最近发现了一个极简 Claude Code 的文档：learn.shareai.run/en/s03/
其中有一个实用技巧：如何在适当时机提醒 AI 更新 TodoList？ 文档中的做法是：当连续三次工具调用都没有触发 todo 更新操作时，在 Function Call 返回值的第一个位置插入一条提醒：
xml
<reminder>Update your todos.</reminder>对应的 Python 实现如下：
python
if rounds_since_todo >= 3 and messages:
last = messages[-1]
if last["role"] == "user" and isinstance(last.get("content"), list):
last["content"].insert(0, {
"type": "text",
"text": "<reminder>Update your todos.</reminder>",
})那么在 Spring AI 中能否实现同样的效果？经过一番研究，答案是可以的。本文记录实现过程。

定义 TodoList Tool
首先需要定义供 LLM 调用的 Tool。以下是完整实现，包含读取和写入两个操作，并通过 Caffeine 本地缓存按会话隔离存储：

@Component
public class TodolistTools extends BaseTools {
private static final int MAX_TODOS = 20;
private static final Set<String> VALID_STATUSES = Set.of("pending", "in_progress", "completed");
private static final Map<String, String> STATUS_MARKERS = Map.of(
"pending", "[ ]",

);
private record TodoItem(String id, String text, String status) {}
private static final Cache<String, List<TodoItem>> TODOLIST_CACHE = Caffeine.newBuilder()
.maximumSize(1000)
.expireAfterWrite(Duration.ofMinutes(30))
.build();
@Tool(description = "Update task list. Track progress on multi-step tasks. Pass the full list of items each time (replaces previous list). " +
"Each item must have id, text, status. Status: pending, in_progress, completed. Only one item can be in_progress."
)
public String todoUpdate(
@ToolParam(description = "Full list of todo items. Each item: id (string), text (string), status (pending|in_progress|completed).")
List<Map<String, Object>> items,
ToolContext toolContext
) {
try {
String conversationId = ConversationUtils.getToolsContext(toolContext).appId();
if (items == null || items.isEmpty()) {
TODOLIST_CACHE.invalidate(conversationId);
return "No todos.";
}
if (items.size() > MAX_TODOS) {
return "Error: Max " + MAX_TODOS + " todos allowed";
}
List<TodoItem> validated = validateAndConvert(items);
TODOLIST_CACHE.put(conversationId, validated);
return render(validated);
} catch (IllegalArgumentException e) {
return "Error: " + e.getMessage();
}
}
private List<TodoItem> validateAndConvert(List<Map<String, Object>> items) {
int inProgressCount = 0;
List<TodoItem> result = new ArrayList<>(items.size());
for (int i = 0; i < items.size(); i++) {
Map<String, Object> item = items.get(i);
String id = String.valueOf(item.getOrDefault("id", String.valueOf(i + 1))).trim();
String text = String.valueOf(item.getOrDefault("text", "")).trim();
String status = String.valueOf(item.getOrDefault("status", "pending")).toLowerCase();
if (StringUtils.isBlank(text)) {
throw new IllegalArgumentException("Item " + id + ": text required");
}
if (!VALID_STATUSES.contains(status)) {
throw new IllegalArgumentException("Item " + id + ": invalid status '" + status + "'");
}
if ("in_progress".equals(status)) {
inProgressCount++;
}
result.add(new TodoItem(id, text, status));
}
if (inProgressCount > 1) {
throw new IllegalArgumentException("Only one task can be in_progress at a time");
}
return result;
}
@Tool(description = "Read the current todo list for this conversation. Use this to check progress and see what tasks remain.")
public String todoRead(ToolContext toolContext) {
String conversationId = ConversationUtils.getToolsContext(toolContext).appId();
List<TodoItem> items = TODOLIST_CACHE.getIfPresent(conversationId);
return items == null || items.isEmpty() ? "No todos." : render(items);
}
private String render(List<TodoItem> items) {
if (items == null || items.isEmpty()) {
return "No todos.";
}
StringBuilder sb = new StringBuilder("\n\n");
for (TodoItem item : items) {
String marker = STATUS_MARKERS.getOrDefault(item.status(), "[ ]");
sb.append(marker).append(" #").append(item.id()).append(": ").append(item.text()).append("\n\n");
}
long done = items.stream().filter(t -> "completed".equals(t.status())).count();

