+"""Compare the two sub-agent context-passing strategies (实验 4-4「对比效果」).
+
+Spawns a sub-agent under BOTH `minimal` and `llm_generated` strategies on the
+SAME task and prints the difference (context tokens handed off, extra
+preparation cost, whether private data leaked, and each sub-agent's result).
