+    This summary will be read by an AI coding agent (Claude Code), not a human.
+    Be direct and structured. Use a changelog with emojis: ✨ Added, 🔧 Changed,
+    🐛 Fixed, 🗑️ Removed, ⚠️ Breaking, 🔒 Security. After the changelog, list
+    any concerns or issues the agent should address as a flat bullet list — no
+    prose, no praise, no context the agent already knows from the diff.
