Plan: Code Mode UI — Orange Input, Design System Context, File Browser Context

Context

The user wants three connected features that enhance the coding experience in AIUI:

1. Visual indication when in code mode (orange input container, "Code" label)
2. Ability to select design system items as coding context
3. Ability to select files from file browser as coding context

After this, the user wants to circle back and create a flawless version of content extraction/tab surfacing.

Changes

1. Orange Code Mode Input Container

Files: ChatWindow.vue, ChatInput.vue

ChatWindow.vue (line 106-115):

• Pass activeTab to ChatInput as a prop: :active-tab="activeTab"
• Change placeholder logic: activeTab === 'code' ? 'Code...' : isStreaming ? 'Waiting for response...' : 'Message AIUI...'

ChatInput.vue:

• Add activeTab prop (optional string, default '')
• Conditionally style the container div (line 79-81):
  • When activeTab === 'code': use bg-accent/15 border border-accent/25 backdrop-blur-xl instead of path-glass-bubble
  • Keep the rounded-2xl px-4 py-3 flex items-end gap-2 transition-all duration-300 classes
• Conditionally style the send button orange when in code mode

2. Design System Item Selection for Coding Context

Files: useCodeContext.ts, DesignSystemGrid.vue

useCodeContext.ts:

• Add selectedDesignTokens: ref<string[]>([]) to module state (stores item IDs)
• Add toggleDesignToken(id) — adds/removes from selection array
• Add clearDesignTokens() — clears selection
• Add isDesignTokenSelected(id) — checks if item is in selection
• Clear on exitCodeMode()
• Export all new state/actions

DesignSystemGrid.vue:

• Import useCodeContext
• When codeMode is true, show a selection indicator (accent ring + checkmark) on items
• selectItem should call toggleDesignToken(item.id) when in code mode (instead of openDesignSystemItem)
• When NOT in code mode, keep existing behavior (open detail view)
• Selected items get ring-2 ring-accent/50 bg-accent/10 styling

3. File Browser Selection for Coding Context

Files: useCodeContext.ts, ProjectGrid.vue

useCodeContext.ts:

• Add selectedFiles: ref<string[]>([]) — paths of files selected for context
• Add toggleFileSelection(path) — adds/removes from selection
• Add clearFileSelection() — clears all
• Add isFileSelected(path) — checks if file in selection
• Clear on exitCodeMode()
• Export new state/actions

ProjectGrid.vue:

• Import useCodeContext
• When codeMode is true, file clicks toggle selection instead of (or in addition to) opening
• Show visual selection state (accent highlight/checkmark) on selected files in FileTreeNode

Files to Modify

1. packages/app/src/components/chat/ChatWindow.vue — pass activeTab prop
2. packages/app/src/components/chat/ChatInput.vue — conditional orange styling + "Code" placeholder
3. packages/app/src/composables/useCodeContext.ts — add design token + file selection state
4. packages/app/src/components/content/DesignSystemGrid.vue — toggle selection in code mode
5. packages/app/src/components/content/ProjectGrid.vue — toggle file selection in code mode

Verification

1. pnpm typecheck — no type errors
2. pnpm lint — no new lint errors
3. Manual: /code command → input turns orange with "Code..." placeholder
4. Manual: In code mode, design system tab → clicking items toggles selection (accent ring)
5. Manual: In code mode, file browser → clicking files toggles selection
6. Manual: Exiting code mode clears all selections
