Use whenever working with tina4-js — the lightweight reactive frontend framework. Trigger on any mention of tina4-js, tina4 signals, persistent signals, persist(), Tina4Element, tina4 html tagged templates, tina4 routing, tina4 WebSocket client, tina4 API client, or persistent storage of UI preferences. Also trigger when the user is building a client-rendered frontend for a Tina4 backend, or when they're working with signals, Web Components, reactive templates, islands architecture, or persisted state in a tina4-js project. If the working directory contains tina4-js code (imports from 'tina4js'), use this skill for all frontend tasks.
