# No dynamic SQL string execution

Agents glue SQL together with f-strings. That is injection and a broken plan cache.

## Do

```python
cur.execute("SELECT id FROM invoices WHERE status = %s", (status,))
```

## Do not

```python
cur.execute(f"SELECT id FROM invoices WHERE status = '{status}'")
```

## Enforce

CI gates this rule (`enforcement: checker`):

```bash
python3 scripts/check.py --repo-root . --pack python --rule python.security.no-dynamic-sql-execution
```
