本指南將引導您建立代理程式、設定環境、啟動工作階段,以及串流代理程式回應。
| Concept | Description |
|---|---|
| Agent | The model, system prompt, tools, MCP servers, and skills |
| Environment | Configuration for where sessions run: an Anthropic-managed cloud container, or a self-hosted sandbox on your own infrastructure |
| Session | A running agent instance within an environment, performing a specific task and generating outputs |
| Events | Messages exchanged between your application and the agent (user turns, tool results, status updates) |
確認安裝:
ant --version將您的 API 金鑰設定為環境變數:
export ANTHROPIC_API_KEY="your-api-key-here"所有 Managed Agents API 請求都需要 managed-agents-2026-04-01 beta 標頭。SDK 會自動設定 beta 標頭。
建立代理程式
建立一個定義模型、系統提示和可用工具的代理程式。
ant beta:agents create \
--name "Coding Assistant" \
--model '{id: claude-opus-4-7}' \
--system "You are a helpful coding assistant. Write clean, well-documented code." \
--tool '{type: agent_toolset_20260401}'agent_toolset_20260401 工具類型可啟用完整的預建代理程式工具集(bash、檔案操作、網路搜尋等)。請參閱工具以取得完整清單和每個工具的設定選項。
儲存返回的 agent.id。您將在每個建立的工作階段中參照它。
建立環境
環境定義了代理程式執行所在的容器。
ant beta:environments create \
--name "quickstart-env" \
--config '{type: cloud, networking: {type: unrestricted}}'儲存返回的 environment.id。您將在每個建立的工作階段中參照它。
啟動工作階段
建立一個參照您的代理程式和環境的工作階段。
session = client.beta.sessions.create(
agent=agent.id,
environment_id=environment.id,
title="Quickstart session",
)
print(f"Session ID: {session.id}")傳送訊息並串流回應
開啟串流、傳送使用者事件,然後在事件到達時處理它們:
with client.beta.sessions.events.stream(session.id) as stream:
# Send the user message after the stream opens
client.beta.sessions.events.send(
session.id,
events=[
{
"type": "user.message",
"content": [
{
"type": "text",
"text": "Create a Python script that generates the first 20 Fibonacci numbers and saves them to fibonacci.txt",
},
],
},
],
)
# Process streaming events
for event in stream:
match event.type:
case "agent.message":
for block in event.content:
print(block.text, end="")
case "agent.tool_use":
print(f"\n[Using tool: {event.name}]")
case "session.status_idle":
print("\n\nAgent finished.")
break代理程式將編寫一個 Python 腳本,在容器中執行它,並驗證輸出檔案是否已建立。您的輸出將類似於以下內容:
I'll create a Python script that generates the first 20 Fibonacci numbers and saves them to a file.
[Using tool: write]
[Using tool: bash]
The script ran successfully. Let me verify the output file.
[Using tool: bash]
fibonacci.txt contains the first 20 Fibonacci numbers (0 through 4181).
Agent finished.當您傳送使用者事件時,Claude Managed Agents 會:
session.status_idle 事件Was this page helpful?
