Meet Shepherd: An Open-Source Python Substrate That Lets Meta-Agents Fork, Replay, and Revert Any Agent Run

Researchers at Northeastern University have introduced Shepherd, an open-source Python framework designed to manage the evolving state of long-running AI agents. By allowing agents to fork, replay, and revert their progress, the tool enables developers to fix errors in complex workflows without the need to restart the entire process or consume additional tokens to patch mistakes.
