+# 📋 Implementation Plan: "Agent Social Stream" Redesign
+
+### ## Approach
+We will transform the interface into a **Social Feed for Agent Activity**. The core metaphor is "watching the agents work" rather than "managing a list". The aesthetic is **Earthy Elegant**—dark, warm, soft, and high-polish.
+
+**Concept:** "The Living Stream"
+- **Metaphor:** Twitter/Instagram for code.
+- **Visuals:** Soft `rounded-3xl` cards, floating depth, warm dark gradient background.
+- **Interaction:** Scroll the feed, click to expand details (like opening a thread).
+
+### ## Visual Language
+- **Background:** `bg-[linear-gradient(to_bottom_right,#2D2D2D,#363636)]` (Warm Earthy Gradient).
+- **Cards:** `bg-[#363636]`, `rounded-3xl`, `shadow-2xl`, `hover:scale-[1.01]`.
+- **Typography:** Friendly sans-serif headers. Monospace IDs.
+- **Dependencies:** Soft "Pills" or "Hashtags" (`rounded-full`, pastel tints).
+
+### ## Steps
+
+1. **Refine Tokens (10 min)**
+   - Add "Soft Shadow" tokens to `globals.css` (`shadow-[0_8px_30px_rgba(0,0,0,0.12)]`).
+   - Add "Earthy Gradient" utility.
+
+2. **Redesign `SocialCard` as "The Post" (20 min)**
+   - **Header:** Large Agent Avatar + Name (Left aligned). "Posted" time (Last Activity).
+   - **Body:** Task ID (small, muted) -> Task Title (Large, 1.1rem).
+   - **Tags:** Dependency bubbles (`bg-rose-500/10 text-rose-200`) designed like hashtags/pills.
+   - **Footer:** Action icons (Chat, Graph, Kanban) styled like social actions (heart/comment/share).
+
+3.  **Redesign `SocialPage` as "The Feed" (15 min)**
+    *   **Layout:** A centered feed container (max-width `42rem` / `672px` for optimal reading).
+    *   **Scroll:** Smooth vertical scrolling.
+    *   **Background:** Warm dark gradient.
+
+### ## Timeline
+| Phase | Duration |
+|-------|----------|
+| Refine Tokens | 10 min |
+| `SocialCard` Redesign | 20 min |
+| `SocialPage` Feed | 15 min |
