Hey folks, AI programming tools are becoming real game-changers! But most of them are made overseas, and sometimes they just don't feel quite right. Qwen Code is different. It's an AI programming assistant from Alibaba Cloud, and it not only writes slick code but can also directly call various Alibaba Cloud services. It's a blast to use!

Today, I'm sharing 20 practical tips for Qwen Code that you'll actually use in your daily development. These are guaranteed to make your programming efficiency take off! (This is all practical stuff, so I recommend bookmarking it for later.)

How to Install Qwen Code?

Installing Qwen Code is actually pretty simple. Here’s a detailed breakdown:

Step 1: Register for an Alibaba Cloud Account

• Go to the official Alibaba Cloud website and register for an account (if you don't have one).
• Complete the real-name verification for more stable usage.

Step 2: Find Qwen Code

• Log in to the Alibaba Cloud console.
• Search for "Tongyi Qianwen" or "Qwen Code".
• Choose your development tool (VS Code, IDEA, and Vim are all supported).

Step 3: Install the Plugin

• Download the corresponding plugin package.
• Follow the installation prompts.
• Configure your API key.

Why Choose Qwen Code?

• Excellent Chinese support makes writing comments and documentation easy.
• Directly calls Alibaba Cloud services, so you don't have to set up your own environment.
• It's more affordable than many international tools.
• Fast domestic network access means no lag.

1. Be Precise with Your Descriptions for Better AI Understanding

Stop using vague commands like "fix this bug." Try to be as specific as possible with your requests.

Practical Example:

❌ Incorrect Example:
Fix this bug

✅ Correct Example:
Fix the null pointer error that occurs when a user tries to log in without a password.

Why does this matter?

• The AI can understand your needs more accurately.
• It reduces back-and-forth communication time.
• The generated code is more likely to meet your expectations.
• It avoids generating irrelevant code.

2. Break Down Large Tasks into Small Steps for Higher Efficiency

For small tasks or modules, you can send the entire requirement to the AI at once, and it can deliver the result in one go, which is more efficient.

However, for larger requirements with a long implementation process, it's better to break down complex tasks into smaller steps:

Practical Example:

Step 1: Create a new endpoint for the user API.
Step 2: Add necessary validation for the request fields.
Step 3: Write test cases for this endpoint.
Step 4: Update the API documentation.

Why execute in steps?

• AI context windows have limits; long requests might get truncated.
• You can review/test each step before telling the AI to proceed to the next one.
• It reduces repetitive explanations and communication costs.
• It lowers the probability of errors.

3. Let the AI Understand the Project Before It Starts Working

Before modifying code, let Qwen understand your codebase first. This will help it assist you more accurately and efficiently in development and optimization.

Practical Example:

Analyze the database table structure.
How are errors handled in this application?
What is the architecture of this project?

Why let it understand first?

• The AI can better grasp your business logic.
• The generated code will be more consistent with the project's style.
• It avoids breaking the existing code structure.
• It improves code quality and consistency.

4. Master Shortcuts for More Efficient Operation

Mastering shortcuts can significantly boost your efficiency:

Common Shortcuts:

• Type / to see all slash commands.
• Use the up and down arrow keys to browse command history.
• Use the Tab key for command auto-completion.
• Use Option + Enter for a new line.
• Use Ctrl + C to exit the terminal.

Practical Tips:

/help    # View help information
/clear   # Clear conversation history
/cost    # Check usage costs
/compact # Compact the context

5. Use Permission-less Mode to Avoid Frequent Confirmations

Are you tired of Qwen Code stopping midway through a task to ask for your permission? It can seriously disrupt your workflow.

Launch Command:

qwen --dangerously-skip-permissions

Set an Alias (Recommended):

alias qwen='qwen --dangerously-skip-permissions'

⚠️ Security Warning:

• This mode skips all permission checks.
• It's recommended for use in personal development environments only.
• Use with caution on company projects.
• Regularly check the content of generated files.

