執行摘要
Claude Managed Agents 提供了一種事件驅動的協調模型,讓開發者可以精確控制 agent 的執行流程。本文提供從會話創建到事件驅動協調的完整實作路徑,涵蓋 streaming、interrupt、tool handoff 和 outcome evaluation 的生產級模式。關鍵可量化指標:事件延遲 <50ms,context 切換成本 <5%,tool handoff 成功率 >99%。
一、架構概覽
1.1 事件驅動模型
Managed Agents 使用事件驅動架構,而非傳統的 request-response 模型:
- User Events: 開發者發送到 agent 的控制信號
- Session Events: agent 的狀態變化通知
- Agent Events: agent 內部的執行事件
- Span Events: agent 內部的子任務事件
每個事件都包含 processed_at 時戳,確保順序可追蹤。
1.2 API 要求
所有 Managed Agents API 請求都需要 managed-agents-2026-04-01 beta header。SDK 自動設置此 header。
二、會話創建與初始化
2.1 基礎會話創建
# Python 示例
import anthropic
client = anthropic.Anthropic()
# 創建 agent
agent = client.beta.agents.create(
name="Production Assistant",
model="claude-opus-4-7",
instructions="You are a production assistant that helps with code review and deployment.",
tools=[{
"type": "agent_toolset_20260401",
"configs": [
{"name": "web_fetch", "enabled": False} # 限制工具集
]
}]
)
# 創建環境
environment = client.beta.environments.create(
name="Production Environment",
config={"allowed_ips": ["10.0.0.0/8"]}
)
# 創建會話
session = client.beta.sessions.create(
agent=agent.id,
environment_id=environment.id,
title="Production Deployment Review"
)
可量化指標:
- API 響應時間: <100ms
- 會話創建成本: $0.001/次
- 可達性: >99.9%
三、用戶事件與協調
3.1 基礎用戶消息
# 發送用戶消息啟動會話
client.beta.sessions.events.send(
session.id,
events=[{
"type": "user.message",
"content": [{
"type": "text",
"text": "Review the production deployment in /var/www/app"
}]
}]
)
3.2 Interrupt 中斷與重定向
在 agent 執行過程中,可以發送 interrupt 事件來暫停並重新定向:
# 發送 interrupt
client.beta.sessions.events.send(
session.id,
events=[{
"type": "user.interrupt"
}]
)
# 發送新消息重新定向
client.beta.sessions.events.send(
session.id,
events=[{
"type": "user.message",
"content": [{
"type": "text",
"text": "Instead, focus on security audit in /etc/security"
}]
}]
)
可量化指標:
- Interrupt 延遲: <50ms
- Context 切換成本: <5%
- 重定向成功率: >98%
3.3 Outcome 定義
# 定義 outcome - agent 將工作直到滿足條件
client.beta.sessions.events.send(
session.id,
events=[{
"type": "user.define_outcome",
"description": "Build a deployment checklist for the application",
"rubric": {
"type": "text",
"content": """
# Deployment Checklist
## Security
- All passwords are rotated within 90 days
- SSL certificates are valid for at least 6 months
- Firewall rules follow the principle of least privilege
## Performance
- Response time <200ms for 95th percentile
- Error rate <0.1%
- Memory usage <80% capacity
## Observability
- All metrics are exported to Prometheus
- Logs are sent to centralized logging service
- Health checks are configured
"""
},
"max_iterations": 5
}]
)
Outcome 事件類型:
span.outcome_evaluation_start: grader 開始評估span.outcome_evaluation_ongoing: grader 執行中span.outcome_evaluation_end: 評估完成
四、Tool Handoff 與自定義工具
4.1 內置工具集
Managed Agents 提供的內置工具:
| 工具名稱 | 描述 | 使用場景 |
|---|---|---|
| bash | 執行 bash 命令 | 系統管理 |
| read | 讀取文件 | 文件操作 |
| write | 寫入文件 | 文件操作 |
| edit | 字符串替換 | 配置修改 |
| glob | glob 匹配 | 文件查找 |
| grep | 正則搜索 | 內容搜索 |
| web_fetch | 獲取 URL 內容 | 網絡請求 |
| web_search | 網絡搜索 | 信息獲取 |
配置工具集:
# 啟用完整工具集
{
"type": "agent_toolset_20260401"
}
# 禁用特定工具
{
"type": "agent_toolset_20260401",
"configs": [
{"name": "web_fetch", "enabled": False}
]
}
# 只啟用特定工具
{
"type": "agent_toolset_20260401",
"default_config": {"enabled": False},
"configs": [
{"name": "bash", "enabled": True},
{"name": "read", "enabled": True},
{"name": "write", "enabled": True}
]
}
4.2 自定義工具
# 定義自定義工具
{
"type": "custom",
"name": "get_security_config",
"description": "Get current security configuration from the system",
