ShanLiangRen: A Nutrition Agent for Personalized Daily Meal Planning

ShanLiangRen is a nutrition agent designed to generate personalized daily meal plans that satisfy both user constraints and multidimensional nutritional goals. It transforms dietary specifications, nutrient data, user attributes, and natural language requirements into a constrained planning instance, then uses a retrieval‑augmented generation approach to narrow the candidate set from a large ingredient and recipe space. Finally, it refines plans via Pareto‑guided iterative revisions with an LLM, producing fully quantified meal plans with explicit ingredients, portion sizes, and compliance reports.

Textual Environmental Context and Spatial Graphs for LLM-Based Regional SST Forecasting

The paper introduces a method for sea surface temperature (SST) forecasting that combines textual environmental context with spatial graph representations for large language models (LLMs). Historical SST and anomaly sequences, date‑aligned environmental records, and static ocean knowledge are provided as textual input, while a static graph captures geographic–climatological relations and a dynamic graph captures recent SST correlations and tropical‑cyclone influence. The approach achieves the lowest mean absolute error and highest R² among compared methods over ten forecast steps in the South China Sea, and includes a rule‑based module that links predicted trends to source‑linked contextual explanations.

Confidence Reasoning Graphs: Structured Confidence Estimation for LLM Agents

The paper introduces Confidence Reasoning Graphs (CRGs), an inference-time framework that estimates the probability an LLM agent has successfully completed its task using a single trajectory without requiring privileged model access or training data. CRGs decompose the agent’s overall claim of success into contextualized sub-claims, estimate confidence for each terminal claim based on trajectory evidence, and aggregate these into an overall confidence estimate. Experiments across multiple benchmarks, models, and agent frameworks show that CRGs produce better-calibrated confidence and more effective risk-aware decision making than existing verbalized, sampling-based, and white-box surrogate methods, while also providing transparent, auditable evidence for each estimate.

DAEDALUS: Bootstrapping Agent Memory from Self-Generated Tasks

DAEDALUS is a method that builds reusable memory for large‑language‑model agents by having an explorer agent generate self‑created tasks and a solver agent attempt them. When the solver fails, a heuristic is extracted and only accepted after repeated successful use, then added to a memory bank for future test‑time use. Experiments on AppWorld, τ²‑bench, and AutomationBench show that DAEDALUS raises mean success rates by up to 15.9 points and pass⁵ by up to 2.2× compared to a no‑memory baseline, while also providing a cost‑effective alternative to training‑task or oracle‑verifier approaches.

Agent in a Bottle: Can LLM Agents Turn Their Capabilities Into Cheap, Scalable Artifacts?

The paper introduces the concept of "bottling"—the ability of large language model (LLM) agents to transform general capabilities into task‑specific, cost‑effective solutions for large, repetitive workloads. It presents BOTTLED, a benchmark where agents receive an unlabelled workload and must complete it within fixed time, compute, and API budgets, choosing strategies such as training small models or writing reusable programs. Experiments across ten models and three tasks show that strong zero‑shot performance does not guarantee effective bottling, yet bottling can still achieve substantial cost savings and competitive performance compared to specialized cheap inference models.

APEX: Active Protection at Execution Boundaries for LLM Agents

The paper introduces APEX, an active defense for large language model agents that protects against indirect prompt injection by enforcing safety at execution boundaries. APEX uses an evidence‑gated prevention contract and deception‑based exposure to ensure that only authorized effects, endorsed by the task, are executed. Evaluation shows APEX achieves near‑zero attack success across multiple benchmarks and capability‑unit types, outperforming 13 baseline defenses.
