Lessons from Building Cloud Agents

构建云端智能体的经验总结

Cursor summarizes lessons from building cloud agents: after migrating to Temporal, reliability rose above 99.9%, and the platform processes more than 50 million operations per day.

Why it matters: HKR-H/K/R all pass: Cursor is central to coding agents, and the post gives Temporal, 99.9%+ reliability, and 50M daily operations. Not a launch, so it stays at low-end featured.

Take

Cursor’s useful claim is that cloud-agent quality is now an environment problem, not a model problem. The hard evidence is operational: after moving to Temporal, reliability is above 99.9%, and the platform handles over 50 million operations per day. That is more convincing than another “smarter agent” demo, because long coding tasks fail on dependencies, credentials, network rules, and VM state before they fail on reasoning.

I’ve always thought the split in coding agents is not the chat surface. It is whether the product can recreate a developer’s machine. Cursor names dedicated VMs, hibernate/resume, VM image forks, secret redaction, network policies, and credential management. That is basically enterprise IT for agents. GitHub Copilot Workspace and Devin hit the same wall; Cursor is just saying the ugly part out loud.
