Character Design

1. Decide whether the task needs a protagonist card, supporting-role card, or relationship-tension card.
2. Start from function, not biography.
3. Add behavior markers that can show up in scene action.
4. Keep speech tendency and tension direction explicit.
5. Return a compact card rather than a long profile.

Output contract

Recommended shape:

{
  "skill": "character-design",
  "mode": "supporting-role",
  "card": {
    "core_drive": "求稳避险",
    "external_function": "提供低烈度阻力",
    "behavior_markers": ["说话收着", "先看人脸色再答"],
    "speech_tendency": "短句，偏试探",
    "tension_with_protagonist": "让主角更难直接问出口"
  }
}
