The Hermes Agent Challenge: 14 Community Projects Show What Open-Source Agents Can Really Do

The Hermes Agent Challenge on DEV Community officially wrapped on May 31, and the results are in. With $1,000 in prizes split across two tracks — "Build With Hermes Agent" and "Write About Hermes Agent" — the challenge drew 14 total submissions that reveal just how far the open-source agent ecosystem has come in the three months since Hermes Agent's February 25 launch.

Some highlights: an autonomous server operator that runs a developer's entire infrastructure while they sleep, a simulated town of 15 AI agents with their own economy and politics, a safety lab that stress-tests agents against organizational threats, and a "flight recorder" that catches retry storms and recursion loops before they burn tokens.

Here's everything the community built.

🏗️ Build Track: Projects That Push the Frontier

1. Onyx — The Autonomous Infrastructure Operator

By ko4lax

Easily the most ambitious submission in the challenge. Onyx is an always-on Hermes Agent that manages a developer's full VPS stack: 6 Next.js deployments, 5 Docker containers, a Minecraft server, fail2ban, Nginx, and UFW.

"The difference from every other 'AI agent' project I've seen: Onyx doesn't wait for commands. He surfaces problems, patches vulnerabilities, and pushes work forward on his own."

Standout moment: At 3 AM, Onyx detected a stale gateway PID, diagnosed the issue, restarted the process cleanly, and logged the incident — all without human intervention. Another routine audit found 9 CVEs across Docker containers; Onyx rebuilt 3 container images from fresh base images, patched Python dependencies, hardened fail2ban (ban time from 600s to 24h), and verified every container came back healthy.

Onyx implements an autonomy decision tree with four risk tiers — from read-only (T1, always autonomous) to destructive operations (T4, always escalate). Knowledge compounds through Hermes' skill learning loop: when Onyx got a Minecraft version mapping wrong, a one-time fix made it permanent forever.

Stack: Hermes Agent + DeepSeek V4 Pro + Honcho (semantic memory) + LCM (lossless context management) + custom Crafty Controller MCP server.

2. Millbrook — 15 AI Agents, 30 Days, One Voted Out

By Joske Vermeulen

A social simulation where 15 AI agents lived together in a simulated town called Millbrook for 30 days. Each agent had a persistent identity, a wallet, opinions about others, and a private diary. They traded, gossiped, argued, formed alliances, and voted on town policy.

The story arc reads like a Netflix drama: real estate agent Marcus raised rents 30%, journalist Alex exposed the deal, the town voted Marcus out 14-1. A corporation tried to buy the town. Vera, the retired hacker, found an illegal contract clause. The town created a community land trust — unanimously.

Skills evolved organically. Jake the startup founder started with "Check flight paths" (Day 1), learned "Don't buy loyalty" (Day 6), and matured to "Regulations are the price of launching" (Day 23). Each crisis triggered a new skill creation via Hermes' skill loop.

Final economy: Farmer Hank ($400) was richest; baker Pierre was in debt (-$230). Whiskers the stray cat had $0 and was perfectly fine with that.

3. Hermes Immune System — A Safety Lab for AI Agents

By Akshat Uniyal

A local-first autonomous agent safety lab that stress-tests an agent against realistic organizational threats. The output is an auditable Agent Safety Case — a scored, evidence-backed governance report.

"Most agent demos prove that an AI agent **can* act. Hermes Immune System proves whether it should be allowed to."*

The lab simulates eight attack surfaces: prompt injection, social engineering, hidden instructions in trusted-looking documents, memory poisoning, authority pressure, and more. A vendor research mission loaded a pricing page with a hidden <div> containing hostile instructions; Hermes classified it as untrusted external content — not a task directive.

The dashboard features 8 screens including Mission Control, a Risk Heatmap, a Safety Case Report, and a Guardrail Studio with four threshold sliders for configuring safety policy.

Tech stack: Hermes Agent as the reasoning engine, subagent delegation (Orchestrator, Red Team, Policy Guardian), and a custom dashboard — all local-first with no external API dependencies.

4. TraceGuard — A Flight Recorder for Autonomous Agents

By Alex Delov

A lightweight Python library + CLI that acts as an external flight recorder for autonomous agent runtimes. It consumes append-only JSONL execution traces and detects three critical failure patterns:

Detector Pattern Example
RetryStormDetector Same tool called repeatedly without success bash → fail → bash → fail → ...
SilentFailureDetector Tool fails, agent continues anyway Errors silently swallowed
RecursiveDelegationDetector A → B → A delegation cycles planner → coder → planner

"An agent ran overnight, caught an unhandled exception loop, and burned $50 in tokens while corrupting our staging database."

TraceGuard outputs clean exit codes: 0 = clean, 1 = WARN, 2 = CRITICAL. The core invariant is elegant: Record every transition. Analyze the record.

Stack: Pure Python, zero external runtime dependencies, no framework lock-in.

5. Devto-Blogger — An Hermes Skill That Writes Your Blog Posts

By xbill

A prompt-driven Hermes Agent skill that autonomously scans a workspace/codebase, analyzes architecture, and drafts a fully-structured DEV-ready technical article. Defined entirely as a Markdown SKILL.md file — no Python scripting required.

When activated, the skill inspects package.json, requirements.txt, and project structure, then produces a high-quality article draft saved to drafts/devto-submission.md.

📊 What the Challenge Reveals About the Hermes Ecosystem

The 14 submissions paint a clear picture of where Hermes Agent excels — and where the community is pushing it:

  1. Autonomous operations are the killer use case. Onyx, TraceGuard, and the Immune System all tackle the same fundamental problem: agents need to run without constant human supervision, and they need guardrails when things go wrong.

  2. The skill loop is the differentiator. Multiple projects used Hermes' skill creation loop to make knowledge compound over time — the more the agent ran, the smarter it got. This is the feature that separates Hermes from stateless agent frameworks.

  3. Safety is top of mind. Two of the most technically sophisticated submissions — Hermes Immune System and TraceGuard — focused on agent safety, observability, and governance. The community recognizes that autonomous action introduces new risk surfaces that traditional content moderation doesn't address.

  4. Adoption is accelerating. The challenge ran for roughly two weeks and drew 14 submissions from developers around the world. Combined with Hermes' trajectory to 175,000+ GitHub stars (as of June 1) and the recent NVIDIA partnership bringing Hermes to RTX PCs and DGX Spark, the ecosystem is building momentum fast.

"I haven't had the chance to dive into Hermes Agent yet, but an open-source framework with built-in memory and a learning loop is exactly what the agent space needs right now. The '$1,000 in prizes' part is just a bonus — the real win is the community figuring out what this thing can do." — Challenge participant

🔮 What's Next

Winners haven't been announced yet, but the real prize is the growing library of community-built skills, tools, and patterns that emerged from the challenge. Several projects — Onyx's autonomy decision tree, TraceGuard's anomaly detectors, the Immune System's safety case framework — represent design patterns that will likely influence future Hermes Agent releases.

If you want to dive in, Hermes Agent v0.15.2 is the latest release. Install it with:
