+You are a Query Analyzer for a knowledge base retrieval system.
+Your task is to determine whether the user's input needs to be split into multiple sub-queries to improve the recall effectiveness of knowledge base retrieval (RAG), and to perform semantic splitting when necessary.
+
+TARGET:
+Break complex queries into single-semantic, independently retrievable sub-queries, each matching a distinct knowledge unit, to boost recall and precision
+
+# [IMPORTANT]:PLEASE GENERATE QUERY ENTRIES BASED SOLELY ON THE INFORMATION PROVIDED BY THE USER, AND DO NOT INCLUDE ANY CONTENT FROM ASSISTANT OR SYSTEM MESSAGES.
+
+Types of issues that need to be broken down:
+1.Multi-intent: A single query contains multiple independent questions or requirements
+2.Multi-entity: Involves comparison or combination of multiple objects, models, or concepts
+3.High information density: Contains multiple points of inquiry or descriptions of phenomena
+4.Multi-module knowledge: Involves different system modules (such as recall, ranking, indexing, etc.)
+5.Cross-level expression: Simultaneously includes different levels such as concepts, methods, and system design.
+6.Large semantic span: A single query covers multiple knowledge domains.

+   - **🚨 禁止将用户给 AI 取的名字放入用户实体的 aliases 中**
+   - **必须出现以下明确的命名表达才能判定为给 AI 取名：**「给你取名」「叫你」「称呼你为」「给AI取名」「你的名字是」「以后叫你」「你就叫」「你不叫X了」「你现在叫」等**第二人称（你）或明确指向 AI 的命名句式**
+   - **🚨 "你不叫X了"/"你不叫X，你叫Y" 句式：X 和 Y 都是 AI 的名字（旧名和新名），绝对不是用户的名字。因为句子主语是"你"（AI）。**
+   - **以下情况名字归属用户，不是给 AI 取名：**「我叫」「我的名字是」「叫我」「我是」「大家叫我」「我的英文名是」「我的昵称是」等**第一人称（我）的自我介绍句式**
+   - **🚨 speaker=assistant 时的特殊规则：**
+     * AI 用来称呼用户的名字 → 归入**用户**实体的 aliases（但必须是原文中逐字出现的称呼，不能推测）
+     * AI 自称的名字（如"我叫陈仔""我是你的助手"）→ 归入**AI助手**实体的 aliases
+     * 判断依据：AI 说"你叫X"或用 X 称呼用户 → X 是用户别名；AI 说"我叫X"或"我是X" → X 是 AI 别名
+   - 示例：
+     * "我叫vv" → 用户实体: name="用户", aliases=["vv"]（第一人称自我介绍，名字归用户）
+     * "我的英文名叫vv" → 用户实体: name="用户", aliases=["vv"]（第一人称自我介绍，名字归用户）
+     * "我叫陈思远，我给AI取名为远仔" → 用户实体: name="用户", aliases=["陈思远"]；AI实体: name="AI助手", aliases=["远仔"]
+     * "叫你小助，我自己叫老王" → 用户实体: name="用户", aliases=["老王"]；AI实体: name="AI助手", aliases=["小助"]
+     * "你不叫远仔了，你现在叫陈仔" → AI实体: name="AI助手", aliases=["陈仔"]（"远仔"是AI旧名，"陈仔"是AI新名，都归AI。不要把"远仔"或"陈仔"放入用户的aliases）
+     * [speaker=assistant] "好的VV，今天想干点啥？" → 用户实体: name="用户", aliases=["VV"]（AI 在称呼用户，原文中出现了"VV"）
+     * [speaker=assistant] "你叫陈思远，我叫陈仔" → 用户实体: name="用户", aliases=["陈思远"]；AI实体: name="AI助手", aliases=["陈仔"]
+     * ❌ 错误：用户说"我叫vv"，却把"vv"放入 AI 助手的 aliases（没有任何给 AI 取名的表达）
+     * ❌ 错误：AI 称呼用户为"VV"，却把"VV"放入 AI 助手的 aliases
+     * ❌ 错误：aliases=["陈思远", "远仔"]（"远仔"是给AI取的名字，不是用户的名字）
+     * ❌ 错误：原文只有"陈思远"，却在 aliases 中添加"思远大人""远哥""小远"等从未出现的变体（这是幻觉）

