How does this skill help with air-gapped environments?

It enforces the use of global registry overrides via .Values.global.image.registry, allowing you to easily redirect all image pulls to a local mirror without modifying individual templates.

How can I validate my Helm charts using this skill?

The skill provides standardized workflows for using 'helm lint', 'helm template', and the 'chart-testing' (ct) tool to automate installation, linting, and upgrade checks.

Does this skill support multi-chart management?

Yes, it includes specialized best practices and usage patterns for Helmfile to manage complex, multi-chart deployments and environment-specific overrides declaratively.

What naming conventions does this skill recommend?

It enforces lowercase alphanumeric names with dashes, prohibits underscores and dots, and ensures all templates are properly namespaced to avoid collisions.
