Skill ordering and grouping measurably changes agent runtime behavior (SkillJuror)

arXiv·medium signal

SkillJuror (arXiv 2606.11543, June 2026) shows that the arrangement of an agent's available skills — not just which skills exist — produces measurable deltas in success rate, token consumption, and execution speed. The takeaway for Claude Code / agent-skill setups: order and group skills deliberately by frequency of use, task relevance, and execution dependencies rather than dumping them in arbitrarily. It's a complement to skill-consolidation work: even a good skill set underperforms if presented in the wrong order.
