Agents 🤝 IDE tools
The new finding-test skill provides code coverage information to agents, ensuring that tests are created in the correct location and cutting token consumption by ~50%. Available now in the Rider 2026.2 EAP: https://t.co/yztYbs5GNs

JDK 25 is the first release that includes the FFM API and has broad long-term support. Learn how this allows us to avoid the previously slow, brittle, and complex process of using JNI and ByteBuffers.

The most important step in the Spec-Driven Development process with AI agents is the grilling session. Without it, the next steps rely on a lot of implicit assumptions and guessing.

You are welcome.

To complete your code, just dot dot.

Just saying – the best way to request something from your IDE is by starting with dot-dot. For example:

..constructor – generate all arguments or the default constructor without Lombok
..bean – inject a new Spring component
..ai – prompt to ask something in the editor
..live – list applicable live emplates
..imports – organize imports

@intellijidea 2026.1.1 just released and provides the ability of using debugging tools with agents.

It’s amazing - they can run the code in the appropriate run configuration, use existing breakpoints or add new ones as needed, evaluate relevant expressions, ask a human to do something to reproduce the bug, and finally fix it.

Twenty years working on JRuby and delivering hundreds of talks and here's the top five questions I still get:

What is JRuby?
Why should I use it?
Do I need to know Java?
Does it run Rails?

And after my presentation:

Why isn't everyone using this?!

After digging into developer productivity, we learned something surprising: “human in the loop” is mostly just waiting. 💤
🔥 So we fixed it.

Once upon a time, JetBrains IDEs and their plugins had UI freezes… 😱

But fear not — there is the cure. Join me on YouTube soon to figure this out!

Command completion (..) complements existing features. You can still use shortcuts and postfix completion, but now you can also use command completion instead. #IntelliJIDEATips
