K8s Yaml Validator

This is a read-only validation tool that runs your Kubernetes manifests through a multi-stage pipeline: yamllint for syntax, kubeconform for schema validation, and optional kubectl dry-run testing. It detects CRDs and automatically looks up their documentation via Context7 or web search so you understand custom resource requirements. The workflow is deterministic with explicit paths and document counting, designed to generate a comprehensive report with before/after fix suggestions without touching your files. Use it when you need to catch errors before applying to a cluster or when debugging manifests with custom resources. The strict report-only approach means no surprise edits, just actionable findings you can review and apply yourself.

Kubernetes YAML Validator

Overview

This skill provides a comprehensive validation workflow for Kubernetes YAML resources, combining syntax linting, schema validation, cluster dry-run testing, and intelligent CRD documentation lookup. Validate any Kubernetes manifest with confidence before applying it to the cluster.

IMPORTANT: This is a REPORT-ONLY validation tool. Do NOT modify files, do NOT use Edit tool, do NOT use AskUserQuestion to offer fixes. Generate a comprehensive validation report with suggested fixes shown as before/after code blocks, then let the user decide what to do next.
