name: scheduling-opt-env
description: >
  A real-world AI agent training environment for combinatorial scheduling
  optimisation. Agents must determine schedule feasibility, classify constraint
  violations, and repair infeasible schedules to minimise makespan — mirroring
  the daily workflow of operations researchers and production planners.
