k8s-yaml-validator SKILL.md skillA
k8s-yaml-validator from pantheon-org/tekhne is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add pantheon-org/tekhne/k8s-yaml-validator@git:20261002.bde081dPins git:20261002.bde081d in mdr.lock. Pin the fingerprint instead.

Comprehensive toolkit for validating, linting, testing Kubernetes YAML resources. Use this skill when validating Kubernetes manifests, debugging YAML syntax errors, performing dry-run tests on clusters, working with Custom Resource Definitions (CRDs) that require documentation lookup.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Kubernetes YAML Validator ## Mindset **Mental Model**: Validation is a layered funnel—syntax → schema → cluster constraints → runtime behavior. Each layer catches different classes of errors, and a pass at one layer must never be read as a pass at the next: `yamllint` clean says nothing about schema compliance, and `kubeconform` clean says nothing about whether an admission webhook will reject the resource. You must always run every applicable layer, never stop at the first one that returns clean. The classic pitfall this catches: a manifest that is syntactically perfect and schema-valid but still gets rejected by a PodSecurity admission webhook — a gotcha that only the cluster-constraints layer can surface. **Decision Framework**: 1. **Syntax first**: Fix YAML structure before schema issues (broken YAML can't be validated) 2. **Schema second**: Verify API compliance before cluster-specific checks 3. **Cluster third**: Test against real constraints (RBAC, quotas, admission webhooks) 4. **Runtime last**: Consider how the resource behaves in production **When to use this skill**: - Before applying any YAML to a cluster (development, staging, production) …

How to install
mdr add pantheon-org/tekhne/k8s-yaml-validator@sha256:d7792725fce10dc9The line at the top of this page pins the label git:20261002.bde081d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
