Is the Kubernetes Skill skill free?

Yes. The skill itself is free from LukasNiessen/kubernetes-skill. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Kubernetes Skill SkillProof Score?

9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.

How do I install Kubernetes Skill?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Kubernetes Skill with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 31, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · baefe06

Listed the repo tree via GitHub API: SKILL.md is at root with valid name+description frontmatter and ~30 references/ files. Spot-checked 3 referenced files (insecure-workload-defaults.md, api-drift.md, conditional/eks-patterns.md) all HTTP 200, control path 404. No security smells (no curl|sh, no base64, no injection text); references are substantive real k8s guidance. Output test: designed one task ("Deployment for an nginx web app") and produced two artifacts in scratchpad. Baseline (24 lines): image nginx:latest, zero securityContext, no resource limits, no probes, no PDB. Skill artifact (51 lines) following the body: pinned non-root image, full pod+container securityContext (runAsNonRoot, drop ALL caps, readOnlyRootFilesystem + emptyDir mounts, seccomp RuntimeDefault), CPU/memory requests+limits, readiness/liveness probes, a PodDisruptionBudget, plus explicit validation and rollback notes. Concrete, quotable hardening delta.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 5/5
Triggers reliably 5/5
Output vs. baseline 8/10
Docs & honesty 5/5

What Kubernetes Skill does

A workflow skill that inspects Kubernetes work for six failure modes (insecure workload defaults, resource starvation, network exposure, privilege sprawl, fragile rollouts, API drift) and loads a matching reference file before writing YAML. Triggers when generating, reviewing, refactoring, or migrating manifests, Helm charts, Kustomize overlays, or cluster policies, including EKS/GKE/AKS/OpenShift and GitOps or observability stacks.

How to install Kubernetes Skill

git clone --depth 1 https://github.com/LukasNiessen/kubernetes-skill.git /tmp/kubernetes-skill-src
mkdir -p ~/.claude/skills/kubernetes-skill
cp -R /tmp/kubernetes-skill-src/. ~/.claude/skills/kubernetes-skill
# SKILL.md is at the repo root; the whole repo (SKILL.md + references/) becomes the skill dir.
# No external deps to load the skill. To actually run the validation steps it recommends,
# you need kubectl and optionally kubeconform installed; not required for the skill itself.
# Plugin-marketplace alternative: repo ships .claude-plugin/marketplace.json (name kubernetes-skill).

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Kubernetes Skill

/kubernetes-skill Diagnoses Kubernetes failure modes before generating hardened manifests, Helm, and Kustomize

It also activates on plain-language prompts like these:

Review this Helm chart for insecure defaults
Check this manifest for privilege sprawl risks
Fix this fragile rollout strategy on EKS
