Sandbox

Lets an agent execute Python, Bash, JavaScript, or shell scripts in a kernel-isolated gVisor sandbox on Kubernetes. Each execute_code call creates a fresh pod and deletes it after — state is not persisted between calls.

What it can do​

  • Data analysis and transformation
  • Algorithm implementation and verification
  • File generation (CSV, JSON, reports)
  • Lightweight web scraping (requests + beautifulsoup if installed)

Always check exit_code: 0 is success. On failure, read stderr, fix the code, retry.

How to get credentials​

None — Sandbox is built-in, no setup required.

Fields to fill in FlyMyAI​

None.

Troubleshooting​

  • Missing package — the sandbox has a curated set of pre-installed packages. Install on-the-fly in Python (pip install via subprocess) only for small, pure-Python libraries; large binary wheels may fail.
  • Timeout — each call has a wall-clock limit. Split long jobs into chunks and write intermediate results to files.
