# nuqs Type-Safe URL Search Parameters for Next.js

Implements nuqs (formerly next-usequerystate): parseAsString, parseAsInteger, parseAsArrayOf, parseAsJson, shallow navigation, debounced URL updates, and sharing state across components via URL.

## When to Invoke
Invoke this skill whenever you need to:
- use nuqs search params nextjs
- type safe url state nuqs
- debounce query param nuqs

## Execution SOP & Rules
1. Import parser: import { useQueryState, parseAsString, parseAsInteger } from 'nuqs'.
2. Initialize state: const [search, setSearch] = useQueryState('q', parseAsString.withDefault(''));
3. Configure shallow routing and history options: setSearch('val', { shallow: true, history: 'replace' }).
4. Wrap root layout with NuqsAdapter when using Next.js 15 App Router.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
