Can Semantic Geometry Teach an AI Judgement?

The paper investigates whether geometric representations of actions and policies can enable an AI agent to judge which rules to follow. Experiments across four studies found that geometric approaches failed to provide reliable pre-action judgment, and a lexical router, while efficient, still escalated all actions. The authors conclude that AI judgment likely requires an explicit consequence graph linking actors, authorities, policy conditions, exceptions, and action outcomes.

VeriGraph: Towards Verifiable Data-Analytic Agents

arXiv:2606. 16603v1 Announce Type: cross Abstract: LLM-based agents have demonstrated strong capabilities in data-intensive analytical tasks, yet their outputs are rarely verifiable: a reliance on linear text trajectories makes their reasoning difficult to audit.

EIO-Agents: The Missing Semantic Layer for AI Agent Evaluation

EIO-Agents introduces an open specification for interoperable AI agent evaluation, consisting of two layers: the Evaluation Intelligence Ontology (EIO) and the Portable Evaluation Record (PER). The EIO layer supplies a semantic framework that defines typed evidence, behavioral predicates, evidence contracts, claims, witness rules, proof status, recurrence, and computable derivations for metrics, findings, controls, and decisions such as PASS, REVIEW, or BLOCK. The PER layer offers a canonical, content‑addressed record of an evaluation that preserves the evidence‑to‑decision chain, enabling re‑derivation, explanation, and verification of the evaluation outcome.

When Reasoning Helps Action: Monitoring and Steering Chain-of-Thought in Vision-Language-Action Policies

The paper introduces TRUST, a token‑level reward model that predicts the correctness of partial chain‑of‑thought (CoT) traces in vision‑language‑action (VLA) policies, enabling monitoring and selective steering of reasoning. On driving and manipulation VLA benchmarks, TRUST improves reasoning accuracy and reduces collision rates and trajectory errors, though its impact on overall task performance varies across tasks. The study defines two evaluation axes—correctability and actionability—to assess when CoT can serve as a runtime safety interface.

From Risk Classification to Action Plan Remediation: A Guardrail Feedback Driven Framework for LLM Agents

arXiv:2606. 05805v1 Announce Type: new Abstract: LLM-based guardrails typically safeguard agents by evaluating proposed actions or inputs before execution, producing safety signals such as binary allow/deny decisions, risk categories, and/or explanatory rationales about potential policy violations.

Epistemic Disturbance in the Graph Model for Conflict Resolution: State-Preserving Actions, Four-Valued Assessments, and the Distinction between Capability and Intention

The paper extends the graph model for conflict resolution (GMCR) by introducing state‑preserving actions—announcements, leaks, and selective disclosures—that alter only the epistemic states of decision makers without changing the physical state. It augments GMCR with a four‑valued assessment framework distinguishing evidence for and against moves, showing how such evidence influences perceived move availability and stability judgments. The analysis clarifies how capability and intention assessments affect different stability concepts and illustrates the implications using the 1995 DVD format negotiation case.

Are LLM Safety Judges Policy-Invariant? A Three-Principle Stress-Test

The paper investigates whether large language model (LLM) safety judges are truly policy‑invariant, meaning their verdicts should depend only on the agent’s behavior and not on how the evaluation policy is phrased. It introduces three testable principles—rubric‑semantics invariance, rubric‑threshold invariance, and ambiguity‑aware calibration—and applies them in a stress‑test protocol across four agent‑class judges using trajectories from ASSEBench and R‑Judge. The study finds that current judges often change verdicts in response to both meaningful normative shifts and meaningless structural rewrites, with up to 9.1% of verdicts flipping due to content‑preserving rewrites and 18‑43% of flips occurring on unambiguous cases, indicating that safety scores conflate agent actions with evaluator wording. whyItMatters":"The findings reveal a hidden failure mode in safety evaluation that could mislead researchers about agent performance, underscoring the need for policy‑invariant judges and transparent reporting protocols."