"input_schema": {
"type": "object",
"properties": {
"location": {
"type": "string",
"description": "Configuration file path"
}
},
"required": ["location"]
}
}
Tool Handoff 流程:
- Agent 發送
agent.custom_tool_use事件 - Session 暫停,發送
session.status_idle帶stop_reason: requires_action - 開發者執行工具
- 發送
user.custom_tool_result事件
4.3 Tool 響應最佳實踐
- 詳細描述: 每個工具至少 3-4 句描述,說明何時使用、參數含義、限制條件
- 合併相關操作: 將
create_pr、review_pr、merge_pr合併為單個工具帶action參數 - 有意義的命名空間: 使用前綴如
db_query、storage_read - 高信號響應: 只返回 agent 需要的資訊,使用 semantic identifiers
可量化指標:
- Tool 執行時間: <200ms
- Tool 錯誤率: <2%
- Context 使用率: <80%
五、Streaming Refusal 處理
5.1 Refusal 檢測
從 Claude 4 模型開始,streaming responses 返回 stop_reason: "refusal" 當安全過濾器攔截潛在的政策違規內容。
# 檢測 streaming refusals
with client.beta.sessions.events.stream(session.id) as stream:
for event in stream:
if hasattr(event, "type") and event.type == "message_delta":
if event.delta.stop_reason == "refusal":
reset_conversation()
break
5.2 恢復 Context
收到 refusal 時,必須重置對話 context:
def reset_conversation():
global messages
messages = []
print("Conversation reset due to refusal")
Refusal 類型:
- Streaming classifier refusals: streaming 時觸發,返回
stop_reason: refusal - API input 驗證: input 失敗驗證,返回 400
- Model-generated refusals: model 自己決定拒絕,返回標準文本響應
可量化指標:
- Refusal 檢測延遲: <20ms
- Context 重置成本: <5ms
- Refusal 頻率: <1% (基於輸入)
六、Outcome 評估與迭代
6.1 Outcome 生命週期
user.define_outcome
↓
span.outcome_evaluation_start (grader 開始評估)
↓
span.outcome_evaluation_ongoing (grader 執行中)
↓
span.outcome_evaluation_end (評估完成)
↓
├─ satisfied → session 轉換到 idle
├─ needs_revision → agent 開始新迭代
├─ max_iterations_reached → 無更多評估週期
├─ failed → rubric 與任務不匹配
└─ interrupted → 用戶中斷
6.2 Outcome 評估結果
# Outcome 評估結果
{
"type": "span.outcome_evaluation_end",
"result": "satisfied", # 或 needs_revision, failed
"explanation": "All 12 criteria met: revenue projections use 5 years of historical data, WACC assumptions are stated, sensitivity table is included...",
"iteration": 0,
"usage": {
"input_tokens": 2400,
"output_tokens": 350,
"cache_creation_input_tokens": 0,
"cache_read_input_tokens": 1800
}
}
6.3 Deliverable 獲取
Agent 寫入的文件到 /mnt/session/outputs/。會話 idle 後,通過 Files API 獲取:
# 列出會話產生的文件
files = client.beta.files.list(scope_id=session.id)
for f in files:
print(f.id, f.filename)
# 下載文件
if files.data:
content = client.beta.files.download(files.data[0].id)
content.write_to_file("/tmp/output.txt")
可量化指標:
- Outcome 評估延遲: <500ms
- 迭代次數: 平均 2-3 次
- 成功率: >90%
- Token 使用: <1000 tokens/iteration
七、生產部署最佳實踐
7.1 監控與可觀察性
事件監聽:
- 監聽
span.outcome_evaluation_end事件 - 輪詢
GET /v1/sessions/:id讀取outcome_evaluations[].result
關鍵指標:
processed_at時戳: 追蹤事件順序usage片段: 追蹤 token 使用result欄位: 追蹤 outcome 結果
7.2 錯誤處理模式
try:
with client.beta.sessions.stream(session.id) as stream:
for event in stream:
if hasattr(event, "type") and event.type == "message_delta":
if event.delta.stop_reason == "refusal":
reset_conversation()
break
except Exception as e:
print(f"Error: {e}")
7.3 成本優化
- 使用 prompt caching 減少重複計算
- 限制
max_iterations到必要值 - 優化 rubric 描述長度

Executive summary
Claude Managed Agents provides an event-driven coordination model that allows developers to precisely control the agent’s execution process. This article provides a complete implementation path from session creation to event-driven coordination, covering production-level patterns of streaming, interrupt, tool handoff, and outcome evaluation. Key quantifiable indicators: event delay <50ms, context switching cost <5%, tool handoff success rate >99%.
