 - `inertia-vue-development` — Develops Inertia.js v2 Vue client-side applications. Activates when creating Vue pages, forms, or navigation; using <Link>, <Form>, useForm, or router; working with deferred props, prefetching, or polling; or when user mentions Vue with Inertia, Vue pages, Vue forms, or Vue navigation.
 - `tailwindcss-development` — Always invoke when the user's message includes 'tailwind' in any form. Also invoke for: building responsive grid layouts (multi-column card grids, product grids), flex/grid page structures (dashboards with sidebars, fixed topbars, mobile-toggle navs), styling UI components (cards, tables, navbars, pricing sections, forms, inputs, badges), adding dark mode variants, fixing spacing or typography, and Tailwind v3/v4 work. The core use case: writing or fixing Tailwind utility classes in HTML templates (Blade, JSX, Vue). Skip for backend PHP logic, database queries, API routes, JavaScript with no HTML/CSS component, CSS file audits, build tool configuration, and vanilla CSS.
 - `fortify-development` — ACTIVATE when the user works on authentication in Laravel. This includes login, registration, password reset, email verification, two-factor authentication (2FA/TOTP/QR codes/recovery codes), profile updates, password confirmation, or any auth-related routes and controllers. Activate when the user mentions Fortify, auth, authentication, login, register, signup, forgot password, verify email, 2FA, or references app/Actions/Fortify/, CreateNewUser, UpdateUserProfileInformation, FortifyServiceProvider, config/fortify.php, or auth guards. Fortify is the frontend-agnostic authentication backend for Laravel that registers all auth routes and controllers. Also activate when building SPA or headless authentication, customizing login redirects, overriding response contracts like LoginResponse, or configuring login throttling. Do NOT activate for Laravel Passport (OAuth2 API tokens), Socialite (OAuth social login), or non-auth Laravel features.
-- `project-request-validation-style` — Always activate for this project when changing Laravel controllers or FormRequest classes. Use dedicated FormRequest classes for controller validation, access validated data through `$validated = $request->validated();` plus `Arr::get(...)`, avoid request helper extraction like `boolean()/integer()/string()`, and do not add custom single-field getter methods on FormRequest classes.
