When NOT to use llm-guard
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- - If you are working in a low-security environment or with small-scale projects where advanced security mechanisms are not necessary.
- - In cases where integrating external libraries and ensuring Python version compatibility may introduce complexities that outweigh the benefits.
