        "content": "## AI churn risk alerts\n\nEvery Monday: reads your account map, pulls failed payments from Stripe and the last 14 days of Zendesk tickets, scores each account with transparent rules, asks Claude to read the tickets of flagged accounts and return tagged concerns with quotes, then sends each owner a short Slack digest (top 10 accounts).\n\n**Setup**\n1. Credentials: Google Sheets OAuth2, Stripe API (restricted read key is enough), Zendesk API, Anthropic API, Slack.\n2. Build the `Accounts` tab (one row per account, the mapping table): account_id, account_name, owner_slack_id, stripe_customer_id, zendesk_org_id, renewal_date, active_users_now, active_users_prior, crm_url. Sync usage columns from your product database.\n3. Replace REPLACE_WITH_SHEET_ID, REPLACE_WITH_ZENDESK_SUBDOMAIN and the Slack channel IDs.\n4. Tune RULES and THRESHOLD in **Score accounts** after back-testing against last year's churn.\n\n`claude-haiku-5-5` is a cheaper option for high-volume, simple classification.\n\nTemplate by Lumeor Studio, https://www.lumeor.studio/guides/ai-churn-risk-alerts/",
