Agent Mode Deep Dive

Autonomous Coding Agent

When you toggle Agent Mode in the Composer, Cursor transforms from an editor into an autonomous coding agent. It follows a ReAct (Reasoning + Action) loop:

1. Analyze: Reads your codebase to understand architecture
2. Plan: Determines which files need changes
3. Execute: Creates/modifies files and runs commands
4. Verify: Runs tests or checks for errors
5. Iterate: If errors occur, it reads the output and fixes them

YOLO Mode

For experienced developers, YOLO Mode (Settings → Features) allows the agent to execute terminal commands without asking for approval. This eliminates the constant "Allow this command?" prompts but requires strong version control discipline.

Plan Mode

Before diving into code, toggle Plan Mode (often via Shift+Tab in the Composer input). This forces the agent to research the codebase and create a detailed plan before writing any code — preventing wasted compute on wrong approaches.

Cursor 3: Multi-Agent (2026)

The latest Cursor 3 interface supports running multiple agents in parallel across different repositories. You can spawn separate agent sessions — one for frontend, one for backend, one for tests — and they all work simultaneously.
