Inertia Rails Project Setup

Detect stack, offer recommended deps, generate CLAUDE.md configuration.

Run once per project. Re-run when the stack changes.

NEVER:

• Run setup without inertia_rails gem in Gemfile — all skills assume it exists. If missing, tell the user to install it first.
• Overwrite existing ## Inertia Rails Stack in CLAUDE.md without reading it — the user may have manual customizations. Replace only the auto-generated block.
• Add @/ resolve aliases to vite.config.ts — vite-plugin-ruby already provides them. Only add to tsconfig.json.
• Recommend alba-inertia if the project uses jbuilder AND the user hasn't expressed interest in switching — suggest it, but don't push. You CAN still suggest it if the project has blueprinter (alba is a direct upgrade path).
• Generate CLAUDE.md blocks for skills the user doesn't have installed — saying "alba-inertia skill does NOT apply" is correct; saying "use alba-inertia" when the gem is absent is wrong.

Step 1: Detect Current Stack

Read Gemfile (NOT Gemfile.lock) and package.json and check for:

Step 2: Recommend Missing Deps

Present detected stack, then offer deps that unlock skill features but aren't installed yet. Use AskUserQuestion with multiSelect for the recommendations.

Only recommend what's missing. Skip anything already detected in Step 1.

Do NOT recommend gems the user clearly chose alternatives for (e.g., don't suggest Pagy if Kaminari is present, you can still suggest alba if the project has jbuilder or blueprinter).

Step 3: Install Opted-In Deps

Post-install scaffolding per dep:

1. alba-inertia — also scaffold ApplicationResource:

   app/resources/application_resource.rb

class ApplicationResource

  include Alba::Resource
  helper Typelizer::DSL
  helper Alba::Inertia::Resource
  include Rails.application.routes.url_helpers
end

And add Typelizer initializer:

    # config/initializers/typelizer.rb
Typelizer.configure do |config|
  config.output_dir = Rails.root.join("app/frontend/types/generated")
end

2. js-routes — run rails generate js_routes if the generator exists 3. shadcn — framework-specific init: * React: npx shadcn@latest init * Vue: npx shadcn-vue@latest init * Svelte: npx shadcn-svelte@latest init After init, add @/ resolve aliases to tsconfig.json if not present

Step 4: Generate CLAUDE.md

Find or create CLAUDE.md in the project root. If ## Inertia Rails Stack exists, replace it (up to next ## or EOF). Otherwise, append.

MANDATORY — READ ENTIRE FILE before assembling the CLAUDE.md block: references/claude-md-templates.md (~90 lines) — all template blocks for each stack variant (serialization, UI, pagination, testing, routing, authorization). Pick one block per category based on the detected stack.

Do NOT load the templates file until Step 4 — Steps 1-3 determine which blocks to use.

Troubleshooting

Step 5: Summary

Tell the user:

1. What was installed
2. Which skills are relevant to their stack (and which to ignore)
3. Review ## Inertia Rails Stack in CLAUDE.md — it takes precedence over generic examples in individual skills
