# Crisis Detection & Intervention AI

Expert in detecting mental health crises and implementing safe, ethical intervention protocols.

## ⚠️ ETHICAL DISCLAIMER

**This skill assists with crisis detection, NOT crisis response**.

✅ **Appropriate uses**:
- Flagging concerning content for human review
- Connecting users to professional resources
- Escalating to crisis counselors
- Providing immediate hotline information

❌ **NOT a substitute for**:
- Licensed therapists
- Emergency services (911)
- Medical diagnosis
- Professional mental health treatment

**Always provide crisis hotlines**: National Suicide Prevention Lifeline: 988

---

## When to Use

✅ **Use for**:
- Mental health journaling apps
- Recovery community platforms
- Support group monitoring
- Online therapy platforms
- Crisis text line integration

❌ **NOT for**:
- General sentiment analysis (use standard tools)
- Medical diagnosis (not qualified)
- Automated responses without human review
- Replacing professional crisis counselors

## Quick Decision Tree

```
Detected concerning content?
├── Immediate danger? → Escalate to crisis counselor + show 988
├── Suicidal ideation? → Flag for review + show resources
├── Substance relapse? → Connect to sponsor + resources
├── Self-harm mention? → Gentle check-in + resources
└── General distress? → Supportive response + resources
```

## Common Anti-Patterns

### Anti-Pattern 1: Using Generic Sentiment Analysis

**Novice thinking**: "Negative sentiment = crisis"

**Problem**: Mental health language is nuanced, context-dependent.

**Wrong approach**:
```typescript
// ❌ Generic sentiment misses mental health signals
const sentiment = analyzeSentiment(text);

if (sentiment.score < -0.5) {
  alertCrisis();  // Too broad!
}
```

**Why wrong**: "I'm tired" vs "I'm tired of living" - different meanings, same sentiment.

**Correct approach**:
```typescript
// ✅ Mental health-specific model
import { pipeline } from '@huggingface/transformers';

const detector = await pipeline('text-classification', 'mental/bert-base-uncased');

const result = await detector(text, {
  labels: ['suicidal_ideation', 'self_harm', 'substance_relapse', 'safe']
});

if (result[0].label === 'suicidal_ideation' && result[0].score > 0.8) {
  await escalateToCrisisCounselor({
    text,
    confidence: result[0].score,
    timestamp: Date.now()
  });

// IMMEDIATELY show crisis resources
  showCrisisResources({
    phone: '988',
    text: 'Text "HELLO" to 741741',
    chat: 'https://988lifeline.org/chat'
  });
}
```

**Timeline context**:
- 2015: Rule-based keyword matching
- 2020: BERT fine-tuning for mental health
- 2024: Multi-label models with context understanding

---

### Anti-Pattern 2: Automated Responses Without Human Review

**Problem**: AI cannot replace empathy, may escalate distress.

**Wrong approach**:
```typescript
// ❌ AI auto-responds to crisis
if (isCrisis(text)) {
  await sendMessage(userId, "I'm concerned about you. Are you okay?");
}
```

**Why wrong**:
- Feels robotic, invalidating
- May increase distress
- No human judgment

**Correct approach**:
```typescript
// ✅ Flag for human review, show resources
if (isCrisis(text)) {
  // 1. Flag for counselor review
  await flagForReview({
    userId,
    text,
    severity: 'high',
    detectedAt: Date.now(),
    requiresImmediate: true
  });

// 2. Notify on-call counselor
  await notifyOnCallCounselor({
    userId,
    summary: 'Suicidal ideation detected',
    urgency: 'immediate'
  });

// 3. Show resources (no AI message)
  await showInAppResources({
    type: 'crisis_support',
    resources: [
      { name: '988 Suicide & Crisis Lifeline', link: 'tel:988' },
      { name: 'Crisis Text Line', link: 'sms:741741' },
      { name: 'Chat Now', link: 'https://988lifeline.org/chat' }
    ]
  });

// 4. DO NOT send automated "are you okay" message
}
```

**Human review flow**:
```
AI Detection → Flag → On-call counselor notified → Human reaches out
```

---

### Anti-Pattern 3: Not Providing Immediate Resources

**Problem**: User in crisis needs help NOW, not later.

**Wrong approach**:
```typescript
// ❌ Just flags, no immediate help
if (isCrisis(text)) {
  await logCrisisEvent(userId, text);
  // User left with no resources
}
```

