+            Use the CI tools to list the latest workflow runs for this pull request
+            and download the logs of every failed job. If no workflows failed, say
+            so and stop.
+

+            the base branch of the PR.
+
+            For each failed workflow, find out what failed and search the root cause(s).
+            Devise at least one possible resolution for each root cause.
+
+            Report your findings as PR comment. Start your message with "# Automated
+            CI failure analysis". Then add one section per root cause with:
+
+            - The affected workflows
+            - Evidence from the logs
+            - The fix proposal(s)

+            workflows that did not fail.
+
+            Use Markdown links for anything that can be navigated to on GitHub
