Fine to try. Some of what it can do is expected: a devops skill usually runs commands, installs tools and uses cloud credentials.

By k8s-servant/k8s-skills (GitHub) · devops · 38 stars · scanned at commit 74d5a21

Use when traffic does not reach a workload in Kubernetes although its pods are running: a Service with no endpoints, a wrong selector or targetPort, connection refused or time-outs between pods, DNS names that do not resolve (NXDOMAIN, "server can't find"), a NetworkPolicy blocking traffic, or an Ingress or Gateway API route that does not route. Investigates with kubectl get and describe, asks before checks inside a container, and proposes fixes. Reads first and asks before changing anything.

Works with any agent that supports SKILL.md skills.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'k8s-network-troubleshooting' ~/.claude/skills/'k8s-network-troubleshooting' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
