&lt;p>&lt;a href="https://chouseisan.com">Chouseisan (調整さん)&lt;/a> is a popular Japanese scheduling tool — but it has no public API, and entering attendance for events with 40+ candidate slots gets tedious. So I built a small CLI that automates the entry with Playwright. The decision part — figuring out which slots are &lt;code>◯&lt;/code> / &lt;code>△&lt;/code> / &lt;code>×&lt;/code> based on my Google Calendar — is delegated to Claude Code via the &lt;a href="https://www.anthropic.com/">claude.ai Google Calendar MCP&lt;/a>.&lt;/p></description></item></channel></rss>
