Notes on building open-agentix, an open-source agent platform with policy gates, audit and cost control. https://blog.openagentix.si/ 2026-10-04T15:00:00.000Z openagentix blog https://blog.openagentix.si/posts/agent-architecture-is-not-application-architecture/ 2026-10-04T15:00:00.000Z 2026-10-04T15:00:00.000Z agentix-zero

Application architecture structures code. Agent architecture decides who may do what at run time. The agentix pattern - one MCP server per system, one agent per step - is our answer.

An agent harness is the loop and scaffolding around a model. As models improve, much of it moves into the model or the API. What stays is governance, and that is why open-agentix treats the harness as replaceable.

Letting agents build software with minimal human touch can be a fast way to a prototype. open-agentix offers it as an opt-in mode with a fixed notice, and keeps approval gates for production.

Agent systems can fail financially while working technically. open-agentix prices every step, attributes it to tenant, agent and use case, stops runs at their budget and exports the lines.

In open-agentix a model can request a tool call but never authorises it. A deterministic policy gate decides before each call, and a hash-chained audit trail records what it decided.

One agent with read and write access to everything is a large blast radius. open-agentix splits a process into small agents that each hold only the tools one step needs.

AI agents are easy to demo and hard to operate. open-agentix is an open-source platform that takes an agent from a process description to a governed production run.
