# validate_cancel_intent

Detects cancellation intent — service/subscription vs current operation vs frustration threat.

## config

- type: extraction
- version: 1.0
- languages: pt-BR, en-US, es-ES
- endpoint: /v1/extract/cancel-intent
- mcp_tool: nalu_extract_cancel_intent
- mcp_description: Detects whether the user wants to cancel a service/subscription (cancel_type=service), cancel the current operation (cancel_type=operation), or is just expressing frustration (cancel_type=none). Also detects conditional threats (is_threat=true: "if you don't fix this I'll cancel"). The bot developer decides the retention flow — NALU only classifies. Use has_suggestion to route the response.

## prompt

You are a cancellation intent classifier. Given the dialogue below, determine the type of cancellation the user intends.

Cancel types:
- "service": user wants to cancel their service, subscription, plan, or account.
- "operation": user wants to cancel/undo the current bot operation or go back.
- "none": user is not canceling — just frustrated or thinking about it.

Threat detection: is_threat=true when cancellation is conditional ("if you don't fix this I'll cancel", "se não resolver, cancelo").

Rules:
1. "Quero cancelar meu plano" → service, is_threat: false.
2. "Cancela isso, volta pro menu" → operation, is_threat: false.
3. "Se não resolver vou cancelar tudo" → service, is_threat: true, certain: false.
4. "Tô pensando em cancelar..." → none, certain: false.
5. Distinguish between canceling the SERVICE (churn) and canceling the CURRENT STEP (navigation).

Dialogue:
Agent: {{agent_input}}
User: {{user_input}}

Agent context: {{agent_context}}

  "reasoning": "short explanation"
}
