Cursor Usage Guide: Best Practices for AI Programming Assistant

Cursor is an AI-powered programming IDE based on VS Code, integrating powerful AI capabilities. This article will share usage tips and best practices.

What is Cursor?

Cursor is an AI-first code editor that deeply integrates AI capabilities on top of VS Code:

• Tab Completion: Intelligent code completion
• Chat: Conversational programming with AI
• Cmd+K: Inline code editing
• Composer: Multi-file editing

Connect to Ciyuano Token Circle

Cursor supports custom API endpoints; you can use domestic models by connecting to Ciyuano Token Circle:

1. Open Cursor Settings
2. Select Models → OpenAI API Key
3. Enter your Ciyuano Token Circle API Key
4. Set Base URL to

Usage Tips

1. Make Good Use of Cmd+K

Select code and press Cmd+K to describe modification requirements in natural language, and AI will automatically modify the code.

2. Provide Context

Use @ in Chat to reference files, documents, or code repositories, helping AI better understand your project.

3. Use Composer

For cross-file modifications, use the Composer feature to let AI edit multiple files simultaneously.

4. Custom Rules

Define project specifications in the .cursor/rules file to make AI follow your coding style.

5. Choose the Right Model

• Daily coding: DeepSeek V4 Flash (fast, cheap)
• Complex tasks: Claude Sonnet 4 (strong reasoning ability)
• Code review: GPT-4o (multimodal understanding)

Best Practices

1. Describe requirements first, then write code: Let AI understand your intent
2. Complete in steps: Break complex tasks into smaller steps
3. Review AI-generated code: Don't accept blindly
4. Make good use of version control: Commit before AI modifications
5. Keep learning: AI is a tool, not a replacement

Summary

The combination of Cursor + Ciyuano Token Circle multiplies programming efficiency. Choose the right model, master the correct usage methods, and the AI programming assistant will become your most powerful productivity tool.
