From Migration to Calibration: Preserving Agent Capabilities across Models, Jurisdictions, and Scale

Read the original on arXiv AI →

The paper proposes a framework for agent calibration that ensures consistent capabilities when agents are deployed, migrated, or scaled across different models, harnesses, infrastructures, and user contexts. It defines standards for basic capabilities, technical environments, and user contexts, diagnoses gaps, applies revisions, and rechecks within fixed budgets, using diagnostic source behavior and mandatory tests to qualify agents. The framework includes semantic checkpoints, repair localization, and reusable configuration artifacts, and outlines an automatic calibration tool that relies on limited authorized user trajectories and tests, though empirical validation remains pending.

Evaluating Skills, Not Just Agents: Agentic Continuous Evaluation of Skills

The paper introduces ACES (Agentic Continuous Evaluation of Skills), a framework that evaluates reusable skills and capability packages by running paired live trials with and without a target skill, normalizing results into the Agent Trajectory Interchange Format (ATIF), and grading six runtime metrics to compute Skill Lift. ACES demonstrates that scan-only gates miss important aspects of skill performance, while the evaluation protocol reveals significant improvements in skill execution, behavior check, and skill efficiency across 145 real skills and 947 scored cases. The open‑source NVIDIA SkillEvaluator implementation enables reproducible, repository‑native assessment of agentic skills in production environments.

TRUSS: Towards Task-Reliable and User-Safe Automated Agent Skill Generation

TRUSS is a framework that generates and verifies automated agent skills, ensuring they are both functionally effective and safe. It first checks functional claims against evidence and evaluates artifacts against nine safety properties, then tests admitted skills in a controlled environment to capture execution traces and identify failures. The approach achieves perfect precision and recall in vulnerability detection, significantly reduces attack success rates, and boosts task effectiveness and security rates in skill generation benchmarks.
