Author and edit kitsoki stories — the YAML state machines under `stories/<name>/`. Use when the user wants to add or modify a room, intent, transition, effect, host call, world var, view, prompt, flow fixture, import, exit, or phase template. Covers YAML shape, effect/host vocabulary, typed view elements, style guide, load-time invariants, and the authoring loop. For "this room misbehaves / bounced to idle" reach for `kitsoki-debugging` instead.