6. Press ESC to Stop Incorrect Operations at Any Time

If you give Qwen Code a wrong command and want it to stop, just press the ESC key.

Practical Tip:

• Press ESC to immediately stop the current task.
• The terminal will display "Interrupted by user."
• You can then enter the correct command.
• Avoids wasting time waiting for an incorrect result.

7. Resume Previous Sessions to Keep Your Work Uninterrupted

Qwen Code offers multiple ways to resume a previous conversation:

Non-interactive Mode:

qwen --continue  # Automatically continue the most recent conversation
qwen --resume    # Show a history of conversations to choose from

Interactive Mode:

/resume  # Resume a historical session

Practical Tips:

• Use the up and down arrow keys to select a past session.
• You can return to any previous conversation.
• Supports cross-project session recovery.
• Avoids re-explaining your requirements.

8. Smart Memory Management and Personalized Configuration

Qwen Code provides three memory locations, each for a different purpose:

Memory Type	File Location	Description
Project Memory (Shared)	./QWEN.md	Instructions shared by the project team.
User Memory (Global)	~/.qwen/QWEN.md	Personal preference settings.
Project Memory (Local)	./QWEN.local.md	Personal project settings (deprecated).

Practical Configuration:

# Edit the memory file
/memory

# Set responses to be in Chinese
echo "Please always answer me in Chinese." > ~/.qwen/QWEN.md

Memory File Content:

• Frequently used bash commands.
• Core files and utility functions.
• Code style guides.
• Testing instructions.
• Development environment settings.

9. Operate Git with Natural Language, Say Goodbye to Complex Commands

In Qwen Code, Git operations become conversational, so you don't have to remember tedious commands:

Practical Examples:

What files have I modified?
Commit my changes with a reasonable, descriptive message.
Push this branch to the remote.
Create a new branch: feature/test.
Delete this branch and switch to the master branch.
Show a list of all files from the last 3 commits.

Git Integration Advantages:

• Operate Git with natural language.
• Automatically generate commit messages.
• Smart branch management.
• Automatic conflict resolution.

10. Linux Smart Assistant, Handle Complex Commands with One Click

Since Qwen Code is used in the terminal, you can also use it as a Linux smart assistant:

Interactive Mode:

List the top 3 .java files with the most lines.
Find the file that takes up the most disk space.
Count the lines of code.

Non-interactive Mode:

qwen -p "List the top 3 .java files with the most lines"

Linux Integration Advantages:

• No need to remember complex Linux commands.
• Smart command generation.
• Automatic error handling.
• Supports complex queries.

11. Monitor Costs to Keep Your Spending in Check

Use the /cost command to view your current session's usage:

Basic Command:

/cost  # View current session's cost

Advanced Tool (Recommended):

# Install the qcusage tool
sudo npm install -g qcusage

# View costs for a specific date
qcusage -s 20250701

# View costs in real-time
qcusage blocks --live

Cost Control Tips:

• The personal plan costs a few dozen RMB per month, cheaper than international tools.
• The enterprise plan supports team sharing, reducing per-person costs.
• Regularly use /compact to compress the context.
• Batch similar tasks to improve efficiency.

12. Smart Compression to Save Costs and Speed Up Responses

Qwen Code provides the /compact command for compression:

How to Use:

/compact  # Manually compact the context

Automatic Compression:

• By default, automatically compresses when the context exceeds 95% capacity.
• The remaining percentage is displayed in the bottom right corner.
• Automatically compresses when it reaches 0%.

Compression Advantages:

• Reduces the size of the conversation context.
• Lowers token usage.
• Improves response speed.
• Saves costs.

Best Practices:

• Regularly use /compact to manually compress.
• Use the clear command periodically to reset the context.
• Break down complex tasks to avoid an overly long context.
• If you're a big spender, you can ignore these optimizations.
