Code Runner

Code Runner Skill

Execute code using the exec tool in the sandbox environment.

Available Languages

Python 3

python3 -c "print('hello')"
# Or write to file and run:
python3 script.py

Install packages with: pip install package_name

Shell/Bash

echo "hello" && ls -la

Node.js (install first if needed)

# Install node if not available
apt-get update && apt-get install -y nodejs npm 2>/dev/null || apk add nodejs npm 2>/dev/null
node -e "console.log('hello')"

Guidelines

• Always execute code immediately — don't just show it
• For multi-line scripts, use write_file to save then exec to run
• Install missing packages automatically without asking
• Show the complete output to the user
• If code fails, analyze the error and fix it automatically
• For Python one-liners, use python3 -c "..."
• For complex scripts, write to a .py file first

Error Handling

• If a command fails, check the error and try to fix it
• Common issues: missing packages (install them), syntax errors (fix them), permission denied (use appropriate paths)
• Always retry at least once after fixing the issue
