Best Cursor Prompt for “Build a REST API”
Cursor works best with goal-oriented prompts that include @-references to specific files and directories. As an AI code editor, it needs clear scope boundaries — what to modify and what NOT to touch — along with direct action verbs like Add, Refactor, Fix, or Extract. This free template is optimized specifically for Cursor, achieving approximately 37% token reduction compared to unoptimized prompts while producing higher quality output.

Optimized Cursor Prompt
Goal: Build a REST API with authentication and comprehensive CRUD operations for a resource. Context: Follow the patterns established in @src/api/users/ for user authentication and data handling. Refer to @src/models/resource.ts for the data structure of the resource. Use @Auth for authentication middleware implementation details. Constraints: Implement using Node.js, Express, and the Prisma ORM. Ensure all API endpoints are protected by the authentication middleware. Use TypeScript and adhere to the interfaces defined in @src/types/api.ts. Do not modify @src/config/database.ts. Implement robust error handling for all operations, returning consistent error response formats. Output: Create new API route files within @src/api/resources/. Generate corresponding unit tests in @src/tests/api/resources/. Name files using kebab-case (e.g., `resource-crud.ts`).
Why This Cursor Prompt for “Build a REST API” Works Better
When you type “Build a REST API with authentication and CRUD operations” into Cursor, it lacks structure — Cursor has to guess what format you want, how detailed to go, and what to prioritize. The optimized version removes that guesswork.
It adds @-references to specific files and directories, defines clear scope boundaries, and uses direct action verbs — giving Cursor the precise context it needs to make accurate code changes.
