If "$ARGUMENTS" contains "add" or "install"

Guide the user through component installation:

1. Overview: Explain shadcn-svelte's copy-paste model

2. Installation commands:

   pnpm dlx shadcn-svelte@latest init
   
   # Add individual components
   pnpm dlx shadcn-svelte@latest add button
   pnpm dlx shadcn-svelte@latest add card alert dialog
   
   # Add all components
   pnpm dlx shadcn-svelte@latest add --all
   
   # List available components
   pnpm dlx shadcn-svelte@latest list

3. Component location: src/lib/components/ui/[component-name]/

4. Import patterns:

   import { Button } from "$lib/components/ui/button";
   import * as Dialog from "$lib/components/ui/dialog";

5. Next steps: Suggest form setup, theming, or specific components

If "$ARGUMENTS" contains "form" or "forms"

Walk through form creation workflow:

1. Overview: Explain shadcn-svelte forms with sveltekit-superforms

2. Required components:

   pnpm dlx shadcn-svelte@latest add form input label button
   pnpm add sveltekit-superforms zod

3. Form structure with complete example:

   <script lang="ts">
     import { superForm } from "sveltekit-superforms";
     import { zodClient } from "sveltekit-superforms/adapters";
     import { z } from "zod";
     import * as Form from "$lib/components/ui/form";
     import { Input } from "$lib/components/ui/input";
     import { Button } from "$lib/components/ui/button";
   
     const schema = z.object({
       email: z.string().email(),
       name: z.string().min(2),
     });
   
     const form = superForm(data.form, {
       validators: zodClient(schema),
     });
   
     const { form: formData, enhance } = form;
   </script>
   
   <form method="POST" use:enhance>
     <Form.Field {form} name="email">
       <Form.Control>
         {#snippet children({ props })}
           <Form.Label>Email</Form.Label>
           <Input {...props} type="email" bind:value={$formData.email} />
         {/snippet}
       </Form.Control>
       <Form.FieldErrors />
     </Form.Field>
   
     <Button type="submit">Submit</Button>
   </form>

4. Key concepts:

   • Zod schema for validation
   • superForm for form state
   • Form.Field/Form.Control structure
   • Progressive enhancement with use:enhance

5. For complex forms: Reference workflows.md for multi-step builds

6. Next steps: Table setup, dialog patterns, or theming

If "$ARGUMENTS" contains "table" or "datatable"

1. Overview: Explain TanStack Table v8 for production data tables

2. Installation:

   pnpm dlx shadcn-svelte@latest add table data-table button dropdown-menu checkbox input
   pnpm add @tanstack/table-core

3. File structure:

   routes/your-route/
     columns.ts              # Column definitions
     data-table.svelte       # Main table component
     data-table-actions.svelte
     +page.svelte

4. Key patterns:

   • Use $state for pagination, sorting, filtering
   • createSvelteTable with get accessors
   • renderComponent for interactive cells
   • renderSnippet for formatted cells

5. For complete examples: Reference shadcn-datatable.md

6. Next steps: Form integration, dialog patterns

If "$ARGUMENTS" contains "dialog" or "modal" or "drawer" or "sheet"

Explain modal/dialog/drawer patterns:

1. Overview: Dialog vs Drawer vs Sheet use cases

2. Installation:

   pnpm dlx shadcn-svelte@latest add dialog drawer button

3. Dialog example:

   <script lang="ts">
     import * as Dialog from "$lib/components/ui/dialog";
     import { Button } from "$lib/components/ui/button";
   
     let open = $state(false);
   </script>
   
   <Dialog.Root bind:open>
     <Dialog.Trigger>
       {#snippet child({ props })}
         <Button {...props}>Open Dialog</Button>
       {/snippet}
     </Dialog.Trigger>
     <Dialog.Content>
       <Dialog.Header>
         <Dialog.Title>Title</Dialog.Title>
         <Dialog.Description>Description</Dialog.Description>
       </Dialog.Header>
       <p>Content here</p>
       <Dialog.Footer>
         <Button onclick={() => (open = false)}>Close</Button>
       </Dialog.Footer>
     </Dialog.Content>
   </Dialog.Root>

4. Drawer example (mobile-friendly):

   <script lang="ts">
     import * as Drawer from "$lib/components/ui/drawer";
     import { Button } from "$lib/components/ui/button";
   </script>
   
   <Drawer.Root>
     <Drawer.Trigger>
       {#snippet child({ props })}
         <Button {...props} variant="outline">Open Drawer</Button>
       {/snippet}
     </Drawer.Trigger>
     <Drawer.Content>
       <Drawer.Header>
         <Drawer.Title>Navigation</Drawer.Title>
       </Drawer.Header>
       <nav class="flex flex-col gap-2 p-4">
         <a href="/">Home</a>
       </nav>
     </Drawer.Content>
   </Drawer.Root>

5. When to use what:

   @import "tailwindcss";
   
   @layer theme {
     :root {
       --color-background: 0 0% 100%;
       --color-foreground: 0 0% 3.6%;
       --color-primary: 0 0% 9%;
       --color-primary-foreground: 0 0% 100%;
       --color-secondary: 0 0% 96.1%;
       --color-muted: 0 0% 96.1%;
       --color-border: 0 0% 89.8%;
     }

       --color-background: 0 0% 3.6%;
       --color-foreground: 0 0% 98%;
       /* ... dark mode values */
     }
   }

4. Dark mode setup:

   pnpm i mode-watcher

   <script>
     import { modeWatcher } from "mode-watcher";
   </script>
   <div use:modeWatcher><!-- app --></div>

5. Component customization:

   • Modify directly in src/lib/components/ui/
   • Use cn() utility for class merging
   • Override with Tailwind classes

6. Next steps: Custom component creation, accessibility

If "$ARGUMENTS" contains "debug" or "error" or "troubleshoot"

Provide troubleshooting guidance:

1. Ask: "What error are you seeing?" or "What's not working?"

2. Common issues:

   Component Not Found:

   pnpm dlx shadcn-svelte@latest list    # Check installed
   pnpm dlx shadcn-svelte@latest add button --overwrite  # Reinstall

   Styling Issues:

   • Verify Tailwind v4.1 in vite.config.ts
   • Check CSS variables in src/app.css
   • Ensure @import "tailwindcss" at top

   TypeScript Errors:

   • Check path aliases in svelte.config.js
   • Verify $lib points to ./src/lib

   Import Errors:

   • Use $lib/components/ui/ not relative paths
   • Check component exists in directory

3. Provide specific fix based on error description

4. Next steps: Suggest preventive measures

If "$ARGUMENTS" contains a specific component name

Provide guidance for that specific component:
