In May 2025 we released version 4.0.3 of Now Assist Skill Kit. This version, available for those on at least the Xanadu Patch 9 & Yokohama Patch 3 versions, introduced a number of new features.
Automated prompt optimization (APO)
Automated prompt optimization, available for custom skills developed within Now Assist Skill Kit, helps remove the guesswork when exploring how to write a good prompt. It reviews how a particular prompt performs against a dataset and offers an optimized version for the desired outcome.
APO works by following the process below:
- User creates a draft prompt for a custom skill
- APO is configured, with the user providing the following details:
- Prompt to be optimized
- Dataset to use in the validation process (minimum 100 records)
- Optimization instructions (such as the goal and desired output format for the prompt)
- Optimization run completes, returning results to the user
- User adjusts prompts based on the guidance from APO to utilize within the custom skill
The evaluation metrics used to determine the performance of a prompt include:
- Correctness: Is the output from the LLM accurate given the source material?
- Faithfulness: Is it hallucinating, or coming to unsupported conclusions?
- Latency: How long does it take to receive a response?
Predictive Intelligence Tool
Predictive intelligence is a feature available within ServiceNow that allows you to create models that enable you to predict, estimate, and identify patterns within your data. You can add a Predictive Intelligence tool to your custom skill to help identify records that match the pattern defined within the model. Examples include finding similar incidents, or retrieving a classification for an input record based on others.
To add a Predictive Intelligence model to your custom skill, you first have to create and train your model.
Deploy to Now Assist Context Menu (NACM)
The Now Assist Context Menu is a component that allows you to augment text using generative AI. You can add the NACM to any field through following the documentation, but you will notice it provided for a number of OOTB skills such as Agent Chat, Resolution Note Generation, and Email modules. OOTB NACM options include the ability to Elaborate, Shorten, and Analyze text, however, you can also create and deploy your own custom skills for use within this menu.
When using NACM for custom skills, you must perform the following steps:
- Create and publish your custom skill within Now Assist Skill Kit
- Activate your custom skill within Now Assist Admin console, ensuring you set the NACM as a display option.
- Create or edit an existing a NACM configuration record to determine where and how the NACM should present to users
- Adjust the script within the wwna_quick_actions tbale to connect the input from your component to the input expected by the skill
Hello,
Thank you very much for creating the content on these points. I have one query: I am curious if you could share a document link or any resources that explain how to add NACM to a custom location using the UI Builder.
