# FlowEvo Lets LLM Agents Co-Evolve Workflows and Reusable Skills

The method turns useful reasoning procedures used at inference time into a library of executable skills, so that agents do not have to rediscover the same solutions on every task.

A new paper introduces FlowEvo, a framework in which large language model (LLM) agents co-evolve their inference-time workflows and a library of executable skills. The motivation is a known inefficiency. Agents build fresh workflows that co…
