Skill kit custom output field population

❓ Question: Custom Output Fields Not Populating in Now Assist Skill Kit

Hi Community,

I'm working with the Now Assist Skill Kit to create a generative AI skill that extracts incident details from a transcript — such as urgency, category, subcategory, assignment group, and caller — and returns them as structured outputs.

I’ve defined the following custom output fields in the skill:

• urgency (String)

• category (String)

• subcategory (String)

• assignmentgroup (String)

• ncaller (String)

In the prompt, I have clearly instructed the model to return a JSON response like:

{
  "description": "User cannot access payroll...",
  "category": "Software",
  "subcategory": "Application",
  "urgency": "1 - High",
  "impact": "1 - High",
  "assignmentgroup": "Access Team",
  "ncaller": "Sarah (Finance)"
}

However, while testing:

• The response field is populated with the full JSON string.

• My custom output fields (e.g., urgency, category) are not populated individually in the Test panel.

🔍 What I’ve Done:

• Set Response format = Structured (JSON).

• Output fields are defined correctly with matching names.

• Prompt returns well-structured JSON.

• Tried both model_output and plain JSON return structures.

• Using Now LLM Generic in the default config.

❗ What am I missing?

• Is there a special binding or parsing setting I need to enable for the LLM to map outputs to the skill output fields?

• Do I need to parse the model_output key manually?

• Or is there a more specific response mapping mechanism for custom fields in Now Assist?

Any guidance or examples from the community would be greatly appreciated. Thanks in advance!

Would you like me to post it for you or refine this further for Developer Portal/Slack/Now Community based on your preferred channel?

Hi @manjee_91 !

The following Skill Kit Article (updated 3 weeks ago) clearly shows that, as of now, there's no functionality to create a mapping to outputs. Hope they'll add it soon.
