Cursor launches Projects: one coordinator agent orchestrating thousands of sub-agents for months
xiaohu · x · 2026-09-12
Cursor has launched Projects (beta, rolling out to all users) for tackling large chunks of work—a feature, a migration, or a full app—maintaining shared context over months.
- How it works: You talk to a single coordinator agent that plans and delegates but never writes code itself. It spawns and manages any number of parallel sub-agents on demand—one user's Project ran over a thousand.
- Cloud-native: Each Project gets its own cloud machine, so work continues with your laptop closed; when local testing is needed, the coordinator spins up a local agent on your machine.
- Triggered work: Projects subscribe to Slack channels, schedules, or your PRs, acting on signals without prompting.
- Shared context: A synced set of files across all cloud and local machines stores research, codebase knowledge, and your preferences, so later agents reuse what earlier ones figured out.
Cursor's earlier multi-agent experiment backs the design: rewriting SQLite from an 835-page manual, the old approach sat near 0% test pass after two hours, while the new planner/worker split passed 80% of tests in four hours (per Cursor's own setup). Staff demoed it as moving from one-question-one-answer chat to collaborating with an autonomous coworker.
