I’ve finally found the direction for my blog. It took longer than I expected (much longer, honestly). I’ve consistently had the desire to write, but the answers to why I write, what I should write, and how I should keep it going were always blurry. So there were always beginnings, short bursts of enthusiasm, and then long pauses. Now, after enough trial and error, I’m starting to see a shape that feels like “this might actually last.”

As a software engineer and an AI engineer, I often think about what I should care about in the long run, what goals I should set, and what kind of mindset I should live with. In times like these—when technology changes quickly—it’s natural for plans to shake. But just because it’s natural doesn’t mean I can brush it off lightly. When my direction shakes, my actions change, and when my actions change, the results change.

A feature called Claude Cowork has been released. (It’s been out for a while, but I only just got around to trying it.) I’ll ramble on a bit more below, but for those short on time, here’s a quick summary:
While working with Cursor (an AI-powered code editor), I started wondering whether the same approach could be applied to tasks beyond software development. However, since Cursor is inherently a software development tool, there was a real barrier to using it for non-dev work. So I had been quietly hoping that ChatGPT or Claude would release some kind of application better suited for non-development tasks—and it turns out Claude shipped a feature called Cowork first.
March 11, 2026These days, it’s harder to find someone in the developer community who doesn’t know about OpenClaw than someone who does. It has surpassed 300,000 GitHub stars, and 2 million people visited in the first week alone. X (Twitter), Discord, Reddit—everywhere you look, it’s all about OpenClaw.
In a nutshell, OpenClaw is a personal AI agent platform that runs on your own machine. It started in November 2025 as a weekend project called “ClawdBot”, went through a trademark issue, passed through “Moltbot”, and settled on OpenClaw in January 2026. The meaning behind the name is simple: “Claw” represents the project’s lobster mascot (🦞), and “Open” stands for open source and community-driven development.

As AI has advanced rapidly, my state of mind has also swung quite a bit over the past few years.
Before AI seriously entered the way we work, I was a very confident developer. I liked development itself, and I enjoyed learning new things. I saw myself less as a specialist and more as a generalist and full-stack engineer, and I believed my strengths were in structuring ideas logically and communicating clearly.

I actively use AI agents (Cursor, Claude Code, etc.) across multiple projects. At first, having an agent write code was impressive enough on its own. But as I integrated them more deeply into real projects, I kept running into recurring problems.
The root cause of these problems wasn’t a lack of agent intelligence — it was that the environment surrounding the agent was not properly set up. As 2026 arrived, this concern spread across the industry and began to be systematized under the name “harness engineering.”

These days, a lot of people are saying good things about Codex. But the moment you try to actually use it, things get confusing.
Codex CLI?Codex App?Cursor?Codex model inside Cursor chat?Claude Code as a plugin?I had the same questions, so I went through the official documentation and organized what I found. I tried to write this in a way that even beginners, or people who do not usually work with coding tools, can follow comfortably.

The boundaries between roles inside companies are getting blurry very quickly. In the past, planners planned, designers designed screens, and developers wrote code. The roles were not perfect, but they were relatively clear. Now AI tools and agent-based workflows are making it common for one person to take on work that used to be split across several roles.

Lately I’ve been hearing a lot about Hermes Agent. The most compelling example came directly from a teammate. They told me they had already connected Hermes to our company Slack and built an environment where the team could handle data lookups, task requests, and Q&A with a simple @Hermes message. That was enough to make me want to understand it properly, so I spent a single day doing all three of the following:
