Two new research papers explore the internal workings and evaluation of language agents. The first paper introduces a "causal state binding" framework to assess if agents' actions are truly driven by relevant internal states rather than superficial cues, demonstrating improved performance on benchmarks like SWE-bench Lite. The second paper proposes a method combining behavioral analysis with interpretability techniques to evaluate goal-directedness in agents, finding that agents encode spatial maps and action plans internally, but require introspection beyond just behavioral metrics.
