Helm Chart Validator & Analysis Toolkit

Overview

This skill provides a comprehensive validation and analysis workflow for Helm charts, combining Helm-native linting, template rendering, YAML validation, schema validation, CRD documentation lookup, and security best practices checking.

IMPORTANT: This validator is read-only by default. It analyzes charts and proposes improvements. Only modify files when the user explicitly asks to apply fixes.

Trigger Cases

Use this skill when one or more of these top cases apply:

• The user asks to validate, lint, check, test, or troubleshoot a Helm chart
• Helm templates fail to render, lint, or produce valid Kubernetes YAML
• A pre-deployment quality gate is needed (schema, dry-run, security checks)
• CRD resources are present and their spec fields must be verified against docs
• The user wants a severity-based validation report with proposed remediations
