What Keeps Agent Skills from Being Reusable? Evidence from 138K SKILL.md Files
TL;DR
A comprehensive analysis of 138,133 SKILL.md files reveals that 91.8% contain defects, primarily due to poor metadata and organization, hindering the reusability of agent skills for Large Language Model (LLM) agents.
✦ Why It Matters
Focus on improving routing metadata and organization in agent skills to enhance reusability.
Key Takeaways
- Ensure routing metadata is valid for better skill retrieval.
- Adopt specification-aware practices to reduce defects.
- Implement lightweight linting and automated repair processes.
- Organize skill content effectively to enhance usability.
How It Works
The analysis utilized a two-tier defect taxonomy based on official specifications to categorize issues in SKILL.md files. A deterministic routing stress test was conducted to evaluate the impact of routing metadata on skill retrieval reliability.
