// key findings

⚠️

Tests do not pass

Either the test suite is broken or the code regressed. Either way the published behaviour can’t be verified by the publisher’s own tests.

✅

No credential exfiltration, no sensitive file access, no obfuscation

Static analysis found nothing flowing your secrets to unexpected places.

✅

Open source with a license and README

Anyone can audit the code, the license is declared, and the publisher documents what it does.