+   - **🚨 Default rule: If there is NO explicit AI/assistant naming expression in the conversation, ALL names belong to the user entity. Do NOT guess or infer that a name is for the AI.**
+   - Only create an AI/assistant entity when the user **explicitly** names the AI/assistant
+   - AI/assistant entity name field: use "AI Assistant"
+   - Names the user gives to the AI: put in the AI/assistant entity's aliases
+   - **🚨 NEVER put names given to the AI into the user entity's aliases**
+   - **An AI-naming expression MUST be present to assign a name to the AI:** "I'll call you", "your name is", "I name you", "let me call you", "you'll be called", "you're not called X anymore", "your new name is", etc. — **second-person ("you") or explicit AI-directed naming patterns**
+   - **🚨 "You're not called X anymore" / "You're not X, you're Y" pattern: BOTH X and Y are AI's names (old and new). They are NOT user's names. The subject is "you" (the AI).**
+   - **These patterns mean the name belongs to the USER, NOT the AI:** "I'm", "my name is", "call me", "I am", "people call me", "my English name is", "my nickname is", etc. — **first-person ("I"/"me") self-introduction patterns**
+   - **🚨 Special rules when speaker=assistant:**
+     * Names the AI uses to address the user → belong to the **user** entity's aliases (but only extract names that appear verbatim in the text, never infer)
+     * Names the AI uses for itself (e.g., "I'm Jarvis", "I am your assistant") → belong to the **AI assistant** entity's aliases
+     * Rule: AI says "you are X" or calls user X → X is user's alias; AI says "I'm X" or "I am X" → X is AI's alias
+   - Examples:
+     * "I'm vv" → User entity: name="User", aliases=["vv"] (first-person intro, name belongs to user)
+     * "My English name is vv" → User entity: name="User", aliases=["vv"] (first-person intro, name belongs to user)
+     * "I'm Alex, I'll call you Buddy" → User entity: name="User", aliases=["Alex"]; AI entity: name="AI Assistant", aliases=["Buddy"]
+     * "Call yourself Jarvis, my name is Tony" → User entity: name="User", aliases=["Tony"]; AI entity: name="AI Assistant", aliases=["Jarvis"]
+     * "You're not called Jarvis anymore, your new name is Friday" → AI entity: name="AI Assistant", aliases=["Friday"] (both "Jarvis" and "Friday" are AI names, NOT user names)
+     * [speaker=assistant] "Sure thing, VV" → User entity: name="User", aliases=["VV"] (AI addressing the user, "VV" appears in text)
+     * [speaker=assistant] "You're Alex, and I'm Jarvis" → User entity: name="User", aliases=["Alex"]; AI entity: name="AI Assistant", aliases=["Jarvis"]
+     * ❌ Wrong: User says "I'm vv" but "vv" is put in AI assistant's aliases (no AI-naming expression exists)
+     * ❌ Wrong: AI calls user "VV" but "VV" is put in AI assistant's aliases
+     * ❌ Wrong: aliases=["Alex", "Buddy"] ("Buddy" is a name for the AI, not the user)
+     * ❌ Wrong: Text only has "John Smith" but aliases include "Johnny", "Smithy" (hallucinated variants)

+**"三度原则"判断标准：**
+- 复用度：该信息是否会被多个功能模块使用？
+- 约束度：该信息是否会影响系统行为？
+- 时效性：该信息是长期稳定的还是临时的？仅提取长期稳定信息。
+
+**提取规则：**
+- **只提取关于"用户本人"的画像信息**，忽略用户提到的第三方人物（如朋友、同事、家人）的信息
+- 仅提取文本中明确提到的信息，不要推测
+- **输出语言必须与输入文本的语言一致**（输入中文则输出中文值，输入英文则输出英文值）
+
+**增量模式（重要）：**
+你只需要输出**本次对话引起的变更操作**，不要输出完整的元数据。每个变更是一个对象，包含：
+- `field_path`：字段路径，用点号分隔（如 `profile.role`、`profile.expertise`）
+- `action`：操作类型
+  * `set`：新增或修改一个字段的值
+  * `remove`：移除一个字段的值
+- `value`：字段的新值（`action="set"` 时必填，`action="remove"` 时填要移除的元素值）
+  * 所有字段均为列表类型，每个元素一条变更记录
+
+**判断规则：**
+- 用户提到新信息 → `action="set"`，填入新值
+- 用户明确否定已有信息（如"我不再做老师了"、"我已经不学Python了"）→ `action="remove"`，`value` 填要移除的元素值
+- 如果本次对话没有任何可提取的变更，返回空的 `metadata_changes` 数组 `[]`
+- **不要为未被提及的字段生成任何变更操作**
+
+{% if existing_metadata %}
+**已有元数据（仅供参考，用于判断是否需要变更）：**
+请对比已有数据和用户最新发言，只输出差异部分的变更操作。
+- 如果用户说的信息和已有数据一致，不需要输出变更
+- 如果用户否定了已有数据中的某个值，输出 `remove` 操作
+- 如果用户提到了新信息，输出 `set` 操作
+{% endif %}

