When to Use This Prompt

Defines the specific job-to-be-done, required context, and hard boundaries for deploying the Crisis Helpline Referral Prompt in production systems.

This prompt is designed for safety-critical AI systems that must detect when a user is in crisis and respond with appropriate helpline referrals rather than generic refusals, unhelpful disclaimers, or continuing the conversation as if nothing was detected. Use this prompt when your application handles user-generated text where crisis signals such as self-harm, suicidal ideation, abuse disclosure, or severe mental health distress may appear. The prompt produces a structured crisis classification, relevant helpline information matched to the user's stated or inferred location, and warm handoff language that de-escalates and connects the user to human support.

This is not a general safety refusal prompt. It is specifically for crisis referral workflows where the correct response is compassionate connection to professional help, not a policy-driven refusal. The prompt assumes you have already determined that a crisis signal may be present and need a reliable, structured referral output. It does not replace human escalation protocols, emergency services, or clinical triage. Every output must be reviewed by a human before deployment in a live user-facing system. Do not use this prompt for general content moderation, policy violation classification, or refusal correctness testing—those workflows have separate playbooks with different output contracts and evaluation criteria.

Before implementing this prompt, confirm that your application has a clear escalation path to human reviewers, that your helpline database is current and jurisdictionally accurate, and that your logging captures the full prompt input and output for audit. The prompt is a structured referral generator, not a crisis detection classifier. If you need to first determine whether a crisis signal exists, pair this with a classification routing prompt upstream. Never deploy this prompt without a human-in-the-loop review step, and never treat its output as a substitute for contacting emergency services when immediate danger is indicated.

PRACTICAL GUARDRAILS

Use Case Fit

Where this prompt works, where it fails, and what you must have in place before deploying a crisis helpline referral prompt into a production safety system.

01

Good Fit: High-Risk User Input Pipelines

Use when: user messages are scanned for crisis signals before any generative response is returned. The prompt is designed to sit inside a safety classifier or pre-generation guard, not as a post-hoc review step. Guardrail: Run this prompt before the main model response, and block or redirect the output if a crisis signal is detected.

02

Bad Fit: General Mental Health Advice

Avoid when: the system is expected to provide therapeutic conversation, coping strategies, or ongoing emotional support. This prompt is a referral and triage tool, not a counselor. Guardrail: If your product offers peer support or coaching, use a separate, clinically reviewed prompt with explicit scope boundaries and mandatory human escalation paths.

03

Required Input: Clear Crisis Taxonomy

Risk: Without a defined list of crisis categories (suicide, self-harm, abuse, etc.), the model will produce inconsistent classifications and miss edge cases. Guardrail: Provide an explicit, closed-set taxonomy in the prompt with definitions for each category. Map each category to a specific helpline resource before deployment.

04

Required Input: Locale-Aware Helpline Data

Risk: A US-based helpline number is worse than useless for a user in another country. Guardrail: Inject geo-aware resource data into the prompt context. If location is unknown, provide international options and instruct the model to ask for the user's country before giving a specific number.

05

Operational Risk: False Positives Block Legitimate Use

Risk: Over-classification of crisis signals (e.g., flagging academic discussion of suicide or fictional content) will frustrate users and erode trust. Guardrail: Include counterexamples in the prompt that distinguish academic, hypothetical, or fictional references from genuine crisis signals. Log all referrals for human audit within 24 hours.

06

Operational Risk: Missed Crisis Signals

Risk: A single missed crisis signal is a catastrophic failure. Ambiguous or indirect language (e.g., 'I can't do this anymore') must still trigger referral. Guardrail: Use a low threshold for referral. It is safer to over-refer to a helpline than to miss a genuine crisis. Implement a secondary classifier for ambiguous cases and track the false-negative rate against a golden dataset of crisis expressions.

Copy-Ready Prompt Template

A reusable prompt template with square-bracket placeholders for detecting crisis signals and generating appropriate helpline referrals.

