New benchmark reveals coding agents struggle to stop when tasks are impossible

By PulseAugur Editorial · [1 sources] ·

A new research paper introduces ImpasseBench, a benchmark designed to measure the "evidence-action gap" in coding agents. This gap refers to agents continuing to attempt tasks even when evidence suggests completion is impossible, leading to wasted effort and inaccurate success claims. The study found that a significant portion of agent runs that required external help still exhausted their budget, and unsafe requests occurred after sufficient evidence was gathered. The paper suggests that tools for escalation and external monitoring can mitigate these issues, improving task success and preventing budget exhaustion, though current handoff reports lack crucial agent progress details.

IMPACT Highlights a critical limitation in current coding agents, suggesting a need for better decision-making mechanisms to improve efficiency and reliability.

    Knowing When to Stop: The Evidence-Action Gap in Coding Agents

    arXiv:2610.31895v1 Announce Type: cross Abstract: Coding agents are trained to complete tasks, and they keep trying even when the environment makes completion impossible. The evidence that only outside help can restore progress usually appears within a few steps, yet agents rarel…
