SkillAudit: Ground-Truth-Free Skill Evolution via Paired Trajectory Auditing

In three linesSkillAudit is a framework for evolving LLM agent skills without ground-truth feedback. Via paired trajectory auditing, the system executes the same task with and without the candidate skill, then uses Process-Aligned Contrastive Evaluation to isolate behavioral changes. Across 89 tasks, SkillAudit achieves 73.9% average task reward vs 56.7% for static expert skill.
