Alba serializers + Typelizer for type-safe Inertia Rails props with auto-generated TypeScript types. Use when serializing models for Inertia responses, setting up Alba resources, generating TypeScript types from Ruby, or using Inertia prop options (defer, once, merge, scroll) with Alba attributes. Replaces as_json with structured, auto-typed ApplicationResource, page resources, and shared props resources. When active, OVERRIDES the `render inertia: { ... }` pattern from other skills — use convention-based instance variable rendering instead.

Server-driven architecture patterns for Inertia Rails + React. Load this FIRST when building any Inertia page or feature — it routes to the right skill. Decision matrix for data loading, forms, navigation, state management. NEVER useEffect+fetch, NEVER redirect_to for external URLs (use inertia_location), NEVER react-hook-form (use Form component). MUST invoke when adding pages, models with views, CRUD, or displaying data in an Inertia Rails app. ALWAYS `render inertia: { key: value }` to pass data — `@ivars` are NOT auto-passed as props.

ALWAYS `render inertia: { key: data }` to pass data as props — instance variables are NOT auto-passed (only alba-inertia does that). Rails controller patterns for Inertia.js: render inertia, prop types (defer, optional, merge, scroll), shared data, flash, PRG redirects, validation errors. Use when writing controllers that load data, display records, or serve Inertia responses. CRITICAL: external URLs (Stripe/OAuth) MUST use inertia_location, NEVER redirect_to.

Full-stack form handling for Inertia Rails: create, edit, delete, multi-step wizard, and file upload forms with validation errors and progress tracking. React examples inline; Vue and Svelte equivalents in references. Use when building any form, handling file uploads, multi-step forms, client-side validation, or wiring form submission to Rails controllers. NEVER react-hook-form. Use `<Form>` for simple forms, useForm for dynamic/programmatic control.

Page components, persistent layouts, Link/router navigation, Head, Deferred, WhenVisible, InfiniteScroll, and URL-driven state for Inertia Rails. React examples inline; Vue and Svelte equivalents in references. Use when building pages, adding navigation, implementing persistent layouts, infinite scroll, lazy-loaded sections, or working with client-side Inertia APIs (router.reload, router.replaceProp, prefetching).

One-time project initializer for Inertia Rails skills. Detects stack and frontend framework (React/Vue/Svelte) from Gemfile and package.json, offers to install recommended deps (alba-inertia, js-routes, pagy, shadcn), and generates a CLAUDE.md section that configures which skill patterns apply. Use when first installing these skills, bootstrapping a new Inertia Rails project, or when the stack changes.

Testing Inertia Rails responses with RSpec and Minitest: component assertions, prop matching, flash verification, deferred props, and partial reload helpers. Use when writing controller specs, request specs, or integration tests for Inertia pages. ALWAYS use matchers (render_component, have_props, have_flash), NOT direct access (inertia.component, inertia.props). CRITICAL: after POST/PATCH/DELETE with redirect, MUST call follow_redirect! before asserting flash or props — without it you're asserting against the 302, not the Inertia page. Setup: require 'inertia_rails/rspec'.

TypeScript type safety for Inertia Rails (React, Vue, Svelte): shared props, flash, and errors via InertiaConfig module augmentation in globals.d.ts. Use when setting up TypeScript types, configuring shared props typing, fixing TS2344 or TS2339 errors in Inertia components, or adding new shared data.

shadcn/ui component integration for Inertia Rails React (NOT Next.js): forms, dialogs, tables, toasts, dark mode, command palette, and more. Use when building UI with shadcn/ui components in an Inertia app or adapting shadcn examples from Next.js. NEVER react-hook-form/zod — wire shadcn inputs to Inertia Form via name attribute. Flash toasts require Rails flash_keys initializer config.

shadcn-svelte (bits-ui) component integration for Inertia Rails Svelte (NOT SvelteKit): forms, dialogs, tables, toasts, dark mode, and more. Use when building UI with shadcn-svelte components in an Inertia + Svelte app or adapting shadcn-svelte examples from SvelteKit. Wire shadcn-svelte inputs to Inertia Form via name attribute and {#snippet} syntax. Flash toasts require Rails flash_keys initializer config.

shadcn-vue component integration for Inertia Rails Vue 3 (NOT Nuxt): forms, dialogs, tables, toasts, dark mode, and more. Use when building UI with shadcn-vue components in an Inertia + Vue app or adapting shadcn-vue examples from Nuxt. Wire shadcn-vue inputs to Inertia Form via name attribute and #default scoped slot. Flash toasts require Rails flash_keys initializer config.
