Hermes Agent
Hermes Agent
Tired of AI assistants that forget everything after each conversation? Hermes Agent remembers past interactions and gets better over time. With ~14,000 stars on GitHub, it’s a popular open-source solution. The diagram below shows the main path.
I am looking at Hermes Agent as an engineering system. I care about where work moves, where state is saved, and what happens when one part fails.
System overview
The names change from project to project. The design questions do not. The diagram keeps the main path small so the handoffs are easy to see.

Main components
- Self-improving learning loop creates new skills from experience and gets better over time.
- Multi-level memory system remembers past conversations and can search through them.
- Cross-platform messaging works with Telegram, Discord, Slack, WhatsApp, Signal, and Email.
- Flexible terminal backends run locally, in Docker, SSH, or cloud environments.
Design questions
Before using a system like this with a real team, I would ask:
- Where is state saved? What happens after a restart?
- Which calls are safe to retry? Which ones need an idempotency key or a workflow record?
- What can the agent access? Keep user input, generated code, services, and local credentials in separate trust boundaries.
- How does an operator see a failure instead of finding it later inside a queue or background worker?
The happy path is easy to draw. The hard part is restart, retry, and partial failure.
When it is useful
Use this kind of system when the work repeats and someone needs to inspect what happened. For a one-off task, it may be more machinery than you need.

The project is open source on GitHub. I expanded the original project summary into an engineering note for the Ming Dao School library.
