SkillSandbox: Skill Verification via Dynamic Scenario Synthesis

Serin Kim, Kwangwook Seo, Dokyung Song +2

Self-evolving agents distill task-solving experience into skills for future reuse, but these skills can encode incorrect procedures or non-transferable knowledge. It is therefore c…

Verified Misguidance: Measuring Structural Citation Failures in Search-Augmented LLMs

Yongsik Seo, Wooseok Jeong, Eunyoung Kim +2

Users of search-augmented LLMs rely on citations as evidence that responses are grounded in real sources, and rarely verify the cited pages themselves. Millions of queries per day…
