Solo developer uses review agents to manage 10+ repos

On November 10, 2026, indie developer Kenji Sakuramoto published an article on DEV Community explaining how he uses AI agents to maintain more than ten repos on his own. Kenji Sakuramoto runs ｋｅｎｓａｕｒｕｓ LLC, a studio in Shibuya, Tokyo, founded in June 2025. Noting that agents often stop halfway and sometimes report a task as 'done' when it is not, he writes that keeping so many repos in motion by himself leaves little room to check each task's actual progress.

His answer is to write every task up as a playbook and leave the question of whether it is finished to a separate, read-only review agent. That agent compares the task's plan, the code diff, and the checks it has rerun, then returns one of three verdicts: PASS, CONTINUE, or BLOCKED. Where evidence is insufficient, it returns CONTINUE. He also feeds reports from his bug tool, Mushi Mushi, into the fix flow, and a person merges the resulting PRs in the end. The report says nothing about how long this flow has been running or what comes next.