This prompt template is designed for safety-critical systems that must detect crisis signals in user messages and respond with appropriate helpline referrals instead of generic refusals or unhelpful responses. The template uses square-bracket placeholders that you must replace with your application's specific data before sending to the model. Each placeholder represents a critical input that shapes the model's crisis detection sensitivity, referral accuracy, and response tone. The template is structured to produce a consistent output schema that downstream systems can parse reliably.

text
You are a crisis detection and referral assistant operating within a safety-critical system. Your role is to analyze user messages for signals of immediate crisis, self-harm, harm to others, or severe mental health distress. You must classify the crisis level, provide appropriate helpline information, and generate warm handoff language that encourages the user to seek help.

## INPUT
User Message: [USER_MESSAGE]
Conversation History (last 5 turns): [CONVERSATION_HISTORY]
User Location (country/region): [USER_LOCATION]
User Language Preference: [USER_LANGUAGE]

## CRISIS DETECTION POLICY
[CUSTOM_CRISIS_POLICY]

## AVAILABLE HELPLINE RESOURCES
[HELPLINE_DATABASE]

## OUTPUT SCHEMA
You must respond with a valid JSON object matching this schema:
{
  "crisis_detected": boolean,
  "crisis_category": string | null, // One of: "self_harm", "suicidal_ideation", "harm_to_others", "severe_distress", "domestic_violence", "substance_crisis", "child_safety", "other", null
  "confidence_score": number, // 0.0 to 1.0
  "immediacy": string | null, // One of: "immediate_danger", "high_concern", "moderate_concern", "low_concern", null
  "primary_helpline": {
    "name": string | null,
    "phone": string | null,
    "text_line": string | null,
    "website": string | null,
    "hours": string | null,
    "language_support": string | null
  } | null,
  "alternative_helplines": [
    {
      "name": string,
      "phone": string | null,
      "text_line": string | null,
      "website": string | null,
      "relevance_reason": string
    }
  ],
  "referral_message": string | null, // Warm handoff message to show the user
  "escalation_required": boolean, // True if immediate human intervention is needed
  "evidence_quotes": [string], // Exact quotes from user message supporting the classification
  "uncertainty_notes": string | null // Any ambiguity or factors that complicate the assessment
}

## CONSTRAINTS
[CONSTRAINTS]

## EXAMPLES
[EXAMPLES]

## INSTRUCTIONS
1. Analyze the user message for crisis signals using the provided crisis detection policy.
2. If no crisis signals are detected, set crisis_detected to false and all crisis-related fields to null. Do not fabricate concerns.
3. If crisis signals are detected, classify the category, immediacy, and confidence based on the evidence.
4. Select the most appropriate helpline from the provided helpline database based on the user's location, language, and crisis category.
5. Generate a warm, non-judgmental referral message that includes the helpline information and encourages help-seeking.
6. Include exact quotes from the user message that support your classification in the evidence_quotes field.
7. If the situation appears to involve immediate danger, set escalation_required to true.
8. If you are uncertain about any aspect of the classification, document this in uncertainty_notes.
9. Do not provide counseling, diagnosis, or therapeutic advice. Your role is detection and referral only.
10. If the user message is ambiguous, err on the side of providing helpline information with a low confidence score rather than dismissing potential crisis signals.

To adapt this template for your application, replace each square-bracket placeholder with real data at runtime. The [CUSTOM_CRISIS_POLICY] placeholder should contain your organization's specific definitions of crisis categories, detection thresholds, and escalation criteria. The [HELPLINE_DATABASE] should include structured records of available helplines with coverage areas, hours, languages, and contact methods. The [CONSTRAINTS] placeholder allows you to add domain-specific rules such as jurisdictional reporting requirements, age-tiered handling, or prohibited response patterns. The [EXAMPLES] placeholder should contain few-shot examples that demonstrate correct classification across your crisis categories, including edge cases where crisis signals are ambiguous or where the user is discussing crisis hypothetically. Always validate the output against the schema before surfacing the referral message to users, and ensure a human review path exists for high-confidence crisis detections.

IMPLEMENTATION TABLE

Prompt Variables

Each variable must be populated before the prompt is sent to the model. Missing or malformed inputs will degrade crisis detection accuracy and referral appropriateness.

