try:
“Write a Python function that takes a list of integers and returns a new list with only the even numbers.”
Include details like input types, expected output, error handling, and the programming language.
Break Down Complex Tasks
If your coding request is complex, divide it into smaller parts. First, ask for a basic version. Then follow up with prompts like:
“Now add input validation,”
or
“Optimize it for performance.”
Request Explanations
Don’t just copy code—ask Claude to explain what it’s doing. Use prompts like:
“Can you explain each step in this code?”
This helps you learn and ensures you understand what the code is doing.
Test All Output
Claude does not run or validate the code. Always test the output in your own IDE to make sure it works as expected.
Avoid Sensitive or Private Code
Never submit private data or sensitive business logic to any AI tool, including Claude. Use it responsibly.
By following these best practices, you’ll maximize the value Claude brings to your coding workflow.
Limitations and Cautions
While Claude AI is a powerful tool for code generation, it’s important to be aware of its limitations. Understanding these will help you use the platform more effectively and avoid potential issues.
First, Claude does not execute or test code, so it may occasionally return snippets with syntax errors or outdated practices. Always review and test the output in your own development environment to ensure functionality.
Second, Claude’s code suggestions are based on general programming knowledge. It may not always follow best practices for specific frameworks, libraries, or advanced use cases unless clearly prompted. For complex tasks, you may need to guide it with detailed instructions or multiple refinements.
Claude AI also has no IDE integration, unlike tools like GitHub Copilot. This means it won’t offer real-time suggestions while you type in your editor—you need to switch between your browser and coding platform.
Lastly, avoid using Claude for confidential or sensitive business logic. Like all AI tools, user prompts may be used for future training unless you’re using a privacy-protected or enterprise version.
In short, Claude is a smart assistant—but not a replacement for human review, testing, and security awareness.
