The instructions your model reads when the skill loads.
When creating a new API endpoint:
// app/api/[resource]/route.ts
import { NextRequest, NextResponse } from 'next/server';
import { z } from 'zod';
const RequestSchema = z.object({
// Define your schema
});
export async function GET(request: NextRequest) {
try {
const { searchParams } = new URL(request.url);
// Implementation
return NextResponse.json({ data }, { status: 200 });
} catch (error) {
console.error('[API] Error:', error);
return NextResponse.json(
{ error: 'Internal server error' },
{ status: 500 }
);
}
}
export async function POST(request: NextRequest) {
try {
test cases passed, vs 18 / 22 without