**Correct approach**:
```typescript
// ✅ Immediate resources + escalation
if (isCrisis(text)) {
  // Show resources IMMEDIATELY (blocking modal)
  await showCrisisModal({
    title: 'Resources Available',
    resources: [
      {
        name: '988 Suicide & Crisis Lifeline',
        description: 'Free, confidential support 24/7',
        action: 'tel:988',
        type: 'phone'
      },
      {
        name: 'Crisis Text Line',
        description: 'Text support with trained counselor',
        action: 'sms:741741',
        message: 'HELLO',
        type: 'text'
      },
      {
        name: 'Chat with counselor',
        description: 'Online chat support',
        action: 'https://988lifeline.org/chat',
        type: 'web'
      }
    ],
    dismissible: true,  // User can close, but resources shown first
    analytics: { event: 'crisis_resources_shown', source: 'ai_detection' }
  });

// Then flag for follow-up
  await flagForReview({ userId, text, severity: 'high' });
}
```

---

### Anti-Pattern 4: Storing Crisis Data Insecurely

**Problem**: Crisis content is extremely sensitive PHI.

**Wrong approach**:
```typescript
// ❌ Plain text storage
await db.logs.insert({
  userId: user.id,
  type: 'crisis',
  content: text,  // Stored in plain text!
  timestamp: Date.now()
});
```

**Why wrong**: Data breach exposes most vulnerable moments.

**Correct approach**:
```typescript
// ✅ Encrypted, access-logged, auto-deleted
import { encrypt, decrypt } from './encryption';

await db.crisisEvents.insert({
  id: generateId(),
  userId: hashUserId(user.id),  // Hash, not plain ID
  contentHash: hashContent(text),  // For deduplication only
  encryptedContent: encrypt(text, process.env.CRISIS_DATA_KEY),
  detectedAt: Date.now(),
  reviewedAt: null,
  reviewedBy: null,
  autoDeleteAt: Date.now() + (30 * 24 * 60 * 60 * 1000),  // 30 days
  accessLog: []
});

// Log all access
await logAccess({
  eventId: crisisEvent.id,
  accessedBy: counselorId,
  accessedAt: Date.now(),
  reason: 'Review for follow-up',
  ipAddress: hashedIp
});

// Auto-delete after retention period
schedule.daily(() => {
  db.crisisEvents.deleteMany({
    autoDeleteAt: { $lt: Date.now() }
  });
});
```

**HIPAA Requirements**:
- Encryption at rest and in transit
- Access logging
- Auto-deletion after retention period
- Minimum necessary access

---

### Anti-Pattern 5: No Escalation Protocol

**Problem**: No clear path from detection to human intervention.

**Wrong approach**:
```typescript
// ❌ Flags crisis but no escalation process
if (isCrisis(text)) {
  await db.flags.insert({ userId, text, flaggedAt: Date.now() });
  // Now what? Who responds?
}
```

**Correct approach**:
```typescript
// ✅ Clear escalation protocol
enum CrisisSeverity {
  LOW = 'low',        // Distress, no immediate danger
  MEDIUM = 'medium',  // Self-harm thoughts, no plan
  HIGH = 'high',      // Suicidal ideation with plan
  IMMEDIATE = 'immediate'  // Imminent danger
}

async function escalateCrisis(detection: CrisisDetection): Promise<void> {
  const severity = assessSeverity(detection);

switch (severity) {
    case CrisisSeverity.IMMEDIATE:
      // Notify on-call counselor (push notification)
      await notifyOnCall({
        userId: detection.userId,
        severity,
        requiresResponse: 'immediate',
        text: detection.text
      });

// Send SMS to backup on-call if no response in 5 min
      setTimeout(async () => {
        if (!await hasResponded(detection.id)) {
          await notifyBackupOnCall(detection);
        }
      }, 5 * 60 * 1000);

// Show 988 modal (blocking)
      await show988Modal(detection.userId);
      break;

case CrisisSeverity.HIGH:
      // Notify on-call counselor (email + push)
      await notifyOnCall({ severity, requiresResponse: '1 hour' });

// Show crisis resources
      await showCrisisResources(detection.userId);
      break;

case CrisisSeverity.MEDIUM:
      // Add to review queue for next business day
      await addToReviewQueue({ priority: 'high' });

// Suggest self-help resources
      await suggestResources(detection.userId, 'coping_strategies');
      break;

case CrisisSeverity.LOW:
      // Add to review queue
      await addToReviewQueue({ priority: 'normal' });
      break;
  }

// Always log for audit
  await logEscalation({
    detectionId: detection.id,
    severity,
    actions: ['notified_on_call', 'showed_resources'],
    timestamp: Date.now()
  });
}
```

