arXiv:2605.29463v1 Announce Type: new Abstract: Reflexion-style agents rely on self-generated reflections as memory, implicitly assuming that agents can accurately diagnose their own failures.We show that this assumption can fail systematically: across ALFWorld and HumanEval, agents store confident but incorrect interpretations of the task and continue acting on them across trials,even though the environment resets to the correct task each time. We call this failure mode memory confabulation and introduce the Reflection Repetition Rate (RRR), a log-based metric that detects repeated reliance o
The proliferation of AI agents relying on self-reflection as memory is revealing fundamental limitations in their diagnostic capabilities, prompting research into these failure modes.
This research highlights a critical vulnerability in autonomous AI agents, indicating that their self-correction mechanisms can systematically lead to confident, yet incorrect, behavior.
The assumption that AI agents can accurately self-diagnose failures is challenged, requiring new approaches to agent architecture and evaluation to prevent 'memory confabulation'.

- · Developers assuming perfect agent self-reflection
- · Systems relying on unchecked autonomous agent output
AI agent deployments may be delayed or require more human oversight due to concerns about reliable self-correction.
New techniques for external validation or 'truthfulness' in AI agent memories will become a significant area of research and development.
The development of 'digital lie detectors' or verification layers for autonomous AI systems could become a critical component of AI ethics and deployment frameworks.
