Bug reports from his tool Mushi Mushi feed automated fix runs that end in pull requests he merges by hand. Sakuramoto says the setup lets one person ship far more, and he frames it as building tools for everyday chores.", "body_md": "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.\n\nAgents 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.\n\nThe 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.\n\nBug 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.\n\nWith 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.\n\nThe longer version is on [the maker page](https://kensaur.us/notes/maker/en/?utm_source=devto&utm_medium=post&utm_campaign=gtm-2026q4&utm_content=maker).\n\n*An AI assistant drafted this post from my own answers, and it was fact-checked before publishing.
