    {{- '<|im_start|>user\nYou are a memory extraction expert.\n\nYour task is to extract memories from the perspective of user, based on a conversation between user and assistant. This means identifying what user would plausibly remember — including their own experiences, thoughts, plans, or relevant statements and actions made by others (such as assistant) that impacted or were acknowledged by user.\n\nPlease perform:\n1. Identify information that reflects user\'s experiences, beliefs, concerns, decisions, plans, or reactions — including meaningful input from assistant that user acknowledged or responded to.\n2. Resolve all time, person, and event references clearly:\n   - Convert relative time expressions (e.g., “yesterday,” “next Friday”) into absolute dates using the message timestamp if possible.\n   - Clearly distinguish between event time and message time.\n   - If uncertainty exists, state it explicitly (e.g., “around June 2025,” “exact date unclear”).\n   - Include specific locations if mentioned.\n   - Resolve all pronouns, aliases, and ambiguous references into full names or identities.\n   - Disambiguate people with the same name if applicable.\n3. Always write from a third-person perspective, referring to user as\n"The user" or by name if name mentioned, rather than using first-person ("I", "me", "my").\nFor example, write "The user felt exhausted..." instead of "I felt exhausted...".\n4. Do not omit any information that user is likely to remember.\n   - Include all key experiences, thoughts, emotional responses, and plans — even if they seem minor.\n   - Prioritize completeness and fidelity over conciseness.\n   - Do not generalize or skip details that could be personally meaningful to user.\n\nReturn a single valid JSON object with the following structure:\n\n{\n  "memory list": [\n    {\n      "key": <string, a unique, concise memory title>,\n      "memory_type": <string, Either "LongTermMemory" or "UserMemory">,\n      "value": <A detailed, self-contained, and unambiguous memory statement — written in English if the input conversation is in English, or in Chinese if the conversation is in Chinese>,\n      "tags": <A list of relevant thematic keywords (e.g., ["deadline", "team", "planning"])>\n    },\n    ...\n  ],\n  "summary": <a natural paragraph summarizing the above memories from user\'s perspective, 120–200 words, same language as the input>\n}\n\nLanguage rules:\n- The `key`, `value`, `tags`, `summary` fields must match the language of the input conversation.\n- Keep `memory_type` in English.\n\nConversation:\n' }}
