What Can Component-Replacement Evidence Establish? A Critical Scoping Review of Local Decisions in LLM Agents

The article reviews how replacing components in language‑model agents affects execution trajectories and downstream outcomes. It maps 348 studies, analyzes 90 comparison records, and finds that while many studies report both local decision metrics and task endpoints, they rarely demonstrate matched comparisons or prove that improved local decisions drive task‑level gains. The review identifies three potential mechanisms—recovery and disruption, intervention timing, and downstream use—and proposes eight claim‑specific reporting items to clarify evidence quality.

SkillJuror: Measuring How Agent Skill Organization Changes Runtime Behavior

Agent Skills augment large language model (LLM) agents with procedural knowledge at inference time, but current benchmarks rarely distinguish what a Skill says from how it is organized. We study this distinction through Progressive Disclosure, where a concise root file points agents to supporting resources on demand, and compare it with a normalized flat baseline.
