What problem does it solve?

The Code Runner skill enables you to execute arbitrary code snippets across JavaScript, TypeScript, Python, and shell, with built-in timeout protection and output capture to support testing, prototyping, and automation workflows.

Core Features & Use Cases

• Multi-language execution: Run code snippets in JS, TS (via TSX), Python, and shell from a single tool.
• Deterministic execution with safety: Enforce timeouts and capture stdout and stderr for reliable automation and benchmarking.
• Use Case: Validate a function across runtimes, benchmark a snippet, or prototype a script before integrating into a larger workflow.

Quick Start

Use the code-runner skill to execute a simple JavaScript snippet like console.log('Hello') or a Python snippet like print('Hello'), and verify the outputs.
