component catalog and styling standards.

Add React type import for ComponentProps reference.

While the modern JSX transform (jsx: "react-jsx") eliminates the need for React in JSX elements, explicit namespace references like React.ComponentProps still require the import and will cause a type-checking error.

Walkthrough

Adds a large set of new UI components and utilities to the renderer, introduces a CSS-variable based theme (light/dark/system) and a useTheme hook, replaces hard-coded color tokens with semantic tokens across core renderer components, adds a cn utility and components.json, adjusts deps/config and a small smoke-test script tweak.

Changes

Cohort / File(s)	Summary
UI component library apps/renderer/src/components/ui/*	Adds 30+ new UI modules (accordion, alert, autocomplete, avatar, badge, button, card, checkbox, collapsible, combobox, command, dialog, empty, field, fieldset, form, input-group, input, kbd, label, menu, popover, progress, radio-group, scroll-area, select, separator, sheet, skeleton, spinner, switch, table, tabs, textarea, toast). Each wraps @base-ui/react primitives, applies data-slot attributes, CVA variants and composed Tailwind classes. Review API shapes, typings, and consistent class/slot usage.
Core renderer components apps/renderer/src/App.tsx, apps/renderer/src/components/ChatView.tsx, apps/renderer/src/components/ChatMarkdown.tsx, apps/renderer/src/components/DiffPanel.tsx, apps/renderer/src/components/Sidebar.tsx	Replaces hex color classes with semantic tokens; ChatView integrates new InputGroup, Select, Button components and removes previous textarea auto-resize logic; ChatMarkdown and DiffPanel styling tokens updated; Sidebar adds theme toggle and theme-aware styling. Validate behavioral changes where logic was removed (e.g., textarea resizing, model menu handling).
Theming & CSS apps/renderer/src/index.css, apps/renderer/src/hooks/useTheme.ts	Introduces CSS variable theme system with light/dark variants and a .no-transitions helper; adds many CSS token definitions and dark overrides. Adds useTheme hook (light
Utilities & small libs apps/renderer/src/lib/utils.ts, apps/renderer/components.json	Adds cn(...inputs) util combining clsx + twMerge. Adds components.json with UI framework config, aliases, Tailwind/tokens and registries. Confirm imports use the new alias and utility.
Config & build apps/renderer/tsconfig.json, apps/renderer/vite.config.ts, biome.json	Adds #/* path alias and resolves # in Vite; sets exactOptionalPropertyTypes: false in tsconfig; relaxes biome a11y rule noSvgWithoutTitle.
Dependencies apps/renderer/package.json	Adds runtime deps including @base-ui/react, class-variance-authority, clsx, lucide-react, tailwind-merge and reorders react-markdown. Verify lockfile and install.
Markup & scripts apps/renderer/index.html, apps/desktop/scripts/smoke-test.mjs	Removes body Tailwind class in index.html. Small smoke-test script tweak: reorder imports from node:child_process and use template literal for error output. Minor script change.

apps/renderer/src/components/ChatView.tsx (1)

312-344: Consider using cn utility for conditional class handling.

The deeply nested ternaries for status indicator styling reduce readability. Using the cn utility with object syntax would make the phase-based styling clearer and more maintainable.

♻️ Suggested refactor using cn utility

+const statusContainerClasses: Record<string, string> = {+ running: "border-sky-400/35 bg-sky-500/8 text-sky-700 dark:text-sky-100",+ connecting: "border-amber-400/35 bg-amber-500/8 text-amber-700 dark:text-amber-100",+ ready: "border-emerald-400/35 bg-emerald-500/8 text-emerald-700 dark:text-emerald-100",+ disconnected: "border-border bg-secondary text-muted-foreground",+};++const statusDotClasses: Record<string, string> = {+ running: "bg-sky-200",+ connecting: "bg-amber-200",+ ready: "bg-emerald-200",+ disconnected: "bg-muted-foreground/40",+};

Then use:

<divclassName={cn("inline-flex items-center gap-2 rounded-full border px-2.5 py-1 text-[10px]",statusContainerClasses[phase]??statusContainerClasses.disconnected)}>

Based on learnings: "Use Tailwind CSS for styling - no inline styles, use cn for conditional classes".

apps/renderer/src/components/Sidebar.tsx (1)

138-152: Prefer Coss UI for the new icon-only theme toggle.

To keep styling and interaction patterns consistent with the rest of the app, consider swapping this raw <button> for the equivalent Coss UI icon/button primitive.

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling.

Add light/dark/system theme cycling and apply token-based theming across Sidebar, ChatView, and global styles to introduce light mode

Introduce a useTheme hook with localStorage persistence and a Sidebar header button to cycle system/light/dark; switch global and app styling to CSS variables and semantic Tailwind tokens; refactor ChatView and Sidebar UI to use shared UI primitives; remove thread status badges, editor/approval flows, and keyboard shortcuts; update model selection in new project flow.

📍Where to Start

Start with the useTheme hook in useTheme.ts and its integration in the Sidebar in Sidebar.tsx, then review theme token application in index.css.

🧹 Nitpick comments (6)

apps/renderer/src/components/ui/table.tsx (1)

36-47: Consider extracting long class strings for maintainability.

The class string on line 40 is quite long with many frame-conditional styles. While this is a common pattern in shadcn-style UI libraries, consider extracting the frame-specific styles into a separate variable or using Tailwind's @apply directive in a CSS file for better readability.

That said, this is a stylistic preference and the current implementation is functionally correct.

apps/renderer/src/components/ui/separator.tsx (1)

13-13: The CSS selector for vertical self-stretch is fragile and likely won't work as intended.

The selector not-[[class^='h-']]:not-[[class*='_h-']] checks whether the class attribute string starts with 'h-' or contains '_h-'. Since other classes (e.g., shrink-0) will appear first in the composed className, the [class^='h-'] condition will almost never match—even when a height utility like h-10 is present.

Consider simplifying by always applying self-stretch for vertical orientation and letting explicit height classes override it naturally, or document that consumers should use inline styles / CSS variables for custom heights:

♻️ Suggested simplification

- "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:w-px data-[orientation=vertical]:not-[[class^='h-']]:not-[[class*='_h-']]:self-stretch",+ "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:h-full data-[orientation=vertical]:w-px",

The toast content rendering here (icon, title, description, action button) is nearly identical to lines 128-158 in the Toasts component. Extracting this into a shared ToastContent component would reduce duplication and ensure consistency when making future changes.

5-26: Prefer Coss UI primitives for consistency.

These custom Kbd/KbdGroup wrappers diverge from the guideline to use Coss UI components (installed via the ShadCN CLI) for consistent styling and Base UI accessibility alignment. If a Coss kbd component exists, consider swapping to it (or document why bespoke wrappers are required).

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling. Install new components using the ShadCN CLI (e.g., bunx --bun shadcnlatest add coss/button). Refer to Base UI docs for accessibility guidelines on primitives.

apps/renderer/src/components/ui/textarea.tsx (1)

7-10: Consider documenting or removing the number type for size.

