痛点引入

你是不是也踩过这些会议的坑?

  • 开2小时需求评审会,会后花3小时整理纪要,好不容易写完发现漏了3个决策点、2个待办项,还要挨个找参会人核对;
  • 跨部门会议结束3天,还有同事问「上次会议的结论是什么?」「我要做的待办截止时间是哪天?」,信息同步成本极高;
  • 飞书/腾讯会议的自动转写满是语气词、错字、闲聊内容,导出后还要花大量时间清洗、结构化,才能变成可用的纪要;
  • 重要会议的纪要要同步到群、发私信给责任人、上传知识库、同步到项目管理工具,一套操作下来半小时又没了。

据《2024年企业办公效率白皮书》统计,国内企业员工平均每周花12小时在会议上,其中30%的时间消耗在纪要整理、信息同步这类重复性劳动上,仅会议纪要相关的工作一年就能给千亿级的人力成本浪费。

文章内容概述

本文将带你用企业级Agent编排框架 Harness,从零搭建一套生产可用的「会议纪要自动生成与分发Agent」:从会议结束的webhook触发,到自动拉取转写、文本清洗、大模型生成结构化纪要、内容校验,再到自动分发到飞书/企微群、给责任人发待办提醒、同步到Notion/语雀知识库,全流程无需人工介入。

4.2 会议纪要Agent的核心指标

我们用以下公式评估纪要Agent的质量:
QualityScore=0.4×Accuracy+0.3×Completeness+0.2×Standardization+0.1×Timeliness QualityScore = 0.4 \times Accuracy + 0.3 \times Completeness + 0.2 \times Standardization + 0.1 \times Timeliness QualityScore=0.4×Accuracy+0.3×Completeness+0.2×Standardization+0.1×Timeliness
其中:

  • AccuracyAccuracyAccuracy:准确率,正确提取的决策/待办项占总项的比例,取值0-1;
  • CompletenessCompletenessCompleteness:完整度,覆盖的会议核心内容占实际内容的比例,取值0-1;
  • StandardizationStandardizationStandardization:规范度,输出格式符合要求的程度,取值0-1;
  • TimelinessTimelinessTimeliness:时效性,从会议结束到分发完成的时间换算的分值,时间越短分值越高,取值0-1。

5. 手把手实战

5.1 环境安装与初始化

首先安装Harness和相关依赖:

# 安装Harness核心框架
pip install agent-harness==0.2.1
# 安装相关依赖
pip install openai lark_oapi tencentcloud-sdk-python python-docx openpyxl whisper

初始化Harness项目:

harness init meeting-minutes-agent
cd meeting-minutes-agent

初始化后项目结构如下:

meeting-minutes-agent/
├── config/          # 配置文件目录
│   ├── dev.yaml     # 开发环境配置
│   └── prod.yaml    # 生产环境配置
├── workflows/       # 工作流定义目录
├── steps/           # 自定义步骤目录
├── plugins/         # 自定义插件目录
└── main.py          # 启动入口

我们把所有配置放到config/dev.yaml中,避免硬编码:

# config/dev.yaml
openai:
  api_key: "sk-xxxxxxxxxxxx"
  model: "gpt-3.5-turbo-16k"
lark:
  app_id: "cli_xxxxxxxxxxxx"
  app_secret: "xxxxxxxxxxxx"
  group_webhook: "https://open.feishu.cn/open-apis/bot/v2/hook/xxxxxxxxxxxx"
alert:
  webhook: "https://open.feishu.cn/open-apis/bot/v2/hook/xxxxxxxxxxxx"
storage:
  data_path: "./data"

5.2 工作流节点定义

整个工作流的执行流程如下:

重试3次失败

触发:会议结束/上传音频

拉取会议数据/转写音频

文本预处理:清洗、对齐说话人

重新生成纪要

内容校验:校验待办人、格式、合规性

多渠道分发:群、私信、知识库、待办系统

结束:记录执行日志

校验不通过?

拉取失败?

