Cursor

The AI code editor that understands your entire repository

Cursor is a VS Code fork with deeply embedded AI that can read, write, and refactor code across your entire codebase — not just the open file. Its Composer mode lets you describe a feature in plain English and watch it scaffold files, update imports, and write tests automatically. It's the go-to choice for developers who want AI to act as a true coding partner rather than an autocomplete engine.

Best for

Building full features from natural language descriptions

Refactoring large codebases with cross-file context awareness

Debugging errors with full stack trace and codebase context

Learning unfamiliar codebases by asking questions about structure

Prompt tips for Cursor

#1

Use @ mentions (e.g., @filename.ts) to pin specific files into context before asking questions

#2

Start Composer prompts with 'Without breaking existing functionality, add...' to prevent regressions

#3

Describe the expected behavior and the actual behavior separately when asking for bug fixes

#4

Use 'Follow the patterns in @existingFile.ts' to ensure new code matches team conventions

Sample prompts

Using @authService.ts as a reference, add a refreshToken() method to @userService.ts. It should silently refresh the JWT if it expires within 5 minutes and update the cookie. Write unit tests in @userService.test.ts.
Look at the entire @/components folder and identify any components that re-render unnecessarily due to missing React.memo or useMemo. List them with the specific prop or state causing the issue.
I'm getting this error in production: [paste stack trace]. Search the relevant files in my codebase, identify the root cause, and provide a fix with an explanation of why it happens.

Pros & cons

Pros

  • Codebase-wide context means AI understands how files relate to each other
  • Composer can scaffold multi-file features in a single instruction
  • Built on VS Code so all existing extensions and keybindings work

Cons

  • Context window limits mean very large monorepos may require careful file selection
  • Subscription cost adds to existing IDE tooling budget
