Agents & Dragons: Once Upon Agentic AI Workshop [AWS User Group Bratislava]

This time we’re doing something different. Instead of talks, we’re running a three-hour hands-on workshop where you’ll build your own AI Game Master: an agent that runs a fantasy role-playing adventure, rolls the dice, knows the rules and keeps track of your characters.

Along the way you’ll learn how to build agents with Strands Agents, the open source SDK from AWS. You’ll start with a single agent, then give it vended and custom tools, connect it to external services over MCP, and finally build a multi-agent system where a Rules Agent and a Character Agent talk to each other over A2A while the Game Master orchestrates everything. By the end of the evening, everyone leaves with a working AI Game Master they built themselves.

The workshop is level 300, so you should be comfortable with Python and the command line. Every attendee gets a free AWS Builder Center sandbox environment, so you don’t need your own AWS account or a credit card.

⚠️ Limited to 20 seats.
Since this is a hands-on workshop, capacity is small. If your plans change, please cancel your RSVP so someone from the waitlist can take your spot.

🗓️ Agenda
17:30 Doors open & setup check
18:00 to 21:00 Workshop
Please come at 17:30. We’ll use the first minutes to make sure everyone is set up and ready, so we can all start building together.

🛠️ Before you come (please don’t skip this)
Setup problems are the most common reason people lose time at workshops like this, so please prepare everything at home:
✅ Create your AWS Builder Center account in advance. Creating accounts for the whole room at once slows everyone down.
✅ Don’t launch any Builder Center sandbox from November 4 until the event. Sandbox access is limited to one workshop per week per account, and we can’t unlock it for you on site.
✅ Bring your own laptop and charger. A tablet or Chromebook won’t be enough. We recommend a personal laptop, because corporate firewalls and certificate injection have blocked Bedrock API calls at previous events. If a work laptop is your only option, check that you can install software and make outbound HTTPS calls to AWS.
✅ Have an IDE or editor installed, whichever one you’re fastest in (VS Code, Kiro, PyCharm, Neovim…).
✅ Have git installed and check that you can clone a public repo from GitHub. We’ll start by cloning aws-samples/sample-once-upon-agentic-ai.
✅ Have Python 3.10 or later installed. Check with

python --version

✅ Install uv. The workshop uses it to manage Python and dependencies, and it’s the most common place people get stuck at the start.
