1. Cursor publishes a postmortem on a year of cloud agents, citing 50M daily actions on Temporal

Cursor. Josh Ma’s May 21 writeup details five lessons from a year of running cloud agents in production, leading with a migration to Temporal for durable execution that pushed reliability past two nines and now handles more than 50 million daily actions across 7 million workflows. The post argues that as base models improve, the bottleneck shifts from prompting to environment reconstruction, so Cursor rebuilds full development environments from scratch for each run rather than reusing snapshots. It also describes decoupling the agent loop, machine state, and conversation state into separate concerns so pods can be recycled and retries handled without losing context. Source

2. Cursor’s harness roadmap targets self-healing environments and stripping deterministic glue code

Cursor. The same post lays out where the harness is heading: progressively handing agents more autonomy while deleting deterministic logic that previously wrapped tool calls, on the argument that cloud agents cannot afford blocking delays the way an in-IDE assistant can. The stated next step is self-healing environments in which the agent itself diagnoses and fixes missing secrets, broken network paths, or misconfigured dependencies before retrying, rather than failing back to a human. The framing positions Cursor’s cloud product less as a chat surface and more as a workflow runtime whose primary engineering investment is in execution durability and environment fidelity. Source
