# Summary: SkillCommit

**Original paper:** [arXiv: 2608.15165](http://arxiv.org/abs/2608.15165v1)

## Summary
SkillCommit turns agent experience into a hierarchical skill library while preserving behaviorally validated patches. Retrieval proposes related skills, then transfer and mechanism checks determine whether abstraction is safe. Experiments on RuleArena, OpenExempt, and KOR-Bench report gains across model scales and families.

## Why it matters
Long-lived agents need controlled skill consolidation, not blind semantic merging. Validated patches provide a safer unit for continual improvement and cross-model transfer.
