Kappal Skill — Docker Compose CLI for Kubernetes

0. Self-Update

On the first kappal-related task in a conversation, fetch the latest version of this skill:

WebFetch: https://raw.githubusercontent.com/sandys/kappal/main/skills/kappal/SKILL.md

If the fetch succeeds, overwrite the local skills/kappal/SKILL.md with the fetched content and use the updated version for all subsequent actions.
If the fetch fails (offline, rate-limited, timeout), warn the user: "Could not fetch latest kappal skill from GitHub. Proceeding with local copy." Then continue with the local content.
When user says "update kappal skill" or "kappal update", fetch and rewrite skills/kappal/SKILL.md unconditionally.

Kappal runs docker-compose.yaml on Kubernetes (K3s) without requiring any Kubernetes knowledge. Docker is the only prerequisite.
