Add article: NVIDIA OpenShell — The Sandbox Your AI Agents Should Be Running In

[Copilot]

New article covering NVIDIA OpenShell (GTC 2026), the kernel-level policy-driven sandbox runtime for autonomous AI agents, and Hector's upstream contribution adding GitHub Copilot CLI as a first-class agent provider.

Article content

• What OpenShell enforces — four protection domains at OS level: Landlock LSM filesystem isolation, OPA-evaluated network proxy (deny-by-default), seccomp BPF syscall filtering, and private inference routing that strips caller credentials before LLM API calls
• Policy-as-code — declarative YAML policies that hot-reload on running sandboxes; version-controlled, diff-reviewable governance
• Hector's contribution (feat(providers): add GitHub Copilot CLI agent provider NVIDIA/OpenShell#476) — Copilot CLI agent provider: credential discovery from COPILOT_GITHUB_TOKEN/GH_TOKEN/GITHUB_TOKEN, dual-form command detection (copilot binary + gh copilot extension), scoped network policy for *.githubcopilot.com inference endpoints
• Layer 0 framing — positions OpenShell beneath the existing hooks/gates enforcement stack, with a comparison table and internal links to related agentic DevOps articles
• draft: true

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/htekdev/gh-hookflow/releases/latest
  • Triggering command: /usr/bin/gh gh extension install htekdev/gh-hookflow (http block)
• telemetry.astro.build
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node /home/REDACTED/work/htek-dev-site/htek-dev-site/node_modules/.bin/astro build (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
