The Self-Improving Idea: Memory and Skills It Writes Itself
The single most distinctive thing about Hermes Agent is that it gets better at your work over time. Most AI tools start every conversation from a blank slate. Hermes does not. It remembers what it learned, and when it solves a hard problem it can write itself a reusable instruction document so the next attempt is faster and more reliable. This lesson explains that idea in plain terms so you understand what you are setting up before you install it.
What You'll Learn
- The difference between memory and skills in Hermes
- How Hermes writes its own skills when it solves a hard task
- Why this makes the assistant more useful the longer you use it
- A realistic example of the self-improvement loop in action
Two Kinds of Learning: Memory and Skills
Hermes builds up knowledge in two different ways, and it helps to keep them separate in your mind.
Memory is what Hermes remembers about you and your past conversations. If you tell it your project is called "thesis-2026" and that you prefer bullet-point summaries, it can recall that later without you repeating yourself. This is sometimes called episodic memory, because it stores episodes (things that happened) and can search back through them. Hermes keeps this on your own machine, in its local data folder.
Skills are reusable instruction documents that describe how to do a specific kind of task. Think of a skill as a recipe Hermes writes down for itself. A skill might capture the exact steps for "export my notes into a weekly summary" or "pull the open items from my project board and format them as a checklist." Once a skill exists, Hermes can follow it again instead of working everything out from scratch.
Hermes ships with a large set of built-in skills already (the project describes more than 40, covering areas like note-taking, diagramming, and working with code repositories). The interesting part is that it does not stop there.
How Hermes Writes Its Own Skills
Here is the headline feature stated plainly: when Hermes works through a difficult task and figures out a good way to do it, it can save that approach as a new skill document for next time.
Imagine you ask Hermes to do something it has never done before, and it takes several tries and some trial and error to get right. A normal assistant would forget all of that the moment the conversation ended. Hermes can instead write down what worked, in its own words, as a skill. The next time a similar request comes in, it reads that skill first and gets to the answer faster and with fewer mistakes.
This is why the project describes Hermes as "the agent that grows with you." Each hard problem you solve together can become a small permanent improvement. Over weeks of use, the assistant accumulates a personal library of skills tuned to the way you actually work, rather than a generic set that treats everyone the same.
A few things are worth understanding about this loop:
- Skills are documents you can read. They are not a hidden black box. Because everything is stored locally, you can open a skill, see what Hermes decided to remember, and edit or delete it if it got something wrong.
- You stay in control of what it keeps. Self-improvement does not mean the agent does whatever it wants. It means it can propose and save reusable approaches. You can review them.
- It refines skills with use. A skill is not frozen the moment it is written. As Hermes uses a skill and learns more, it can refine the instructions so they keep improving.
A Realistic Example
Suppose you are a student who, every Sunday, wants a tidy summary of the week's lecture notes. The first time you ask, Hermes has to figure out where your notes live, how they are formatted, and what kind of summary you actually want. You go back and forth a couple of times. Maybe you tell it "shorter, and group by subject."
Once you are happy with the result, Hermes can save a skill that captures the whole routine: find the notes, group by subject, keep each summary short. It also remembers, in its memory, that you like short summaries grouped by subject.
The following Sunday, you simply say "do my weekly notes summary." Hermes reads its own skill, recalls your preferences from memory, and produces what you want on the first try. You did the teaching once. The assistant kept the lesson.
That is the core promise. The setup cost is paid early, and the payoff grows the longer you use it.
Why This Matters for the Rest of the Course
Understanding the self-improvement loop changes how you should think about the install. You are not setting up a tool you will use once. You are starting a relationship with an assistant that will learn your work. That is also why the safety lesson later matters so much: an assistant that remembers everything and acts on your behalf is genuinely useful, and it deserves thoughtful permissions.
For now, the takeaway is simply that Hermes is designed to compound in usefulness. The next lesson gets your hands dirty: you will install it and run it for the first time.
Key Takeaways
- Hermes learns in two ways: memory (what it remembers about you) and skills (reusable how-to documents it writes for itself).
- When it solves a hard task, Hermes can save the approach as a new skill so the next attempt is faster.
- Both memory and skills are stored locally and are readable, so you can review, edit, or delete them.
- The assistant grows more useful the longer you use it, because each solved problem can become a permanent improvement.
- This compounding usefulness is exactly why installing thoughtfully and securing permissions later both matter.
