arXiv:2607.01874v1 Announce Type: cross Abstract: Skills are becoming a reusable operational layer for LLM agents, encoding SOPs, domain rules, tool workflows, scripts, and validation routines. In realistic skill repositories, overlapping skills make reliable skill-use difficult. Final verifier success is too coarse for both evaluation and training, since an agent may pass through trial and error while selecting distractor skills, skipping required steps, composing workflows incorrectly or omitting final checks. We introduce SkillCoach, a self-evolving rubric framework for evaluating and enhan
The proliferation of LLM agents and the increasing complexity of their skill use necessitates robust evaluation and enhancement mechanisms to scale their utility.
Sophisticated readers should care because effective skill evaluation is critical for the reliable deployment and scalable improvement of AI agents across various domains.
The ability to automatically generate and evolve rubrics for agent skill evaluation provides a more granular and adaptable method for agent development than current coarse success/failure metrics.

AI agents become significantly more reliable and capable across complex tasks as their skill-use can be more precisely evaluated and refined.
The improved performance and trustworthiness of AI agents accelerate their integration into critical business processes, leading to widespread automation of white-collar workflows.
The enhanced ability of agents to self-evolve and execute tasks could lead to new forms of autonomous organizational structures and a substantial shift in the nature of work.
