ToolRobustBench - Tool Output: leaderboard

ToolRobustBench (Jilin University, 2026) is a stage-wise diagnostic benchmark for tool-calling agents, with perturbation families aligned to tool selection, argument binding, output handling and runtime feedback. The success rate is the share of instances with a fully correct tool call on a native 0 to 1 scale, higher is better, under noisy, missing or conflicting returned evidence after the call.

Metric: Success rate (0-1, native; noisy, missing or conflicting returned evidence after the call; over ToolRobustBench single-family perturbation instances (clean, light, medium, heavy); binary per-instance tool-call success). Source: arxiv.org. Saturation forecast: Around February 2027. 7 models tracked.