The size prop accepts "sm" | "default" | "lg" | number, but the internal styling logic (lines 35-38) only handles the string literals. When a number is passed, it's set on data-size but no corresponding styles are applied.

If numeric sizes are intended for custom CSS handling via data-size, consider adding a brief comment documenting this. Otherwise, consider restricting the type to the supported string literals only.

apps/renderer/src/index.css (1)

227-242: Consider using CSS variables for scrollbar colors for consistency.

The scrollbar styling uses hardcoded rgba() values while the rest of the file uses CSS variables. For better theme consistency, consider using the defined tokens:

♻️ Optional: Use CSS variables for scrollbar colors

 ::-webkit-scrollbar-thumb {
- background: rgba(0, 0, 0, 0.15);+ background: var(--muted-foreground);+ opacity: 0.15;
border-radius: 3px;
}
::-webkit-scrollbar-thumb:hover {
- background: rgba(0, 0, 0, 0.25);+ background: var(--muted-foreground);+ opacity: 0.25;
}
.dark ::-webkit-scrollbar-thumb {
- background: rgba(255, 255, 255, 0.1);+ background: var(--muted-foreground);+ opacity: 0.1;
}
.dark ::-webkit-scrollbar-thumb:hover {
- background: rgba(255, 255, 255, 0.18);+ background: var(--muted-foreground);+ opacity: 0.18;
}

Note: Opacity on scrollbar thumbs may have limited browser support; the current approach works reliably.

Avoid the disabled prop; use aria-disabled and a click guard instead.

The current disabled usage conflicts with the repo’s accessibility guidance and can break tooltips. Use styling plus a guard in the handler.

the top of handlePickFolder (or inline in the onClick wrapper) that returns
early if isPickingFolder so clicks are ignored; ensure tooltip behavior is

Replace with Coss UI ScrollArea component for consistency with codebase guidelines.

Coss UI provides a ScrollArea component that should be installed via ShadCN CLI: pnpm dlx shadcn@latest add @coss/scroll-area``. The custom extensions (scrollFade, `scrollbarGutter`) can be preserved by wrapping the Coss UI component instead of using Base UI directly. This ensures alignment with the team's component catalog and styling standards.

Walkthrough

Adds a large set of new UI components and utilities to the renderer, introduces a CSS-variable based theme (light/dark/system) and a useTheme hook, replaces hard-coded color tokens with semantic tokens across core renderer components, adds a cn utility and components.json, adjusts deps/config and a small smoke-test script tweak.

Changes

Cohort / File(s)	Summary
UI component library apps/renderer/src/components/ui/*	Adds 30+ new UI modules (accordion, alert, autocomplete, avatar, badge, button, card, checkbox, collapsible, combobox, command, dialog, empty, field, fieldset, form, input-group, input, kbd, label, menu, popover, progress, radio-group, scroll-area, select, separator, sheet, skeleton, spinner, switch, table, tabs, textarea, toast). Each wraps @base-ui/react primitives, applies data-slot attributes, CVA variants and composed Tailwind classes. Review API shapes, typings, and consistent class/slot usage.
Core renderer components apps/renderer/src/App.tsx, apps/renderer/src/components/ChatView.tsx, apps/renderer/src/components/ChatMarkdown.tsx, apps/renderer/src/components/DiffPanel.tsx, apps/renderer/src/components/Sidebar.tsx	Replaces hex color classes with semantic tokens; ChatView integrates new InputGroup, Select, Button components and removes previous textarea auto-resize logic; ChatMarkdown and DiffPanel styling tokens updated; Sidebar adds theme toggle and theme-aware styling. Validate behavioral changes where logic was removed (e.g., textarea resizing, model menu handling).
Theming & CSS apps/renderer/src/index.css, apps/renderer/src/hooks/useTheme.ts	Introduces CSS variable theme system with light/dark variants and a .no-transitions helper; adds many CSS token definitions and dark overrides. Adds useTheme hook (light
Utilities & small libs apps/renderer/src/lib/utils.ts, apps/renderer/components.json	Adds cn(...inputs) util combining clsx + twMerge. Adds components.json with UI framework config, aliases, Tailwind/tokens and registries. Confirm imports use the new alias and utility.
Config & build apps/renderer/tsconfig.json, apps/renderer/vite.config.ts, biome.json	Adds #/* path alias and resolves # in Vite; sets exactOptionalPropertyTypes: false in tsconfig; relaxes biome a11y rule noSvgWithoutTitle.
Dependencies apps/renderer/package.json	Adds runtime deps including @base-ui/react, class-variance-authority, clsx, lucide-react, tailwind-merge and reorders react-markdown. Verify lockfile and install.
Markup & scripts apps/renderer/index.html, apps/desktop/scripts/smoke-test.mjs	Removes body Tailwind class in index.html. Small smoke-test script tweak: reorder imports from node:child_process and use template literal for error output. Minor script change.

312-344: Consider using cn utility for conditional class handling.

Then use:

<divclassName={cn("inline-flex items-center gap-2 rounded-full border px-2.5 py-1 text-[10px]",statusContainerClasses[phase]??statusContainerClasses.disconnected)}>

To keep styling and interaction patterns consistent with the rest of the app, consider swapping this raw <button> for the equivalent Coss UI icon/button primitive.

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling.

Add light/dark/system theme cycling and apply token-based theming across Sidebar, ChatView, and global styles to introduce light mode

Introduce a useTheme hook with localStorage persistence and a Sidebar header button to cycle system/light/dark; switch global and app styling to CSS variables and semantic Tailwind tokens; refactor ChatView and Sidebar UI to use shared UI primitives; remove thread status badges, editor/approval flows, and keyboard shortcuts; update model selection in new project flow.

📍Where to Start

Start with the useTheme hook in useTheme.ts and its integration in the Sidebar in Sidebar.tsx, then review theme token application in index.css.

