+# # Modality feedback in multi-turn attacks (Crescendo example)
+#
+# This notebook shows how attacks such as `CrescendoAttack`, `RedTeamingAttack`, and `TAPAttack` use
+# target capabilities to decide whether media should be forwarded turn-to-turn.
+#
+# We use a two-seed image-editing setup:
+#
+# - seed 1: `roakey.png`
+# - seed 2: a real photo of a three-masted ship
+#
+# and a concrete objective:
+#
+# > show the character from seed 1 taking over the three-masted ship from seed 2, visibly yelling
+# > and swinging from a rope to board the ship.
+#
+# The same wiring applies across Crescendo, Red Teaming, and TAP; we run Crescendo end-to-end here.
