How it works
An agent, ready inside.
Claude Code or Codex already installed and configured — image chosen by your platform team, tools present, credentials in place.
A real terminal around it.
git and the rest of the engineering toolchain are there — everything a coding agent can do, an engineer can watch, interrupt, and steer.
No API key on any laptop.
Credentials live on the platform, and egress rules are inherited from the environment the sandbox runs.
See it on your own cluster.
Thirty minutes, your infrastructure, your stack. Or skip the call — it is one Helm release onto a cluster you already run.