In `@apps/renderer/src/components/Sidebar.tsx`:
- Around line 225-230: The button currently uses the disabled prop which
conflicts with accessibility guidance and tooltips; instead remove the disabled
attribute on the button element, add aria-disabled={isPickingFolder} to reflect
state, keep/adjust the visual "disabled" classes conditionally when
isPickingFolder, and add a click guard at the top of handlePickFolder (or inline
in the onClick wrapper) that returns early if isPickingFolder so clicks are
ignored; ensure tooltip behavior is preserved by using aria-disabled rather than
disabled.
In `@apps/renderer/src/components/ui/combobox.tsx`:
- Around line 196-214: The SVG in the Combobox component uses an incorrect xmlns
value; update the xmlns on the SVG inside ComboboxPrimitive.ItemIndicator to the
correct "http://www.w3.org/2000/svg" string so the icon renders properly (look
for the SVG element in the ComboboxPrimitive.ItemIndicator within the
combobox.tsx component and change the xmlns attribute value).
In `@apps/renderer/src/components/ui/empty.tsx`:
- Around line 94-105: The component EmptyDescription is typed as
React.ComponentProps<"p"> but renders a <div>, causing a props/semantic
mismatch; fix it by making the types and markup consistent—either change the
rendered element to <p> (keep the same props type) or change the prop type to
React.ComponentProps<"div"> (keep the <div>); update the function signature
(EmptyDescription) accordingly and ensure spreading {...props}, className and
data-slot="empty-description" remain correct for the chosen element.
In `@apps/renderer/src/components/ui/scroll-area.tsx`:
- Around line 5-35: Replace the custom use of ScrollAreaPrimitive
(ScrollAreaPrimitive.Root, ScrollAreaPrimitive.Viewport,
ScrollAreaPrimitive.Corner) and the local ScrollBar components with the Coss UI
ScrollArea wrapper: install the package via the shadcn CLI (`pnpm dlx
shadcn@latest add `@coss/scroll-area``), import Coss's ScrollArea,
ScrollAreaViewport and Corner (or the exported equivalents) and re-create this
component as a thin wrapper named ScrollArea that forwards props and children
while preserving the scrollFade and scrollbarGutter booleans by mapping them to
equivalent className masks and gutter classes on the Coss component (apply the
same mask expressions and `data-has-overflow-*` gutter classes), and ensure
data-slot attributes (scroll-area-viewport, scroll-area-corner) remain on the
mapped children so existing consumers continue to work.
In `@apps/renderer/src/components/ui/select.tsx`:
- Around line 128-142: The SVG used inside SelectPrimitive.ItemIndicator has a
typo in its xmlns attribute; update the xmlns on the SVG element within
SelectPrimitive.ItemIndicator to the correct namespace
"http://www.w3.org/2000/svg" so the checkmark renders correctly across browsers
(locate the SVG in the SelectPrimitive.ItemIndicator block and replace the
incorrect "http://www.w3.org/1500/svg" value).
In `@apps/renderer/src/components/ui/skeleton.tsx`:
- Around line 1-3: The file uses React.ComponentProps<"div"> in the Skeleton
component but doesn't import the React namespace; add an import for React (e.g.,
add "import React from 'react'" or "import type React from 'react'") at the top
of apps/renderer/src/components/ui/skeleton.tsx so the React.ComponentProps type
resolves for the Skeleton function signature.

🧹 Nitpick comments (6)

apps/renderer/src/components/ui/table.tsx (1)

36-47: Consider extracting long class strings for maintainability.

The class string on line 40 is quite long with many frame-conditional styles. While this is a common pattern in shadcn-style UI libraries, consider extracting the frame-specific styles into a separate variable or using Tailwind's @apply directive in a CSS file for better readability.

That said, this is a stylistic preference and the current implementation is functionally correct.

apps/renderer/src/components/ui/separator.tsx (1)

13-13: The CSS selector for vertical self-stretch is fragile and likely won't work as intended.

The selector not-[[class^='h-']]:not-[[class*='_h-']] checks whether the class attribute string starts with 'h-' or contains '_h-'. Since other classes (e.g., shrink-0) will appear first in the composed className, the [class^='h-'] condition will almost never match—even when a height utility like h-10 is present.

Consider simplifying by always applying self-stretch for vertical orientation and letting explicit height classes override it naturally, or document that consumers should use inline styles / CSS variables for custom heights:

♻️ Suggested simplification

- "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:w-px data-[orientation=vertical]:not-[[class^='h-']]:not-[[class*='_h-']]:self-stretch",+ "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:h-full data-[orientation=vertical]:w-px",

apps/renderer/src/components/ui/toast.tsx (1)

220-250: Consider extracting shared toast content into a reusable component.

The toast content rendering here (icon, title, description, action button) is nearly identical to lines 128-158 in the Toasts component. Extracting this into a shared ToastContent component would reduce duplication and ensure consistency when making future changes.

♻️ Suggested extraction

// Shared component to use in both Toasts and AnchoredToastsfunctionToastContentBody({ toast }: {toast: Toast.ToastObject}){constIcon=toast.type
? TOAST_ICONS[toast.typeaskeyoftypeofTOAST_ICONS]
: null;return(<Toast.ContentclassName="pointer-events-auto flex items-center justify-between gap-1.5 overflow-hidden px-3.5 py-3 text-sm ..."><divclassName="flex gap-2">{Icon&&(<divclassName="[&>svg]:h-lh [&>svg]:w-4 [&_svg]:pointer-events-none [&_svg]:shrink-0"data-slot="toast-icon"><IconclassName="in-data-[type=loading]:animate-spin ..."/></div>)}<divclassName="flex flex-col gap-0.5"><Toast.TitleclassName="font-medium"data-slot="toast-title"/><Toast.DescriptionclassName="text-muted-foreground"data-slot="toast-description"/></div></div>{toast.actionProps&&(<Toast.ActionclassName={buttonVariants({size: "xs"})}data-slot="toast-action">{toast.actionProps.children}</Toast.Action>)}</Toast.Content>);}

apps/renderer/src/components/ui/kbd.tsx (1)

5-26: Prefer Coss UI primitives for consistency.

These custom Kbd/KbdGroup wrappers diverge from the guideline to use Coss UI components (installed via the ShadCN CLI) for consistent styling and Base UI accessibility alignment. If a Coss kbd component exists, consider swapping to it (or document why bespoke wrappers are required).

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling. Install new components using the ShadCN CLI (e.g., bunx --bun shadcnlatest add coss/button). Refer to Base UI docs for accessibility guidelines on primitives.

apps/renderer/src/components/ui/textarea.tsx (1)

7-10: Consider documenting or removing the number type for size.

The size prop accepts "sm" | "default" | "lg" | number, but the internal styling logic (lines 35-38) only handles the string literals. When a number is passed, it's set on data-size but no corresponding styles are applied.

If numeric sizes are intended for custom CSS handling via data-size, consider adding a brief comment documenting this. Otherwise, consider restricting the type to the supported string literals only.

apps/renderer/src/index.css (1)

227-242: Consider using CSS variables for scrollbar colors for consistency.

The scrollbar styling uses hardcoded rgba() values while the rest of the file uses CSS variables. For better theme consistency, consider using the defined tokens:

♻️ Optional: Use CSS variables for scrollbar colors

 ::-webkit-scrollbar-thumb {
- background: rgba(0, 0, 0, 0.15);+ background: var(--muted-foreground);+ opacity: 0.15;
border-radius: 3px;
}
::-webkit-scrollbar-thumb:hover {
- background: rgba(0, 0, 0, 0.25);+ background: var(--muted-foreground);+ opacity: 0.25;
}
.dark ::-webkit-scrollbar-thumb {
- background: rgba(255, 255, 255, 0.1);+ background: var(--muted-foreground);+ opacity: 0.1;
}
.dark ::-webkit-scrollbar-thumb:hover {
- background: rgba(255, 255, 255, 0.18);+ background: var(--muted-foreground);+ opacity: 0.18;
}

Note: Opacity on scrollbar thumbs may have limited browser support; the current approach works reliably.

