Cursor Basics
Cursor Ask vs Agent vs Composer: The Mental Model
Use Ask to understand code or plan without changes, use Agent to make multi-file changes and run commands autonomously, and use inline edit (⌘/Ctrl+K) for one focused change you're watching. "Composer" was Cursor's earlier name for multi-file editing; in current versions it has merged into the agent experience.
What's the difference between Ask, Agent, and Composer?
| Surface | Edits code? | Best for |
|---|---|---|
| Ask / Chat | No (read-only) | Understanding a codebase, planning, debugging out loud |
| Agent | Yes, multi-file + terminal | Implementing features, refactors, fixing across files |
| Inline edit (⌘/Ctrl+K) | Yes, in place | One precise change to a selection you're watching |
| Composer (legacy term) | Yes, multi-file | Folded into Agent in current Cursor — same idea |
Cursor went agent-first in its 2.x line, so older tutorials that treat "Composer" as a separate mode are stale. Today the multi-file editing experience lives inside the Agent. Treat "Composer" as a synonym for agent-driven editing.
Which one should I use for a given task?
- 1Just need to understand or plan? → Ask (no risk, no diffs to review).
- 2One small, known change in a file you have open? → Inline edit (⌘/Ctrl+K).
- 3A change that spans files, or needs commands run? → Agent.
- 4Big or risky task? → Ask the Agent to plan first, review the plan, then let it execute.
Why do people find these modes confusing?
Three reasons: the names overlap, Cursor renamed and merged modes across versions, and beginners reach for the Agent for everything — including questions where Ask would be safer and faster. The fix is the decision model above: match the surface to the task's blast radiusHow much breaks if a change goes wrong; the scope of potential damage..
Frequently asked questions
Is Composer gone in Cursor?
The standalone "Composer" branding has been absorbed into the Agent in current versions. The capability — coordinated multi-file edits — is still there; it's just part of the agent experience now.
Can the Agent run terminal commands?
Yes. The Agent can run commands (installing packages, running tests) and apply multi-file edits, then surface diffs and command output for you to approve.
Is Ask mode safe to use on any repo?
Yes — Ask is read-only. It explains and answers without changing files, which makes it the safe default for exploring an unfamiliar codebase.
