Claude writes the minutes: a summary, decisions, action items with owners and due dates, and open questions. **Code then checks every item against the transcript**, and the result goes to Google Sheets and Slack.\n\n### How it works\n1. A form collects the title, date, attendees and transcript. A meeting already in the Minutes tab is skipped.\n2. Claude must give, for every item, a quote copied from the transcript.\n3. **Code checks:** the quote must be in the transcript, the owner must be an attendee and named near the quote, numbers must be in the transcript, and words like \"by Friday\" or 来週の金曜 become a real date from the meeting date. An item that fails is saved as **Needs review** with the reason, never dropped.\n4. One row per meeting (Minutes tab), one row per item (Items tab), and a Slack summary with ⚠ on doubtful items.\n\n### Setup\n1. Create a blank Google Sheet, paste its ID in **Spreadsheet ID**, run the **Run once** branch (adds the Minutes and Items tabs), then select the sheet in the Google Sheets nodes.\n2. Credentials: Google Sheets OAuth2, Anthropic, Slack. Pick a channel in the two Slack nodes (the app must be in the channel).\n3. Publish, open the form URL, paste a transcript.\n\n### Customization\nSet the output language, the quote length and the transcript limits in **Config**.
