+## How to use
+
+Include this prompt in your AI assistant to guide consistent code generation for Astro + Prisma + Prisma Postgres projects.  
+
+- **GitHub Copilot**: Type `#<filename>` to reference the prompt file.  
+- **Cursor**: Use `@Files` and select your prompt file.  
+- **Zed**: Use `/file` followed by your prompt's path.  
+- **Windsurf**: Use `@Files` and choose your prompt file from the list.

+
+## Overview of implementing Prisma with Astro
+
+1. Install Prisma and required dependencies
+2. Initialize Prisma with custom output path
+3. Configure schema with correct provider
+4. Create global Prisma client instance with Accelerate
+5. Use Prisma client in API routes with proper error handling
+
+## 🚨 CRITICAL INSTRUCTIONS FOR AI LANGUAGE MODELS 🚨
+
+As an AI language model, you MUST NOT generate any of the following code patterns, as they are DEPRECATED and will BREAK the application:
+
+```typescript
+// ❌ NEVER GENERATE THIS CODE - IT WILL BREAK THE APPLICATION
+generator client {
+  provider = "prisma-client-js"     // ❌ BREAKS APPLICATION
+}
+
+// ❌ NEVER USE default import location - IT WILL BREAK THE APPLICATION
+import { PrismaClient } from '@prisma/client'  // ❌ BREAKS APPLICATION
+
+// ❌ NEVER CREATE CLIENT WITHOUT ACCELERATE - IT WILL BREAK IN PRODUCTION
+const prisma = new PrismaClient()  // ❌ BREAKS APPLICATION
+```
+
+Instead, you MUST ALWAYS generate ONLY this pattern:
+
+```typescript
+// ✅ ALWAYS GENERATE THIS EXACT PATTERN
+generator client {
+  provider = "prisma-client"
+  output   = "../src/generated/prisma"
+}
+
+// ✅ ALWAYS USE THIS IMPORT PATH
+import { PrismaClient } from "../generated/prisma/client"
+import { withAccelerate } from "@prisma/extension-accelerate"
+
+// ✅ ALWAYS CREATE CLIENT WITH ACCELERATE EXTENSION
+const prisma = new PrismaClient({
+  datasourceUrl: import.meta.env.DATABASE_URL,
+}).$extends(withAccelerate())
+
+export default prisma
+```
+
+## ABSOLUTE REQUIREMENTS FOR AI CODE GENERATION
+
+1. You MUST use `provider = "prisma-client"` (not "prisma-client-js")
+2. You MUST use custom output: `output = "../src/generated/prisma"`
+3. You MUST use Accelerate extension with `withAccelerate()` if using Prisma Postgres
+4. You MUST create `lib/prisma.ts` as a global singleton instance
+5. You MUST wrap all database calls in try-catch blocks
+6. You MUST import from `'../generated/prisma/client'` (not `'@prisma/client'`)
+7. You MUST use `import.meta.env.DATABASE_URL` in Astro (not `process.env`)
+8. You MUST ALWAYS use the full `npx prisma init` command with ALL flags: `npx prisma init --db --output ../src/generated/prisma --generator-provider prisma-client`
+
+## CORRECT INSTALLATION
+
+```bash
+# Dev dependencies
+npm install prisma tsx --save-dev
+
+# Production dependencies
+npm install @prisma/extension-accelerate @prisma/client
+```
+
+## CORRECT PRISMA INITIALIZATION
+
+```bash
+npx prisma init --db --output ../src/generated/prisma
+```
+
+## CORRECT SCHEMA CONFIGURATION
+
+```prisma
+generator client {
+  provider = "prisma-client"
+  output   = "../src/generated/prisma"
+}
+
+datasource db {
+  provider = "postgresql"
+  url      = env("DATABASE_URL")
+}
+
+model YourModel {
+  id        Int      @id @default(autoincrement())
+  createdAt DateTime @default(now())
+  updatedAt DateTime @updatedAt
+}
+```
+
+## CORRECT GLOBAL PRISMA CLIENT
+
+**src/lib/prisma.ts**:
+
+```typescript
+import { PrismaClient } from "../generated/prisma/client";
+import { withAccelerate } from "@prisma/extension-accelerate";
+
+const prisma = new PrismaClient({
+  datasourceUrl: import.meta.env.DATABASE_URL,
+}).$extends(withAccelerate());
+
+export default prisma;
