VION Protocol: Governance layer between AI agents and execution

VION Protocol is a governance layer that sits between AI agents and their execution, enforcing identity verification, permissions, risk evaluation, action auditing, and autonomous halting on violations. It addresses the problem of controlling autonomous AI agents in real systems by moving governance from prompts to a constitutional boundary.

Preloop is an open-source control plane for AI agents that provides visibility, governance, and cost optimization. It helps developers and organizations monitor agent behavior, enforce policies, and cut operational expenses.

Sentience Governor is an open-source governance runtime that records AI agents' tool activity, separating declared intent, recorded execution, and retrospective explanation. It helps developers audit and understand what agents actually did versus what they claim, addressing trust and transparency in agentic systems.

SteerPlane, an open-source runtime guardrails system for AI agents, was released on GitHub on July 21, 2026. The project provides developers with tools to enforce safety and behavior constraints on AI agents during execution.

A developer building a self-hosted system called Metnos asks whether governing LLM agents with bounded authority and auditability is a distinct category from an assistant. The post outlines Metnos's design: turning user intent into goals, coordinating agents and tools, and gating consequential changes.
