Vue 3 Options API style (data(), methods, this context). Each reference shows Options API solution only.

AI-generated overview

Reference guidance on Vue 3 Options API style, TypeScript typing, and common pitfalls.

What it does: This skill provides best-practice guidance for writing Vue 3 components with the Options API, covering TypeScript integration and frequent mistakes. It routes specific problems to ten reference documents, such as typing props, computed return types, event handlers, and provide/inject. Each reference presents only the Options API solution. It produces explanatory guidance rather than code artifacts.
When to use it: Use it when working on Vue 3 components that use data(), methods, and this context, especially when adding TypeScript types or debugging context and lifecycle issues. It is also useful when arrow functions in methods or lifecycle hooks cause problems, or when debounced functions leak state between component instances.
Requirements: No scripts or runtime dependencies; it is instructions and reference documents only. The agent needs access to the bundled reference files.
