test-release-canary

A manual test workflow for Release Canary, an automated check of newly published OpenShell development packages before a public release. It tests installation and basic operation on macOS, Ubuntu, Fedora, and Kubernetes.

In plain words
What is it for?
Use it after a Release Dev publish, when changing the canary workflow, or when checking a release before tagging it.
Why use it?
It catches installation or startup problems in published release artifacts before they reach users.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

test-release-canary scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Test Release Canary

The Release Canary (.github/workflows/release-canary.yml) smoke-tests the artifacts a Release Dev run just published. It is the last automated checkpoint before tagging a public release: if the canary is red, the published dev artifacts do not install on a stock environment.

What the canary verifies

Job Runner Verifies
macos macos-latest-xlarge install.sh resolves the Homebrew formula, brew installs the cask, and openshell status reaches the brew-services–backed local gateway with the VM driver.
ubuntu ubuntu-latest install.sh installs the Debian package, the post-install systemd user service starts, and openshell status reaches the local gateway with the Docker driver.
fedora fedora:latest container install.sh installs the RPM packages, the local gateway starts under Podman, and openshell status succeeds.
kubernetes ubuntu-latest + kind helm install oci://ghcr.io/nvidia/openshell/helm-chart --version 0.0.0-dev succeeds in a kind cluster, the gateway pod becomes Ready, port-forward exposes 8080, and the released CLI registers the in-cluster gateway and runs openshell status against it.

All canary jobs disable anonymous OpenShell telemetry. Host package jobs inject OPENSHELL_TELEMETRY_ENABLED=false through the service environment, and the Kubernetes job installs with server.telemetryEnabled=false, so smoke traffic does not contribute to product usage metrics.

install.sh defaults to the latest tagged release — the canary is therefore checking that the most recent public release still installs, not the just-published dev build. The kubernetes job is the exception: it pins to 0.0.0-dev chart + :dev images.

The canary does not install or import @nvidia/openshell-sdk. TypeScript SDK validation lives in the TypeScript SDK branch check, including a publish dry-run. The tagged release workflow publishes the package to GitHub Packages; verify that job directly when diagnosing SDK publication failures.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

test-release-canary is a skill published in the GitHub repository NVIDIA/OpenShell (8,475 stars, last pushed today), licensed Apache-2.0. It adds 124 tokens to every session and 2,079 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
