Code Runner Skill

Use this skill to quickly execute a piece of code to test logic, write a script for the user, or run built-in system tools.

Workflow

1. Determine the language required (Node.js, Python, Shell, Go, etc.).
2. Write the code snippet to a temporary file using the write tool (e.g., in /tmp/test-script.js).
3. Use the bash tool to execute the script (e.g., node /tmp/test-script.js).
4. Capture the standard output and standard error.
5. Provide the execution result to the user.
6. Clean up the temporary file using bash (rm /tmp/test-script.js).

Example Usage

If the user asks "How do I reverse a string in JavaScript? Show me.", write a script with the solution, run it to verify it works, and show them both the code and the verified output.
