This session covers how to design evaluation frameworks for multi-step, tool-using agents; how to instrument and trace agent decisions for debugging and audit; and how to recognize and respond to common production failure modes. **Who is this for?** This workshop is open to everyone curious about building with agentic AI. Technical background and Python knowledge recommended. **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend.

This is a **shuffle**/**cutting shapes** class for **beginner** and **intermediate** shufflers where we'll be learning a **choreo** and practise it to various speeds. **This time, we're gonna learn the second part of the choreo that we started last time. You won't need the first part - we'll work on the second part only and then combine them at my next class at the beginning of May. However, you can already learn/refresh the first part with the help of the videos in our telegram channel - link at the bottom of this post!** **What you need to bring with you:** **Shoes**: If you'd prefer not to shuffle in socks, please bring a pair of dedicated clean athletic shoes with white soles. **Water**: because Shuffling is like an intense cardio workout :) **Fee**: 10€ (in cash or paypal **after** the event) to cover the cost of the rent, because we're not doing it for profit.

What will happen: **Beginner shufflers** will get the chance to learn some basic steps and practice them stress-free in a short choreo. **Intermediate shufflers** will learn to vary these basic steps with additional leg and arm movements, learn to combine them in new ways, keep practicing their foundations, and try to integrate the new combos into their freestyle. Teacher: Ina P.S. You're welcome to join our Telegram group where we share choreos, combos, music, etc. https://t.me/joinchat/73TM5UceauA5YmQy P.P.S. Classes at Milastr. 4 take place every Friday!
