jpc0/headless-architecture
Use this skill whenever the user discusses application architecture, clean architecture, separating business logic from UI, or cross-platform/WASM-based development. It enforces the 'Headless Core & Passive View' pattern, ensuring that the 'Core' (Business Logic) is platform-agnostic and the 'View' (UI) is a 'Humble Object' that only reflects state.
