01What Hermes Agent OS Is and How It Works

Hermes Agent OS is a framework that lets you build AI-powered agents without writing any code. You tell the agent what you want it to do in plain English, and it figures out how to do it. In this episode, Julian Goldie shows how to automate a travel agent from scratch using this system.

The framework has four steps: find the task that eats up your time, engineer an agent with one specific job, run it on a real task, and then catch the gaps. Julian explains that done is better than perfect — a running agent at 80% beats a perfect one still being designed. The goal is to build an entire operating system that runs on AI and automates in the background.

02Main Features of Hermes Agent OS

Hermes Agent OS lets you build agents without coding. You can create a skill inside Hermes that you can call anytime, even from Telegram. The system works with free models like Google's Gemini 1.5 Flash and can switch between APIs like Open Router.

  • No coding required — just type what you want the agent to do in plain English.
  • Single-job agents — you give each agent one role, one goal, and the tools it needs.
  • Agent stacks — you can connect multiple agents together for complex workflows (e.g., one agent handles SEO research, another creates content).
  • Skill system — once you build an agent, you save it as a skill for reuse.
  • Works with multiple AI models — you can run the same task in Hermes Agent and Claude to compare results.

03How to Set Up Your First Hermes Agent

  1. Open a terminal window and run Hermes Agent.
  2. Type your task in plain English — for example, “Build an AI travel agent that finds cheap flights for a trip to Manila.”
  3. Give the agent a role (e.g., “travel specialist”) and a goal (e.g., “find the cheapest flight”).
  4. Add the tools the agent needs — in this case, the Amadeus API for flight data.
  5. Let the agent build a project structure and a skill wrapper automatically.
  6. Get the Amadeus API key from the Amadeus website and plug it into the agent.
  7. Test the agent by entering your travel details. It will create a simple mini app hosted locally.

04How to Use Hermes Agent OS: A Real Travel Agent Example

In this episode, Julian builds an AI-powered personal travel agent for a trip to Manila. The user wants to stay exactly nine days between certain travel windows. Julian walks through the process step by step.

First, he opens Hermes Agent and tells it to automate the travel planning workflow. The agent begins to build the backend files, creating a skill wrapper for the travel planner. Julian also runs the same task inside Claude to compare how each approaches the problem.

Once the backend is ready, the agent sets up a simple mini app on a local website where you can enter trip details. You need to get an Amadeus API key to connect to real flight data. After that, the agent can find the cheapest flights and monitor trip details.

05Results and Comparisons Shown in the Episode

Julian shows that both Hermes Agent and Claude can build the travel agent, but they approach it differently. Hermes Agent creates a skill wrapper and a mini app, while Claude builds the files in parallel. The agent runs locally, so no one else has access to it.

Julian emphasizes that the first agent won't be perfect. You need to connect your own API key and test it. Once it works, you can expand to other use cases.

He also points out that a working agent at 80% is better than a perfect one still on paper.

06Tips, Limits and Mistakes to Avoid

Julian shares several important tips from his experience. First, don't wait to ship until the agent is perfect — do it anyway and improve as you go. Second, you can use free models like Google's Gemini 1.5 Flash to keep costs low.

Third, always systemize your processes by creating SOPs (standard operating procedures) so you can reuse them later.

  • Mistake to avoid: thinking you need to learn coding. You don't — just give clear instructions in plain English.
  • Limit: the agent needs an API key for external services (like Amadeus for flights), and you have to get that yourself.
  • Tip: start with one simple task, get it running, then expand to new cases.

07Who Hermes Agent OS Is For and Why It Matters

Hermes Agent OS is for anyone who wants to automate repetitive tasks without hiring a developer or learning to code. Julian says the biggest wins are happening in ordinary fields like travel, real estate, e-commerce, freelancing, and marketing agencies. You can set up your first agent in under 30 minutes.

This matters because AI agents are often seen as only for tech companies, but Julian shows that non-technical people can use them too. The framework helps you build an entire system that runs on AI in the background, saving you hours every week. Whether you're a business owner, freelancer, or just someone with side projects, this system can give you your time back.
