  • Running Hermes Agent in the Cloud Safely: A Reader's Guide to Their Trust Model
    3 projects | dev.to | 10 Jun 2026
    NousResearch publishes a detailed security policy for Hermes Agent. It is unusually clear about what the project treats as load-bearing and what it does not. If you operate Hermes in the cloud, read it first; this post is the operator-friendly companion, not a replacement.
  • Hermes Agent – Open-Source AI Agent with Persistent Memory
    3 projects | news.ycombinator.com | 8 Jun 2026
    OpenCode seemed perfectly workable as a programming assistant. As personal assistants, they all fall short. It's too difficult to really shape their output.

    I was briefly impressed with OpenClaw a few times, but ultimately was turned off by not being able to get the models to stop being so damnably verbose. I thought I made progress for a while by having it tweak its soul, iterate, switch models, iterate, switch models, fuse the results, iterate... but ultimately it's all forgotten early in each session. And then one day it killed itself by rebuilding the container it was inside.

    Hermes apparently has some plagiarism issues they're trying to cover up [0] and I was deeply unimpressed with their janky, flickery CLI that force-enables a bulky obnoxious header.

    Nanoclaw and nanobot seemed fine, but not notably different. There were some common bugs and glitches that caused some minor data loss while configuring nanobot. After that I just deciding to start hacking my own together.

    What I really want in a harness is being able to actually control and rewrite the entire context window, like Zed's Text Threads before they obnoxiously and inexplicably removed what, to me, was their most powerful and distinguishing feature.

  • Hermes Agent's skill trust model is a four-repo allowlist
    1 project | dev.to | 6 Jun 2026
    I've opened a design discussion to argue this out before anyone writes a line of it, because a surprise PR to a security-sensitive module is the wrong way to start. Feedback from people who've thought about supply-chain trust is what I appreciate.

  • Hermes Agent Burned 603M Tokens Behind My Back — I Cut Background Costs by Up to 125x
    2 projects | dev.to | 1 Jun 2026
    I opened my Hermes Agent logs and found something I did not know existed: an auxiliary: block with twelve background tasks. Compression, web extraction, vision, session search, skills matching — all running silently every time I typed a message. Every task was set to provider: auto. And because I had no API keys for the fallback chain, every one silently fell back to kimi-k2.6, my one-trillion-parameter main model.

    Excellent article, and I fully agree.

    I came to the same realization a while ago and started building an agent runtime designed to ensure all (I/O) effects are capability bound and validated by policies, while also allowing the agent to modify itself.

    A low(er)-level agent runtime: https://github.com/smartcomputer-ai/agent-os/

    AgentOS is a lisp-machine inspired runtime where agents can safely propose, simulate, and apply changes to their own code, policies, and workflows, all under governance, with full audit trails. Every external action produces a signed receipt. Every state change is replayable from an event log.

    Agents have agency: they do stuff. The way the do it is by calling code or writing code and then executing it. They need some retrieval system too (often called memory) that selects the relevant possible actions for a current context.

    I wrote this article recently that outlines what a system needs to run agents: https://github.com/lukebuehler/agent-os/blob/main/docs/artic...
