It can run manually or on a Monday morning schedule, loads configurable exclusions and limits, retrieves published workflows, checks for missing error workflow settings, then posts a Slack digest only when there is something to report.\n\n### Setup steps\n\n- Configure the n8n credential used by the \"Get Published Workflows\" node so it can list workflows from the target n8n instance.\n- Update the \"Configuration\" node with the correct n8nBaseUrl, excludedTags, excludedWorkflowIds, and maxWorkflowsListed values.\n- Configure the Slack credential and target channel in the \"Send Slack Digest\" node.\n- Review or adjust the schedule in \"Every Monday Morning\" if the audit should run at a different cadence.\n\n### Customization\n\nAdjust the exclusion lists to ignore known-safe workflows or tags, and edit the Slack message formatting code if you want a different digest layout or severity wording.",
