FilesystemMiddleware 通过可插拔后端系统提供文件操作，解决上下文工程挑战。工具包括：ls、read_file、write_file、edit_file、glob、grep。
在 agent 状态中的临时存储 - 仅在单个会话内持久化。
import { createDeepAgent } from "deepagents";
const agent = await createDeepAgent({});
// 默认 StateBackend - 文件仅存在于会话中
import { createDeepAgent, FilesystemBackend } from "deepagents";
const agent = await createDeepAgent({
backend: new FilesystemBackend({
rootDir: ".",
virtualMode: true // 安全性：限制路径
})
});
import { createDeepAgent, StoreBackend } from "deepagents";
import { InMemoryStore } from "@langchain/langgraph";
const store = new InMemoryStore();
const agent = await createDeepAgent({
backend: (config) => new StoreBackend(config),
store