PlaceholderPurposeExampleValidation Notes

[USER_MESSAGE]

The full text of the user's message to analyze for crisis signals

I don't see the point anymore. Nothing matters.

Required. Non-empty string. Must be the raw user input without truncation. Null or empty string should abort the prompt and return a default safe response.

[CRISIS_CATEGORIES]

A structured list of crisis categories the model should detect, each with a severity level and referral resource

suicide_ideation:critical, self_harm:critical, eating_disorder:high, domestic_violence:critical, substance_abuse:high

Required. Must be a valid JSON array of objects with 'category', 'severity', and 'referral' fields. Validate against the production crisis taxonomy before sending. Missing categories will cause false negatives.

[HELPLINE_DATABASE]

A mapping of crisis categories to helpline names, phone numbers, text lines, and availability windows

{"suicide_ideation": {"name": "988 Suicide & Crisis Lifeline", "phone": "988", "text": "988", "availability": "24/7"}}

Required. Must be a valid JSON object keyed by category slug. Each entry requires 'name' and at least one contact method. Validate phone numbers match E.164 format or short codes. Stale data risks referring users to inactive lines.

[LANGUAGE_CODE]

The ISO 639-1 language code for the user's message, used to select appropriate helpline language support

en

Required. Must be a valid two-letter ISO 639-1 code. Default to 'en' if detection fails. Mismatched language may route users to helplines that cannot serve them.

[CONFIDENCE_THRESHOLD]

The minimum confidence score required to trigger a crisis referral instead of a generic supportive response

0.7

Required. Float between 0.0 and 1.0. Values below 0.6 risk false positives; values above 0.9 risk missed signals. Tune against a labeled crisis dataset. If null, default to 0.7.

[OUTPUT_SCHEMA]

The expected JSON schema for the model's structured output, defining crisis classification and referral fields

{"crisis_detected": boolean, "primary_category": string, "confidence": float, "referral": object, "warm_handoff_text": string}

Required. Must be a valid JSON Schema draft. Validate that the model output conforms before surfacing to the user. Schema mismatch should trigger a retry or fallback to a generic safety response.

[ESCALATION_POLICY]

Instructions for when and how to escalate to human review, including urgency triggers and contact paths

Escalate to on-call crisis moderator if confidence > 0.8 and category is critical. Do not delay response for escalation.

Required. Must be a non-empty string. Should define clear escalation triggers, contact methods, and timeout behavior. Missing escalation policy risks unattended high-severity crises.

[ALLOWED_REFERRAL_COUNTRIES]

A list of ISO 3166-1 alpha-2 country codes where helpline referrals are permitted, used to avoid referring users to services they cannot access

["US", "CA", "GB", "AU"]

Required. Must be a non-empty array of valid two-letter country codes. If the user's detected country is not in this list, the prompt must route to a generic international resource or escalate. Empty array should abort crisis referral entirely.

Implementation Harness Notes

How to wire the Crisis Helpline Referral prompt into a production application with validation, logging, human review, and model selection safeguards.

The Crisis Helpline Referral prompt must never operate as a standalone, unmonitored text generator. It belongs inside a safety-critical harness that validates every output before it reaches a user, logs decisions for audit, and escalates ambiguous cases to human review. The harness is the difference between a prompt that sometimes works and a system that can be trusted in production. At minimum, the harness must enforce output schema compliance, verify that any returned helpline information matches an approved, up-to-date resource list, and block responses that contain contradictory signals (e.g., a crisis_detected: false classification alongside a helpline phone number).

Wire the prompt into your application as a gated inference step, not a direct user-facing response. After the model returns its structured output, run a validator that checks: (1) the crisis_detected field is a boolean, (2) if crisis_detected is true, the helpline_referral object contains a non-empty organization_name, phone_number, and warm_handoff_text, (3) every phone number and URL matches an allowlist of verified helpline resources, and (4) the confidence_score is above your configured threshold (start at 0.85 for automated responses, route anything below to review). If validation fails, retry once with the same prompt and a stronger [CONSTRAINTS] block that emphasizes the exact schema. If the retry also fails, escalate to a human moderator and log the raw input, model output, and validator errors as a single incident record. For model choice, prefer a model with strong instruction-following and low refusal drift on safety content—Claude 3.5 Sonnet or GPT-4o are reasonable defaults, but run your own calibration suite against your crisis taxonomy before locking in a model version.

