New benchmark tests LLM agents' ability to form reusable skills

Researchers have introduced SkillEvolBench, a new benchmark designed to evaluate how well large language model agents can transform episodic experiences into reusable procedural skills. The benchmark features 180 tasks across six environments, organized by task families with shared underlying procedures. Initial tests across various agent configurations revealed that current agents struggle to form robust, reusable skills, often performing better with raw trajectory reuse than with distilled skills, indicating that current abstraction methods may discard useful contextual information.

IMPACT This benchmark could drive progress in developing LLM agents that can generalize knowledge and form reusable skills, moving beyond task-specific memory.

    SkillEvolBench: Benchmarking the Evolution from Episodic Experience to Procedural Skills

    arXiv:2605.24117v1 Announce Type: new Abstract: Large language model (LLM) agents accumulate rich episodic trajectories while solving real-world tasks, but it remains unclear whether such experience can be distilled into reusable procedural skills. We introduce SkillEvolBench, a …

    SkillEvolBench: Benchmarking the Evolution from Episodic Experience to Procedural Skills

    Current large language model agents struggle to form robust reusable skills from episodic experience, with raw trajectory reuse often outperforming distilled skills due to discarded contextual cues.
