CoworkEnv: Synthesizing Training Environments for Long-Horizon Cowork Agents

We present CoworkEnv, a capability-guided framework for synthesizing executable training environments for AI coworkers.

Key points

  • AI coworkers must coordinate tools, communicate across turns, and act on changing workspace state while respecting workflow constraints.
  • An SFT-only extension to ClawMark demonstrates applicability across coworker benchmarks.
  • We further compare RL training dynamics across configurations that vary reward processing and credit assignment.
  • Improving training rewards provide preliminary evidence that the constructed environments support policy optimization.
