How to See and Edit What Your Hermes Agent Remembers
Hermes Agent keeps a memory graph of every skill and memory it has built. Here is how to open it, read it, and delete the parts you no longer need.

Your Hermes agent keeps a record of everything it has learned since the day you created it, and you can look at all of it. The Hermes desktop app has a memory graph: a visual map of every memory and every skill your agent has built, with lines showing how they connect. You can open it in two keystrokes, watch it grow over time, and ask the agent to delete anything that no longer earns its place.
If you want to see it on screen, watch the full walkthrough. The steps below are the same ones I use.
What the Hermes Agent memory graph is
The first time you open it, it looks like a 3D visualization, or like the graph view in Obsidian if you have used that. It is neither. It is the internal memory of your specific agent, drawn as a network.
The graph starts in the center on the day you created the agent and works outward. Mine begins on July 29, 2026. Every day you use the agent, the graph gets a little bigger.
There is a key in the corner. Blue dots are skills. Orange diamonds are core memories. A skill is something the agent has learned how to do; a memory is something it knows about you, your work, or a past conversation. The lines between them show which skills grew out of which memories.
At the top there is a play button. Press it and the graph replays itself from day one, showing the order in which your agent built each memory and skill. It is a good way to understand how the agent got to where it is now.
How to open the memory graph in the Hermes desktop app
You need the Hermes desktop app, logged in. Then:
- Press Ctrl+K. A drop-down opens.
- Choose Memory graph. The full map of your agent's memories and skills appears.
- Alternatively, type backspace, then journey. The memory graph option appears; press Enter.
Both routes open the same view. I use Ctrl+K most of the time.
Reading the graph: how memories turn into skills
The useful part is seeing how things connect. Here is an example from my own agent.
On August 24, 2026 there is a memory called "Percy's YouTube channel". Attached to it are three skills: a YouTube SEO skill, an SEO content operations skill, and a YouTube channel operator skill. I never sat down and wrote those skills. They came out of ongoing conversations where I kept asking the agent how to improve the channel. One memory about what I do led to three skills about how to help me do it.
When you zoom around your own graph you will find the same pattern. A memory about a client, a project, or a recurring task sits in the middle, and the skills the agent built to handle that task branch off it. It is a picture of how the agent thinks about your work.
How to delete a skill or memory from your Hermes agent
The graph also shows you what you no longer need. Zoom in to the center, near the start, and you will find things from when you were first testing. Mine had a skill called "vehicle listing analysis" that I have not used since.
To remove one:
- Click the skill or memory in the graph. Check what it is connected to. This one had no memory tied to it and no other skills linked to it, which makes it safe to remove. If something has several links, be careful, because deleting it can affect the skills that depend on it.
- Go back to the chat and ask the agent plainly. I typed: "Please delete the vehicle listing analysis skill." The agent replied that it had deleted the skill.
- Start a new session. Click the new session button at the top. This refreshes all the files you changed.
- Open the memory graph again. Type backspace, journey, Enter, and scroll to where the skill used to be. It is gone.
Test this first on a skill you do not care about. Once the agent deletes something it is deleted.
You can edit instead of deleting. If a skill is close to right but out of date, ask the agent to change it rather than removing it and starting again.
Why pruning your agent's memory matters
An agent that has been running for months accumulates a lot. Some of it is from experiments you ran once. Some of it describes a version of your business that has since changed. All of it is still in there, and the agent still treats it as true.
Walking through the graph every so often and asking "do I still need this?" keeps the agent accurate and keeps it lean. A smaller, cleaner set of skills and memories means less bloat and more of the agent's attention on the work you actually give it now. This is the same reason I tell people to name one specific job for the agent when they set it up: focus is what makes it useful.
What this means for your business
For a business that runs on a Hermes agent, the memory graph is the audit trail. A few ways to use it:
- Check what the agent believes about your business. If you changed your hours, your pricing, or your process, find the old memory and correct it before the agent repeats it to a customer.
- Clean up after staff changes. If someone who used to work with the agent taught it habits you do not want, you can see those skills and remove them.
- See which skills actually get used. Skills with many connections are doing work. Skills sitting alone at the edge were probably built once and forgotten.
- Understand a new agent quickly. If I set one up for you, the graph is how you can see what it has learned in its first month without reading every conversation.
If you already run one of the setups from my use cases page, open the graph after a few weeks and you will see how the agent has built up the skills around that job.
Keep going
The memory graph is one of the newer features, and I expect it to grow. If you found a use for it that I have not covered, tell me in the comments on the video. For the rest of the setups, the tutorials page has every video, newest first.
If you want an agent set up for your business, with its memory built around your work from day one, get in touch and tell me what you would like it to handle.
FAQ
How do I open the memory graph in Hermes Agent?
In the Hermes desktop app, press Ctrl+K and choose Memory graph. You can also type backspace, then journey, and press Enter.
What do the blue dots and orange diamonds mean?
Blue dots are skills the agent has learned. Orange diamonds are core memories. Lines between them show which skills grew out of which memories.
Can I delete a memory or skill from my Hermes agent?
Yes. Click it in the graph to check what it is linked to, then ask the agent in chat to delete it by name. Start a new session afterwards and the graph will update.
Does deleting a skill affect anything else?
It can if other skills or memories are linked to it. Check the connections in the graph first, and test the process on a skill you do not need.
Why should I prune my agent's memory?
Old experiments and outdated facts stay in the agent's memory until you remove them. Pruning keeps the agent accurate about your business and reduces bloat.
