Direct answer: use isolated subagents for independent checks, not automatic approval
Cursor says its subagents can run on their own virtual machines. Each receives an isolated copy of the project and a clean context in its own cloud environment. That makes the feature useful for testing changes away from the parent agent’s working environment or for investigating independent fixes without collisions. It does not, by itself, prove that a release is correct, secure or ready for production.
The durable implementation pattern is therefore simple: the parent task produces a candidate change, isolated subagents attempt defined checks, and a named human owner reviews their evidence before accepting or rejecting the release. CreatikLab treats isolation as a way to improve test independence, not as a substitute for specifications, deterministic automation or accountable approval. Cursor does not specify performance guarantees, universal availability beyond the described cloud-agent context, security certification for each generated environment, or the correctness of agent conclusions.
