Decision brief

Good fit when

When you need to methodically test system prompts in generative AI applications for potential security flaws.
To ensure safety and security of GenAI apps by identifying vulnerabilities through prompt fuzzing.

Avoid when

If your project does not involve generative AI applications or does not require prompt testing for security reasons.
For tasks unrelated to the hardening and evaluation of system prompts, as ps-fuzz is specifically designed for this purpose.
