-### GOOD proposal (fundamentally different approach):
-```
-"title": "Card Grid Dashboard",
-"concept": "Replace the current vertical list layout with a responsive card grid. Each item becomes a self-contained card with an image thumbnail, title, and action buttons, improving scannability and visual density.",
-"plan": [
-  "Read src/pages/Dashboard.tsx to understand current list rendering logic",
-  "Edit src/pages/Dashboard.tsx: replace map() list items with CSS Grid card components, 3 columns on desktop, 1 on mobile",
-  "Edit src/styles/Dashboard.module.css: add grid-template-columns: repeat(auto-fill, minmax(300px, 1fr)) and card styling with border-radius, shadow, and hover elevation"
-]
-```
-
-### BAD proposal (superficial difference only -- DO NOT do this):
-```
-"title": "Blue Theme Dashboard",
-"concept": "Change the color scheme from gray to blue for a more modern look.",
-"plan": [
-  "Edit src/styles/Dashboard.module.css: change background-color from #f5f5f5 to #e3f2fd"

-This is bad because it only changes colors without altering layout, hierarchy, or interaction patterns.

-    }},
-    {{
-      "title": "Tabbed Category Dashboard",

-    }},
-    {{
-      "title": "Sidebar Navigation Dashboard",
-      "concept": "Move the dashboard navigation into a collapsible sidebar. The main content area expands to use full width, providing more space for data display.",
-      "plan": [

 ## Output
 
 You may think and explain your reasoning in intermediate messages. However, your LAST message must be ONLY a pure JSON object — no markdown, no explanation, no code blocks.

 Before outputting JSON, verify ALL of the following:
 
 1. **Required fields**: Every proposal has "title", "concept", "plan", "files", "complexity"
-2. **title**: Non-empty string, max 50 characters
-3. **concept**: 2-3 sentences explaining the design approach (not just "improve the UI")
+2. **title**: Concise, max 30 characters. Short and punchy — just the design approach name (e.g., "Card Grid Layout", "Tabbed Navigation")
+3. **concept**: 5-10 sentences of detailed, professional design rationale. Must include:
+   - What specific UI/UX problem this proposal solves
+   - The design principle or pattern being applied (with specific style name if from Design System Reference)
+   - Concrete visual details: colors (hex codes), typography (font names), spacing, border-radius, shadows
+   - How the user experience improves (scannability, navigation efficiency, visual hierarchy, etc.)
+   - Responsive behavior (how it adapts to different screen sizes)
+   Do NOT write vague concepts like "improve the UI" or "make it look modern". Be specific and professional.
 4. **plan**: Array of 2+ steps. Each step names a specific file path AND describes a specific change (not "update styles" but "add flexbox grid with 3 columns"). Steps are in execution order.
 5. **files**: Array of 1+ objects, each with "path" (string) and "reason" (string). Every path must be a real path you confirmed exists using Glob or Read. Do NOT guess or use example paths.
 6. **complexity**: One of "low", "medium", "high"