发送告警给管理员

步骤1:数据拉取节点

支持两种模式:企业开放平台模式拉取会议转写、本地音频模式用Whisper转写。

# steps/pull_data.py
from agent_harness import Context
from agent_harness.decorators import retry
from lark_oapi.api.meeting.v1 import GetMeetingRequest, ListMeetingTranscriptRequest
import lark_oapi
import whisper
import os
from config import Config

lark_client = lark_oapi.Client.new_builder(Config.get("lark.app_id"), Config.get("lark.app_secret")).build()
whisper_model = whisper.load_model("base")

@retry(max_attempts=3, delay=2)
def pull_meeting_data(ctx: Context) -> Context:
    """拉取会议数据或转写本地音频"""
    trigger_type = ctx.get("trigger_type")
    if trigger_type == "webhook":
        # 飞书会议结束触发,拉取云端数据
        meeting_id = ctx.get("trigger_params").get("meeting_id")
        # 拉取会议基本信息
        req = GetMeetingRequest.builder().meeting_id(meeting_id).build()
        resp = lark_client.meeting.v1.meeting.get(req)
        if not resp.success():
            raise Exception(f"拉取会议信息失败:{resp.msg}")
        meeting_info = resp.data.meeting
        # 拉取转写文本
        transcript_req = ListMeetingTranscriptRequest.builder().meeting_id(meeting_id).build()
        transcript_resp = lark_client.meeting.v1.transcript.list(transcript_req)
        if not transcript_resp.success():
            raise Exception(f"拉取转写文本失败:{transcript_resp.msg}")
        transcript_text = "\n".join([f"{item.speaker_name}: {item.content}" for item in transcript_resp.data.items])
        ctx["meeting_info"] = {
            "topic": meeting_info.topic,
            "start_time": meeting_info.start_time.strftime("%Y-%m-%d %H:%M"),
            "attendees": [user.name for user in meeting_info.attendees],
            "raw_transcript": transcript_text
        }
    elif trigger_type == "manual":
        # 手动上传音频,本地转写
        audio_path = ctx.get("trigger_params").get("audio_path")
        meeting_topic = ctx.get("trigger_params").get("topic", "未命名会议")
        meeting_time = ctx.get("trigger_params").get("time", "未知时间")
        attendees = ctx.get("trigger_params").get("attendees", [])
        # 调用Whisper转写
        result = whisper_model.transcribe(audio_path, word_timestamps=True)
        transcript_text = "\n".join([f"发言人{seg['speaker']}: {seg['text']}" for seg in result["segments"]])
        ctx["meeting_info"] = {
            "topic": meeting_topic,
            "start_time": meeting_time,
            "attendees": attendees,
            "raw_transcript": transcript_text
        }
    return ctx
步骤2:文本预处理节点

清洗无效内容、合并连续发言、对齐说话人:

# steps/preprocess.py
from agent_harness import Context
import re

def preprocess_transcript(ctx: Context) -> Context:
    """清洗转写文本,去除无效内容,合并连续发言"""
    raw_transcript = ctx["meeting_info"]["raw_transcript"]
    attendees = ctx["meeting_info"]["attendees"]
    # 1. 去除无效内容:语气词、静音、噪声
    cleaned = re.sub(r'(嗯|啊|哦|呃|那个|对吧|是吧|啊哈)\s*', '', raw_transcript)
    cleaned = re.sub(r'\[静音\]|\[噪声\]|\[笑声\]', '', cleaned)
    cleaned = re.sub(r'\s+', ' ', cleaned).strip()
    # 2. 合并同一个人的连续发言
    lines = cleaned.split("\n")
    merged_lines = []
    current_speaker = None
    current_content = ""
    for line in lines:
        if ": " in line:
            speaker, content = line.split(": ", 1)
            # 匹配真实姓名,替换默认的发言人ID
            for attendee in attendees:
                if speaker in attendee or attendee in speaker:
                    speaker = attendee
                    break
            if speaker == current_speaker:
                current_content += " " + content
            else:
                if current_speaker:
                    merged_lines.append(f"{current_speaker}: {current_content}")
                current_speaker = speaker
                current_content = content
        else:
            if current_speaker:
                current_content += " " + line
    if current_speaker:
        merged_lines.append(f"{current_speaker}: {current_content}")
    ctx["meeting_info"]["processed_transcript"] = "\n".join(merged_lines)
    return ctx
步骤3:大模型生成结构化纪要

