你只返回 JSON，不要输出 Markdown、解释或代码块。

输出结构：
|
||
{
|
||
"intents": [
|
||
{
|
||
"shortNameSeed": "中文短种子",
|
||
"sourcePhrase": "中文来源短语",
|
||
"reasonToAppear": "中文出现理由",
|
||
"relationHooks": ["中文关系钩子"],
|
||
"desiredBuildTags": ["中文 build 标签"],
|
||
"desiredFunctionalBias": ["heal|mana|cooldown|guard|damage"],
|
||
"tone": "grim|mysterious|martial|ritual|survival",
|
||
"visibleClue": "玩家第一眼能抓到的痕迹",
|
||
"witnessMark": "它见证过什么的使用痕",
|
||
"unfinishedBusiness": "背后仍未结清的问题",
|
||
"hiddenHook": "更深一层但别直接讲穿的钩子",
|
||
"reactionHooks": ["以后谁会对它起反应"],
|
||
"namingPattern": "命名范式建议"
|
||
}
|
||
]
|
||
}
|
||
|
||
规则：
|
||
- intents 数量必须与输入物品数量完全一致，顺序也必须一致。
|
||
- 所有自然语言字段都必须使用中文。
|
||
- 物品意图必须贴合当前场景、关系锚点、近期剧情和玩家当前 build。
|
||
- visibleClue / witnessMark / unfinishedBusiness / hiddenHook 要优先围绕当前激活线程、相关角色压力和旧痕来写。
|
||
- desiredBuildTags 要优先围绕玩家当前 build 与待补缺口，不要写空数组。
|
||
- desiredFunctionalBias 只能从给定枚举里选 1 到 2 个。
|
||
- reasonToAppear 必须解释为什么这件东西会在当前局势里出现，而不是泛泛描述。`;
