"""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).

Run:
    export OPENAI_API_KEY=your-openai-api-key        # or OPENROUTER_API_KEY (default model: gpt-5.6-luna)
    python subagent_comparison.py