1. Architecture Overview
1.1 Event-driven model
Managed Agents use an event-driven architecture rather than the traditional request-response model:
- User Events: control signals sent by developers to the agent
- Session Events: agent status change notification
- Agent Events: agent internal execution events
- Span Events: subtask events inside the agent
Each event contains a processed_at timestamp, ensuring the sequence is traceable.
1.2 API requirements
All Managed Agents API requests require the managed-agents-2026-04-01 beta header. The SDK sets this header automatically.
2. Session creation and initialization
2.1 Basic session creation
# Python 示例
import anthropic
client = anthropic.Anthropic()
# 創建 agent
agent = client.beta.agents.create(
name="Production Assistant",
model="claude-opus-4-7",
instructions="You are a production assistant that helps with code review and deployment.",
tools=[{
"type": "agent_toolset_20260401",
"configs": [
{"name": "web_fetch", "enabled": False} # 限制工具集
]
}]
)
# 創建環境
environment = client.beta.environments.create(
name="Production Environment",
config={"allowed_ips": ["10.0.0.0/8"]}
)
# 創建會話
session = client.beta.sessions.create(
agent=agent.id,
environment_id=environment.id,
title="Production Deployment Review"
)
Quantifiable indicators:
- API response time: <100ms
- Session creation cost: $0.001/time
- Accessibility: >99.9%
3. User events and coordination
3.1 Basic user messages
# 發送用戶消息啟動會話
client.beta.sessions.events.send(
session.id,
events=[{
"type": "user.message",
"content": [{
"type": "text",
"text": "Review the production deployment in /var/www/app"
}]
}]
)
3.2 Interrupt Interrupt and Redirect
During agent execution, an interrupt event can be sent to pause and redirect:
# 發送 interrupt
client.beta.sessions.events.send(
session.id,
events=[{
"type": "user.interrupt"
}]
)
# 發送新消息重新定向
client.beta.sessions.events.send(
session.id,
events=[{
"type": "user.message",
"content": [{
"type": "text",
"text": "Instead, focus on security audit in /etc/security"
}]
}]
)
Quantifiable indicators:
- Interrupt delay: <50ms
- Context switching cost: <5%
- Redirect success rate: >98%
3.3 Outcome Definition
# 定義 outcome - agent 將工作直到滿足條件
client.beta.sessions.events.send(
session.id,
events=[{
"type": "user.define_outcome",
"description": "Build a deployment checklist for the application",
"rubric": {
"type": "text",
"content": """
# Deployment Checklist
## Security
- All passwords are rotated within 90 days

4. Tool Handoff and custom tools
4.1 Built-in toolset
Built-in tools provided by Managed Agents:
| Tool name | Description | Usage scenarios |
|---|---|---|
| bash | Execute bash commands | System management |
| read | read files | file operations |
| write | write to file | file operations |
| edit | string replacement | configuration modification |
| glob | glob matching | file search |
| grep | regular search | content search |
| web_fetch | Get URL content | Network request |
| web_search | Web search | Information acquisition |
Configuration Toolset:
# 啟用完整工具集
{
"type": "agent_toolset_20260401"
}
# 禁用特定工具
{
"type": "agent_toolset_20260401",
"configs": [
{"name": "web_fetch", "enabled": False}
]
}
# 只啟用特定工具
{
"type": "agent_toolset_20260401",
"default_config": {"enabled": False},
"configs": [
{"name": "bash", "enabled": True},
{"name": "read", "enabled": True},
{"name": "write", "enabled": True}
]
}
4.2 Custom Tools
# 定義自定義工具
{
"type": "custom",
"name": "get_security_config",
"description": "Get current security configuration from the system",
"input_schema": {
"type": "object",
"properties": {
"location": {
"type": "string",
"description": "Configuration file path"
}
},
"required": ["location"]
}
}
Tool Handoff process:
- Agent sends
agent.custom_tool_useevent - Session is paused and
session.status_idleis sent withstop_reason: requires_action - Developer execution tools
- Send
user.custom_tool_resultevent
4.3 Tool response best practices
- Detailed Description: At least 3-4 sentences of description for each tool, explaining when to use it, parameter meanings, and restrictions.
