It proposes SkillMentor, an RL‑based framework that generates diagnostic tasks and curates corrective skills. The contribution is demonstrating that learning blind‑spot detection can improve performance by 44.2% across two benchmarks. This work isolates diagnostic learning as the primary driver of improvement. ## Key Contributions - Blind‑spot diagnosis can be learned independently from executor adaptation, forming a new capability for self‑evolution. - SkillMentor achieves an average 44.2 % performance boost on AppWorld and BFCLv3 without modifying the underlying model or using human supervision. - The framework isolates diagnostic learning as the sole source of improvement, separating it from traditional execution updates. ## Methodology The authors train a Mentor policy via reinforcement learning to generate diagnostic tasks that expose recurrent failure modes. These failures are identified, clustered, and compiled into reusable corrective skills. Experiments are conducted under constraints that exclude executor weight updates and human‑provided labeled data, forcing all gains to arise from the learned diagnostic capability. ## Results Across both AppWorld and BFCLv3 benchmarks, SkillMentor improves executor performance by an average of 44.2 % relative to a baseline without diagnostic learning. The improvement is measured as task success rate or speed gain, and it persists despite no changes to the underlying model architecture. ## Significance This work shows that agents can evolve their behavior autonomously by discovering what they do not know, rather than merely fixing known failures. By learning blind‑spot diagnosis, SkillMentor reduces dependence on external human data and enables continual self‑improvement in a closed loop. The findings advance the field of autonomous system evolution and skill acquisition. ## Related Concepts Agent self‑evolution, blind‑spot diagnosis, reinforcement learning, skill curation, execution vs capability separation, AppWorld benchmark, BFCLv3 benchmark.
