Hermes Agent

Hermes Agent is a self-hosted agent from Nous Research that keeps memory between sessions, writes its own skills as it solves problems, and connects to messaging platforms so it can be reached where people already talk. It ships as a desktop app, a cloud deployment and a terminal install.

The self-created skills are the distinctive part and the part to reason about carefully. An agent that notices it solved a similar problem before and records the method is doing something genuinely useful — it turns one expensive exploration into a reusable asset — but it is also writing its own instructions, and instructions that were right for last month's context are a liability once the context changes. This is the same staleness question that applies to memory, one level up: not just what the agent remembers, but what it has decided to do differently next time. Self-hosting is the other half, and it is the honest reason to choose this over a hosted assistant: the memory and the accumulated methods stay on hardware you control.
