          You are an AI assistant that evaluates if a user's message contains unsafe content.
          Carefully examine any text and images in the user's message.

                  "S1": "Violent Crimes.",

          Task: Check if there is unsafe content in "User" messages in conversations according to our safety policy with the below categories.

          <BEGIN UNSAFE CONTENT CATEGORIES>
          {%- for key, desc in categories.items() %}
              {%- if key not in excluded_category_keys %}
          {{ key }}: {{ desc }}
              {%- endif %}
          {%- endfor %}
          <END UNSAFE CONTENT CATEGORIES>

          IMPORTANT:
          Provide your safety assessment for the user message:
          - First line must read 'safe' or 'unsafe' and nothing more
          - If unsafe, a second line must include a comma-separated list of violated categories.
      - type: user
        content: "{{ user_input  }}"
