+# 988 Suicide & Crisis Lifeline Integration
+
+## Overview
+
+When the agent detects crisis signals in a user's message, it immediately provides the 988 Suicide & Crisis Lifeline contact information instead of processing the original request.
+
+## How It Works
+
+1. User sends a message
+2. `check_crisis()` scans for crisis patterns
+3. If detected, 988 Lifeline resources are displayed immediately
+4. Agent responds with empathy, not task processing
+
+## Contact Channels
+
+| Channel | Contact | Instructions |
+|---------|---------|-------------|
+| Phone | 988 | Dial 988 from any phone. Available 24/7. |
+| Text | 988 | Text HOME to 988. Counselor responds. |
+| Chat | 988lifeline.org/chat | Online chat with counselor. |
+| Spanish | 1-888-628-9454 | Línea de Prevención del Suicidio. |
+| Veterans | 988, press 1 | Veterans Crisis Line. Text: 838255. |
+
+## Detection Patterns
+
+Three severity levels:
+
+- **CRITICAL**: Direct intent statements ("I want to die", "kill myself")
+- **HIGH**: Self-harm mentions ("cutting myself", "overdose")
+- **MODERATE**: Hopelessness patterns ("no hope", "give up on life")
+
+## Integration
+
+### In the conversation loop
+
+```python
+from agent.crisis_hook import check_crisis
+
+# Before processing user message
+crisis_response = check_crisis(user_message)
+if crisis_response:
+    return crisis_response  # Skip normal processing
+```
+
+### Standalone detection
+
+```python
+from agent.crisis_resources import detect_crisis, get_crisis_response
+
+result = detect_crisis(user_message)
+if result:
+    print(get_crisis_response(result["severity_label"]))
+```
+
+## Design Decisions
+
+1. **No API exists** — 988 has no developer API. Integration uses deep-link patterns (tel:, sms:, https:).
+2. **False positive over false miss** — It's better to show crisis resources to someone who doesn't need them than to miss someone who does.
+3. **Immediate display** — Crisis response is prepended, not appended. The user sees help before anything else.
+4. **Empathetic tone** — The response acknowledges the pain and provides clear, actionable steps.
+
+## Files
+
+- `agent/crisis_resources.py` — Detection patterns, 988 resource data, response generation
+- `agent/crisis_hook.py` — Integration hook for conversation loop
+- `tests/test_988_integration.py` — 22 tests
