In the latest season, you step inside a fully interactive AI coding assistant that turns natural language into bash commands, browses the web, connects to live data sources, runs org-approved skills, stores persistent memory, and orchestrates multi-agent workflows. Practice securing Agentic Workflows and Multi-Agent Communications as you work through five progressively harder levels. No AI or coding experience needed, just curiosity. Each season is self-contained, so you can jump straight into Season 3 or 4 without covering the earlier ones.