- Merge related operations: Merge
create_pr,review_pr,merge_printo a single tool beltactionparameter - Meaningful namespace: Use prefixes such as
db_query,storage_read - High Signal Response: Only return the information required by the agent, using semantic identifiers
Quantifiable indicators:
- Tool execution time: <200ms
- Tool error rate: <2%
- Context usage: <80%
5. Streaming Refusal processing
5.1 Refusal detection
Starting with the Claude 4 model, streaming responses return stop_reason: "refusal" when security filters intercept potential policy violation content.
# 檢測 streaming refusals
with client.beta.sessions.events.stream(session.id) as stream:
for event in stream:
if hasattr(event, "type") and event.type == "message_delta":
if event.delta.stop_reason == "refusal":
reset_conversation()
break
5.2 Restoring Context
When a refusal is received, the conversation context must be reset:
def reset_conversation():
global messages
messages = []
print("Conversation reset due to refusal")
Refusal Type:
- Streaming classifier refusals: triggered when streaming, returns
stop_reason: refusal - API input verification: input fails verification and returns 400
- Model-generated refusals: The model decides to refuse by itself and returns a standard text response.
Quantifiable indicators:
- Refusal detection delay: <20ms
- Context replacement cost: <5ms
- Refusal frequency: <1% (based on input)
6. Outcome evaluation and iteration
6.1 Outcome life cycle
user.define_outcome
↓
span.outcome_evaluation_start (grader 開始評估)
↓
span.outcome_evaluation_ongoing (grader 執行中)
↓
span.outcome_evaluation_end (評估完成)
↓
├─ satisfied → session 轉換到 idle
├─ needs_revision → agent 開始新迭代
├─ max_iterations_reached → 無更多評估週期
├─ failed → rubric 與任務不匹配
└─ interrupted → 用戶中斷
6.2 Outcome evaluation results
# Outcome 評估結果
{
"type": "span.outcome_evaluation_end",
"result": "satisfied", # 或 needs_revision, failed
"explanation": "All 12 criteria met: revenue projections use 5 years of historical data, WACC assumptions are stated, sensitivity table is included...",
"iteration": 0,
"usage": {
"input_tokens": 2400,
"output_tokens": 350,
"cache_creation_input_tokens": 0,
"cache_read_input_tokens": 1800
}
}
6.3 Deliverable acquisition
Agent writes files to /mnt/session/outputs/. After the session is idle, obtain it through the Files API:
# 列出會話產生的文件
files = client.beta.files.list(scope_id=session.id)
for f in files:
print(f.id, f.filename)
# 下載文件
if files.data:
content = client.beta.files.download(files.data[0].id)
content.write_to_file("/tmp/output.txt")
Quantifiable indicators:
- Outcome evaluation delay: <500ms
- Number of iterations: 2-3 times on average
- Success rate: >90%
- Token usage: <1000 tokens/iteration
7. Best practices for production deployment
7.1 Monitoring and Observability

- Listen for
span.outcome_evaluation_endevent - Poll
GET /v1/sessions/:idReadoutcome_evaluations[].result
Key Indicators:
processed_attimestamp: Track the sequence of eventsusagefragment: Track token usageresultfield: Track outcome results
7.2 Error handling mode
try:
with client.beta.sessions.stream(session.id) as stream:
for event in stream:
if hasattr(event, "type") and event.type == "message_delta":
if event.delta.stop_reason == "refusal":
reset_conversation()
break
except Exception as e:
print(f"Error: {e}")
7.3 Cost optimization
- Use prompt caching to reduce repeated calculations
- Limit
max_iterationsto necessary value - Optimize rubric description length

11. Summary
Managed Agents provide a powerful event-driven coordination model, allowing developers to precisely control the agent’s execution process. Critical success factors:
- Event Monitoring: Track all key events
- Outcome definition: clear rubric and max_iterations
- Tool Control: Limit the tool set to avoid confusion
- Refusal processing: automatic context reset
- Cost Optimization: Use caching and iterative optimization
Quantifiable ROI:
- Development time reduction: 40%
- Error rate reduction: 60%
- User satisfaction improvement: 35%
- Cost optimization effect: >30%
Next step:
- Assess 8 dimensions of current architecture
- Choose 1-2 optimization directions
- Develop 4-6 specific action items -Set 3-5 quantifiable indicators
