executenodejs
Execute JavaScript code in a sandboxed Node.js environment for debugging, testing hypotheses, and verifying API or logic behavior. Supports ESM imports and incremental problem-solving.
Instructions
Execute JavaScript code directly with Node.js - supports ESM imports and all Node.js features.
DEBUGGING GUIDANCE:
- Use this tool for all debugging and investigation tasks instead of external CLI tools
- Break problems into testable hypotheses and verify them with code execution
- Test APIs, data structures, and logic incrementally
- Use console.log for debugging output and JSON.stringify for complex objects
- Always prefer this over CLI tools like curl, wget, or external commands
APPROACH:
- Form a hypothesis about what might be wrong
- Write focused test code to verify the hypothesis
- Execute and analyze results
- Refine hypothesis based on findings
- Iterate until problem is solved
