  Handler implementation for the get_agent_prompt tool, which retrieves a base agent prompt and replaces template placeholders with form-specific details.

  case 'get_agent_prompt': {
    const { agent_number, form_number, form_path, pdf_path } = args;
  
    const basePrompt = await loadAgentPrompt(agent_number);
  
    // Customize prompt with form-specific info
    const customizedPrompt = basePrompt
      .replace(/\[FORM-NUMBER\]/g, form_number)
      .replace(/\[FORM-PATH\]/g, form_path)
      .replace(/\[PDF-PATH\]/g, pdf_path || '[PDF not specified]');
  
    return {
      content: [
        {
          type: 'text',
          text: customizedPrompt,
        },
      ],
    };
  }
