ericwang915 Code Runner
When to Use
- Run or test Python code snippets
- Evaluate expressions (e.g., "calculate 2^100")
- Prototype logic or verify algorithms
- Execute user-provided Python code safely
When NOT to Use
- Running shell commands or external programs — use
run_command/ terminal - Executing non-Python code (JavaScript, etc.)
- Code requiring heavy I/O, network calls, or persistent state
- Editing or analyzing code without running it
Setup
No API keys or credentials needed. Uses the bundled run_code.py script.
Usage/Commands
python {skill_path}/run_code.py [options]
Input methods:
| Method | Example |

Notes
- Code runs in a subprocess (not eval/exec in the agent process) for safety
- Timeout prevents infinite loops
- Working directory is the project root
- For shell commands or other languages, use the terminal directly