Avoid the disabled prop; use aria-disabled and a click guard instead.

The current disabled usage conflicts with the repo’s accessibility guidance and can break tooltips. Use styling plus a guard in the handler.

Coss UI provides a ScrollArea component that should be installed via ShadCN CLI: pnpm dlx shadcn@latest add @coss/scroll-area``.

in REASONING_OPTIONS) and use that map when rendering the SelectItem label and
when comparing to DEFAULT_REASONING, falling back to a nicer formatter (e.g.,
full word replacements or Title Case) only if a key is missing; update the
SelectItem render to use REASONING_DISPLAY_NAMES[effort] ||
fallbackFormatter(effort).

Walkthrough

Adds a large set of new UI components and utilities to the renderer, introduces a CSS-variable based theme (light/dark/system) and a useTheme hook, replaces hard-coded color tokens with semantic tokens across core renderer components, adds a cn utility and components.json, adjusts deps/config and a small smoke-test script tweak.

Changes

Cohort / File(s)	Summary
UI component library apps/renderer/src/components/ui/*	Adds 30+ new UI modules (accordion, alert, autocomplete, avatar, badge, button, card, checkbox, collapsible, combobox, command, dialog, empty, field, fieldset, form, input-group, input, kbd, label, menu, popover, progress, radio-group, scroll-area, select, separator, sheet, skeleton, spinner, switch, table, tabs, textarea, toast). Each wraps @base-ui/react primitives, applies data-slot attributes, CVA variants and composed Tailwind classes. Review API shapes, typings, and consistent class/slot usage.
Core renderer components apps/renderer/src/App.tsx, apps/renderer/src/components/ChatView.tsx, apps/renderer/src/components/ChatMarkdown.tsx, apps/renderer/src/components/DiffPanel.tsx, apps/renderer/src/components/Sidebar.tsx	Replaces hex color classes with semantic tokens; ChatView integrates new InputGroup, Select, Button components and removes previous textarea auto-resize logic; ChatMarkdown and DiffPanel styling tokens updated; Sidebar adds theme toggle and theme-aware styling. Validate behavioral changes where logic was removed (e.g., textarea resizing, model menu handling).
Theming & CSS apps/renderer/src/index.css, apps/renderer/src/hooks/useTheme.ts	Introduces CSS variable theme system with light/dark variants and a .no-transitions helper; adds many CSS token definitions and dark overrides. Adds useTheme hook (light
Utilities & small libs apps/renderer/src/lib/utils.ts, apps/renderer/components.json	Adds cn(...inputs) util combining clsx + twMerge. Adds components.json with UI framework config, aliases, Tailwind/tokens and registries. Confirm imports use the new alias and utility.
Config & build apps/renderer/tsconfig.json, apps/renderer/vite.config.ts, biome.json	Adds #/* path alias and resolves # in Vite; sets exactOptionalPropertyTypes: false in tsconfig; relaxes biome a11y rule noSvgWithoutTitle.
Dependencies apps/renderer/package.json	Adds runtime deps including @base-ui/react, class-variance-authority, clsx, lucide-react, tailwind-merge and reorders react-markdown. Verify lockfile and install.
Markup & scripts apps/renderer/index.html, apps/desktop/scripts/smoke-test.mjs	Removes body Tailwind class in index.html. Small smoke-test script tweak: reorder imports from node:child_process and use template literal for error output. Minor script change.

🧹 Recent nitpick comments

apps/renderer/src/components/ChatView.tsx (1)

312-344: Consider using cn utility for conditional class handling.

The deeply nested ternaries for status indicator styling reduce readability. Using the cn utility with object syntax would make the phase-based styling clearer and more maintainable.

♻️ Suggested refactor using cn utility

+const statusContainerClasses: Record<string, string> = {+ running: "border-sky-400/35 bg-sky-500/8 text-sky-700 dark:text-sky-100",+ connecting: "border-amber-400/35 bg-amber-500/8 text-amber-700 dark:text-amber-100",+ ready: "border-emerald-400/35 bg-emerald-500/8 text-emerald-700 dark:text-emerald-100",+ disconnected: "border-border bg-secondary text-muted-foreground",+};++const statusDotClasses: Record<string, string> = {+ running: "bg-sky-200",+ connecting: "bg-amber-200",+ ready: "bg-emerald-200",+ disconnected: "bg-muted-foreground/40",+};

Then use:

<divclassName={cn("inline-flex items-center gap-2 rounded-full border px-2.5 py-1 text-[10px]",statusContainerClasses[phase]??statusContainerClasses.disconnected)}>

Based on learnings: "Use Tailwind CSS for styling - no inline styles, use cn for conditional classes".

apps/renderer/src/components/Sidebar.tsx (1)

138-152: Prefer Coss UI for the new icon-only theme toggle.

To keep styling and interaction patterns consistent with the rest of the app, consider swapping this raw <button> for the equivalent Coss UI icon/button primitive.

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling.

Add light/dark/system theme cycling and apply token-based theming across Sidebar, ChatView, and global styles to introduce light mode

Introduce a useTheme hook with localStorage persistence and a Sidebar header button to cycle system/light/dark; switch global and app styling to CSS variables and semantic Tailwind tokens; refactor ChatView and Sidebar UI to use shared UI primitives; remove thread status badges, editor/approval flows, and keyboard shortcuts; update model selection in new project flow.

📍Where to Start

Start with the useTheme hook in useTheme.ts and its integration in the Sidebar in Sidebar.tsx, then review theme token application in index.css.

