Cascade: The Agent Mode
What is Cascade?
Windsurf's agentic feature that handles complex tasks:
1. Define goal: "Add authentication to the API"
2. Cascade breaks down into steps
3. AI executes each step autonomously
4. Reviews changes with you
5. Applies or iterates based on feedback
How to Use Cascade:
1. Describe your feature/fix in detail
2. Cascade icon in chat
3. Review proposed changes
4. Accept or request modifications
5. Cascade applies all changes
Multi-File Refactoring
Example: Rename function across 20 files
1. Select function
2. Chat: "Rename this to getActiveUsers everywhere it's used"
3. Windsurf:
- Identifies all usages
- Previews changes
- Executes atomically
- Verifies tests still pass
Project Structure Understanding
Windsurf automatically understands:
- Dependencies: Your package.json, requirements.txt, etc.
- Architecture: How modules relate
- Patterns: Conventions used in your project
- APIs: How to integrate new code properly
Creating Projects from Description
1. File > New Project
2. Describe: "Build a React dashboard with authentication"
3. Windsurf:
- Scaffolds project structure
- Generates components
- Sets up routing
- Configures styling
- Creates sample data
Testing Capabilities
Generate Tests:
Select function > Generate Tests
Windsurf creates:
- Unit tests
- Edge cases
- Integration tests
Fix Failing Tests:
Run tests > Failures shown
Chat: "Fix these test failures"
Windsurf analyzes and fixes code
Real-time Collaboration
Share Your Workspace:
1. Create sharing link
2. Share with team
3. Others see your workspace in real-time
4. Collaborate on editing

Windsurf vs Cursor
| Aspect | Windsurf | Cursor |
|---|---|---|
| Agent mode | Yes (Cascade) | No |
| Cost | $15/month | $20/month |
| Maturity | Newer | More established |
| Performance | Excellent | Excellent |
| Team features | Growing | Basic |
| Documentation | Good | Excellent |
Integration with Existing Workflows
Import from VS Code:
1. Export VS Code profile
2. Import into Windsurf
3. Extensions and settings transfer
4. Keybindings configured
Git Integration:
Full git support:
- Staging
- Commits (with AI messages)
- Branching
- Merge conflict resolution
Troubleshooting
Agent Not Working:
- Check API key is configured
- Verify account has agent access
- Restart Windsurf
- Check internet connection
Slow Responses:
- Check codebase size (exclude node_modules)
- Use faster model for initial work
- Reduce context by selecting files
Best Practices
- Provide clear intent: Specific goals produce better results
- Review agent changes: Always review before accepting
- Use test-driven development: Tests guide agent behavior
- Break complex tasks: Cascade works best on focused goals
- Keep projects organized: Better structure = better understanding
Windsurf for Different Roles
Frontend Developers: Cascade excels at component generation and styling
Backend Developers: Strong at API design and database operations
Full-Stack: Handles end-to-end feature development
DevOps: Good at infrastructure code generation
Future Roadmap
Windsurf team announced:
- Deeper VSCode integration
- More sophisticated agents
- Team collaboration features
- Custom model support
Conclusion
Windsurf represents the newest evolution in AI-native IDEs, with agent capabilities differentiating it from competitors. For developers comfortable with newer tools and wanting agentic workflows, Windsurf is worth exploring. Its $15/month price point makes it accessible for testing.
