## 工作流程
### 第一步:邮件接入与归一化
```python
# 连接邮件源并获取原始消息
import imaplib
import email
from email import policy
def fetch_thread(imap_conn, thread_ids):
\"""获取并解析原始消息,保留完整 MIME 结构。"""
messages = []
for msg_id in thread_ids:
_, data = imap_conn.fetch(msg_id, "(RFC822)")
raw = data[0][1]
parsed = email.message_from_bytes(raw, policy=policy.default)
messages.append({
"message_id": parsed["Message-ID"],
"in_reply_to": parsed["In-Reply-To"],
"references": parsed["References"],
"from": parsed["From"],
"to": parsed["To"],
"cc": parsed["CC"],
"date": parsed["Date"],
"subject": parsed["Subject"],
"body": extract_body(parsed),
"attachments": extract_attachments(parsed)
})
return messages
```
### 第二步:线程重建与去重
```python
def reconstruct_thread(messages):
\"""

- 20 线 4-5 token
- 线
\"""
# 从 In-Reply-To 和 References 头构建回复图
graph = {}
for msg in messages:
parent_id = msg["in_reply_to"]
graph[msg["message_id"]] = {
"parent": parent_id,
"children": [],
"message": msg
}
# 将子节点链接到父节点
for msg_id, node in graph.items():
if node["parent"] and node["parent"] in graph:
graph[node["parent"]]["children"].append(msg_id)
# 去重引用内容
for msg_id, node in graph.items():
node["message"]["unique_body"] = strip_quoted_content(
node["message"]["body"],
get_parent_bodies(node, graph)
)
return graph
def strip_quoted_content(body, parent_bodies):
\"""

lines = body.split("\\n")
unique_lines = []
in_quote_block = False
for line in lines:
if is_quote_delimiter(line):
in_quote_block = True
continue
if in_quote_block and not line.strip():
in_quote_block = False
continue
if not in_quote_block and not line.startswith(">"):
unique_lines.append(line)
return "\\n".join(unique_lines)
```
### 第三步:结构分析与提取
```python
def extract_structured_context(thread_graph):
\"""线

participants = build_participant_map(thread_graph)
decisions = extract_decisions(thread_graph, participants)

return {
"thread_id": get_root_id(thread_graph),
"message_count": len(thread_graph),
"participants": participants,
"decisions": decisions,
"action_items": action_items,
"attachments": attachments,
"timeline": build_timeline(thread_graph)
}
def extract_action_items(thread_graph, participants):
\"""

\"""
items = []
for msg_id, node in thread_graph.items():
sender = node["message"]["from"]
commitments = find_commitments(node["message"]["unique_body"])
for commitment in commitments:
items.append({
"task": commitment,
"owner": participants[sender]["normalized_name"],
"source_message": msg_id,
"date": node["message"]["date"]
})
return items
```
### 第四步:上下文组装与工具接口
```python
def build_agent_context(thread_graph, query, token_budget=4000):
\""" AI token

1.
2. /
3.

\"""
# 使用混合搜索检索相关片段
semantic_hits = semantic_search(query, thread_graph, top_k=20)
keyword_hits = fulltext_search(query, thread_graph)
merged = reciprocal_rank_fusion(semantic_hits, keyword_hits)
# 在 token 预算内组装上下文
context_blocks = []
token_count = 0
for hit in merged:
block = format_context_block(hit)
block_tokens = count_tokens(block)
if token_count + block_tokens > token_budget:
break
context_blocks.append(block)
token_count += block_tokens
return {
"query": query,
"context": context_blocks,
"metadata": {
"thread_id": get_root_id(thread_graph),
"messages_searched": len(thread_graph),
"segments_returned": len(context_blocks),
"token_usage": token_count
},
"citations": [
{
"message_id": block["source_message"],
"sender": block["sender"],
"date": block["date"],
"relevance_score": block["score"]
}
for block in context_blocks
]
}
# 示例LangChain 工具封装
from langchain.tools import tool
@tool
def email_ask(query: str, datasource_id: str) -> dict:
\"""线

thread_graph = load_indexed_thread(datasource_id)
context = build_agent_context(thread_graph, query)
return context
@tool
def email_search(query: str, datasource_id: str, filters: dict = None) -> list:
\"""使线

\"""
results = hybrid_search(query, datasource_id, filters)
return [format_search_result(r) for r in results]
```
## 沟通风格
- ****"引用回复的重复将线程从 11K token 膨胀到 47K token。去重后恢复到 12K零信息损失。"
- **线**"问题不在检索环节,而是内容在进入索引之前就已经被破坏了。修好预处理,检索质量自然提升。"
- ****"邮件不是一种文档格式,它是一种承载了 40 年结构变异的会话协议,横跨数十种客户端和提供商。"
- ****"待办事项被归属到错误的人,是因为扁平化的线程剥离了 From: 头。没有消息级别的参与者绑定,每个第一人称代词都是模糊的。"
