# s10: Team Protocols (团队协议)

`s01 > s02 > s03 > s04 > s05 > s06 | s07 > s08 > s09 > [ s10 ] s11 > s12`

## 问题
|
|
|
|
s09 中队友能干活能通信, 但缺少结构化协调:
|
|
|
|
**关机**: 直接杀线程会留下写了一半的文件和过期的 config.json。需要握手 -- 领导请求, 队友批准 (收尾退出) 或拒绝 (继续干)。
|
|
|
|
**计划审批**: 领导说 "重构认证模块", 队友立刻开干。高风险变更应该先过审。
|
|
|
|
两者结构一样: 一方发带唯一 ID 的请求, 另一方引用同一 ID 响应。
|
|
|
|
## 解决方案

Shutdown Protocol Plan Approval Protocol
|
|
================== ======================
|
|
|
|
Lead Teammate Teammate Lead
|
|
| | | |
|
|
|--shutdown_req-->| |--plan_req------>|
|
|
| {req_id:"abc"} | | {req_id:"xyz"} |
|
|
| | | |
|
|
|<--shutdown_resp-| |<--plan_resp-----|
|
|
| {req_id:"abc", | | {req_id:"xyz", |
|
|
| approve:true} | | approve:true} |
|
|
|
|
Shared FSM:
|
|
[pending] --approve--> [approved]
|
|
[pending] --reject---> [rejected]
|
|
|
|
Trackers:
|
|
shutdown_requests = {req_id: {target, status}}
|
|
plan_requests = {req_id: {from, plan, status}}
|
|
```
|
|
|
|
## 工作原理
|
|
|
|
1. 领导生成 request_id, 通过收件箱发起关机请求。
|
|
|
|
```java
|
|
// src/main/java/io/mybatis/learn/s10/ProtocolTracker.java
|
|
// Python用字典 + threading.Lock; Java用ConcurrentHashMap天然线程安全
|
|
private final ConcurrentHashMap<String, Map<String, String>> shutdownRequests
|
|
= new ConcurrentHashMap<>();
|
|
|
|
public String handleShutdownRequest(String teammate) {
|
|
String reqId = UUID.randomUUID().toString().substring(0, 8);
|
|
shutdownRequests.put(reqId, new ConcurrentHashMap<>(Map.of(
|
|
"target", teammate, "status", "pending")));
|
|
bus.send("lead", teammate, "Please shut down gracefully.",
|
|
"shutdown_request", Map.of("request_id", reqId));
|
|
return "Shutdown request " + reqId + " sent to '" + teammate
|
|
+ "' (status: pending)";
|
|
}
|
|
```
|
|
|
|
2. 队友收到请求后, 用 approve/reject 响应。
|
|
|
|
```java
|
|
// TeammateProtocolTool - 队友用@Tool注解响应关闭请求
|
|
@Tool(description = "Respond to a shutdown request")
|
|
public String shutdownResponse(
|
|
@ToolParam(description = "The request_id") String requestId,
|
|
@ToolParam(description = "true to approve") boolean approve,
|
|
@ToolParam(description = "Reason for decision") String reason) {
|
|
return tracker.respondToShutdown(name, requestId, approve, reason);
|
|
}
|
|
|
|
// ProtocolTracker - 更新追踪器 + 发送响应消息
|
|
public String respondToShutdown(String sender, String requestId,
|
|
boolean approve, String reason) {
|
|
var req = shutdownRequests.get(requestId);
|
|
if (req != null) {
|
|
req.put("status", approve ? "approved" : "rejected");
|
|
}
|
|
bus.send(sender, "lead", reason != null ? reason : "",
|
|
"shutdown_response",
|
|
Map.of("request_id", requestId, "approve", approve));
|
|
return "Shutdown " + (approve ? "approved" : "rejected");
|
|
}
|
|
```
|
|
|
|
3. 计划审批遵循完全相同的模式。队友提交计划 (生成 request_id), 领导审查 (引用同一个 request_id)。
|
|
|
|
```java
|
|
// ProtocolTracker - 同样的request_id关联模式，两种用途
|
|
private final ConcurrentHashMap<String, Map<String, String>> planRequests
|
|
= new ConcurrentHashMap<>();
|
|
|
|
public String reviewPlan(String requestId, boolean approve, String feedback) {
|
|
var req = planRequests.get(requestId);
|
|
if (req == null) return "Error: Unknown plan request_id '" + requestId + "'";
|
|
req.put("status", approve ? "approved" : "rejected");
|
|
bus.send("lead", req.get("from"), feedback != null ? feedback : "",
|
|
"plan_approval_response",
|
|
Map.of("request_id", requestId, "approve", approve,
|
|
"feedback", feedback != null ? feedback : ""));
|
|
return "Plan " + req.get("status") + " for '" + req.get("from") + "'";
|
|
}
|
|
```
|
|
|
|
一个 FSM, 两种用途。同样的 `pending -> approved | rejected` 状态机可以套用到任何请求-响应协议上。
|
|
|
|
## 相对 s09 的变更
|
|
|
|
| 组件 | 之前 (s09) | 之后 (s10) |
|
|
|----------------|------------------|--------------------------------------|
|
|
| Tools | 9 | 12 (+shutdown_req/resp +plan) |
|
|
| 关机 | 仅自然退出 | 请求-响应握手 |
|
|
| 计划门控 | 无 | 提交/审查与审批 |
|
|
| 关联 | 无 | 每个请求一个 request_id |
|
|
| FSM | 无 | pending -> approved/rejected |
|
|
|
|
## 试一试
|
|
|
|
```sh
|
|
cd learn-claude-code
|
|
mvn exec:java -Dexec.mainClass=io.mybatis.learn.s10.S10TeamProtocols
|
|
```
|
|
|
|
试试这些 prompt (英文 prompt 对 LLM 效果更好, 也可以用中文):
|
|
|
|
1. `Spawn alice as a coder. Then request her shutdown.`
|
|
2. `List teammates to see alice's status after shutdown approval`
|
|
3. `Spawn bob with a risky refactoring task. Review and reject his plan.`
|
|
4. `Spawn charlie, have him submit a plan, then approve it.`
|
|
5. 输入 `/team` 监控状态
