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.

Trigger Phrases

Use this skill when prompts look like:

• "Validate this Kubernetes YAML before deploy."
• "Lint these manifests and report what is broken."
• "Check this CRD manifest and explain schema issues."
• "Run dry-run checks on this manifest."
• "Find line-level errors in this multi-document YAML."
