I'm Kenji Sakuramoto. I run ｋｅｎｓａｕｒｕｓ LLC, a studio in Shibuya, Tokyo, founded in June 2025, and I run more than ten repos on my own. Most of what I've shipped started with a problem in my own life.

Agents stop halfway. Sometimes they report "done" when it isn't. With one person and more than ten repos, I needed the same steps and the same definition of done everywhere, so I wrote them down as playbooks.

The part that matters most: the agent that did the work doesn't get to say it's finished. A separate reviewer, instructed to work read-only, compares the plan, the diff and freshly re-run checks, and answers PASS, CONTINUE or BLOCKED. If the evidence is missing, the answer is CONTINUE.

Bug reports work the same way. Reports from my bug-reporting tool, Mushi Mushi, feed fix runs that end in a pull request, and I merge each one by hand.

With AI, one person can now build a lot. If more people build for themselves and for the people around them, clearing small everyday chores one at a time, life gets a little easier for everyone. I'd like to be one of them.
