Core Concepts

Flow Mode

Flow mode is Windsurf's signature feature. It maintains persistent context about your conversation and codebase, enabling natural back-and-forth collaboration without re-explaining context.

Codebase Indexing

Windsurf automatically indexes your codebase to provide context-aware suggestions. This enables:

• Understanding project structure and conventions
• Suggesting code that follows existing patterns
• Answering questions about your specific codebase

Examples

Conversational Refactoring

/flow
Refactor this authentication module to use a more secure approach

Code Generation

/flow
Create a REST API endpoint for user registration with validation
