🤖AI Summary

SkillsBench introduces a new benchmark to evaluate Agent Skills - structured packages of procedural knowledge that enhance LLM agents. Testing across 86 tasks and 11 domains shows curated Skills improve performance by 16.2 percentage points on average, while self-generated Skills provide no benefit.

Key Takeaways
  • Curated Agent Skills improve LLM performance by 16.2 percentage points on average across diverse tasks.
  • Performance gains vary significantly by domain, from +4.5pp in Software Engineering to +51.9pp in Healthcare.
  • Self-generated Skills provide no performance benefit, indicating models cannot create the procedural knowledge they benefit from using.
  • Focused Skills with 2-3 modules outperform comprehensive documentation approaches.
  • Smaller models equipped with Skills can match the performance of larger models without Skills.
