LCGuard: Adversarial Training Framework for Safe KV Cache Sharing in Multi-Agent LLM Systems
LCGuard introduces a framework for preventing sensitive information leakage when multi-agent LLM systems share KV caches as a latent communication channel. The approach formalizes leakage operationally via reconstruction: a shared cache artifact is deemed unsafe if an adversarial decoder can recover sensitive inputs from it. An adversarial training loop pits a reconstructor against LCGuard's representation-level transformations, which aim to preserve task-relevant semantics while suppressing recoverable sensitive content. Empirical results across multiple model families and multi-agent benchmarks show reduced reconstruction-based leakage and attack success rates with competitive task performance.
Code as Agent Harness: A Survey of Code as Operational Substrate for Agentic AI Systems
This survey paper introduces the concept of 'code as agent harness,' framing code not merely as output but as the operational infrastructure for LLM-based agents—covering reasoning, action, environment modeling, and execution-based verification. The authors organize the analysis across three layers: harness interface, harness mechanisms (planning, memory, tool use, feedback control), and scaling to multi-agent systems. Applications span coding assistants, GUI/OS automation, embodied agents, scientific discovery, and enterprise workflows. Open challenges include evaluation beyond task success, verification under incomplete feedback, and human oversight for safety-critical actions.
Governed Evolution of Agent Runtimes through Executable Operational Cognition
This paper proposes a framework for governed runtime evolution in multi-agent systems, formalizing agent-generated code artifacts as persistent runtime capabilities rather than transient outputs. It introduces HarnessMutation, a lifecycle-aware mechanism for runtime adaptation operating under explicit validation, traceability, evaluation, and rollback constraints. The framework models agent self-modification as a bounded, observable, and auditable process over persistent operational memory, building on prior 'Code as Agent Harness' work.
