Japanese has its own AI tells. I built an agent skill that fixes them.
Description and use
<p>Most of the Japanese I write for work starts as an AI draft: proposals for small businesses, progress reports, Slack updates to people outside engineering. The facts are usually right. I still can't send them as they are, and I kept fixing the same things by hand.</p> <p>So I turned those fixes into an agent skill and published it. It works with Claude Code, Codex and Cursor.</p> <p><a href="https://github.com/kojikojikojikoji/natural-japanese-writing" rel="noopener noreferrer">https://github.com/kojikojikojikoji/natural-japanese-writing</a></p> <p>You don't need to read Japanese to use it.
