ScrambleToolBench - Base - Episode Completion Rate: leaderboard
ScrambleToolBench (arXiv 2608.02358v1, Table 2): agents work through five sequential tasks using tools whose names and argument schemas are obfuscated, so tool behaviour must be discovered by probing. Share of 20 scrambled base-condition episodes in which all five tasks are solved, percent. Higher is better.
Metric: Episodes with all five tasks solved (%). Source: arxiv.org. Saturation forecast: Estimated already saturated. 15 models tracked.
