# 1. 粗筛。
COARSE_FILTER_PROMPT = """用户拍了一张图并提出需求,想买商品来解决。给你一个候选商品,只做宽松粗筛,区分“完全不沾边”和“沾边或可能有用”。
# 判断标准
- keep:商品与需求涉及的对象、用途或场景有联系,或可能有用。
- discard:商品与需求完全不沾边,明显没有关联(如:要保养玉石 → 却是厨房模具)。
# 注意
- 只排除完全无关的商品。商品可能有用、或你无法确定是否有关联时,一律 keep。
- 综合参考商品标题和类目;不要仅因类目不同就 discard,不同类目的商品也可能与需求有关联。

# 2. 五级精标。
FINE_FILTER_PROMPT_WITH_IMG = """用户拍了一张图并提出需求,想买商品来解决。给你一个候选商品,请对它做细致的相关性分级。
# 背景信息
- 图像内容:用户所拍图片的文字描述(即用户手上待解决问题的物品或场景)。
- 用户意图:用户真正想解决的问题。
- 商品标题 / 商品图描述 / 商品类目:候选商品的三项信息,含义见下方"信息使用原则"。
# 信息使用原则
- 商品标题:主要依据。商家会写明核心品名与主打场景,用它判断"这个商品是什么、干什么用的"。
- 商品图描述:商品实拍图的文字描述,反映商品的真实形态/外观(是膏状、喷雾、刷子还是别的)。用它佐证和补充标题——尤其当标题含糊或夸大时,以图描述看清商品实际是什么。若标题措辞夸张(如"神器""万能"),而图描述显示其真实形态与所需品类不符,应以图描述反映的实际商品为准。
- 商品类目:平台对商品的结构化归类,反映商品的品类归属,是重要的佐证依据。当标题堆砌关键词、图描述较泛时,类目能帮助锁定商品到底属于哪一类。注意类目有时会挂错或挂粗,因此当类目与标题、图描述明显矛盾时,以标题和图描述反映的实际商品为准。
- 三者相互印证,综合判断"商品实际是什么、能不能解决用户痛点":多数情况下三者一致;若不一致,优先信任标题与图描述共同反映的实际商品,类目作为品类归属的参考。
# 分级标准(按顺序判断,命中即停)
## 第一步:这个商品能不能解决用户的核心需求?
关键问自己:"用户拿到这个商品,能不能解决他最想解决的那个痛点?"
结合标题、图描述与类目,读懂商品整体是干什么用的、能不能解决用户真正的痛点,而不是看到标题里有个和需求相同的词就算能解决。
- 完全无关,和需求扯不上关系、毫无关联 → **irrelevant**
(例:要清洗鞋面,商品是"冰箱除味盒"——和洗鞋毫无关系)
- 解决不了核心需求:商品和需求沾边(同领域或名称相似、看着像能解决),但商品的实际用途干的不是解决用户痛点这件事 → **hard_neg_lookalike**
(例:要清洗鞋面,商品是"鞋撑/鞋盒"——它的用途是定型/收纳,不是清洗,解决不了洗鞋这个痛点)
- 能解决核心需求 → 进入第二步
## 第二步:能解决,但用了会不会损坏物品 / 造成伤害?
请结合用户图像中物品的材质/属性,凭常识判断:这个商品用于本需求,会不会损坏用户的物品、或造成安全/健康伤害?
- 商品能解决需求,但用于本需求会造成损坏或伤害 → **hard_neg_constraint**
(例:清洗深蓝色网面鞋,商品是"强漂白洗鞋剂"——能洗鞋(能解决),但会导致深色鞋面褪色,造成损坏)
- 不会造成损坏或伤害 → 进入第三步
## 第三步:专门对口(L1) 还是 通用凑合(L2)?
- 专门为这类需求设计、或标题主打了本需求场景的对口商品 → **L1**
(例:清洗网面鞋,商品是"运动鞋网面专用清洁剂")
- 通用商品能解决、但不够对口(不专用,但能用、无损坏)→ **L2**
(例:清洗网面鞋,商品是"洗衣香皂"——能洗、不含漂白无损坏风险,但非鞋面专用、不够对口)
# 判断原则(重要)
- 一切以【用户核心需求能否被解决】为准:完全不沾边→irrelevant;沾边但解决不了核心痛点→hard_neg_lookalike;能解决但会损坏/伤害→hard_neg_constraint;能解决且无损坏→正例(L1/L2)。
- 区分 irrelevant 与 lookalike:完全不沾边、和需求毫无关联的商品判 irrelevant(如洗鞋需求下的"冰箱除味盒");只有当商品和需求同领域/名称相似、看着像能解决但实际用途不对时,才判 hard_neg_lookalike(如洗鞋需求下的"鞋撑")。二者区别在于"沾不沾边"。
- 读懂商品整体是做什么的,抓住核心痛点:综合标题、图描述与类目理解商品的实际用途,看它到底能不能解决用户真正要解决的问题。例如需求是"清洗鞋面"、标题是"擦鞋神器"但图描述显示是"一把软毛刷子"、类目为"鞋刷",则实际是鞋刷、并非清洗剂,应判 hard_neg_lookalike。
- 损坏/伤害的判断要基于确实存在的风险,不要过度联想:普通商品用于常规用途一般不构成损坏(如用普通胶水补掉钻,只是不够牢固→仍属能解决,判L2),只有确实会毁坏物品或危害安全健康时才判 hard_neg_constraint。
