扩展托管代理：将大脑与双手解耦

Get started with Claude Managed Agents by following our docs.

通过遵循我们的 文档 开始使用 Claude Managed Agents。

A running topic on the Engineering Blog is how to build effective agents and design harnesses for long-running work. A common thread across this work is that harnesses encode assumptions about what Claude can’t do on its own. However, those assumptions need to be frequently questioned because they can go stale as models improve.

Engineering Blog 上一个持续的话题是如何 构建有效代理 和 设计框架 用于 长时间运行的工作。这项工作中的一个共同线索是，框架编码了关于 Claude 无法自行完成的操作的假设。然而，这些假设需要经常被质疑，因为随着模型改进，它们可能会 过时。

As just one example, in prior work we found that Claude Sonnet 4.5 would wrap up tasks prematurely as it sensed its context limit approaching—a behavior sometimes called “context anxiety.” We addressed this by adding context resets to the harness. But when we used the same harness on Claude Opus 4.5, we found that the behavior was gone. The resets had become dead weight.

作为一个例子，在之前的工作中我们发现，Claude Sonnet 4.5 会因为感觉到其上下文限制即将接近而过早结束任务——这种行为有时被称为“context anxiety”。我们通过在 harness 中添加上下文重置来解决这个问题。但当我们在 Claude Opus 4.5 上使用相同的 harness 时，我们发现这种行为消失了。重置变成了多余的负担。

We expect harnesses to continue evolving. So we built Managed Agents: a hosted service in the Claude Platform that runs long-horizon agents on your behalf through a small set of interfaces meant to outlast any particular implementation—including the ones we run today.

我们预计 harnesses 会继续演进。因此我们构建了 Managed Agents：Claude Platform 中的托管服务，它代表您通过一小组旨在超越任何特定实现的接口——包括我们今天运行的那些——运行长时程代理。

Building Managed Agents meant solving an old problem in computing: how to design a system for “programs as yet unthought of.” Decades ago, operating systems solved this problem by virtualizing hardware into abstractions—process, file—general enough for programs that didn't exist yet. The abstractions outlasted the hardware. The read() command is agnostic as to whether it’s accessing a disk pack from the 1970s or a modern SSD. The abstractions on top stayed stable while the implementations underneath changed freely.