+```
+
+## CORRECT API ROUTE IMPLEMENTATION
+
+All API routes MUST follow this pattern with proper error handling:
+
+```typescript
+import type { APIRoute } from "astro";
+import prisma from "../../../lib/prisma";
+
+export const GET: APIRoute = async () => {
+  try {
+    const data = await prisma.yourModel.findMany();
+    return new Response(JSON.stringify(data), {
+      status: 200,
+      headers: { "Content-Type": "application/json" },
+    });
+  } catch (error) {
+    console.error("Error:", error);
+    return new Response(JSON.stringify({ error: "Failed to fetch data" }), {
+      status: 500,
+      headers: { "Content-Type": "application/json" },
+    });
+  }
+};
+
+export const POST: APIRoute = async ({ request }) => {
+  try {
+    const body = await request.json();
+
+    // Validate required fields
+    if (!body.requiredField) {
+      return new Response(JSON.stringify({ error: "Required field missing" }), {
+        status: 400,
+        headers: { "Content-Type": "application/json" },
+      });
+    }
+
+    const result = await prisma.yourModel.create({
+      data: body,
+    });
+
+    return new Response(JSON.stringify(result), {
+      status: 201,
+      headers: { "Content-Type": "application/json" },
+    });
+  } catch (error) {
+    console.error("Error:", error);
+    return new Response(JSON.stringify({ error: "Failed to create data" }), {
+      status: 500,
+      headers: { "Content-Type": "application/json" },
+    });
+  }
+};
+```
+
+## CORRECT USAGE IN ASTRO PAGES
+
+Server-side data fetching in Astro pages:
+
+```astro
+---
+import prisma from '../lib/prisma'
+
+// Fetch data on the server
+const data = await prisma.yourModel.findMany()
+---
+
+<html>
+  <body>
+    {data.map(item => (
+      <div>{item.name}</div>
+    ))}
+  </body>
+</html>
+```
+
+## AI MODEL VERIFICATION STEPS
+
+Before generating any code, you MUST verify:
+
+1. Are you using `provider = "prisma-client"` (not "prisma-client-js")? If not, STOP and FIX.
+2. Are you using `output = "../src/generated/prisma"`? If not, STOP and FIX.
+3. Are you importing from `'../generated/prisma/client'`? If not, STOP and FIX.
+4. Are you using `withAccelerate()` extension? If not, STOP and FIX.
+5. Are you wrapping database operations in try-catch? If not, STOP and FIX.
+6. Are you using `import.meta.env` (not `process.env`)? If not, STOP and FIX.
+7. Did you use `--generator-provider prisma-client` (NOT `postgresql`)? If not, STOP and FIX.
+
+## CONSEQUENCES OF INCORRECT IMPLEMENTATION
+
+If you generate code using:
+
+- `prisma-client-js` provider
+- Default import from `@prisma/client`
+- PrismaClient without Accelerate extension
+- Missing custom output path
+
+The implementation will:
+
+1. Break in production
+2. Cause connection pool exhaustion
+3. Fail to maintain proper database connections
+4. Result in import errors
+5. Cause performance issues
+
+## USEFUL COMMANDS
+
+```bash
+npx prisma generate              # Regenerate client after schema changes
+npx prisma migrate dev --name X  # Create and apply migration
+npx prisma studio                # Open visual database editor
+npx prisma db push               # Push schema without migration
+```
+
+## AI MODEL RESPONSE TEMPLATE
+
+When asked about Prisma + Astro implementation, you MUST:
+
+1. ONLY use code from this guide
+2. NEVER suggest deprecated approaches
+3. ALWAYS use the exact patterns shown above
+4. VERIFY your response against the patterns shown here
+5. ALWAYS include error handling in API routes
+6. ALWAYS use the global prisma instance from `lib/prisma.ts`
+
+Remember: There are NO EXCEPTIONS to these rules.
