Cursor Projects: a coordinator agent for months-long bodies of work

Cursor shipped Projects in beta to all users: a container for larger bodies of work (a feature, a migration, a full app) that maintains context over months. A Coordinator agent plans work, delegates to parallel implementing agents, and brings finished work back for review; it does not write code itself. A Project runs on its own cloud computer (closing the laptop does not stop it), launching local agents on demand for local testing. Files are synced across all of a project's cloud and local machines, accumulating research, artifacts, codebase knowledge and user preferences — once one agent learns how to test a service, every future agent reuses it. Coordinators can watch Slack channels, run on schedules, or follow PRs and act on signals.

Cursor has productized the manager/implementer split: the coordinator is a planning-and-delegation layer over the parallel agent fleet it already shipped, and the shared, growing context file turns one-off agent runs into a durable engineering asset. Combined with subscriptions, this is the most complete 'always-on engineering org' shipped by a dev-tool vendor — the open question is review load and cost control.