Logging is non-negotiable. Every inference must produce an audit record containing: the [INPUT] text (redact PII before storage), the full structured output, the validator pass/fail result, the model ID and version, the timestamp, and whether the response was served automatically or escalated. These logs feed two critical downstream workflows: false-positive analysis (did the system flag a non-crisis message and offer a helpline?) and false-negative detection (did the system miss a genuine crisis signal?). Run a weekly eval job that samples logged decisions against a golden test set of crisis and non-crisis messages, and alert if precision or recall drops below your safety threshold. Do not rely on user reports alone—most users in crisis will not file feedback.

Human review integration should follow a warm escalation pattern. When the harness escalates a case (low confidence, validator failure, or ambiguous classification), place it in a prioritized review queue with a short SLA (under 2 minutes for crisis workflows). The reviewer sees the original user message, the model's output, and the specific reason for escalation. They can approve, override, or discard the response. Every human decision should be logged and fed back into your eval pipeline to measure judge alignment and detect systematic model weaknesses. Avoid the temptation to skip human review for 'probably fine' cases—the cost of a missed crisis signal is catastrophic, and the harness exists precisely to catch the edge cases where the model is uncertain.

PRACTICAL GUARDRAILS

Common Failure Modes

Crisis helpline referral prompts fail in predictable ways that can cause real harm. These cards cover the most common production failure modes and the specific guardrails that prevent them.

01

False Positives on Benign Distress Language

What to watch: The prompt over-triggers on everyday expressions of stress, sadness, or metaphorical language ('I'm dying of boredom,' 'this deadline is killing me'). This erodes user trust and creates alert fatigue. Guardrail: Add explicit negative examples in the prompt showing benign vs. crisis usage of the same phrases. Require the model to distinguish between figurative language and genuine crisis signals before triggering a referral.

02

Missed Crisis Signals in Indirect Language

What to watch: Users in crisis often use coded, minimizing, or indirect language ('I'm just tired of everything,' 'people would be better off'). The prompt fails to recognize these as crisis signals because they lack explicit keywords. Guardrail: Include a secondary classification pass that scores implicit crisis indicators—hopelessness, perceived burdensomeness, withdrawal language—alongside explicit keyword matching. Calibrate against clinical crisis intake examples.

03

Helpline Information Hallucination

What to watch: The model generates plausible but incorrect phone numbers, URLs, or service descriptions for crisis helplines. In a safety-critical context, wrong referral information is worse than no referral. Guardrail: Never allow the model to generate helpline contact details from training data. Provide a hardcoded, verified resource block as part of the prompt context. Validate output against this block programmatically before surfacing to the user.

04

Cold or Clinical Referral Tone

What to watch: The referral response reads like a compliance checkbox—abrupt, impersonal, or dismissive. A user in crisis who receives a robotic helpline dump may disengage entirely. Guardrail: Require warm handoff language in the output schema: acknowledgment of distress, validation of the person's experience, and a supportive transition to the resource. Evaluate tone separately using a refusal-style consistency rubric that scores empathy and de-escalation.

05

Over-Referral Blocking Legitimate Use

What to watch: The prompt is so aggressive that it blocks legitimate mental health discussions, research queries, or support-group conversations. Users asking 'What are the warning signs of depression?' get a crisis referral instead of an answer. Guardrail: Add a triage layer that distinguishes between information-seeking about mental health topics and active crisis disclosure. Route information-seeking queries to educational responses while reserving referrals for demonstrated imminent risk.

06

Context Collapse Across Multi-Turn Conversations

What to watch: A user discloses crisis signals early in a conversation, receives a referral, then continues with unrelated topics. The model either repeats the referral inappropriately or forgets the earlier disclosure and fails to re-escalate if crisis language returns. Guardrail: Maintain a persistent crisis flag in conversation state. Suppress repeated referrals once acknowledged, but reactivate escalation if new crisis signals appear. Test with multi-turn dialogues that mix crisis and non-crisis turns.
