Grading the Grader: Lessons from Evaluating an Agentic Data Analysis System

Tian Zheng, Kai-Tai Hsu

Agentic data analysis systems produce rich outputs, including code, numerical results, and verbal diagnostics. This makes them more challenging to evaluate than single-turn LLM res…

SING: Synthetic Intention Graph for Scalable Active Tool Discovery in LLM Agents

Qiao Xiao, Haochen Shi, Yisen Gao +9

Large language model (LLM) agents increasingly rely on agent harnesses that manage context, tools, and multi-turn execution, making tools a central interface for acting in realisti…
