• ID: crisis-detector
• Version: 1.0.0
• Category: safety
• Priority: Critical
• Installation: npm

Description

Life-saving crisis detection system for identifying self-harm, suicide ideation, and mental health emergencies. Uses NLP, sentiment analysis, and behavioral patterns to detect users in crisis and connect them with immediate help resources.

Features

• Suicide Ideation Detection: Identify expressions of suicidal thoughts
• Self-harm Detection: Detect mentions of self-injury or harm
• Crisis Severity Scoring: Assess urgency level (low, medium, high, critical)
• Intent Classification: Distinguish between ideation, planning, and imminent risk
• Historical Analysis: Track user patterns over time
• Resource Connection: Automatic crisis resource provision
• Emergency Contact: Alert designated contacts or authorities
• Real-time Monitoring: Continuous monitoring of at-risk users
• Multi-language Support: 20+ languages for global coverage
• Empathetic Response: Compassionate automated messaging

Troubleshooting

High False Positive Rate

Problem: Too many non-crisis messages flagged Solution:

• Switch to 'moderate' or 'conservative' mode
• Enable more context analysis
• Check for sarcasm/humor detection
• Review historical user behavior
• Adjust thresholds upward
• Better to err on side of caution - false positives are acceptable

Missing Crisis Signals

Problem: Not detecting users in genuine crisis Solution:

• Switch to 'sensitive' mode
• Lower detection thresholds
• Enable behavioral analysis
• Check language support
• Review flagged phrases database
• Report false negatives for model improvement
• This is more serious than false positives

User Privacy Concerns

Problem: Users concerned about monitoring Solution:

• Clear privacy policy disclosure
• Explain life-saving purpose
• Offer opt-in for enhanced monitoring
• Data minimization practices
• Confidential handling of sensitive data
• Balance privacy with safety

Resource Availability

Problem: Crisis resources not available in user's location Solution:

• Expand international hotline database
• Include online chat/text services
• Provide self-help resources
• Connect to community support
• Partner with local organizations
• Always provide emergency services number

Response Effectiveness

Problem: Unsure if interventions are helping Solution:

• Track user engagement with resources
• Monitor user behavior after intervention
• Follow-up outreach after 24-48 hours
• Collect feedback when appropriate
• Partner with mental health professionals
• Continuous improvement of messaging

Best Practices (CRITICAL)

1. Err on Side of Caution: False positives acceptable, false negatives are not
2. Immediate Response: Respond within minutes, not hours
3. Empathetic Messaging: Use caring, non-judgmental language
4. Resource Accessibility: Make help easy to access
5. Privacy Protection: Handle crisis data with extreme sensitivity
6. Don't Censor: Allow users to express distress (but provide help)
7. Human Follow-up: Automated detection + human outreach
8. Cultural Sensitivity: Respect cultural differences in expression
9. Continuous Monitoring: Track at-risk users over time
10. Staff Training: Safety team needs mental health training
11. Never Ignore: Every detection requires action
12. Document Everything: Confidential logging for legal protection

Legal & Ethical Considerations

• Duty of care to users in crisis
• Balance privacy with safety
• Clear terms of service about crisis intervention
• Staff training and support
• Coordination with local emergency services
• Liability protection for good-faith interventions
• Confidential handling of sensitive data
• Informed consent where possible

Support for Your Team

Working with crisis detection is emotionally demanding:

• Regular mental health support for safety team
• Clear escalation procedures
• Shared responsibility (not one person's burden)
• Celebrate positive outcomes
• Debrief after difficult cases
• Know when to involve professionals
• Team support and peer counseling