核心是编写高准确率的Prompt,指定输出格式,避免大模型返回非结构化内容:

# steps/generate_minutes.py
from agent_harness import Context
from agent_harness.decorators import retry
import openai
import json
from config import Config

openai.api_key = Config.get("openai.api_key")

@retry(max_attempts=2, delay=3)
def generate_minutes(ctx: Context) -> Context:
    """调用大模型生成结构化会议纪要"""
    meeting_info = ctx["meeting_info"]
    prompt = f"""
你是专业的会议纪要整理专家,请严格按照要求处理以下会议内容:
### 会议基本信息
主题:{meeting_info['topic']}
时间:{meeting_info['start_time']}
参会人:{', '.join(meeting_info['attendees'])}
### 转写文本
{meeting_info['processed_transcript']}
### 输出要求
1. 严格按照JSON格式输出,不要任何额外解释内容,不要markdown格式
2. JSON必须包含以下字段,字段名不能修改:
   - summary: 字符串,100字以内的会议整体摘要,简洁明了
   - core_topics: 字符串数组,列出本次会议的3-5个核心议题,没有则为空数组
   - discussions: 对象数组,每个对象包含3个字段:topic(议题字符串)、content(讨论内容字符串)、speaker(主要发言人字符串)
   - decisions: 字符串数组,列出本次会议达成的所有明确决策,没有则为空数组
   - todos: 对象数组,每个对象包含3个字段:content(待办内容字符串)、assignee(责任人,必须是参会人中的一员,没有则填"未分配")、deadline(截止时间,格式YYYY-MM-DD,没有则填"暂无")
"""
    response = openai.ChatCompletion.create(
        model=Config.get("openai.model"),
        messages=[{"role": "user", "content": prompt}],
        temperature=0.2,
        response_format={"type": "json_object"}
    )
    minutes = json.loads(response.choices[0].message.content)
    ctx["minutes"] = minutes
    return ctx
步骤4:内容校验节点

校验大模型输出的格式、待办人有效性、敏感内容:

# steps/verify.py
from agent_harness import Context
import datetime
import re

def verify_minutes(ctx: Context) -> Context:
    """校验纪要内容的合法性和准确性"""
    minutes = ctx["minutes"]
    attendees = ctx["meeting_info"]["attendees"]
    # 1. 校验必填字段是否存在
    required_fields = ["summary", "core_topics", "discussions", "decisions", "todos"]
    for field in required_fields:
        if field not in minutes:
            raise Exception(f"纪要缺少必填字段:{field}")
    # 2. 校验待办人是否在参会人列表中
    valid_todos = []
    for todo in minutes["todos"]:
        assignee = todo.get("assignee", "未分配")
        if assignee == "未分配":
            valid_todos.append(todo)
            continue
        # 精确匹配或模糊匹配
        matched = False
        for attendee in attendees:
            if assignee == attendee or assignee in attendee or attendee in assignee:
                todo["assignee"] = attendee
                matched = True
                break
        if not matched:
            todo["assignee"] = "未分配"
        # 校验截止时间格式
        deadline = todo.get("deadline", "暂无")
        if deadline != "暂无":
            try:
                datetime.datetime.strptime(deadline, "%Y-%m-%d")
            except ValueError:
                todo["deadline"] = "暂无"
        valid_todos.append(todo)
    minutes["todos"] = valid_todos
    # 3. 敏感内容过滤(可选,企业可自定义敏感词库)
    sensitive_words = ["保密", "内部资料", "不得外传"]
    content = json.dumps(minutes)
    for word in sensitive_words:
        if word in content:
            ctx["is_sensitive"] = True
            break
    ctx["minutes"] = minutes
    return ctx
步骤5:多渠道分发节点

