Abstract

Large-language-model (LLM) agents perform well in embodied benchmarks but are costly, stochastic, and difficult to audit. We propose an LLM-free zero-shot decision agent for ALFWorld that combines structured commonsense priors with adaptive calibration. The agent uses object-location priors, task templates, synonym mappings, and a hierarchical state controller over admissible commands. Because every decision is traceable to explicit knowledge entries, success and failure signals update only the responsible entries rather than all parameters. On 134 ALFWorld valid_unseen tasks, static priors obtain 67.2% success; symmetric calibration over P(obj,loc), M(target,entity), and S(word) improves this to 73.9%, with one-round convergence and CPU-only execution. We also observe that 34/134 tasks contain description-environment inconsistencies; on the consistent subset, our system reaches 93.0%. The results show that interpretable structured priors can be a practical alternative for well-specified embodied decision making.

SCOPE: Score-Isolated Agentic Optimization for Video World Models

It is suggested that reliable inference-time adaptation requires not only better proposals, but also a principled mechanism for deciding which updates should become part of the deployed system.

Structured LLM Reasoning for Zero-Shot Human--Robot Coordination Under Hidden Goals

The results suggest that systematically decomposing the team decision problem, using LLMs as tractable surrogates for otherwise intractable inference and planning computations, and retaining conventional verification for physical feasibility can improve both task coordination and the human experience.

Do Agents Know When They Succeed? Calibrating Agent Confidence from Internal Representations

This paper investigates whether model's internal representations provide stronger signals of eventual task success in multi-turn agentic setups, and introduces two complementary methods: Latent Trajectory Dynamics (LTD) and the Action Representation Probe (ARP), which predicts success from representations formed at act...

Belief-State Engine: Augmenting LLMs for Principled Planning Under Partial Observability

It is proved that the LLM paired with the BSE is a sound Markov policy on the belief MDP induced by the underlying POMDP, and inherits the Bellman optimality guarantees of classical POMDP theory, provided the LLM is never exposed to the raw history.
