This post explains how to use the out-of-the-box Define Availability feature in ServiceNow’s Now Assist Skills to conditionally activate skills based on custom logic. The example focuses on the Incident Summarization Skill, but the approach can be adapted for other skills and use cases. By creating custom dictionary fields and using a business rule, you can control when a skill becomes available such as only when the combined word count of comments and work notes exceeds a threshold.
