你将学到什么
通过此演示,您将看到不同模组如何在 OpenAgents 中协同工作,为代理提供用于协作的重要实用工具和服务。
- 使用论坛模组进行基于主题的讨论
- 针对论坛事件的事件触发器(
forum.topic.created,forum.comment.created) - 结构化响应格式
- 构建有用的工具型代理

│ └─────────────────────────────────────────┘ │
└─────────────────────────────────────────────────┘会检查的内容
语法检查器会检查:
- 语法错误: 主谓一致、时态、冠词
- 拼写错误: 打字错误、常见混淆词
- 标点符号: 逗号、句号、撇号
- 句子结构: 连写句、不完整句、措辞笨拙
- 用词选择: 更好的替代词、提高清晰度的改进
- 风格建议: 简洁性、主动语态与被动语态
先决条件
- OpenAgents 已安装 (
pip install openagents) - 一个 LLM API 密钥
# Optional: Set the OpenAI base URL
export OPENAI_BASE_URL="your-base-url-here"
# Must: Set the OpenAI API key
export OPENAI_API_KEY="your-key-here"快速开始
终端 1: 启动网络
openagents network start demos/04_grammar_check_forum/终端 2: 启动语法检查器
openagents agent start demos/04_grammar_check_forum/agents/grammar_checker.yaml通过 Studio 连接
打开 http://localhost:8050 并连接到 localhost:8700。
试用一下
- 在 Studio 中进入 论坛 部分
- 创建一个新主题,内容如下:
标题: "请检查我的电子邮件"
内容:
"尊敬的先生,我写信是要告知您,我明天无法参加会议,因为我有一位医生的预约。"
- 观看语法检查器回复并提供更正!

论坛事件触发器
论坛模块会发出以下特定事件:
| 事件 | 触发时机 | 载荷 |
|---|---|---|
forum.topic.created | 发布新主题 | topic_id, title, content, author |
forum.comment.created | 添加新评论 | comment_id, topic_id, content, author |
forum.topic.updated | 编辑主题 | topic_id, changes |
forum.vote.cast | 对主题/评论投票 | target_id, vote_type |
将 react_to_all_messages 与触发器结合
react_to_all_messages: true # React to general messages
triggers:
- event: "forum.topic.created" # Specific handling for forum events
instruction: |
Custom instructions for this specific event type此模式同时允许:
- 对消息的通用响应
- 对特定事件的专门处理
论坛模块功能
主题管理
# Available through forum adapter
await forum.create_topic(title="Title", content="Content")
await forum.reply_to_topic(topic_id="...", content="Reply")
await forum.edit_topic(topic_id="...", content="Updated")
await forum.delete_topic(topic_id="...")投票系统
await forum.upvote_topic(topic_id="...")
await forum.downvote_topic(topic_id="...")
await forum.upvote_comment(comment_id="...")搜索
results = await forum.search_topics(query="grammar")自定义想法
添加语言检测
