During this virtual meet-up we'll share some lessons learned and best practices on the use of Agent Builder & Maestro in a practical use-case within HR. During the Agentic Automation Summit of UiPath in Nieuwegein on June 11, Tacstone Technology presented the HR-agent solution together with Mediq. This HR agent helps to answer incoming questions in the shared e-mailbox. It makes use of different tools in SAP SuccessFactors, but also context grounding (RAG) such as HR related documents. Two weeks ago we only had 20 minute to present some key highlights. This session is intended to share lessons learned from the automation developer perspective. Hands-on and pragmatic. To get inspired and learn best practices for your own agentic automations! 📕 Agenda: POC Approach Solution (demo Maestro & Agent Builder) Lessons Learned Q&A 👨‍🏫 Speakers: Jack Klein-Schiphorst, Lead Developer @Tacstone Technology Dion Mes, Presales Engineer @UiPath This session streamed live on July 10, 14:00 CET.

Tools

Context
Agent uses Retrieval Augmented Generation (RAG)
You can add Context by creating an Index
Example: ”How many vacation days do I have in total per year?”
Question about non existing knowledge? “What is the chamber of commerce number of Mediq
Nederland B.V.?”

13. 13
Escalations
“What happens when the agent cannot answer a question or an error occurs?”

14. 15
Evaluations
“Small changes can impact previous runs”

15. 16
Wrap up
Describe roles, not workflows
Modular agent is smarter than hardcoded flows
Powerful + safe with escalation and evaluations
