Agentic AI (AI Agent) Development Guidelines and Use Cases (Hands-on Experience)

[John Zhang1]

With the Yokohama release, ServiceNow introduced specialized AI agents that optimize operations. These agents handle both repetitive and complex tasks, boosting efficiency and allowing employees to focus on strategic work.

By adopting Agentic AI, organizations improve automation, reduce manual workloads, and enhance productivity, driving a transformative shift in business operations.

ServiceNow Agentic AI streamlines workflows across IT, HR, security, and customer service. For example, in an IT service desk, Agentic AI can manage password resets by understanding requests, verifying security, and executing the reset automatically.

The propose of this blog is to walkthrough the Agentic AI development steps so you are able to use this blog as a reference to build your own Agentic AI solution.

AI Agent Control Tower Process

A system where specialized AI agents collaborate as a team to achieve specific business outcomes. These agents can:

1. Autonomously analyze complex situations
2. Generate strategic insights
3. Execute actions aligned with business goals

AI agents utilize various tools to execute defined use cases. AI Agent Studio guides users in leveraging AI agents effectively, while AI Orchestrator ensures seamless collaboration among them. Establishing an AI Agent Control Tower enables governance, tracking of use cases, and measuring value across the enterprise.

AI Agent Orchectrator

In Agentic AI within ServiceNow's AI Agent Studio, the Orchestrator plays a crucial role in coordinating and managing workflows across multiple AI agents and enterprise systems. It acts as the central control mechanism, ensuring that different AI agents execute their tasks in a structured, efficient, and policy-compliant manner.

The Orchestrator acts as a coordinator, facilitating communication between agents to complete complex tasks. It can also retrieve missing context from users when needed. AI agents operate iteratively, seeking assistance from the Orchestrator if they encounter difficulties.

Orchestrator's Role in AI Agent Studio Use Cases

1. Task Coordination & Execution - manages the interaction between multiple AI agents, ensuring that tasks are executed in the correct sequence.
2. Dynamic Decision-Making - Can invoke AI models dynamically based on the scenario.
3. Seamless Integration with Enterprise Systems - Works with ServiceNow workflows, CMDB, and third-party APIs to enable end-to-end automation.
4. Handling Multi-Step Workflows - Enables chained execution of AI-driven tasks among multiple AI Agents.
5. Policy & Governance Enforcement - Enforces governance rules to ensure that AI agents adhere to compliance and security standards.

Pre-requirement to use AI Agent Studio 

1. AI Agent Studio  - new AI Agent Development tool in Yokohama release
2. Now Assist Skill Kit - new feature in Xanadu release.  This feature manages and coordinates multiple AI agents, ensuring they work harmoniously to achieve defined business objectives. It facilitates seamless collaboration among native and third-party AI agents across departments like IT, HR, and customer service
3. The requied roles for both Now Assist and AI Agent Studio:
