Large-Scale Tool Environments Mirror Real Enterprises

The author adds that PlanBench-XL places agents in a retail world featuring over 1600 tools, though agents never see the complete toolset directly.
This closely reflects real enterprise scenarios: numerous tools exist, but they simply cannot all fit into the context window.
The text also notes that in such multi-turn, long-horizon environments, a single domain might contain 100+ tools. Consequently, these benchmarks reveal significant drops in model performance, highlighting the need to train models to actively explore tool libraries.
