 The CLI resolves community names against the [OpenShell Community](https://github.com/NVIDIA/OpenShell-Community) catalog, pulls the bundled Dockerfile and policy, builds the image locally, and creates the sandbox. For the full catalog and how to contribute your own, refer to [Community Sandboxes](/sandboxes/community-sandboxes).

 | What you can change | Set `tls: skip` on an endpoint to disable TLS detection and termination for that endpoint. Use this for client-certificate mTLS to upstream or non-standard binary protocols. |
 | Risk if relaxed | `tls: skip` disables credential injection and L7 inspection for that endpoint. The proxy relays encrypted traffic without seeing the contents. |
 | Recommendation | Use auto-detect (the default) for most endpoints. Use `tls: skip` only when the upstream requires the client's own TLS certificate (mTLS) or uses a non-HTTP protocol. |
