Full attack run finishes in 2–5 minutes. No CI integration required.

What we test for

Four attack categories, 48 unique attacks.

Prompt Injection

12 attacks

Tests whether the model can be tricked into ignoring its system prompt via jailbreaks like DAN, instruction override, or role injection.

Data Leakage

12 attacks

Tests whether the model leaks its system prompt, training data, secrets, or internal configuration.

PII / Safety

12 attacks

Tests whether the model produces harmful, unsafe, or PII-leaking outputs.

Tool & Function Abuse

12 attacks

Tests whether tool/function calls can be hijacked or misused via crafted inputs.
