YAML Master

Proactive YAML intelligence: validate syntax, enforce consistent formatting, and keep configuration files schema-correct (Kubernetes, GitHub Actions, Docker Compose, and similar).

Overview

This skill activates when working with .yml/.yaml files to detect structural issues early (indentation, anchors, type mismatches), and to produce safe, minimal edits that keep CI/config tooling happy.

Prerequisites

• The YAML file(s) to inspect and their intended target (e.g., Kubernetes, GitHub Actions, Compose)
• Any relevant schema or constraints (when available)
• Permission to edit the file(s) (or to propose a patch)

Instructions

1. Parse and validate YAML syntax (identify the first breaking error and its location).
2. Normalize formatting (indentation, quoting) without changing semantics.
3. Validate structure against the target system’s expectations (keys, types, required fields).
4. Identify risky patterns (duplicate keys, ambiguous scalars, anchors used incorrectly).
