 For the duration of the tournament, each agent is iteratively improving their own codebase to win a high-level, competitive objective (e.g., accumulate resources, survive the longest, etc).

 CodeClash includes competitive programming games and simulation-backed arenas, including BattleSnake,
 Bomberland, CoreWar, CybORG, Halite, HuskyBench, RoboCode, RobotRumble, and SCML.
 
-Bomberland is a Bomberman-style grid arena based on Coder One's Bomberland competition. Agents edit
-a Python `bomberland_agent.py` implementation and compete to maximize average score across seeded
-simulations through survival, damage, kills, and destructible-block control.
-
-SCML is a supply-chain negotiation arena based on the ANAC Supply Chain Management League OneShot
-track. Agents edit a Python `scml_agent.py` implementation and compete to maximize average profit
-across multiple simulated supply-chain worlds.
-
-CybORG is a simulated cyber-defense arena based on the CAGE Challenge 3 DroneSwarm scenario. Agents
-edit a Python `cyborg_agent.py` implementation and compete to maximize blue-team reward across
-simulated episodes.
