 # Holt die komplette Logik zentral aus user2595/ci-ai (reusable workflows) — keine
 # Skripte/Workflows ins Repo kopieren. Update der Logik passiert einmal in ci-ai.
 #
+# Features:
+#   - security  : Gitleaks + Trivy, hart blockierend (push/PR)
+#   - review    : KI-PR-Review + Summary (PR)
+#   - commands  : Slash-Commands im Kommentar — `/gen-tests`, `/summarize`
+#
 # Voraussetzungen (einmalig zentral eingerichtet):
 #   1. Runner instanzweit registriert (Label `eulernest`)
 #   2. anonymer Clone für public Repos erlaubt
