Run NVIDIA OpenShell 0.1.x — the sandboxed runtime for autonomous AI agents (gateway, per-sandbox supervisor, Landlock/seccomp/netns isolation, L7 network policy, credential placeholders via providers/profiles) — the way current practitioners do. Core knowledge: the 0.1.0 breaking cutover and which 0.0.x patterns are now wrong (inference.local, built-in profiles, --from Dockerfile builds, community base image, config v1); local gateway installs (RPM/deb/brew/snap, clean reinstall from 0.0.x)…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# OpenShell best practices (0.1.x)

Snapshot: OpenShell **0.1.7** (2026-11-03), from the v0.1.7 tag, release notes, GitHub issues
filed since 0.1.0, and practitioner write-ups (history in `references/sources.md`). OpenShell releases about
weekly and breaks things between minors — **check the installed and latest versions before
advising** (`openshell --version`, `gh release list --repo NVIDIA/OpenShell`) and read every
release note in between. When this skill and the code at the user's tag disagree, the code wins.

## Mental model

| Piece | Role |
|---|---|
| **Gateway** | Control plane (gRPC on one HTTPS port). Creates sandboxes through a compute driver (Docker, Podman, Kubernetes, VM), stores sandboxes, policies, profiles and provider secrets, authenticates users (OIDC / mTLS). The CLI and TUI are thin clients; `openshell gateway select` switches between gateways |
| **Supervisor** | One per sandbox (or a shared pool on Kubernetes). Owns the network boundary: every agent connection goes through it, it evaluates policy, terminates TLS with a per-sandbox CA, injects real credentials only at approved endpoints, and opens the upstream connection itself |

How to install

The exact contents, by fingerprint
mdr add air-gapped/skills/openshell-best-practices@sha256:3dbbf06e43592371

The line at the top of this page pins the label git:20261103.66f7896, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
