The approach bakes Claude Code and Codex CLI into a snapshot, copies it across AWS regions, and publishes a manifest JSON so Mission Control always pulls the latest image. A GitHub Action triggers the build on each tag release. The result cuts sandbox startup from several minutes down to 30–60 seconds. Additional features include automatic credential forwarding, a 30-minute idle timer that pauses the EC2 instance to save costs, and the ability to run long-running AI refactoring tasks in the cloud without tying up a local machine. ## Full article daily.dev links to this article rather than hosting it.
