tomevault-io Cursor AI
Cursor is a fork of VS Code with AI baked into the core. Cursor Composer (2025) acts as an autonomous engineer that can write/edit multiple files simultaneously.
When to Use
- Productivity: It is currently the fastest way to write code.
- Refactoring: "Refactor this file to use hooks" works instantly.
- Debugging: It sees your terminal errors and fixes them automatically.
Core Concepts
Composer (Cmd+I)
A multi-file editing agent. You describe a feature ("Add a login page with auth middleware") and it creates/edits all necessary files.
Tab Completion (Copilot++)
Predicts your next edit, not just your next word. It predicts cursor movement.
Context (@)
Tagging files, folders, or docs (@React Docs) to give the AI context.
Best Practices (2025)
Do:
- Use Composer: Don't just chat. Use Composer to apply edits directly.
- Add Documentation: Add external docs (
@Docs -> Add URL) so Cursor knows your specific library versions. - Review Diffs: Composer is powerful but can delete code. Always review the diffs.
Don't:
- Don't ignore the
.cursorrules: Define project-specific rules (e.g. "Always use TypeScript").
