agent-skill-code-runner

This skill addresses the pain point where developers cannot directly execute code to verify logic during AI conversations. In real-world development, developers often need to quickly test code snippets, debug algorithms, or validate syntax, but traditional methods require manually switching to a terminal or IDE, disrupting the workflow. The Code Runner Agent Skill allows AI agents to run code directly without leaving the conversation environment.

Usage is straightforward: simply copy the skill directory to .github/skills/code-runner in your project, and the AI agent will automatically detect and enable it. After that, you can use natural language instructions to have the AI execute code, such as "Run this Python code: print('Hello')" or "Calculate the first 10 terms of the Fibonacci sequence in JavaScript." You can also run it directly via the script command line: echo 'code' | node scripts/run-code.cjs <language>.

It is ideal for teams or individuals who frequently need to validate code across languages, especially those already using AI coding assistants like GitHub Copilot or Claude Code. Full-stack engineers, backend developers, and test engineers can all benefit—whether for quickly testing interface logic, verifying algorithm correctness, or troubleshooting code issues.

We recommend installing this tool uniformly across the team and ensuring all members have the corresponding language runtime environments installed locally. Note that it primarily relies on local interpreters/compilers, so the PATH environment variable must be configured in advance. It also supports custom timeout settings (default 30 seconds) to prevent infinite loops.