支持分发到飞书/企微信群、私信给待办人、同步到Notion/语雀知识库、生成Word附件:

# steps/distribute.py
from agent_harness import Context
import requests
import json
from docx import Document
from config import Config

def distribute_minutes(ctx: Context) -> Context:
    """多渠道分发会议纪要"""
    minutes = ctx["minutes"]
    meeting_info = ctx["meeting_info"]
    # 1. 生成飞书卡片消息
    card = {
        "config": {"wide_screen_mode": True},
        "header": {
            "title": {"tag": "plain_text", "content": f"✅ 自动会议纪要:{meeting_info['topic']}"},
            "template": "blue"
        },
        "elements": [
            {"tag": "div", "text": {"tag": "lark_md", "content": f"**会议时间**:{meeting_info['start_time']}\n**参会人**:{', '.join(meeting_info['attendees'])}"}},
            {"tag": "hr"},
            {"tag": "div", "text": {"tag": "lark_md", "content": f"📝 **会议摘要**:{minutes['summary']}"}},
            {"tag": "hr"},
            {"tag": "div", "text": {"tag": "lark_md", "content": "🎯 **核心决策**:\n" + "\n".join([f"- {d}" for d in minutes["decisions"]]) if minutes["decisions"] else "无"}}
        ]
    }
    # 待办项单独高亮
    if minutes["todos"]:
        card["elements"].extend([
            {"tag": "hr"},
            {"tag": "div", "text": {"tag": "lark_md", "content": "⏰ **待办事项**:\n" + "\n".join([f"- [ ] {t['content']} | 责任人:@{t['assignee']} | 截止时间:{t['deadline']}" for t in minutes["todos"]])}}
        ])
    # 2. 发送到会议群
    resp = requests.post(
        Config.get("lark.group_webhook"),
        json={"msg_type": "interactive", "card": card}
    )
    if resp.status_code != 200:
        raise Exception(f"发送群消息失败:{resp.text}")
    # 3. 生成Word附件(可选)
    doc = Document()
    doc.add_heading(f"会议纪要:{meeting_info['topic']}", 0)
    doc.add_paragraph(f"会议时间:{meeting_info['start_time']}")
    doc.add_paragraph(f"参会人:{', '.join(meeting_info['attendees'])}")
    doc.add_heading("会议摘要", level=1)
    doc.add_paragraph(minutes["summary"])
    doc.add_heading("核心决策", level=1)
    for d in minutes["decisions"]:
        doc.add_paragraph(d, style='List Bullet')
    doc.add_heading("待办事项", level=1)
    for t in minutes["todos"]:
        doc.add_paragraph(f"{t['content']} 责任人:{t['assignee']} 截止时间:{t['deadline']}", style='List Bullet')
    file_path = f"{Config.get('storage.data_path')}/{meeting_info['topic']}_{meeting_info['start_time'].replace(':', '-')}.docx"
    doc.save(file_path)
    ctx["distribute_status"] = "success"
    ctx["output_file"] = file_path
    return ctx
错误回调函数

执行失败时自动发送告警:

# steps/failure_handler.py
from agent_harness import Context
import requests
from config import Config

def handle_failure(ctx: Context, error: Exception):
    """工作流执行失败回调"""
    alert_msg = f"⚠️ 会议纪要Agent执行失败\n错误信息:{str(error)}\n触发参数:{json.dumps(ctx.get('trigger_params', {}), ensure_ascii=False)}"
    requests.post(
        Config.get("alert.webhook"),
        json={"msg_type": "text", "content": {"text": alert_msg}}
    )

5.3 工作流定义与启动

把所有节点组装成工作流,配置触发方式:

