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"). ## References - [Cursor Website](https://cursor.com/) --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/g1joshi) — claim your Tome and manage your conversions.
