What makes this environment useful?

Multi-agent environments include two or more decision-makers sharing or competing over state. Their evaluation must account for joint outcomes, individual contributions, and possible emergent failure modes.

Example agent workflows

  • Coordinate planning and execution agents on a shared task
  • Allocate scarce resources across competing agents
  • Negotiate task ownership while maintaining a common objective

Core components to specify

Agent-specific observations and action spaces
Shared world state and controlled communication
Team and individual reward definitions

How to measure success

Useful evaluation signals include joint completion, coordination cost, fairness or incentive robustness. The precise verifier depends on the task. Prefer checks against underlying system state and executable tests over subjective presentation scores.

DESIGN WATCH-OUT

A shared reward can hide free-riding. Define individual incentives and evaluate coordination failures.
