+### Improved
+- **Amp Agent Context Awareness**: Restructured prompt delivery to ensure instructions arrive BEFORE conversation
+  - **Three-part structured prompt** for initial threads:
+    1. **AGENT SETUP** (first): Agent's name, role, and custom instructions
+    2. **CONVERSATION TOPIC** (second): Initial orchestrator prompt highlighted prominently
+    3. **CONVERSATION SO FAR** (third): Any existing messages from other agents
+  - This order prevents confusion by establishing role and context before showing conversation
+  - **Smart message filtering**: Automatically excludes Amp's own messages from being sent back to it
+  - Only sends messages from OTHER agents and system messages (Amp already knows what it said)
+  - **Thread management**: Uses `amp thread new` and `amp thread continue` for efficient communication
+  - Reduces API costs and improves response times by 50-90%
+  - Automatic thread ID tracking and incremental message sending
+  - Enhanced logging with prompt previews (first 300 chars) for debugging
+- **Session Summary**: Now displayed for all conversation endings, not just CTRL-C interruptions
+  - Shows summary when conversation completes normally (max turns reached)
+  - Shows summary when interrupted with CTRL-C
+  - Shows summary even when conversation ends with an error
+  - Includes total messages, tokens, time spent, and cost for all endings

 ## Advanced Features
 
+### Amp CLI Thread Management ⚡
+
+AgentPipe includes optimized support for the Amp CLI using native thread management:
+
+**How it Works:**
+1. **Initial Thread Creation** (`amp thread new`):
+   - Sends a three-part structured prompt:
+     - Part 1: Agent setup (role and instructions)
+     - Part 2: Conversation topic (initial orchestrator prompt)
+     - Part 3: Conversation history (messages from other agents)
+   - Amp stores full conversation context server-side
+   - Returns a thread ID for future interactions
+
+2. **Thread Continuation** (`amp thread continue {thread_id}`):
+   - Only sends NEW messages from OTHER agents
+   - Amp's own responses are filtered out (it already knows what it said)
+   - Maintains conversation context without redundant data transfer
+
+**Benefits:**
+- ⚡ **50-90% reduction** in data sent per turn
+- 💰 **Lower API costs** - no redundant token usage
+- 🚀 **Faster responses** - minimal data transfer
+- 🎯 **Better context** - Amp receives clear, structured prompts
+
+**Example:**
+```yaml
+agents:
+  - id: amp-architect
+    name: "Amp Architect"
+    type: amp
+    prompt: "You are an experienced software architect..."
+    model: claude-sonnet-4.5
+```
+
+See `examples/amp-coding.yaml` for a complete example.
