Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 2 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: dl.k8s.io, kubernetes.io.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

About this skill

What it does

The k8s-yaml-validator skill validates Kubernetes YAML files against the Kubernetes schema. It checks for syntax errors, structural issues, and common configuration mistakes to ensure your deployments are correct before applying them to a cluster. This helps prevent deployment failures and ensures consistency across environments.

When to use it

  • Pre-Deployment Checks: Validate YAML files before applying them to a Kubernetes cluster to catch errors early.
  • CI/CD Pipelines: Integrate validation into your CI/CD pipelines as part of automated testing.
  • Configuration Management: Ensure consistency and correctness when managing Kubernetes configurations across multiple teams or environments.
  • Learning & Debugging: Quickly identify issues in YAML files while learning Kubernetes or troubleshooting deployment problems.

Key capabilities

  • Validates Kubernetes YAML files.
  • Checks against the official Kubernetes schema.
  • Identifies syntax and structural errors.

Example prompts

  • "Validate this k8s YAML: [paste YAML content]"
  • "Is this Kubernetes manifest valid? [paste YAML content]"
  • "Check for errors in my deployment YAML."

Tips & gotchas

  • The skill requires a basic understanding of Kubernetes YAML structure. Complex or highly customized configurations might require more specialized validation tools.
