Could you build this?

Partial While prompting LLMs to review git diffs is easy, running a fleet of parallel agents that independently reproduce and verify bugs inside isolated, transient cloud sandbox environments requires complex backend infrastructure.

What it would actually take: The architecture requires an orchestration engine (such as Temporal or Celery) managing ephemeral microVM sandboxes (via Firecracker, Modal, or E2B) that pull PR branches, build the project, and run agent-generated test scripts to deterministically verify bug hypotheses. The hard technical problems are achieving sub-second sandbox boot times, safely isolating untrusted user code, automatically resolving dependencies across arbitrary languages, and pruning false positives without incurring massive latency and compute costs.
