        "content": "## Write a root cause analysis report\nTurn your rough notes on a problem that happened into a root cause analysis report that separates what happened from direct causes, contributing factors and possible root causes, with each cause tied to evidence in your notes and a fix for each possible root cause.\n\n**How to use**\n1. Open **Chat model** and pick your own credential. To use another AI service, delete that node, add the service's chat model node, and connect it to the Model plug under every step and AI check.\n2. Open **Inputs** and paste your material into each field. Examples are filled in so you can try it first.\n3. Click **Execute workflow**.\n4. Open **Result** to read the answer, anything flagged, and the checks left for you.\n\n**Checks**\n- Check 1 (a plain rule, run automatically with no AI): Each quote in the Event (quote) column appears in the your notes on the problem, with shortened fragments in the same order. If it fails: try once more, then flag.\n- Check 2 (a plain rule, run automatically with no AI): Every row of the table has one of \"direct cause\", \"contributing factor\", \"possible root cause\", \"unproven\" or \"none\" in the Level column. If it fails: try once more, then flag.\n- Check 3 (a plain rule, run automatically with no AI): Every number in the answer also appears somewhere in at least one of \"your notes on the problem\"; this does not check what each number means. If it fails: try once more, then flag.\n- Check 4 (a plain rule, run automatically with no AI): The answer contains the text fragment \"Check this report with the people who were there before you share it.\" (including inside a longer word). If it fails: try once more, then flag.\n- Check 5 (a second AI prompt answers pass or fail): Read the report. Does any line name a person, or say a person should have known or tried harder, as a cause? Answer FAIL and quote each place where one does. Wording about a role, a form, a rule or a tool is fine. If it fails: try once more, then flag.\n- Check 6 (a second AI prompt answers pass or fail): Look at the rows below marked possible root cause. Does each one have a real quote in the Support column, not none in the notes? Answer FAIL and quote each one that has no support. If it fails: try once more, then flag.\n- Check 7 (a second AI prompt answers pass or fail): Count the possible root causes in the report and the fixes under Fixes. Is there one fix for each? Answer FAIL and quote each possible root cause that has no fix. If it fails: try once more, then flag.\n- Check 8 (you check it by hand): Ask someone who was there to read the report and say whether the events match what they remember. Check that every possible root cause is one you could test, and that no fix is promised that your team has not agreed to. If it goes outside your organization, have your manager or legal lead read it first. A root cause is only confirmed when people have checked it. If it fails: flag it and carry on.\n\nFrom Logic Lab (logiclabhq.com). Free to use and adapt, with credit.",