In `@apps/renderer/src/components/Sidebar.tsx`:
- Around line 225-230: The button currently uses the disabled prop which
conflicts with accessibility guidance and tooltips; instead remove the disabled
attribute on the button element, add aria-disabled={isPickingFolder} to reflect
state, keep/adjust the visual "disabled" classes conditionally when
isPickingFolder, and add a click guard at the top of handlePickFolder (or inline
in the onClick wrapper) that returns early if isPickingFolder so clicks are
ignored; ensure tooltip behavior is preserved by using aria-disabled rather than
disabled.
In `@apps/renderer/src/components/ui/combobox.tsx`:
- Around line 196-214: The SVG in the Combobox component uses an incorrect xmlns
value; update the xmlns on the SVG inside ComboboxPrimitive.ItemIndicator to the
correct "http://www.w3.org/2000/svg" string so the icon renders properly (look
for the SVG element in the ComboboxPrimitive.ItemIndicator within the
combobox.tsx component and change the xmlns attribute value).
In `@apps/renderer/src/components/ui/empty.tsx`:
- Around line 94-105: The component EmptyDescription is typed as
React.ComponentProps<"p"> but renders a <div>, causing a props/semantic
mismatch; fix it by making the types and markup consistent—either change the
rendered element to <p> (keep the same props type) or change the prop type to
React.ComponentProps<"div"> (keep the <div>); update the function signature
(EmptyDescription) accordingly and ensure spreading {...props}, className and
data-slot="empty-description" remain correct for the chosen element.
In `@apps/renderer/src/components/ui/scroll-area.tsx`:
- Around line 5-35: Replace the custom use of ScrollAreaPrimitive
(ScrollAreaPrimitive.Root, ScrollAreaPrimitive.Viewport,
ScrollAreaPrimitive.Corner) and the local ScrollBar components with the Coss UI
ScrollArea wrapper: install the package via the shadcn CLI (`pnpm dlx
shadcn@latest add `@coss/scroll-area``), import Coss's ScrollArea,
ScrollAreaViewport and Corner (or the exported equivalents) and re-create this
component as a thin wrapper named ScrollArea that forwards props and children
while preserving the scrollFade and scrollbarGutter booleans by mapping them to
equivalent className masks and gutter classes on the Coss component (apply the
same mask expressions and `data-has-overflow-*` gutter classes), and ensure
data-slot attributes (scroll-area-viewport, scroll-area-corner) remain on the
mapped children so existing consumers continue to work.
In `@apps/renderer/src/components/ui/select.tsx`:
- Around line 128-142: The SVG used inside SelectPrimitive.ItemIndicator has a
typo in its xmlns attribute; update the xmlns on the SVG element within
SelectPrimitive.ItemIndicator to the correct namespace
"http://www.w3.org/2000/svg" so the checkmark renders correctly across browsers
(locate the SVG in the SelectPrimitive.ItemIndicator block and replace the
incorrect "http://www.w3.org/1500/svg" value).
In `@apps/renderer/src/components/ui/skeleton.tsx`:
- Around line 1-3: The file uses React.ComponentProps<"div"> in the Skeleton
component but doesn't import the React namespace; add an import for React (e.g.,
add "import React from 'react'" or "import type React from 'react'") at the top
of apps/renderer/src/components/ui/skeleton.tsx so the React.ComponentProps type
resolves for the Skeleton function signature.

🧹 Nitpick comments (6)

apps/renderer/src/components/ui/table.tsx (1)

36-47: Consider extracting long class strings for maintainability.

The class string on line 40 is quite long with many frame-conditional styles. While this is a common pattern in shadcn-style UI libraries, consider extracting the frame-specific styles into a separate variable or using Tailwind's @apply directive in a CSS file for better readability.

That said, this is a stylistic preference and the current implementation is functionally correct.

apps/renderer/src/components/ui/separator.tsx (1)

13-13: The CSS selector for vertical self-stretch is fragile and likely won't work as intended.

The selector not-[[class^='h-']]:not-[[class*='_h-']] checks whether the class attribute string starts with 'h-' or contains '_h-'. Since other classes (e.g., shrink-0) will appear first in the composed className, the [class^='h-'] condition will almost never match—even when a height utility like h-10 is present.

Consider simplifying by always applying self-stretch for vertical orientation and letting explicit height classes override it naturally, or document that consumers should use inline styles / CSS variables for custom heights:

♻️ Suggested simplification

- "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:w-px data-[orientation=vertical]:not-[[class^='h-']]:not-[[class*='_h-']]:self-stretch",+ "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:h-full data-[orientation=vertical]:w-px",

apps/renderer/src/components/ui/toast.tsx (1)

220-250: Consider extracting shared toast content into a reusable component.

The toast content rendering here (icon, title, description, action button) is nearly identical to lines 128-158 in the Toasts component. Extracting this into a shared ToastContent component would reduce duplication and ensure consistency when making future changes.

♻️ Suggested extraction

// Shared component to use in both Toasts and AnchoredToastsfunctionToastContentBody({ toast }: {toast: Toast.ToastObject}){constIcon=toast.type
? TOAST_ICONS[toast.typeaskeyoftypeofTOAST_ICONS]
: null;return(<Toast.ContentclassName="pointer-events-auto flex items-center justify-between gap-1.5 overflow-hidden px-3.5 py-3 text-sm ..."><divclassName="flex gap-2">{Icon&&(<divclassName="[&>svg]:h-lh [&>svg]:w-4 [&_svg]:pointer-events-none [&_svg]:shrink-0"data-slot="toast-icon"><IconclassName="in-data-[type=loading]:animate-spin ..."/></div>)}<divclassName="flex flex-col gap-0.5"><Toast.TitleclassName="font-medium"data-slot="toast-title"/><Toast.DescriptionclassName="text-muted-foreground"data-slot="toast-description"/></div></div>{toast.actionProps&&(<Toast.ActionclassName={buttonVariants({size: "xs"})}data-slot="toast-action">{toast.actionProps.children}</Toast.Action>)}</Toast.Content>);}

apps/renderer/src/components/ui/kbd.tsx (1)

5-26: Prefer Coss UI primitives for consistency.

These custom Kbd/KbdGroup wrappers diverge from the guideline to use Coss UI components (installed via the ShadCN CLI) for consistent styling and Base UI accessibility alignment. If a Coss kbd component exists, consider swapping to it (or document why bespoke wrappers are required).

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling. Install new components using the ShadCN CLI (e.g., bunx --bun shadcnlatest add coss/button). Refer to Base UI docs for accessibility guidelines on primitives.

apps/renderer/src/components/ui/textarea.tsx (1)

7-10: Consider documenting or removing the number type for size.

The size prop accepts "sm" | "default" | "lg" | number, but the internal styling logic (lines 35-38) only handles the string literals. When a number is passed, it's set on data-size but no corresponding styles are applied.

If numeric sizes are intended for custom CSS handling via data-size, consider adding a brief comment documenting this. Otherwise, consider restricting the type to the supported string literals only.

apps/renderer/src/index.css (1)

227-242: Consider using CSS variables for scrollbar colors for consistency.

The scrollbar styling uses hardcoded rgba() values while the rest of the file uses CSS variables. For better theme consistency, consider using the defined tokens:

♻️ Optional: Use CSS variables for scrollbar colors

 ::-webkit-scrollbar-thumb {
- background: rgba(0, 0, 0, 0.15);+ background: var(--muted-foreground);+ opacity: 0.15;
border-radius: 3px;
}
::-webkit-scrollbar-thumb:hover {
- background: rgba(0, 0, 0, 0.25);+ background: var(--muted-foreground);+ opacity: 0.25;
}
.dark ::-webkit-scrollbar-thumb {
- background: rgba(255, 255, 255, 0.1);+ background: var(--muted-foreground);+ opacity: 0.1;
}
.dark ::-webkit-scrollbar-thumb:hover {
- background: rgba(255, 255, 255, 0.18);+ background: var(--muted-foreground);+ opacity: 0.18;
}

Note: Opacity on scrollbar thumbs may have limited browser support; the current approach works reliably.

⚠️ Potential issue | 🟡 Minor

Avoid the disabled prop; use aria-disabled and a click guard instead.

