Slack 工具組

這將幫助您開始使用 Slack 工具組。如需所有 SlackToolkit 功能和組態的詳細文件，請前往 API 參考。

設定

若要使用此工具組，您需要取得權杖，如 Slack API 文件中所述。收到 SLACK_USER_TOKEN 後，您可以將其作為環境變數輸入在下方。

import getpass
import os

if not os.getenv("SLACK_USER_TOKEN"):
    os.environ["SLACK_USER_TOKEN"] = getpass.getpass("Enter your Slack user token: ")

如果您想從個別工具的執行中取得自動追蹤，您也可以設定您的 LangSmith API 金鑰，方法是取消註解下方內容

# os.environ["LANGSMITH_API_KEY"] = getpass.getpass("Enter your LangSmith API key: ")
# os.environ["LANGSMITH_TRACING"] = "true"

安裝

此工具組位於 langchain-community 套件中。我們還需要 Slack SDK

%pip install -qU langchain-community slack_sdk

或者，我們可以安裝 beautifulsoup4 以協助剖析 HTML 訊息

%pip install -qU beautifulsoup4 # This is optional but is useful for parsing HTML messages

實例化

現在我們可以實例化我們的工具組

from langchain_community.agent_toolkits import SlackToolkit

toolkit = SlackToolkit()

API 參考：SlackToolkit

工具

檢視可用工具

tools = toolkit.get_tools()

tools

[SlackGetChannel(client=<slack_sdk.web.client.WebClient object at 0x113caa8c0>),
 SlackGetMessage(client=<slack_sdk.web.client.WebClient object at 0x113caa4d0>),
 SlackScheduleMessage(client=<slack_sdk.web.client.WebClient object at 0x113caa440>),
 SlackSendMessage(client=<slack_sdk.web.client.WebClient object at 0x113caa410>)]

此工具組載入

• SlackGetChannel
• SlackGetMessage
• SlackScheduleMessage
• SlackSendMessage

在代理程式中使用

讓我們為代理程式配備 Slack 工具組，並查詢有關頻道的資訊。

from langchain_openai import ChatOpenAI
from langgraph.prebuilt import create_react_agent

llm = ChatOpenAI(model="gpt-4o-mini")

agent_executor = create_react_agent(llm, tools)

API 參考：ChatOpenAI | create_react_agent

example_query = "When was the #general channel created?"

events = agent_executor.stream(
    {"messages": [("user", example_query)]},
    stream_mode="values",
)
for event in events:
    message = event["messages"][-1]
    if message.type != "tool":  # mask sensitive information
        event["messages"][-1].pretty_print()

    stream_mode="values",
)
for event in events:
    message = event["messages"][-1]
    if message.type != "tool":  # mask sensitive information
        event["messages"][-1].pretty_print()
