Code Execution

Executes JavaScript or Python in an isolated environment.

Requirements

• Docker (preferred): full sandbox, no network, 128 MB RAM, 5 s timeout.
• Fallback: JavaScript only via Node vm when Docker is missing (no import/require/process in sandboxed path).

Security

• Network disabled in Docker mode.
• Confirmation when source contains import, require, or process.
• Python requires Docker; there is no VM fallback for Python.
• Scout may block via SCOUT_BLOCKLIST.

Language detection

If language is omitted, Carina infers from syntax (def, import -> Python; otherwise JavaScript).

Example

"Run this JavaScript: console.log([1,2,3].reduce((a,b)=>a+b,0))"

Returns

{
  "output": "6",
  "error": null,
  "exitCode": 0,
  "executionTime": 42
}

Non-zero exit codes populate error with stderr.
