About

This weekend's challenge is The Bazaar, built with Causa Prima. Your team builds an agent that negotiates one on one with the other teams' agents, and on Sunday afternoon every agent enters a live tournament. The full brief is presented on Friday at 19:00. Everything is built during the weekend, with Claude Code in how you build and Claude in what you ship.
