Vagus — A Vagal-Nerve Layer for Safer Agents
Vagus 在 LLM/Planner 与执行器之间引入链上"迷走神经层"，用传入证据(Afferent)、张力(VTI)与三态(ANS)、制动(Vagal Brake)、反射弧(Reflex)、短时效能力令牌(Capability Token) 来防止不对齐与危险动作。
Core Features
Three fundamental pillars that make Vagus a comprehensive safety layer for autonomous agents
Safety Layer
Afferent evidence collection, tension assessment, and tri-state management (SAFE/DANGER/SHUTDOWN) to build neural-system-like safety mechanisms ensuring stable operation of agent systems.
Agent Protection
Vagal Brake, Reflex Arc, and Capability Token authorization work together to prevent dangerous actions and provide instant responsive protection.
Multi-Language Stack
Seamless integration of Rust WASM smart contracts, Rust device gateway, and Python planner, supporting complete security lifecycle management from blockchain to edge devices.
Project Components
Modular architecture designed for scalability and interoperability across the entire safety stack
contracts/
