Technical Implementation

AI Chatbot Service

@Injectable()
export class AdmissionChatbotService {
  async chat(inquiryId: string, message: string): Promise<ChatResponse> {
    // Get school context
    const schoolInfo = await this.getSchoolInfo();
    const feeStructure = await this.getFeeStructure();
    
    // Build system prompt
    const systemPrompt = `You are an admission assistant for ${schoolInfo.name}.
    
Fee Structure:
${JSON.stringify(feeStructure)}

Guidelines:
1. Be helpful and professional
2. Provide accurate admission information
3. Offer to schedule school visits
4. Respond in Hindi/English based on user`;

    // Call Claude API
    const response = await this.anthropic.messages.create({
      model: 'claude-sonnet-4-20250514',
      system: systemPrompt,
      messages: [...history, { role: 'user', content: message }],
    });

    // Save chat history
    await this.saveHistory(inquiryId, message, response);

    return { message: response.content[0].text };
  }
}
