SimPy skill: what it does and how to install it

What it does. Builds, inspects and tests bounded SimPy 4.1.2 models for queues, production, logistics and service systems. It covers event scheduling, resource contention, interrupts, monitoring, independent replications, warm-up handling and safe local command-line analysis with reproducible seeds.

When to use it. Use it for process-based discrete-event models with explicit time, entity, event and replication limits. It does not determine whether the conceptual model, distributions, estimands or causal interpretation are scientifically valid.