return sb.append("\n\n").toString();
}
@Override
String getToolName() { return "Todo List Tool"; }
@Override
String getToolDes() { return "Read and write task todo lists to track progress"; }
}问题分析：为什么不能在普通 Advisor 中拦截工具调用？
通过阅读源码 org.springframework.ai.minimax.MiniMaxChatModel#stream 可以发现，框架内部会在 ChatModel 层直接执行 Tool 调用，而不是将其透传给 Advisor 链。核心执行逻辑如下：
java
// Tool 调用的核心逻辑，如下：
Flux<ChatResponse> flux = chatResponse.flatMap(response -> {
if (this.toolExecutionEligibilityPredicate.isToolExecutionRequired(requestPrompt.getOptions(), response)) {
// FIXME: bounded elastic needs to be used since tool calling
// is currently only synchronous
return Flux.deferContextual(ctx -> {
ToolExecutionResult toolExecutionResult;
try {
ToolCallReactiveContextHolder.setContext(ctx);
toolExecutionResult = this.toolCallingManager.executeToolCalls(prompt, response);
}
finally {
ToolCallReactiveContextHolder.clearContext();
}
return Flux.just(ChatResponse.builder().from(response)
.generations(ToolExecutionResult.buildGenerations(toolExecutionResult))
.build());
}).subscribeOn(Schedulers.boundedElastic());
}
return Flux.just(response);
})
.doOnError(observation::error)
.doFinally(signalType -> observation.stop())
.contextWrite(ctx -> ctx.put(ObservationThreadLocalAccessor.KEY, observation));
这意味着，如果我们在外层 Advisor 中尝试拦截 tool_call，此时工具已经执行完毕，并且无法识别到工具调用。所以我准备使用我自己写的 MiniMaxChatModel 覆盖掉这个源码的逻辑，之后再 Advisor 接管这个 Tool 执行。
验证思路：能否通过 Advisor 接管工具执行？
我们需要在自己的项目目录创建一个 org.springframework.ai.minimax.MiniMaxChatModel 具体文件内容可以访问 www.codecopy.cn/post/7lonmm 获取完整的代码。详细代码位置如下图所示：
这样写好之后就可以让工具调用信号透传到 Advisor 层，判断是否有 Tool 调用。验证用的 Advisor 如下：
java
@Slf4j
public class FindToolAdvisor implements StreamAdvisor {
@Override
public Flux<ChatClientResponse> adviseStream(ChatClientRequest chatClientRequest, StreamAdvisorChain streamAdvisorChain) {
return Flux.deferContextual(contextView -> {
log.info("Advising stream");
return streamAdvisorChain.nextStream(chatClientRequest).doOnNext(streamResponse -> {
boolean hasToolCalls = streamResponse.chatResponse().hasToolCalls();
log.info("Found tool calls: {}", hasToolCalls);
});
});
}
@Override
public String getName() { return "FindToolAdvisor"; }
@Override
public int getOrder() { return 0; }
}
java
@Component
public class StreamApplication implements CommandLineRunner {
@Resource
private ChatModel chatModel;
@Override
public void run(String... args) throws Exception {
ChatClient chatClient = ChatClient.builder(chatModel)
.defaultTools(FileSystemTools.builder().build())
.defaultAdvisors(new FindToolAdvisor())
.build();
ChatClient.StreamResponseSpec stream = chatClient.prompt("""
帮我写一个简单的 HTML 页面，路径是 E:\TEMPLATE\spring-skills 不超过 300 行代码
""").stream();
stream.content().subscribe(System.out::println);
}
}配置文件：

改造项目：实现 ExecuteToolAdvisor
参考 Spring AI 社区中一个尚未合并的 PR（#5383），我们实现了 ExecuteToolAdvisor，主要做了两件事：
- 工具调用 JSON 格式容错：捕获 JSON 解析异常，最多重试 3 次再抛出，提升大模型调用 Tool 时格式不规范的容错能力。
- TodoList 提醒注入 ：连续 3 次工具调用均未触发
todoUpdate时，在ToolResponseMessage的第一个位置注入提醒，引导 AI 及时更新任务列表。
⚠️ 注意
order顺序 ：由于该 Advisor 接管了工具执行，它的order值应尽量大（即靠后执行）。若order较小，可能导致后续 Advisor 的doFinally在每次工具调用时都被触发（比如后面的 buildAdvisor、versionAdvisor 只需要执行一次），而非在整个对话结束时触发一次。本实现中使用Integer.MAX_VALUE - 100。
