Cursor tips: getting more out of the AI code editor
Cursor's agent mode makes changes directly to your codebase, which makes it powerful and occasionally overconfident. These are habits that make the difference between a clean diff and a mess to clean up.
About Cursor
AI code editor with best-in-class agentic editing
1. Use Ask mode before Agent mode on anything you don't fully understand
Agent mode edits files directly; Ask mode talks through the change first without touching anything. Run unfamiliar or risky changes through Ask first — it catches a wrong assumption before it becomes a diff you have to unwind.
2. Reference files explicitly with @filename instead of describing them
Cursor's context retrieval is good but not psychic. Pointing it at the exact file saves a retrieval round-trip and avoids it confidently editing the wrong one.
3. Keep a rules file documenting your codebase's conventions
A project rules file (or an AGENTS.md) that states your formatting, architecture and testing conventions gets read automatically on every session — it stops the agent re-litigating the same choices, and re-explaining them yourself, over and over.
4. Review every diff that touches auth, payments or migrations
The agent sounds equally confident whether it's right or wrong. Give extra scrutiny specifically to the categories where a wrong guess is expensive to unwind.
5. Start a fresh session for a new task rather than continuing a long one
A chat that's accumulated several unrelated fixes fills the context window with noise. A clean session on a single task usually produces a better first attempt than one still dragging the last five requests behind it.
FAQ
- Is Cursor's free tier enough to actually try this?
- Yes for evaluation — enough to test agent mode on a real task before deciding whether to pay. See our free vs. paid AI agents guide for how its limits compare to the other agent tools we cover.
