Agents becoming even more human-like (Opus 5):
”… Where I went wrong
You asked for the refactor to be a separate PR: I heard "separate commit" and built one branch with two commits. …”
They hear things now ...
A couple of days ago I released a new feature to the Python tools for the Polylith Architecture:
Adding the possibility to find related source code (aka bricks) for changed tests.
This new feature adds an option to find the corresponding brick according to the folder structure, regardless if the code was imported in the test or not. This is useful fo extract bricks that are related (or "owners") of the tests. The idea is from a user of Polylith!

The more agentic engineering I do, the more Emacs I use. I've even begun using org-mode for presentations/slides. Using Eca for the agentic experience works really well, especially when switching between providers (anthropic, gemini, mistral).
It also takes advantage of being in an editor, and checks code diagnostics via the editor tooling (such as LSP, linting etc.)
Eca isn’t only for emacs, and is available for most IDEs out there. It also is Open Source!
Many great games and fantastic ⚽️performances, but each time the fifa logo pops up we are reminded of that it’s all about the money and the power. The corruption in these type of events is well known and goes way back, but what we see these days … is that a new low?
What’s next, will they call in the referee from France vs Paraguay for the upcoming US game? No disrespect of the players themselves though.
Still thinking about the ⚽️ from last night. Argentina and Kap Verde, what a great match! So far, my favorite of the World Cup.
There’s so much more good games to come, I guess I’ll sleep properly again sometime in late July.
At work: agentic engineering.
At home (open source): writing code by hand.
I see it as the best of two worlds. And to keep my skills, not only the agent skills, intact and constantly improving.
Refactoring with AI?
With Agentic Engineering there's an opportunity to refactor legacy code, but this aspect of AI isn't that that much talked about and seems to be overlooked by teams out there.
I have added agent skills to the Polylith for Python tool, that are focused on that specific thing: migrating and refactoring an entire Python repo. 😅

I'm not too worried about any Brain rot caused by using too much AI, mainly becase I'm an :emacs: user.
With Emacs, it is by design a constant Brain Trainer. Like now, when the command for how to copy an entire buffer had disappeared from my memory (yes, we don't refer to files as something silly as "files" here).
So. I forced myself to focus, and also try to get into a Zen Flow state by thinking about the wise words from Bruce Lee:
"- Don't think! Feel."
The command: C-x h
Lagom, allemansrätt and fika: three words I really like and that also summarizes Sweden pretty well!
🤖 Adding Agent Skills to Polylith 🤖
The skills will show your agent how to use the Python tool, and will add knowledge about the Polylith Architecture in general.
I think this will be helpful for teams that practice Agentic Engineering.
I have updated the docs here:

I love music, and always look for new sounds. My preferred styles are different variations of jazz, but I listen a lot to soul, funk, house, reggae and … the list can go on. Live music is what gives me new energy.
Lately, I have felt the need to verify new stuff I find at Spotify by looking up the (often anonymous) artists.
“- is this human made or AI?”
Feels kind of dystopian. I don’t mind AI-created apps or products - you know, business stuff. But music? Art. No. Just no.
I just released a new feature in the Python tools for the Polylith Architecture:
Validate the interfaces for the bricks in the Polylith workspace.
This feature is useful for teams that develop code with clear and explicit boundaries, and want to be able to validate those in their Monorepo.
Announcement here:

RE: @pyconsweden@fosstodon.org
Feels like a long time ago. When coding wasn’t between Human and Prompt, but between the Human and the interactive REPL.
I have released a tiny update to the python-hiccup library. I'm using it at work and found that the number of downloads has 📈. Hiccup is an alternative to templating/jinja.
This kind of programmatic approach to markup with Python data structures is a good fit for Agentic development too.
Example, using HTML:
python-hiccup equivalent:
["div", ["span", ["strong", "Hello world"]]]
Oh, so that's why they named it Fable?
It seems like Claude Code sometimes switches from Fable to Opus for coding tasks.
This reminds me of a classic TV show for kids, way back: I fablernas värld.
A human as an owl. Opus as a Fable.
Practice what you Preach
(or rather, what I Preach)
One of the features that I have added during 2026 to the Open Source tool that I maintain, is the possibility to inspect the coupling between individual parts of the code in a Python Monorepo.
Then I found that I had too much of that in the source code of the tooling itself, so I fixed it and wrote a short post about it. Because ...