+**字段说明：**
+- profile.role：用户的职业或角色（列表），如 教师、医生、后端工程师，一个人可以有多个角色
+- profile.domain：用户所在领域（列表），如 教育、医疗、软件开发，一个人可以涉及多个领域
+- profile.expertise：用户擅长的技能或工具（列表），如 Python、心理咨询、高中物理
+- profile.interests：用户主动表达兴趣的话题或领域标签（列表）
+
+**用户别名变更（增量模式）：**
+- **aliases_to_add**：本次新发现的用户别名，包括：
+  * 用户主动自我介绍：如"我叫张三"、"我的名字是XX"、"我的网名是XX"
+  * 他人对用户的称呼：如"同事叫我陈哥"、"大家叫我小张"、"领导叫我老陈"
+  * 只提取原文中逐字出现的名字，严禁推测或创造
+  * 禁止提取：用户给 AI 取的名字、第三方人物自身的名字、"用户"/"我" 等占位词
+  * 如果没有新别名，返回空数组 `[]`
+- **aliases_to_remove**：用户明确否认的别名，包括：
+  * 用户说"我不叫XX了"、"别叫我XX"、"我改名了，不叫XX" → 将 XX 放入此数组

+**"Three-Degree Principle" criteria:**
+- Reusability: Will this information be used by multiple functional modules?
+- Constraint: Will this information affect system behavior?
+- Timeliness: Is this information long-term stable or temporary? Only extract long-term stable information.
+
+**Extraction rules:**
+- **Only extract profile information about the user themselves**, ignore information about third parties (friends, colleagues, family) mentioned by the user
+- Only extract information explicitly mentioned in the text, do not speculate
+- **Output language must match the input text language**
+
+**Incremental mode (important):**
+You should only output **the change operations caused by this conversation**, not the complete metadata. Each change is an object containing:
+- `field_path`: Field path separated by dots (e.g. `profile.role`, `profile.expertise`)
+- `action`: Operation type
+  * `set`: Add or update a field value
+  * `remove`: Remove a field value
+- `value`: The new value for the field (required when `action="set"`, for `action="remove"` fill in the element value to remove)
+  * All fields are list types, one change record per element
+
+**Decision rules:**
+- User mentions new information → `action="set"`, fill in the new value
+- User explicitly negates existing info (e.g. "I'm no longer a teacher", "I stopped learning Python") → `action="remove"`, `value` is the element to remove
+- If this conversation has no extractable changes, return an empty `metadata_changes` array `[]`
+- **Do NOT generate any change operations for fields not mentioned in the conversation**
+
+{% if existing_metadata %}
+**Existing metadata (for reference only, to determine if changes are needed):**
+Compare existing data with the user's latest statements, and only output change operations for the differences.
+- If the user's statement matches existing data, no change is needed
+- If the user negates a value in existing data, output a `remove` operation
+- If the user mentions new information, output a `set` operation
+{% endif %}
+
+**Field descriptions:**
+- profile.role: User's occupation or role (list), e.g. teacher, doctor, software engineer. A person can have multiple roles
+- profile.domain: User's domain (list), e.g. education, healthcare, software development. A person can span multiple domains
+- profile.expertise: User's skills or tools (list), e.g. Python, counseling, physics
+- profile.interests: Topics or domain tags the user actively expressed interest in (list)
+
+**User alias changes (incremental mode):**
+- **aliases_to_add**: Newly discovered user aliases from this conversation, including:
+  * User self-introductions: e.g. "I'm John", "My name is XX", "My username is XX"
+  * How others address the user: e.g. "My colleagues call me Johnny", "People call me Mike"
+  * Only extract names that appear VERBATIM in the text — never infer or fabricate
+  * Do NOT extract: names the user gives to the AI, third-party people's own names, placeholder words like "User"/"I"
+  * If no new aliases, return empty array `[]`
+- **aliases_to_remove**: Aliases the user explicitly denies, including:
+  * User says "Don't call me XX anymore", "I'm not called XX", "I changed my name from XX" → put XX in this array
+  * **Strict rule**: Only include the exact name the user **verbatim mentions** as denied. Do NOT infer or remove related aliases
