## Summary

Infini-AI-Lab has released Hermit, an open-source Python framework that trains an external harness adapter while the agent's model and harness stay frozen. Developers can adapt Codex or Claude Code agents to new tasks without fine-tuning or forking the harness. The article reports self-reported gains on OfficeQA, CL-Bench and ServeLearnBench, including 0.795 accuracy for the MWM adapter on CL-Bench database exploration versus 0.580 for the in-context baseline.