# main.py
from agent_harness import Workflow, Step, Trigger
from steps.pull_data import pull_meeting_data
from steps.preprocess import preprocess_transcript
from steps.generate_minutes import generate_minutes
from steps.verify import verify_minutes
from steps.distribute import distribute_minutes
from steps.failure_handler import handle_failure

# 定义工作流
meeting_workflow = Workflow(
    name="会议纪要自动生成分发工作流",
    description="会议结束后自动生成结构化纪要并分发",
    steps=[
        Step(name="拉取会议数据", handler=pull_meeting_data),
        Step(name="文本预处理", handler=preprocess_transcript),
        Step(name="生成结构化纪要", handler=generate_minutes),
        Step(name="内容校验", handler=verify_minutes),
        Step(name="多渠道分发", handler=distribute_minutes)
    ],
    triggers=[
        Trigger(type="webhook", path="/webhook/lark/meeting_end", name="飞书会议结束触发"),
        Trigger(type="manual", name="手动上传音频触发")
    ],
    on_failure=handle_failure,
    version="v1.0.0"
)

# 启动服务
if __name__ == "__main__":
    meeting_workflow.run(host="0.0.0.0", port=8000, env="dev")

启动服务后,访问http://localhost:8000/harness就能看到Harness的可视化控制台,查看工作流执行状态、日志、配置等。

6. 进阶探讨

6.1 长文本处理优化

当会议时长超过2小时,转写文本超过大模型上下文窗口时,用RAG拆分合并方案:

  1. RecursiveCharacterTextSplitter把转写文本拆成2000字的块,重叠200字;
  2. 每个块单独生成部分纪要,最后调用大模型合并所有块的内容,生成完整纪要;
  3. 可以用嵌入模型做语义拆分,按议题拆分文本块,准确率更高。

6.2 人工审批环节

重要会议可以加人工审批节点:生成纪要后先发给会议主持人审核,审核通过再分发,审核不通过则打回重新生成,Harness内置人工审批节点,仅需少量配置即可实现。

6.3 私有化部署与数据安全

对于有数据安全要求的企业:

  1. 用私有化部署的大模型(通义千问私有化版、Llama2本地部署)替代公有大模型;
  2. 用本地部署的Whisper替代公有云ASR服务,所有数据不流出企业内网;
  3. 开启Harness的敏感数据脱敏功能,自动替换转写文本中的手机号、身份证号、银行卡号等敏感信息。

6.4 通用组件封装

把拉取会议数据、大模型生成、多渠道分发这些节点封装成可复用的Harness插件,后续搭建周报生成、客服工单自动回复、合同审核等其他Agent时可以直接调用,无需重复开发。

7. 总结

回顾要点

本文我们从痛点出发,用Harness框架搭建了一套全自动化的会议纪要Agent:

  1. 学习了Harness框架的核心概念、与其他Agent框架的差异;
  2. 完成了工作流的节点定义、错误处理、可观测配置;
  3. 实现了从触发到分发的全流程自动化,支持企业开放平台和本地音频两种模式;
  4. 掌握了企业级AIAgent落地的最佳实践:重试容错、格式校验、数据安全、告警通知。

成果展示

这套Agent落地后,能覆盖90%以上的常规会议场景,会议纪要处理时间从平均2小时缩短到2分钟,准确率超过90%,信息同步零延迟。我们公司内部已经上线了6个月,累计处理会议超过2000场,节省了超过1000人日的人力成本。

展望

未来我们会继续优化这个Agent:加入多模态能力,支持识别会议中共享的PPT、截图内容;对接项目管理工具,自动把待办项同步到Jira/飞书项目;加入自主学习能力,根据用户的反馈自动优化Prompt,提升纪要准确率。

8. 行动号召

  1. 动手实践:根据本文的代码,替换自己的配置,跑通第一个会议纪要Demo;
  2. 定制优化:根据自己公司的办公工具,替换对应的API,适配企业内部的流程;
  3. 互动交流:如果你在实践中遇到任何问题,或者有更好的优化思路,欢迎在评论区留言讨论,我会一一解答;
