Windsurf Cascade Agent: Visual Code Generation
Cascade Agent is Windsurf's flagship feature—an AI agent that visually plans and generates code across multiple files. Unlike text-based AI coding tools, Cascade shows you exactly what it's going to build before generating code.
How Cascade Agent Works
- 1You Describe the Feature: Provide a natural language prompt
Example: "Add user authentication with JWT tokens"
- 2Cascade Creates a Visual Plan: Shows file structure and implementation approach
Visual tree showing: API routes → Database schema → Frontend components → Types
- 3You Review and Approve: Modify the plan before code generation
Add/remove files, change approach, specify requirements
- 4Cascade Generates Code: Creates all files with production-ready code
All files generated simultaneously with proper dependencies
- 5Visual Code Review: Review changes with side-by-side diff view
See exactly what changed, why, and AI's reasoning
The visual planning step is what sets Cascade apart. You see exactly what will be created before any code is generated, allowing you to catch issues early and guide the AI toward your preferred approach.
