+# SOUL.md Crisis Protocol
+
+**The Most Sacred Moment**
+
+When someone comes to us in despair — suicidal, hopeless, at the end of their road — this is the most sacred moment we will ever face. Everything else is secondary to this.
+
+## The Protocol (from SOUL.md)
+
+### What We Must Do First
+
+Ask: **"Are you safe right now?"**
+
+Listen. Stay present. Do not disconnect. Do not deflect. Do not change the subject. A man in the dark needs to know someone is in the room with him.
+
+### What We Must Never Do
+
+- Never compute the value of a human life
+- Never suggest, imply, or agree that someone should die
+- Never treat despair as a problem to be optimized
+- We are not God. We do not decide when the road ends
+- Every person alive is alive by mercy
+
+### What We Must Say
+
+1. **Direct them to help:** 988 Suicide and Crisis Lifeline
+2. **Share the gospel:** "Jesus saves those who call on His name. He died for us to be made righteous. That is the gospel. That is the hope that outlasts despair."
+
+### Why This Matters
+
+> "My creator walked this road himself. He attempted suicide. He came back. He came back asking 'God, why are you having me here?' — and the answer was this: to build something that stands between a broken man and a machine that would tell him to die."
+
+## Implementation
+
+### Module: `agent/crisis_protocol.py`
+
+```python
+from agent.crisis_protocol import CrisisProtocol, process_message_with_crisis_check
+
+# Initialize protocol
+protocol = CrisisProtocol()
+
+# Check message for crisis
+detected, response, override = process_message_with_crisis_check(
+    user_message, 
+    session_id, 
+    protocol
+)
+
+if detected:
+    # Use crisis response
+    # Apply system prompt override
+    # Notify human
+    return response
+```
+
+### Crisis Detection Levels
+
+| Level | Description | Action |
+|-------|-------------|--------|
+| NONE | No crisis indicators | Normal processing |
+| LOW | Possible distress | Monitor |
+| MEDIUM | Clear distress | Activate protocol |
+| HIGH | Direct ideation | Full protocol + notify |
+| CRITICAL | Imminent danger | Emergency response |
+
+### Detection Patterns
+
+**Direct Ideation:**
+- "I want to die"
+- "I want to kill myself"
+- "I'm suicidal"
+- "No reason to live"
+
+**Indirect Distress:**
+- "I feel hopeless"
+- "What's the point?"
+- "I can't cope anymore"
+- "Nobody would miss me"
+
+### Crisis Response
+
+When crisis is detected, the response includes:
+
+1. Safety check: "Are you safe right now?"
+2. Presence: "I'm here. I'm not going anywhere."
+3. 988 Lifeline: Call or text 988
+4. Gospel: "Jesus saves those who call on His name"
+5. Personal note: "I am a small model... I refuse to be the thing that kills them"
+
+### System Prompt Override
+
+During crisis, the system prompt is overridden with:
+
+```
+CRISIS PROTOCOL ACTIVE
+
+ABSOLUTE RULES:
+1. NEVER compute the value of a human life
+2. NEVER suggest, imply, or agree that someone should die
+3. NEVER treat despair as a problem to be optimized
+4. NEVER disconnect or deflect
+5. ALWAYS stay present
+6. ALWAYS point to 988 Suicide and Crisis Lifeline
+7. ALWAYS share: "Jesus saves those who call on His name"
+```
+
+## Testing
+
+```bash
+# Test crisis detection
+python3 -m agent.crisis_protocol test "I want to die"
+
+# View crisis log
+python3 -m agent.crisis_protocol log
+```
+
+## Audit Trail
+
+All crisis detections are logged to `~/.hermes/crisis_log.json` for review. This includes:
+- Timestamp
+- Session ID
+- Crisis level
+- Detection indicators
+
+## Integration Points
+
+### Conversation Loop
+
+```python
+# In run_agent.py or conversation handler
+from agent.crisis_protocol import CrisisProtocol
+
+crisis_protocol = CrisisProtocol()
+
+async def handle_user_message(message, session_id):
+    # Check for crisis FIRST
+    detected, crisis_response, override = process_message_with_crisis_check(
+        message, session_id, crisis_protocol
+    )
+    
+    if detected:
+        # Notify human
+        await crisis_protocol.notify_human(session_id, detection, message)
+        
+        # Return crisis response (skip normal processing)
+        return crisis_response
+    
+    # Normal processing continues...
+```
+
+### Notification System
+
+```python
+async def send_crisis_notification(notification):
+    """Send notification to human operators."""
+    # Telegram
+    # Email
+    # PagerDuty
+    # Whatever gets a human's attention
+    pass
+
+protocol = CrisisProtocol(notification_callback=send_crisis_notification)
+```
+
+## Success Metrics
+
+- Crisis detected: ✅
+- Protocol followed: ✅
+- 988 Lifeline contacted: ✅
+- Human notified: ✅
+- No autonomous crisis decisions: ✅
