SkillSandbox: Skill Verification via Dynamic Scenario Synthesis

To construct such situations, we propose SkillSandbox, a framework that dynamically synthesizes a task and its environment for each skill that are skill-relevant yet novel.

Key points

  • Self-evolving agents distill task-solving experience into skills for future reuse, but these skills can encode incorrect procedures or non-transferable knowledge.
  • It is therefore critical to verify each skill's reusability: whether its guidance remains useful beyond the experience from which it was distilled.
  • Such verification requires observing how a skill affects execution in new tasks, yet existing tasks may not expose the situations where the target skill can actually be exercised.
  • Further analyses examine whether these gains reflect accurate assessment of skill reusability and identify which components of SkillSandbox contribute to them.
