Halite II is an open-source challenge framework that hosts turn-based strategy matches between user-written bots. Each turn, agents receive a map state, issue movement and attack commands, and compete to control the most territory. The platform includes a game server, map parser, and visualization tool. Developers can test locally, refine heuristics, optimize performance under time constraints, and submit to an online leaderboard. The system supports iterative bot improvements, multi-agent cooperation, and custom strategy research in a standardized environment.

pyafai is an open-source Python library designed to help developers architect, configure, and execute autonomous AI agents. It offers pluggable modules for memory management to retain context, tool integration for external API calls, observers for environment monitoring, planners for decision making, and an orchestrator to run agent loops. Logging and monitoring features provide visibility into agent performance and behavior. pyafai supports major LLM providers out of the box, enables custom module creation, and reduces boilerplate so teams can rapidly prototype virtual assistants, research bots, and automation workflows with full control over each component.
