Research: Low-Cost Detection of LLM Agent Fake Successes
Acceptable_Block_591 · reddit · 2026-07-08
A first-time submitter is seeking an arXiv cs.AI endorser for their paper, which addresses how LLM agents sometimes claim a task is complete when it isn't ("fake success," e.g., falsely claiming a refund is processed).
The researcher pre-registered and validated a low-cost approach: post-execution, logs are programmatically analyzed to compare the agent's "claimed results" against the "actual results from tool calls." This catches fake successes without needing to invoke an LLM-as-a-judge for every trajectory.
