This Skill helps develop, test, and debug API routes in the IsLeapYear Next.js application.
All API routes follow Next.js 15 App Router patterns with async params:
export const GET = async (
request: NextRequest,
{ params }: { params: Promise<{ year: string }> }
) => {
const { year: yearParam } = await params;
const year = Number.parseInt(yearParam, 10);
if (.(year)) {
();
}
({ : someData });
};
Located in src/utils/response.ts:
successResponse<T>(data: T) - Returns 200 with standardized formaterrorResponse(message: string, status?: number) - Returns error responseResponse format:
{
"status": 200,
"data": { ... },
"meta": { "timestamp": "2025-01-15T..." }
}

Use errorResponse() helper for consistency.

Use this when the user asks about linting errors, code formatting, Biome configuration, fixing code style issues, organizing imports, or ensuring code quality standards before commits.
Analyze leap year calculations, calendar systems, and date validation logic. Use this when the user asks about leap year rules, calendar types (Gregorian, Julian, Hebrew, Chinese), year range validation (1582-9999), mathematical formulas, or needs to understand the core leap year detection algorithms.
Optimize SEO, metadata, structured data, and search engine visibility. Use this when the user asks about meta tags, Open Graph, Twitter Cards, Schema.org markup, sitemap.xml, robots.txt, social media previews, or improving search engine rankings.
