## One-line Takeaway

Memory 评估应衡量 Agent 是否因经验而更会执行流程，而不是只测试远距离事实召回。

## What They Built or Claimed

Microsoft 发布 STATE-Bench，一个开源、memory-agnostic benchmark，用现实企业任务评估 Agent 是否能通过经验改进。

## Technical Signals

- architecture: 多轮对话 loop + stateful environment + deterministic assertions。
- tool use: 任务涉及查询、校验策略、计算费用、确认并执行。
- memory: bring-your-own-memory 接口。
- evaluation: 450 个任务，覆盖 travel、customer support、shopping。
- safety: 状态改变任务会带来真实成本，强调流程合规。
- deployment: open-source benchmark。
- data: 预填充数据库和用户模拟器。

## Evidence Quality

官方开源博客，包含任务数、领域、评估 loop 和 GitHub 入口，证据强。

## Gaps for Us

- 可以基于 STATE-Bench 思路做一个小型企业流程 Agent eval。
