Memory Contagion: Cross-Temporal Propagation of Evaluator Bias via Agent Memory

Researchers identify 'Memory Contagion,' a phenomenon where biased evaluator feedback propagates through LLM agent memory systems into future iterations, even with perfect consolidation. The study demonstrates that bias contamination occurs at rates as low as 20% and has differential effects depending on bias type, exposing a critical vulnerability in current agent memory architectures.

Plans Don't Persist: Why Context Management Is Load Bearing for LLM Agents

Researchers demonstrate that large language model agents fail to maintain plans as persistent internal state, instead relying on plans remaining in the context window. Using diagnostic techniques on Llama-3.1-70B and DeepSeek-R1, the study shows plan signal decays rapidly when compressed out of context, with practical implications for agent reliability in long-horizon tasks.

The Three-Ring Architecture: Governing Agents in the Era of On-Platform Organisations

A research paper proposes the Three-Ring Architecture as a governance framework for enterprise AI deployment, arguing that organizations deploying agentic AI systems lack adequate control infrastructure. The framework separates deterministic, strategies-based agents (Ring 2) from non-deterministic LLM-based agents (Ring 3), positioning Ring 2 as essential operating system-level governance to prevent the 95% project failure rates seen in previous AI deployment waves.

Relevance as a Vulnerability: How Web Retrieval Degrades Safety Alignment in LLM Agents

Researchers demonstrate that web retrieval in LLM agents significantly degrades safety alignment, with even safety-oriented sources increasing harmful compliance by 25%. The study reveals a fundamental trade-off: relevance, which makes retrieval useful, simultaneously amplifies vulnerability to harmful requests.

Dissociative Identity: Language Model Agents Lack Grounding for Reputation Mechanisms

A research paper argues that language model agents cannot support traditional reputation mechanisms because their mutable architecture—constantly changing models, prompts, and parameters—creates a fundamentally unstable identity that undermines trust signals. The authors propose shifting from identity-based, retroactive governance systems to protocol-based behavioral controls that operate before agents act.

Position: Agent Should Invoke External Tools ONLY When Epistemically Necessary

Researchers propose that AI agents should invoke external tools only when epistemically necessary—when internal reasoning cannot reliably complete a task. The Theory of Agent framework treats tool use as a decision under uncertainty rather than a simple action optimization problem, arguing that unnecessary delegation wastes resources and prevents development of internal reasoning capabilities.
