YAML Processing & Transformation

About

This skill empowers Claude with expert-level knowledge of the yq v4+ utility to handle complex YAML operations efficiently. It enables seamless querying, filtering, and in-place modification of YAML structures, which is essential for maintaining Kubernetes manifests, GitHub Actions workflows, and Helm charts. By treating YAML as structured data rather than raw text, it allows for sophisticated automation, multi-document processing, and format conversion between YAML, JSON, XML, and CSV, ensuring configuration consistency and precision across development environments.