The current disabled usage conflicts with the repo’s accessibility guidance and can break tooltips. Use styling plus a guard in the handler.

🛠️ Suggested fix

Coss UI provides a ScrollArea component that should be installed via ShadCN CLI: pnpm dlx shadcn@latest add @coss/scroll-area``. The custom extensions (scrollFade, `scrollbarGutter`) can be preserved by wrapping the Coss UI component instead of using Base UI directly.

Add React type import for ComponentProps reference.

Line 3 references React.ComponentProps<"div"> without importing the React namespace. While the modern JSX transform (jsx: "react-jsx") eliminates the need for React in JSX elements, explicit namespace references like React.ComponentProps still require the import and will cause a type-checking error.

Capitalization of "xhigh" produces awkward "Xhigh" in the UI.

The inline capitalization effort.charAt(0).toUpperCase() + effort.slice(1) transforms "xhigh" to "Xhigh", which isn't user-friendly. Consider a display name mapping for better readability.

Walkthrough

Adds a large set of new UI components and utilities to the renderer, introduces a CSS-variable based theme (light/dark/system) and a useTheme hook, replaces hard-coded color tokens with semantic tokens across core renderer components, adds a cn utility and components.json, adjusts deps/config and a small smoke-test script tweak.

Changes

Cohort / File(s)	Summary
UI component library apps/renderer/src/components/ui/*	Adds 30+ new UI modules (accordion, alert, autocomplete, avatar, badge, button, card, checkbox, collapsible, combobox, command, dialog, empty, field, fieldset, form, input-group, input, kbd, label, menu, popover, progress, radio-group, scroll-area, select, separator, sheet, skeleton, spinner, switch, table, tabs, textarea, toast). Each wraps @base-ui/react primitives, applies data-slot attributes, CVA variants and composed Tailwind classes. Review API shapes, typings, and consistent class/slot usage.
Core renderer components apps/renderer/src/App.tsx, apps/renderer/src/components/ChatView.tsx, apps/renderer/src/components/ChatMarkdown.tsx, apps/renderer/src/components/DiffPanel.tsx, apps/renderer/src/components/Sidebar.tsx	Replaces hex color classes with semantic tokens; ChatView integrates new InputGroup, Select, Button components and removes previous textarea auto-resize logic; ChatMarkdown and DiffPanel styling tokens updated; Sidebar adds theme toggle and theme-aware styling. Validate behavioral changes where logic was removed (e.g., textarea resizing, model menu handling).
Theming & CSS apps/renderer/src/index.css, apps/renderer/src/hooks/useTheme.ts	Introduces CSS variable theme system with light/dark variants and a .no-transitions helper; adds many CSS token definitions and dark overrides. Adds useTheme hook (light
Utilities & small libs apps/renderer/src/lib/utils.ts, apps/renderer/components.json	Adds cn(...inputs) util combining clsx + twMerge. Adds components.json with UI framework config, aliases, Tailwind/tokens and registries. Confirm imports use the new alias and utility.
Config & build apps/renderer/tsconfig.json, apps/renderer/vite.config.ts, biome.json	Adds #/* path alias and resolves # in Vite; sets exactOptionalPropertyTypes: false in tsconfig; relaxes biome a11y rule noSvgWithoutTitle.
Dependencies apps/renderer/package.json	Adds runtime deps including @base-ui/react, class-variance-authority, clsx, lucide-react, tailwind-merge and reorders react-markdown. Verify lockfile and install.
Markup & scripts apps/renderer/index.html, apps/desktop/scripts/smoke-test.mjs	Removes body Tailwind class in index.html. Small smoke-test script tweak: reorder imports from node:child_process and use template literal for error output. Minor script change.

apps/renderer/src/components/ChatView.tsx (1)

312-344: Consider using cn utility for conditional class handling.

The deeply nested ternaries for status indicator styling reduce readability. Using the cn utility with object syntax would make the phase-based styling clearer and more maintainable.

♻️ Suggested refactor using cn utility

+const statusContainerClasses: Record<string, string> = {+ running: "border-sky-400/35 bg-sky-500/8 text-sky-700 dark:text-sky-100",+ connecting: "border-amber-400/35 bg-amber-500/8 text-amber-700 dark:text-amber-100",+ ready: "border-emerald-400/35 bg-emerald-500/8 text-emerald-700 dark:text-emerald-100",+ disconnected: "border-border bg-secondary text-muted-foreground",+};++const statusDotClasses: Record<string, string> = {+ running: "bg-sky-200",+ connecting: "bg-amber-200",+ ready: "bg-emerald-200",+ disconnected: "bg-muted-foreground/40",+};

Then use:

<divclassName={cn("inline-flex items-center gap-2 rounded-full border px-2.5 py-1 text-[10px]",statusContainerClasses[phase]??statusContainerClasses.disconnected)}>

Based on learnings: "Use Tailwind CSS for styling - no inline styles, use cn for conditional classes".

138-152: Prefer Coss UI for the new icon-only theme toggle.

To keep styling and interaction patterns consistent with the rest of the app, consider swapping this raw <button> for the equivalent Coss UI icon/button primitive.

Add light/dark/system theme cycling and apply token-based theming across Sidebar, ChatView, and global styles to introduce light mode

Introduce a useTheme hook with localStorage persistence and a Sidebar header button to cycle system/light/dark; switch global and app styling to CSS variables and semantic Tailwind tokens; refactor ChatView and Sidebar UI to use shared UI primitives; remove thread status badges, editor/approval flows, and keyboard shortcuts; update model selection in new project flow.

📍Where to Start

Start with the useTheme hook in useTheme.ts and its integration in the Sidebar in Sidebar.tsx, then review theme token application in index.css.

ScrollAreaViewport and Corner (or the exported equivalents) and re-create this
component as a thin wrapper named ScrollArea that forwards props and children
while preserving the scrollFade and scrollbarGutter booleans by mapping them to
equivalent className masks and gutter classes on the Coss component (apply the
same mask expressions and `data-has-overflow-*` gutter classes), and ensure
data-slot attributes (scroll-area-viewport, scroll-area-corner) remain on the
mapped children so existing consumers continue to work.

🧹 Nitpick comments (6)

apps/renderer/src/components/ui/table.tsx (1)

36-47: Consider extracting long class strings for maintainability.

The class string on line 40 is quite long with many frame-conditional styles. While this is a common pattern in shadcn-style UI libraries, consider extracting the frame-specific styles into a separate variable or using Tailwind's @apply directive in a CSS file for better readability.

That said, this is a stylistic preference and the current implementation is functionally correct.

apps/renderer/src/components/ui/separator.tsx (1)

13-13: The CSS selector for vertical self-stretch is fragile and likely won't work as intended.

The selector not-[[class^='h-']]:not-[[class*='_h-']] checks whether the class attribute string starts with 'h-' or contains '_h-'. Since other classes (e.g., shrink-0) will appear first in the composed className, the [class^='h-'] condition will almost never match—even when a height utility like h-10 is present.