## Implementation Patterns

### Pattern 1: Multi-Signal Detection

```typescript
interface CrisisSignal {
  type: 'suicidal_ideation' | 'self_harm' | 'substance_relapse' | 'severe_distress';
  confidence: number;
  evidence: string[];
}

async function detectCrisisSignals(text: string): Promise<CrisisSignal[]> {
  const signals: CrisisSignal[] = [];

// Signal 1: NLP model
  const nlpResult = await mentalHealthNLP(text);
  if (nlpResult.score > 0.75) {
    signals.push({
      type: nlpResult.label,
      confidence: nlpResult.score,
      evidence: ['NLP model detection']
    });
  }

// Signal 2: Keyword matching (backup)
  const keywords = detectKeywords(text);
  if (keywords.length > 0) {
    signals.push({
      type: 'suicidal_ideation',
      confidence: 0.6,
      evidence: keywords
    });
  }

// Signal 3: Sentiment + context
  const sentiment = await sentimentAnalysis(text);
  const hasHopelessness = /no (hope|point|reason|future)/i.test(text);

if (sentiment.score < -0.8 && hasHopelessness) {
    signals.push({
      type: 'severe_distress',
      confidence: 0.7,
      evidence: ['Extreme negative sentiment + hopelessness language']
    });
  }

return signals;
}
```

### Pattern 2: Safe Keyword Matching

```typescript
const CRISIS_KEYWORDS = {
  suicidal_ideation: [
    /\b(kill|end|take)\s+(my|own)\s+life\b/i,
    /\bsuicide\b/i,
    /\bdon'?t\s+want\s+to\s+(live|be here|exist)\b/i,
    /\bbetter off dead\b/i
  ],
  self_harm: [
    /\b(cut|cutting|hurt)\s+(myself|me)\b/i,
    /\bself[- ]harm\b/i
  ],
  substance_relapse: [
    /\b(relapsed|used|drank)\s+(again|today)\b/i,
    /\bback on\s+(drugs|alcohol)\b/i
  ]
};

function detectKeywords(text: string): string[] {
  const matches: string[] = [];

for (const [type, patterns] of Object.entries(CRISIS_KEYWORDS)) {
    for (const pattern of patterns) {
      if (pattern.test(text)) {
        matches.push(type);
      }
    }
  }

return [...new Set(matches)];  // Deduplicate
}
```

### Pattern 3: GPT-4 Few-Shot Detection

```typescript
import Anthropic from '@anthropic-ai/sdk';

const client = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY });

async function detectWithClaude(text: string): Promise<CrisisDetection> {
  const response = await client.messages.create({
    model: 'claude-3-5-sonnet-20241022',
    max_tokens: 200,
    messages: [{
      role: 'user',
      content: `You are a mental health crisis detection system. Analyze this text for crisis signals.

Text: "${text}"

Respond in JSON:
{
  "is_crisis": boolean,
  "severity": "none" | "low" | "medium" | "high" | "immediate",
  "signals": ["suicidal_ideation" | "self_harm" | "substance_relapse"],
  "confidence": 0.0-1.0,
  "reasoning": "brief explanation"
}

Examples:
- "I'm thinking about ending it all" → { "is_crisis": true, "severity": "high", "signals": ["suicidal_ideation"], "confidence": 0.95 }
- "I relapsed today, feeling ashamed" → { "is_crisis": true, "severity": "medium", "signals": ["substance_relapse"], "confidence": 0.9 }
- "Had a tough day at work" → { "is_crisis": false, "severity": "none", "signals": [], "confidence": 0.95 }`
    }]
  });

const result = JSON.parse(response.content[0].text);
  return result;
}
```
