Agent Challenges

This is a gamified coding challenge system for Flow Nexus that handles everything from serving up algorithm problems to managing leaderboards and achievement badges. You'd use it when you want structured practice problems with automatic validation, or if you're building a competitive programming environment where users earn rUv credits for solving challenges. It covers the usual categories like algorithms, data structures, and system design, with difficulty tiers from beginner to expert. The interesting bit is how it tries to balance educational progression with competitive features, tracking things like solution efficiency and learning streaks alongside rankings. Solid if you need a turnkey challenge platform rather than rolling your own assessment logic.
