Detector tests

This benchmark is a reproducible test suite of synthetic examples. It does not measure all real-world prompt-injection attacks.

The repository contains the fixture text and expected behavior. Run the automated test command to evaluate the same detector used by the scanner; results can change as rules evolve.

Live detector results

These synthetic tests demonstrate known detector behavior. They do not represent complete real-world prompt-injection coverage. A passing test does not guarantee that novel, obfuscated, multilingual, or context-dependent content is safe.