Consider simplifying by always applying self-stretch for vertical orientation and letting explicit height classes override it naturally, or document that consumers should use inline styles / CSS variables for custom heights:

♻️ Suggested simplification

- "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:w-px data-[orientation=vertical]:not-[[class^='h-']]:not-[[class*='_h-']]:self-stretch",+ "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:h-full data-[orientation=vertical]:w-px",

apps/renderer/src/components/ui/toast.tsx (1)

220-250: Consider extracting shared toast content into a reusable component.

The toast content rendering here (icon, title, description, action button) is nearly identical to lines 128-158 in the Toasts component. Extracting this into a shared ToastContent component would reduce duplication and ensure consistency when making future changes.

♻️ Suggested extraction

// Shared component to use in both Toasts and AnchoredToastsfunctionToastContentBody({ toast }: {toast: Toast.ToastObject}){constIcon=toast.type
? TOAST_ICONS[toast.typeaskeyoftypeofTOAST_ICONS]
: null;return(<Toast.ContentclassName="pointer-events-auto flex items-center justify-between gap-1.5 overflow-hidden px-3.5 py-3 text-sm ..."><divclassName="flex gap-2">{Icon&&(<divclassName="[&>svg]:h-lh [&>svg]:w-4 [&_svg]:pointer-events-none [&_svg]:shrink-0"data-slot="toast-icon"><IconclassName="in-data-[type=loading]:animate-spin ..."/></div>)}<divclassName="flex flex-col gap-0.5"><Toast.TitleclassName="font-medium"data-slot="toast-title"/><Toast.DescriptionclassName="text-muted-foreground"data-slot="toast-description"/></div></div>{toast.actionProps&&(<Toast.ActionclassName={buttonVariants({size: "xs"})}data-slot="toast-action">{toast.actionProps.children}</Toast.Action>)}</Toast.Content>);}

apps/renderer/src/components/ui/kbd.tsx (1)

5-26: Prefer Coss UI primitives for consistency.

These custom Kbd/KbdGroup wrappers diverge from the guideline to use Coss UI components (installed via the ShadCN CLI) for consistent styling and Base UI accessibility alignment. If a Coss kbd component exists, consider swapping to it (or document why bespoke wrappers are required).

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling. Install new components using the ShadCN CLI (e.g., bunx --bun shadcnlatest add coss/button). Refer to Base UI docs for accessibility guidelines on primitives.

apps/renderer/src/components/ui/textarea.tsx (1)

7-10: Consider documenting or removing the number type for size.

The size prop accepts "sm" | "default" | "lg" | number, but the internal styling logic (lines 35-38) only handles the string literals. When a number is passed, it's set on data-size but no corresponding styles are applied.

If numeric sizes are intended for custom CSS handling via data-size, consider adding a brief comment documenting this. Otherwise, consider restricting the type to the supported string literals only.

apps/renderer/src/index.css (1)

227-242: Consider using CSS variables for scrollbar colors for consistency.

The scrollbar styling uses hardcoded rgba() values while the rest of the file uses CSS variables. For better theme consistency, consider using the defined tokens:

♻️ Optional: Use CSS variables for scrollbar colors

 ::-webkit-scrollbar-thumb {
- background: rgba(0, 0, 0, 0.15);+ background: var(--muted-foreground);+ opacity: 0.15;
border-radius: 3px;
}
::-webkit-scrollbar-thumb:hover {
- background: rgba(0, 0, 0, 0.25);+ background: var(--muted-foreground);+ opacity: 0.25;
}
.dark ::-webkit-scrollbar-thumb {
- background: rgba(255, 255, 255, 0.1);+ background: var(--muted-foreground);+ opacity: 0.1;
}
.dark ::-webkit-scrollbar-thumb:hover {
- background: rgba(255, 255, 255, 0.18);+ background: var(--muted-foreground);+ opacity: 0.18;
}

Note: Opacity on scrollbar thumbs may have limited browser support; the current approach works reliably.

Replace with Coss UI ScrollArea component for consistency with codebase guidelines.

Coss UI provides a ScrollArea component that should be installed via ShadCN CLI: pnpm dlx shadcn@latest add @coss/scroll-area``. The custom extensions (scrollFade, `scrollbarGutter`) can be preserved by wrapping the Coss UI component instead of using Base UI directly. This ensures alignment with the team's component catalog and styling standards.

ScrollAreaPrimitive.Viewport, ScrollAreaPrimitive.Corner) and the local
ScrollBar components with the Coss UI ScrollArea wrapper: install the package

Coss's ScrollArea, ScrollAreaViewport and Corner (or the exported equivalents)
and re-create this component as a thin wrapper named ScrollArea that forwards
props and children while preserving the scrollFade and scrollbarGutter booleans
by mapping them to equivalent className masks and gutter classes on the Coss
component (apply the same mask expressions and `data-has-overflow-*` gutter
classes), and ensure data-slot attributes (scroll-area-viewport,
scroll-area-corner) remain on the mapped children so existing consumers continue

Add React type import for ComponentProps reference.

While the modern JSX transform (jsx: "react-jsx") eliminates the need for React in JSX elements, explicit namespace references like React.ComponentProps still require the import and will cause a type-checking error.

apps/renderer/src/components/ChatView.tsx (1)

312-344: Consider using cn utility for conditional class handling.

The deeply nested ternaries for status indicator styling reduce readability. Using the cn utility with object syntax would make the phase-based styling clearer and more maintainable.

♻️ Suggested refactor using cn utility

+const statusContainerClasses: Record<string, string> = {+ running: "border-sky-400/35 bg-sky-500/8 text-sky-700 dark:text-sky-100",+ connecting: "border-amber-400/35 bg-amber-500/8 text-amber-700 dark:text-amber-100",+ ready: "border-emerald-400/35 bg-emerald-500/8 text-emerald-700 dark:text-emerald-100",+ disconnected: "border-border bg-secondary text-muted-foreground",+};++const statusDotClasses: Record<string, string> = {+ running: "bg-sky-200",+ connecting: "bg-amber-200",+ ready: "bg-emerald-200",+ disconnected: "bg-muted-foreground/40",+};

Then use:

<divclassName={cn("inline-flex items-center gap-2 rounded-full border px-2.5 py-1 text-[10px]",statusContainerClasses[phase]??statusContainerClasses.disconnected)}>

Based on learnings: "Use Tailwind CSS for styling - no inline styles, use cn for conditional classes".

Add light/dark/system theme cycling and apply token-based theming across Sidebar, ChatView, and global styles to introduce light mode

Introduce a useTheme hook with localStorage persistence and a Sidebar header button to cycle system/light/dark; switch global and app styling to CSS variables and semantic Tailwind tokens; refactor ChatView and Sidebar UI to use shared UI primitives; remove thread status badges, editor/approval flows, and keyboard shortcuts; update model selection in new project flow.

