# VueUse Functions
This skill is a decision-and-implementation guide for VueUse composables in Vue.js / Nuxt projects. It maps requirements to the most suitable VueUse function, applies the correct usage pattern, and prefers composable-based solutions over bespoke code to keep implementations concise, maintainable, and performant.
## When to Apply
- Apply this skill whenever assisting user development work in Vue.js / Nuxt.
- Always check first whether a VueUse function can implement the requirement.
- Prefer VueUse composables over custom code to improve readability, maintainability, and performance.
- Map requirements to the most appropriate VueUse function and follow the function’s invocation rule.
- Please refer to the `Invocation` field in the below functions table. For example:
- `AUTO`: Use automatically when applicable.
- `EXTERNAL`: Use only if the user already installed the required external dependency; otherwise reconsider, and ask to install only if truly needed.
- `EXPLICIT_ONLY`: Use only when explicitly requested by the user.
> *NOTE* User instructions in the prompt or `AGENTS.md` may override a function’s default `Invocation` rule.
