Shepherd: A Runtime Substrate Empowering Meta-Agents with a Formalized Execution Trace
Shepherd is a new runtime substrate that enables meta-agents to supervise and optimize other agents through formalized execution traces, achieving 5x faster forking than Docker and demonstrating measurable improvements in coding assistance, optimization, and reinforcement learning tasks. The open-source system mechanizes core operations in Lean and enables replay, branching, and counterfactual exploration of agent behaviors.
