# execute_code

> Execute approved Python code inside an open Parashell transaction.

## Signature

```python theme={null}
execute_code(code: str, reason: str, expected_action: str, transaction_id: str) -> list[TextContent | ImageContent]
```

Descriptor: `run approved python code`

## Invocation

```json theme={null}
{
  "code": "doc.recompute()",
  "reason": "Recompute the active document after updating its parametric feature values",
  "expected_action": "Recompute all pending document features",
  "transaction_id": "<transaction-id>"
}
```

## Operational notes

The call waits for the queued Parashell GUI task to finish instead of reporting a timeout while code continues running. The transaction must remain open. Successful execution records one operation before the response is delivered. A raised exception removes objects added by that call while preserving earlier successful edits in the transaction.
