Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'k8s-coredns-troubleshooting' ] || [ -L ~/.agents/skills/'k8s-coredns-troubleshooting' ]; then echo 'A skill folder named k8s-coredns-troubleshooting already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/k8s-servant/k8s-skills' "$d" && git -C "$d" checkout --quiet '74d5a211e1bf7cd3696b4a5ba2110d24a49f3ae7' -- 'skills/k8s-coredns-troubleshooting' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/k8s-coredns-troubleshooting' ~/.agents/skills/'k8s-coredns-troubleshooting' && rm -rf "$d"; fi

For Claude Code: ln -s ~/.agents/skills/'k8s-coredns-troubleshooting' ~/.claude/skills/'k8s-coredns-troubleshooting' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
