Cursor
Overview
Cursor is an AI-assisted coding environment that can speed up code navigation, editing, and iteration.
Why It Matters
It helps when you need fast local context, but the generated change still needs the same engineering judgment.
Core Concepts
- Use it for speed.
- Verify edits before committing.
- Keep context grounded in the repo.
Mental Models
The editor is a multiplier, not a replacement for understanding.
Best Practices
- Ask for small, scoped changes.
- Review diff carefully.
- Keep the source of truth in the repo.
Common Mistakes
- Accepting broad refactors without review.
- Losing track of what changed.
- Letting the tool dictate architecture.
Trade-offs
Cursor can accelerate routine edits, but it can also make mistakes feel deceptively smooth.
Decision Framework
| Use Cursor for | Not ideal for |
|---|---|
| Local edits | Unreviewed critical logic |
| Navigation | Blind architecture changes |
Examples
- Use it to rename a prop across related files.
Checklists
- Did I inspect the final diff?
- Do I understand every changed file?
- Is the output aligned with the repo patterns?
Senior Engineer Notes
Senior engineers use AI editors with the same skepticism they apply to every automated suggestion.
