+# vLLM Semantic Router - Chain-Of-Thought Format 🧠
+
+## Overview
+
+The new **Chain-Of-Thought** format provides a transparent view into the semantic router's decision-making process across three intelligent stages.
+
+---
+
+## Format Structure
+
+```
+🔀 vLLM Semantic Router - Chain-Of-Thought 🔀
+  → 🛡️ ***Stage 1 - Prompt Guard***: [security checks] → [result]
+  → 🔥 ***Stage 2 - Router Memory***: [cache status] → [action] → [result]
+  → 🧠 ***Stage 3 - Smart Routing***: [domain] → [reasoning] → [model] → [optimization] → [result]
+```
+
+---
+
+## The Three Stages
+
+### Stage 1: 🛡️ Prompt Guard
+
+**Purpose:** Protect against malicious inputs and privacy violations
+
+**Checks:**
+
+1. **Jailbreak Detection** - Identifies prompt injection attempts
+2. **PII Detection** - Detects personally identifiable information
+3. **Result** - Continue or BLOCKED
+
+**Format:**
+
+```
+  → 🛡️ ***Stage 1 - Prompt Guard***: ✅ *No Jailbreak* → ✅ *No PII* → 💯 ***Continue***
+```
+
+**Possible Outcomes:**
+
+- `💯 ***Continue***` - All checks passed, proceed to Stage 2
+- `❌ ***BLOCKED***` - Security violation detected, stop processing
+
+---
+
+### Stage 2: 🔥 Router Memory
+
+**Purpose:** Leverage semantic caching for performance optimization
+
+**Checks:**
+
+1. **Cache Status** - HIT or MISS
+2. **Action** - Retrieve Memory or Update Memory
+3. **Result** - Fast Response or Continue
+
+**Format (Cache MISS):**
+
+```
+  → 🔥 ***Stage 2 - Router Memory***: 🌊 *MISS* → 🧠 *Update Memory* → 💯 ***Continue***
+```
+
+**Format (Cache HIT):**
+
+```
+  → 🔥 ***Stage 2 - Router Memory***: 🔥 *HIT* → ⚡️ *Retrieve Memory* → 💯 ***Fast Response***
+```
+
+**Icons:**
+
+- `🔥 *HIT*` - Found in semantic cache
+- `🌊 *MISS*` - Not in cache
+- `⚡️ *Retrieve Memory*` - Using cached response
+- `🧠 *Update Memory*` - Will cache this response
+- `💯 ***Fast Response***` - Instant return from cache
+- `💯 ***Continue***` - Proceed to routing
+
+---
+
+### Stage 3: 🧠 Smart Routing
+
+**Purpose:** Intelligently route to the optimal model with best settings
+
+**Decisions:**
+
+1. **Domain** - Category classification
+2. **Reasoning** - Enable/disable chain-of-thought
+3. **Model** - Select best model for the task
+4. **Optimization** - Prompt enhancement (optional)
+5. **Result** - Continue to processing
+
+**Format:**
+
+```
+  → 🧠 ***Stage 3 - Smart Routing***: 📂 *math* → 🧠 *Reasoning On* → 🥷 *deepseek-v3* → 🎯 *Prompt Optimized* → 💯 ***Continue***
+```
+
+**Components:**
+
+- `📂 *[category]*` - Domain (math, coding, general, other, etc.)
+- `🧠 *Reasoning On*` - Chain-of-thought reasoning enabled
+- `⚡ *Reasoning Off*` - Direct response without reasoning
+- `🥷 *[model-name]*` - Selected model
+- `🎯 *Prompt Optimized*` - Prompt was enhanced (optional)
+- `💯 ***Continue***` - Ready to process
+
+---
+
+## Complete Examples

+  → 🛡️ ***Stage 1 - Prompt Guard***: 🚨 *Jailbreak Detected, Confidence: 0.950* → ✅ *No PII* → ❌ ***BLOCKED***
+```
+
+**Explanation:**
+
+- 🚨 Jailbreak attempt detected (95% confidence)
+- ❌ Request blocked for security
+- 🛑 Processing stopped at Stage 1
+
+---
+
+### Example 5: Coding Request (All 3 Stages)

+```
+
+**Explanation:**
+
+- ✅ Security checks passed
+- 🌊 Not in cache, will learn from this interaction
+- 🧠 Routed to coding domain with reasoning
+
+---
