Busabase App Creator

Create one isolated Busabase workspace and AirApp, author an installable template as files on disk, or maintain one explicitly identified existing AirApp. This skill is the single technical source of truth for AirApp modeling, the template/package format, security, runtime engineering, deployment, and maintenance; higher-level workflow skills delegate those concerns here.

The contract here is format and correctness, not taste. It says what a valid app and a valid template must contain — the resources, the manual, the runtime rules, the review gates — and stops there. Product voice, visual style, layout conventions and interaction polish belong to the user, or to a higher-level skill that layers them on top (the way kelly-app-skill-creator does); this skill must never grow opinions that would fight such a layer.

The two layers that exist today: busabase-template-creator for the public busabase/templates catalog, and kelly-app-skill-creator for mr-kelly/skills. Both call this skill for correctness and add only a publishing bar on top. Note that busabase-package-creator, busabase-skill-creator, and busabase-app-package-creator are symlinks to this skill, not separate ones — four entry names, one contract.
