• When designing URL structures and resource naming conventions
• When adding query parameters for filtering, sorting, or pagination
• When implementing API versioning strategies (URL path or headers)
• When defining HTTP status codes for various response scenarios
• When working on rate limiting or API middleware
• When building Bun, Express, Hono, or ASP.NET Core Web API backends
• When implementing Server Actions in Next.js for data mutations
• When configuring CORS, request size limits, or authentication middleware
