    Before you begin

    Role required: sn_skill_builder.admin

    Procedure

    1. Navigate to All > Now Assist Skill Kit > Home.
    2. Select the skill that you want to configure.
    3. In the Skill contents sidebar, select the prompt that you want to configure.
    4. Select Manage prompt, then select Prompt settings.
    5. Fill in the fields.
      Table 1. Prompt settings
      Field Description
      Model The model is the large language model (LLM) that you want to use for the prompt.
      Temperature The randomness and creativity of the output. A higher value increases the randomness. The value must be between 0 and 1.
      Thinking mode Controls how much reasoning effort the LLM applies when generating a response. Higher levels improve output quality but increase latency. Thinking mode is available when using llm_generic_small_v2 or llm_generic_large_v2.
      Maximum response tokens The maximum number of tokens the model can return. Token limits are set by your admin for controlled usage.
      Maximum request tokens The maximum number of tokens allowed in a request. Token limits are set by your admin for controlled usage.
      Structured output Returns prompt responses in a consistent JSON format.
      Note:
      Only Google Gemini and Azure OpenAI support structured output. This option is not available when using Now LLM Service.
    6. To configure when this prompt runs, select Manage prompt, then select Usage conditions.

      Usage conditions are filters built from your skill inputs. When a skill has multiple prompts, usage conditions determine which prompt runs for a given execution. The prompt without usage conditions is the default and runs when no other prompt's conditions are met.

      Important:
      Usage conditions require at least one skill input to be defined. If your skill has no inputs, the Usage conditions panel will have no available keys to filter on.

    What to do next

    After you configure your prompt settings, you can test your skill. To learn more about testing skills, see Test a prompt.
