This workflow looks for those things and posts a short report in Slack. It uses no AI.\n\n### How it works\n1. **Every morning**, one cheap and free call per service (Chatwork, LINE, Slack, Anthropic, Gemini, Google Sheets, Gmail) tests whether each credential still works. A 401 means invalid or expired; n8n's own \"needs to be reconnected\" is shown as it is. Dates you keep by hand (API key expiry, domain renewal) are flagged 14 days ahead. It stays quiet unless something is wrong, plus one \"all fine\" on Mondays.\n2. **Every Monday**, it reads your workflows and executions through the n8n API: executions per workflow (24 hours, 7 days, 30 days), failures, sudden increases, a monthly projection, and the most AI calls those executions could make.\n3. It audits the workflow list: published without an error workflow, published webhooks without authentication, secret-looking text inside nodes, published workflows that never run.\n\n### Setup\n1. Create an n8n API key with read-only scopes (workflow and execution: list and read) and an **n8n API** credential (Base URL `http://<your n8n>/api/v1`).\n2. In the check nodes you use, select your credentials. **Delete the checks you do not use.**\n3. Select your Slack channel in the two Slack nodes.\n4. Edit the expiry list in **Credential settings**, then publish.\n\n### Customization\nTo add a service, copy a Check node and add its name to the list in **Judge the credentials**. Set your monthly execution quota in **Usage settings**.",
