The paper proposes Adaptive Skill Granularity, which lets coding agents choose at runtime between primitive tool calls, macro skills, or hybrid execution with fallback to micro-level recovery. Evaluations indicate fixed macro execution is brittle under mismatch, while runtime routing and macro-to-micro recovery improve robustness.
