Side Project Ported to Claude Managed Agents
Before joining Anthropic, I spent about two weeks working on this as a side project using Opus 4. The initial version relied on the Agent SDK, which required a constantly running process and did not perform reliably.
However, a single prompt to Opus 5.5 successfully ported the project to Claude Managed Agents, significantly improving its reliability.
