⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 20, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
Pure prose style guide, no scripts. Asked to template a container image block both ways: the baseline emitted a flat repository:tag; following the skill produced a $registry := .image.registry | default .global.image.registry | default "docker.io" override plus namespaced defines and the standard app.kubernetes.io label set — a concrete air-gapped-ready delta. helm binary was absent so lint could not be run; the improvement is in generated content, not measured by execution.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 7/10
- Docs & honesty 5/5
What Helm Charts Style Guide does
A style-guide skill that injects standardized Helm chart conventions when you author or review charts: global.image.registry overrides for air-gapped registries, namespaced helper templates, the recommended app.kubernetes.io label set, RBAC/ServiceAccount separation, and fixed-tag image rules. Triggers on Helm, Chart.yaml, values.yaml, helmfile, or Kubernetes manifest templating.
How to install Helm Charts Style Guide
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
