Summary

This tutorial shows how to build a personal assistant agent that keeps working around the clock, even while you sleep. Using the Hyper Agent platform with a GPT-6 Astra model as the underlying brain, the creator walks through setting up an agent called Mini Zeno that checks a calendar, researches meeting attendees, and drafts email replies before the workday begins.

The build covers the key steps in order: writing a specific job description, connecting Gmail, calendar and Slack on a per-agent basis for better security, and adding custom MCP connections for other tools. The video recommends starting in plan mode so every action is reviewed and approved before anything is sent. It then shows how corrections are saved as persistent memories, how a repeatable “morning brief” skill is created with a quality rubric, and how to schedule it for 6 a.m. with a Slack trigger and a live mode that flags urgent email as it arrives.

In the final section, the single assistant becomes a manager that oversees its own team of specialized agents, including a researcher, a writer and a fact-checking reviewer. The creator estimates the setup costs a few dollars compared with thousands per month for a human assistant. Viewers interested in agent memory, scheduling and multi-agent delegation will find a practical template to adapt.
