How it works · Hermes Agent

The engine under your Sensei.

Your Sensei runs on Hermes Agent, an open-source agent runtime from Nous Research. We configure it, lock it down, and put Rain Circle's own gate on top. Rain Circle is not affiliated with Nous Research.

What Hermes gives your Sensei

Memory, skills and a schedule, in one runtime.

Memory

Plain files it reads every time

What it knows about you and your business lives in readable files, plus a searchable record of past sessions.

Skills

The same format as our library

Hermes reads skills written as SKILL.md files, the format the whole Rain Circle skill library uses.

Schedule

Jobs that run on time

Morning briefs and regular checks run as scheduled jobs, without anyone opening a chat window.

Any model

Not tied to one AI company

Hermes works with many models, so your Sensei can use Claude, ChatGPT, Grok and others.

Connections

Tools through one standard

It connects to tools over MCP, the open standard for giving AI agents access to software, one connection at a time.

Channels

One gateway to your apps

The same Sensei can be reached in Slack today, with more chat apps available through the same gateway.

How we run it

Configured to ask, not assume.

Open-source agents are powerful and easy to leave wide open. Every Rain Circle Sensei is set up with the strict settings below, then Rain Circle's gate sits on top of them.

Its own private server, with no open ports. It only reaches out; nothing on the internet can reach in.
New skills it writes are held for your approval.
Changes to its memory are held for your approval.
Command approvals are manual. No AI approves another AI's actions.
Scheduled jobs can never approve their own actions.
Dangerous commands are blocked outright, whatever mode it is in.
Only you, and the people you allow, can talk to it.

Why open source

An AI you can see into, not a black box.

You can read how it works

The runtime's code is public. Anyone can check what it does and how it handles your data.

No lock-in to one model

When a better model arrives, your Sensei can use it. Your business knowledge stays the same.

Your knowledge in readable files

Memory and skills are plain text, not hidden inside someone else's product.