📍Where to Start

Start with the useTheme hook in useTheme.ts and its integration in the Sidebar in Sidebar.tsx, then review theme token application in index.css.

🧹 Nitpick comments (6)

apps/renderer/src/components/ui/table.tsx (1)

36-47: Consider extracting long class strings for maintainability.

The class string on line 40 is quite long with many frame-conditional styles. While this is a common pattern in shadcn-style UI libraries, consider extracting the frame-specific styles into a separate variable or using Tailwind's @apply directive in a CSS file for better readability.

That said, this is a stylistic preference and the current implementation is functionally correct.

apps/renderer/src/components/ui/separator.tsx (1)

13-13: The CSS selector for vertical self-stretch is fragile and likely won't work as intended.

The selector not-[[class^='h-']]:not-[[class*='_h-']] checks whether the class attribute string starts with 'h-' or contains '_h-'. Since other classes (e.g., shrink-0) will appear first in the composed className, the [class^='h-'] condition will almost never match—even when a height utility like h-10 is present.

Consider simplifying by always applying self-stretch for vertical orientation and letting explicit height classes override it naturally, or document that consumers should use inline styles / CSS variables for custom heights:

♻️ Suggested simplification

- "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:w-px data-[orientation=vertical]:not-[[class^='h-']]:not-[[class*='_h-']]:self-stretch",+ "shrink-0 bg-border data-[orientation=horizontal]:h-px data-[orientation=horizontal]:w-full data-[orientation=vertical]:h-full data-[orientation=vertical]:w-px",

apps/renderer/src/components/ui/toast.tsx (1)

220-250: Consider extracting shared toast content into a reusable component.

The toast content rendering here (icon, title, description, action button) is nearly identical to lines 128-158 in the Toasts component. Extracting this into a shared ToastContent component would reduce duplication and ensure consistency when making future changes.

♻️ Suggested extraction

// Shared component to use in both Toasts and AnchoredToastsfunctionToastContentBody({ toast }: {toast: Toast.ToastObject}){constIcon=toast.type
? TOAST_ICONS[toast.typeaskeyoftypeofTOAST_ICONS]

apps/renderer/src/components/ui/kbd.tsx (1)

5-26: Prefer Coss UI primitives for consistency.

These custom Kbd/KbdGroup wrappers diverge from the guideline to use Coss UI components (installed via the ShadCN CLI) for consistent styling and Base UI accessibility alignment. If a Coss kbd component exists, consider swapping to it (or document why bespoke wrappers are required).

Based on learnings: Applies to **/*.tsx : Use Coss UI components (https://coss.com/ui) for consistent styling. Install new components using the ShadCN CLI (e.g., bunx --bun shadcnlatest add coss/button). Refer to Base UI docs for accessibility guidelines on primitives.

apps/renderer/src/components/ui/textarea.tsx (1)

7-10: Consider documenting or removing the number type for size.

The size prop accepts "sm" | "default" | "lg" | number, but the internal styling logic (lines 35-38) only handles the string literals. When a number is passed, it's set on data-size but no corresponding styles are applied.

If numeric sizes are intended for custom CSS handling via data-size, consider adding a brief comment documenting this. Otherwise, consider restricting the type to the supported string literals only.

apps/renderer/src/index.css (1)

227-242: Consider using CSS variables for scrollbar colors for consistency.

The scrollbar styling uses hardcoded rgba() values while the rest of the file uses CSS variables. For better theme consistency, consider using the defined tokens:

♻️ Optional: Use CSS variables for scrollbar colors

 ::-webkit-scrollbar-thumb {
- background: rgba(0, 0, 0, 0.15);+ background: var(--muted-foreground);+ opacity: 0.15;
border-radius: 3px;
}
::-webkit-scrollbar-thumb:hover {
- background: rgba(0, 0, 0, 0.25);+ background: var(--muted-foreground);+ opacity: 0.25;
}
.dark ::-webkit-scrollbar-thumb {
- background: rgba(255, 255, 255, 0.1);+ background: var(--muted-foreground);+ opacity: 0.1;
}
.dark ::-webkit-scrollbar-thumb:hover {
- background: rgba(255, 255, 255, 0.18);+ background: var(--muted-foreground);+ opacity: 0.18;
}

Note: Opacity on scrollbar thumbs may have limited browser support; the current approach works reliably.

Type mismatch: Component typed as <p> but renders <div>.

EmptyDescription accepts React.ComponentProps<"p"> but renders a <div>. This inconsistency could confuse consumers and allows <p>-specific props that won't apply to the rendered <div>.

💡 Proposed fix

Either change the rendered element to match the type:

-function EmptyDescription({ className, ...props }: React.ComponentProps<"p">) {+function EmptyDescription({ className, ...props }: React.ComponentProps<"div">) {
return (
<div

Or render a <p> to match the type (if semantically appropriate):

 function EmptyDescription({ className, ...props }: React.ComponentProps<"p">) {
return (
- <div+ <p
className={cn(
"text-muted-foreground text-sm [&>a:hover]:text-primary [&>a]:underline [&>a]:underline-offset-4 [[data-slot=empty-title]+&]:mt-1",

Replace with Coss UI ScrollArea component for consistency with codebase guidelines.

Coss UI provides a ScrollArea component that should be installed via ShadCN CLI: pnpm dlx shadcn@latest add @coss/scroll-area``. The custom extensions (scrollFade, `scrollbarGutter`) can be preserved by wrapping the Coss UI component instead of using Base UI directly. This ensures alignment with the team's component catalog and styling standards.

Coss's ScrollArea, ScrollAreaViewport and Corner (or the exported equivalents)
and re-create this component as a thin wrapper named ScrollArea that forwards
props and children while preserving the scrollFade and scrollbarGutter booleans
by mapping them to equivalent className masks and gutter classes on the Coss
component (apply the same mask expressions and `data-has-overflow-*` gutter
classes), and ensure data-slot attributes (scroll-area-viewport,

Add React type import for ComponentProps reference.

Line 3 references React.ComponentProps<"div"> without importing the React namespace. While the modern JSX transform (jsx: "react-jsx") eliminates the need for React in JSX elements, explicit namespace references like React.ComponentProps still require the import and will cause a type-checking error.

451-456: Minor: Redundant dark: prefixes for transparent and semantic tokens.

bg-transparent is identical in both modes, and bg-accent is a semantic token that already adapts to the theme. The dark: prefixes are unnecessary here.

⚠️ Potential issue | 🟡 Minor

Capitalization of "xhigh" produces awkward "Xhigh" in the UI.

The inline capitalization effort.charAt(0).toUpperCase() + effort.slice(1) transforms "xhigh" to "Xhigh", which isn't user-friendly. Consider a display name mapping for better readability.

💡 Suggested approach

+const EFFORT_LABELS: Record<string, string> = {+ xhigh: "Extra High",+ high: "High",+ medium: "Medium",+ low: "Low",+};+
{REASONING_OPTIONS.map((effort) => (
<SelectItem key={effort} value={effort}>
