Hello, I'm Tsukuboshi (tsukuboshi0755)!

At DevelopersIO 2026 Tokyo held on October 24, 2026, I gave a talk titled "Key Points of Harness Engineering in AI-Driven Development"!

In this article, I'd like to share the presentation materials!

What is DevelopersIO 2026 Tokyo?

It is a technology conference hosted by Classmethod, and this year marks its 12th edition.
This time, it was held as a tech festival using two of Classmethod's Tokyo offices, featuring a large number of AI and cloud sessions from afternoon to night!

Closing

This time, I introduced the content of my talk about three key points for turning AI "requests" into "mechanisms" through linters, tests, and reviews.
The methods presented are based on my own development experience, and they are not necessarily the only correct approach.
However, I believe that if you find yourself giving the same reminder twice, that's the right time to turn it into a structured mechanism.

Please, once your conversation with AI winds down, try instructing it to configure your linters, tests, and reviews, and grow your own harness!

That's all from Tsukuboshi (tsukuboshi0755)!
